Metal structures constitute the most widely used construction system in most countries. It is ideal given its malleability, hardness and resistance features. Its structural efficiency is very high, due to the fact of being produced in sections with the most convenient shape so as to withstand flexion and compression. At Exafan, we consider that the most convenient systems for our designs are the ones named type IPE and the ones named type C, given that their performance is perfectly linear and elastic, which makes the structure performance in relationship with this material very predictable. The material high ductility enables to redistribute an effort concentration. Building structure based on a steel structure with a European standard metal framing type IPE; it was chosen thanks to its flexibility, quality warranty, mechanic resistance and adaptability to the Exafan Company´s customized building designs. The structure is made of steel profiles type IPE, screwed in on sight and with galvanized beams type “C”.  Metal structures IPE

Poultry farms must have an adequate thermal insulating system in order to make the breeding process in an efficient and profitable way. A correct insulation as well as a good environmental management control system is critical in terms of cost reduction and improvement of the production index. In order to efficiently save power inside the farming buildings, we must monitor and correctly check the environmental control system, something we are truly specialist at Exafan; however, in order for this practice to be really efficient, it is essential to begin by correctly insulating all the elements included in the buildings. Roofs, internal insulation, lateral enclosures, and mobile accesses, are the elements providing the building with the convenient insulation level required so as to maximize the control process.

The global insulation level of a building is defined by the weighted average coefficient of all the enclosures surrounding the building. The turnkey project solution offered by EXAFAN makes such insulating level unbeatable, given its concern care regarding the election of the materials, their quality and added value given the company´s experience as a leader in the construction sector of farming buildings. Exafan supplies all the external equipment required according to the highest insulation standards, elements such as air extractors, air inlets and building access gates have been designed to successfully face the most extreme environmental conditions possible.

Insulation in farming facilities shaped by the roofs, enclosures, and climate control elements such as air inlets and extractors.

Insulating a farming building is a requirement because of the following reasons: - In order to efficiently contribute for an energy saving program. - Higher animal comfort. - Building better maintenance. - Better environmental quality. - Less fodder consumption. Pag.-8

Insulation for the roof with a simple sheet, air chamber with a glass wool, and a false ceiling made of a panel sheet with an insulating nucleus PUR or PIR.

Materials used for a correct insulation Polyurethane: It is an insulating synthetic material for different construction applications; its high insulating power as well as extreme lightness, makes it an ideal material as an insulating nucleus for the enclosures of the roof or perimeters. Very low thermal conductivity synthetic material; it is the lowest one considering all the insulating materials. This is important given that it allows a higher insulation degree with less thick material Polyisocyanurate: the combination of the polyol and isocyanate elements gives some very specific features to the material due to the different chemical structures. The insulating PIR sheets are used given their higher thermal stability features and resistance regarding fire. Rock wool: or glass fiber, it is a material made of volcanic rock. It is mainly used as a thermal insulator as well as passive protection device against building fire, due to its fibrous multidirectional structure, which allows storing relatively immobile air inside. The structure made of rock wool includes some dry and stable air inside, therefore it works as an obstacle to the transfer of heat, insulating against low and high temperature.



The metal roof is the most delicate part of any farming construction building subject to a strong loss of energy in winter and very exposed to sun radiation in summer. The design and installation of the metal roof require high degrees of reliability and endurance. A warranty that EXAFAN confirms on the basis of its technical know – how acquired in the industrial construction sector for many years.

We apply our demanding quality values along with an experience in the treatment of steel, sheets, sandwich panel and waterproofing. We offer different kinds of roof for farming buildings.

The building roof is a gabled roof type. The roof parts are fixed to the belts by means of the galvanized self – drilling screws supplied with also galvanized washers in an armed bituminous product. The material used complies with the corresponding current regulation. We always bear in mind the manufacturer´s specifications, such as the separation between the belts and the minimal lap.

For a better protection of the facades, the tilted roof is extended further on the façade plan by shaping an eave.

Given that it is a material made on sight, customized, it does not require any cut, it penetrates through any groove we wish, it doesn´t leave any junction and does not generate any waste Pag.-12

This option is only considered when the insulation provided is not enough for the roof, as long as we deal with favorable environmental conditions, very little aggressive in terms of temperature variations.

Insulation Enclosures

Part of our farm success is based on the correct building insulation, the energetic efficiency of it will mark the pace of our business, therefore, the importance and priority Exafan gives to the quality of the materials used during the construction. A well insulated building will help achieving the comfort parameters recommended more easily, therefore, we will be able to improve the performance of the climate control equipment in order to reach such parameters; insulating the lateral enclosures is as important as the roof insulation, which along the front sides and the quality of the elements – mobile ones such as gates and air inlets – guarantee a relevant saving in energy.

The set of elements shaping the farming building: walls, roof, floors, and carpentry, have the protection of the animals inside face to environmental conditions from outside as their main function. These elements will have the required hygrothermal features helping to keep the best comfortable conditions possible, providing the animals with a sufficient welfare level to develop at their maximum production potential.

Galvanized and lacquered lateral gable; It is applied on the building areas where the air inlets are located. It is composed of some simple lacquered metal roof sheets with a maximum length marked by the distance between the arcades; it is fixed to the structure shed by means of regular as well as galvanized screws and bolts. Its purpose is avoiding a negative influence by the external wind and achieving an exhaustive control of the air flow and speed.

The election of the poultry farm location is subject to a series of conditions: regulation, infrastructures (access, water, and light), elimination of the waste, etc. In general, we should search for a healthy land, protected from strong wind, but sufficiently airy, dry and well drained, this avoids additional problems since the very beginning of the installation.

In order to avoid such negative influences on the calculations of our ventilation system, we recommend taking into account some natural windbreak barriers with the purpose of avoiding a dependency on them. Exafan provides to its rooms with a lateral gable that tries to minimize the adverse wind effects on the ventilation calculations.


Protection 20 times h

The air is forced inwards the room in such a way that it gets inside the building at the convenient speed and direction.




Exafan supplies state – of – the – art technological projects for its clients in order to obtain the highest farm production level pos-sible while taking care of the slightest detail so that the animals enjoy a similar natural habitat to what they are used to, actually even better. The nature of our products is technical, but the services rende-red and client´s assistance has to do with the personal side of it. At Exafan, we work with the client on a collaborative basis, con-sidering his needs and suggestions as an inspiration and impro-vement source, generating a close bilateral relation which will ultimately turn into a successful project.



The buildings designed by Exafan are conceived to locate all the ventilation system and absorb the vibrations and tensions caused by these, their distribution is made with the purpose for the direction, height, and uniformity of the air flows to be ideal while searching for the highest energy power efficiency possible.

Ventilation has as purpose: to provide with oxygen inside the room, eliminate CO2 , dust and other gases, eliminate the water steam caused by the animal breath and the feces as well as control the temperature inside. • Dynamic ventilation: it is made by means of fans moving the required air during each production stage.

Our specific dark buildings for the rebreeding process have some light trap systems for the accommodation of so many delicate animals under total dark conditions and with the purpose of breeding a uniform herd at a compatible weight and aiming at sexual maturity as goal. It is essential for the building finishing to be perfectly watertight in order to avoid any slit where light could get through.


Insulating lids, they provide the building with the highest water tightness possible while shutting any leaking caused by the fans not in use.


Exafan installs energy efficient motors IE2 in our fans in compliance with the regulation regarding power efficiency.

The motors used for the Exafan fans comply with the regulation required in each country, offering different alternatives according to the energy requirements, kind of facilities or animal rearing typology. The efficient use of energy is something that increasingly takes part in our daily life, which enables to decrease the energy costs and it is also beneficial for the environment.

Specific For those facilities where the animal rearing period is relatively long and the maintenance or cleaning activity of the equipment cannot be made as often as it should be, the motors equipped with a cooling fan may become a problem since they usually work under dusty conditions, in these circumstances, dust tends to accumulate on the rear grid and blocks any kind of air flow, which forces the motor to work at a high temperature and shortens its useful life. For this kind of scenarios, as for example in the case of internal housing equipment for laying hens, Exafan has completely sealed fans available that offer completely satisfactory results under the mentioned working conditions according to our own experience.

TENV Motors The motor irradiates its excessive heat through the carcass; therefore, the motor has extra flaps in order to transfer the heat.




Exafan air inlets have been designed to obtain an optimal distribution and dosing of the ventilation air flow. The VEA air inlet has been built in highly dense polyurethane, with screws and bolts made of stainless steel, materials all of them resistant to corrosion, on top of ensuring an unbeatable insulation level and therefore, avoiding thermal bridges as well as the annoying condensation.

Regarding the maximum ventilation, the air flow is divided in two in a progressive and proportional way; it is beneficial during hot periods, since the more the temperature increases, the more air flow is carried to the animal area.


Regarding the minimum air flow, it is carried towards the upper part and mixed with the air already existing there, preventing the cold air from coming down and fall over the animals.

The synergy level generated when widening the air inlets specifically designed by Exafan is essential at the time of achieving the required precision level, such level is not possible to achieve if another kind of more generic air inlet is used.

High density polyurethane The Exafan air inlets type VEA are made of high density polyurethane, with stainless steel screws and bolts.


Insulation The frame has a contact to the blade on all the edges, insulation system and airtightness, as for example locking strip joints.

solar tube

The system receives the sun light through a dome and carries it by means of tubes whose internal part is highly reflective due to the fact that they are partially made of silver. The light carried inside the building is blurred in the room by means of a diffusing recessed light fixture with a very aesthetic and the same time functional design.

Advantage WITHOUT THERMAL OR ACUSTIC TRANSFER This system has been designed in such a way that acoustically speaking, the noise is not transmitted through it thanks to the sealed chamber shaped inside the tube avoiding the transmission of any external noise, the same way and thermally speaking; the loss of heat in winter or cold in summer is avoided.



It is possible to lighten the place desired.

The lightening provided inside by means of this system is free of noxious rays. That is why it is a natural and healthy kind of light. The installation of a solar tube is executed in around 4 hours in case of a conventional facility, as a consequence, we may have natural light very fast and anywhere we want.


Differential pressure meters

The differential pressure meters help to better control the farm resources when providing a reading if the air inlet speed within the building is the correct one. The DP is a differential pressure meter that by means of obtaining a reading from outside the building may deduct the differential pressure caused by the ventilation inside the facilities. Once the information obtained, the DP gives a signal of 0/10Vcc or a signal of 0/5Vcc for the ventilation control equipment to determine the opportune corrections in order to get the best working conditions possible.

The access to a correct feeding process is one of the fundamental aspects in order to guarantee the poultry welfare. The presence of fodder is a critical point, under no circumstance, the synchronization of the supplying system may be deficient to a point for the farm to remain with no feed. In order to avoid this situation, Exafan provides its facilities with state – of – the art fodder presence control devices for the silos.

Silo flat sheet silo, Corrugated sheet silo, Silos made of polyester

Automatic silo decompression. The feed must be transported by means of the vehicles mainly aimed at this activity, your vehicles and workers should not access the facilities. In order to make this supply easier from outside the safety area in non - specialized trucks, there is a possibility of acquiring the silo including a pneumatic loading system.

Control to fill in and replace the fodder, on top of interpreting the feeding consumption expected for the poultry according to the growing curve and with the purpose of detecting any problem during the normal ingestion of the feed. Essential to avoid the lack of feed in the silos.


Feeding systems

Independently from the feeding system chosen, its design guaranteeing the supply to all the animals with sufficient space and convenient conditions is critical. The feeding distribution and proximity of the feeders vis-Ă -vis the animals are key factors if we wish achieve the programmed feed consumption rate.

The corporal weight control of the poultry is achieved by continuously adjusting the quantity of feed supplied to the chicks while taking the real weight of the poultry and their relationship with the ideal curve weight as a reference. Exafan´s support even gets to the point of advising the producers on how to manage the feeding system with the purpose of providing a defined program including the entire range of balanced diets meeting the nutritive requirements of the animals during their whole development stages, in order to obtain optimal efficiency and profitability without compromising the animal welfare or the environment.

According to the kind of poultry we wish to breed, we will choose the feeding system:

Thanks to the feeder Lyra, changing the kind of animal, race or cycle period is no problem any more.



It is designed to accompany the turkey during its growth since the very first day. It has two interchangeable pans analyzed for the different stages of the breeding period.

The Superpito feeder is dimensioned to feed according to the turkey wish since the very first days preventing it from getting inside. It is efficient and economic on top of very easily installable.

Here, hens are particularly aggressive and vigorous. The fodder rationing gets them nervous; therefore, it is an ideal feeder, robust and with a wide area allowing the hen to easily access.


FLATLINE FEEDING SYSTEM Great reliability and flexibility. Easy management and maintenance Exceptional price – quality relationship

It is very versatile, all the components are easy to install and situate where necessary. Some accessories may be added at any time so that the system can be adapted and get increased according to the requirements. The transportation unit can be added to the hopper. Made of a painted steel sheet. It is available in different versions, of 1-2-3-4 tracks, with an approximate capacity of 150 kg. There are extensions available for the hopper in order to increase the capacity in sections of around 100 kg. The supporting legs are easily adjusted in terms of its height.

The feeding system is completed with specific feeders for hens – LYRA –

Hanging feed transportation system. The feeding transportation system FLATLINE hangs from the building structure with the purpose of lifting it during the cleaning operations.

The air distribution system is an ideal system for breeding fowls of chicks experiencing a feeding restriction (they only eat once a day and little quantity), since at the time of distributing the feed uniformly through the entire surface of the shed, animals get access to the feed without competing against the others. Fowls are bred more uniformly and the mortality level decreases. The hopper does not destroy the granulated feed, that is why the hen finds it easily, and the distribution system in rain mode does not damage the eyes of the animals. The number of animals per square meter is higher as there is no obstruction on the ground, which considerably improves the animal welfare.

The supply of clean and fresh water with adequate flow is fundamental for the poultry production. Without an adequate water consumption level, the fodder consumption will decrease and the general performance of the animals compromised. At Exafan, we also take care of the animals having a comfortable access to the drinkers, which must be well located and accessible at a distance below 1 meter during the first life stage. Water must be fresh and good bacteriological quality as well as chemically treated.

Drinkers with / without drip cup

In order to achieve a transformation index, a correct water supply is essential. Nipple drinkers present a polluting rate below the open drinkers. They must be adjusted at the required height and pressure for fowls of different size. Nipple made of PVC and made of stainless steel.

For an optimal performance of the productive units, we recommend using a system of drinkers with drip cup, the probability of pollution and waste of water is below a system without drip cup.








At Exafan, we take care of our buildings reflecting the natural environment whenever possible, so that animals behave according to nature; in compliance with the current regulation welfare, we provide our facilities with elements such as perches, layers, nests, etc. to sump up, spaces designed for the animals to perform under the best conditions possible.

Internal housing equipment for broilers and layers AVIO is a laying nest designed for a double use, broilers and layers. The care and detail we have taken regarding the design of the AVIO provides the hens with a comfortable environment for the laying process. Nests do not damage the eggs and are stored safely and clean. The versatility of the laying nests AVIO enable them to position back to back along the length of the farm. They also enable the existence of a certain space between the laying nests allowing the animal free circulation. The hens may enter through any side of the block of nests. Eggs are laid on a special synthetic coating and roll very over easily on the central collection channel.

Each nest floor is galvanized with a mesh and a drilled blanket �Astrturl�, both sides can be easily removed for their cleaning. We may avoid the hens to remain on the nests too long. Inside each nest, there is a mesh panel, which can be advanced automatically for the hens to move outside the laying nest. This way is possible to keep the nest empty. The eggs pass through a wide and rigid belt made of polypropylene and arrive healthy and safe to the designed place as the collection point. The belt speed can be electronically adjusted according to the existing number of eggs on the conveyor belt. A series of holes on the collection belt removes any dirtiness and guarantees the eggs will not roll over during the recollection process.

Internal housing equipment to breed the chicks GEMINI The GEMINI is an aviary to breed the chicks, it was designed to train the future layers to be placed in these aviaries. Only the chicks bred in these aviaries behave conveniently as layers in these aviaries. Higher density of fowls and easy management. - Adjustable drinkers - Belts to remove the hen feces - Grids - Lightning channel - Perch





Accommodation system for the laying hens on the floor LIBRA The LIBRA facilitates the fact of breeding more hens per square meter than a breeding system on the floor. The hens may move around freely inside the building and according to the stratified cage standards. - Feeders - Adjustable drinkers - Belts to remove the feces - Nests - Lightning tubes - Perch - Balconies (optional)
