Energy efficient and environmentally friendly air handling units

IV Produkt develops, manufactures and sells energy efficient and environmentally friendly air handling units. We’ve been doing so since 1969. Alf SjÜberg, owner and Senior Advisor and Mattias SjÜberg, owner and CEO.

IV Produkt invests considerable resources in research and we are known for our high rate of product development. Developing energy efficient products is close to our hearts and today we are leading the market in that domain. Our high rate of product development is also reflected in our corporate growth. In Sweden, IV Produkt is a well-reputed trademark and during the last five years we have strikingly increased our market share. Currently we have approximately 25-30 percent of the Swedish market, and have sharp plans to expand on selected export markets. We have always had a long-term strategy for growth both in Sweden and in export markets. We think that it is to our advantage to have product development, marketing and sales under one roof. The ability of our product development and marketing departments to work together is an important factor that enables our high rate of development.

We make great demands on ingenuity when we develop our products and streamline our manufacturing procedures. We do all this so that our clients will be able to save on the resources needed for installation, operation and maintenance. We are constantly involved in making our products as energy efficient as possible. The Life Cycle Cost (LCC), the collective cost for purchase, operation and service, as well as environmental concerns are always included as a natural part in our development of new products and product selection softwares. Our goal is to be able to offer our customers the lowest possible Life Cycle Cost (LCC).

Energy-saving passive houses

Pictures taken by Givakt on behalf of Hyresbostäder i Växjö AB

– an innovative housing form

The passive houses Portvakten Söder in Växjö are leasehold flats offering the tenants innovative, modern and environmentally friendly living. This project has received vast recognition from the European Union for bringing front edge technology into full scale production. PORTVAKTEN – Växjö, Sweden

Flexomix in a Passive house version A centrally located air handling unit with double plate heat exchangers is installed in each house at Portvakten Söder. The efficiency of the heat recovery is as high as 85 percent and the SFPv of the fans is as low as 1.27 kW/m3/s.

Passive houses are well-insulated and extremely energy conserving, and for the most part, they are heated by internal heat generated by occupants and heat emitted from household appliances and machines in the flat. Passive houses make extremely high demands on air handling. IV Produkt was therefore contacted early in the project to secure an energy efficient solution for the passive houses.

Scandinavia’s largest expands

COPENHAGEN AIRPORT – Copenhagen, Denmark

airport with IV Produkt

Copenhagen Airport is situated southeast of the Copenhagen city centre and is the largest airport in Scandinavia with an annual average of over 20 million passengers.

In 2005 Copenhagen Airport was awarded the title The World’s Best Airport. During recent decades, the airport planners have invested in an ample enlargement of the entire airport area and terminals. A lot of people on the move means heavy demands on the air handling units. The units must be extremely reliable and adapt air volumes and temperatures in relation to the number of occupants. Through the last decade IV Produkt has been the main supplier of air handling units to the airport.

Flexomix IV Produkt is the main supplier of air handling units to Copenhagen Airport, especially thanks to the fact that IV Produkt was early on the scene with direct-driven fans and low sound levels. The latest project was the extension of shopping areas and safety zones with Flexomix air handling units of various sizes.

Fresh air and right temperature – puts people in a better shopping mood

Right temperature and good air quality are tremendously important factors for creating an attractive atmosphere where customers will enjoy shopping. MEDIAMARKT – Sweden

Flexomix with EcoCooler/StarCooler The great numbers of electrical apparatuses that are switched on all day long in the Mediamarkt stores require a sizable amount of air change and substantial cooling, which in turn means that an air handling unit with cooling energy recovery is needed. The solution was the Flexomix with an integrated EcoCooler cooling unit with cooling energy recovery.

A store filled with a vast selection of products is not everything – the right temperature and good air quality are tremendously important factors for creating an attractive atmosphere where customers will enjoy shopping. With hundreds of TV sets and other electronic products constantly switched on and emitting heat, the cooling load is enormous – 70W/ m2. IV Produkt offered a cost efficient solution of air handling units with integrated cooling.

St Petersburg Change is in the air

Aeroplaza is a modern office centre in St. Petersburg and is situated by the Pulkovo-2 Airport and the well-known Pulkovo-3 shopping centre. AEROPLAZA – St. Petersburg, Russia This high profile project in St. Petersburg is one of the new high-end commercial office centres being established near the international airports. Aeroplaza has large glazed surfaces that make high demands on maintaining the right air handling and temperature inside the building. The building has 33.330 square meters of floor space and an underground parking area with space for 175 automobiles.

Flexomix Air handling units with rotary heat exchangers guarantee good air quality and efficient heat recovery at Aeroplaza. Three of the air handling units are installed in the garage, and the warm extract air from the office floors of the building heat the garage to +10 C before the air is recycled. To save space, another three air handling units are mounted on the roof while the remaining units are installed in the  1.532 square meter plant room.

FlexoPool, Flexomix and Envistar Top With large volumes of water in motion and many activities such as the wave machine and bubble pools in use, Experium has a great need for ventilation and dehumidification in the facility. These premises are served by FlexoPool air handling units designed to operate in swimming pool facilities and other corrosive and aggressive environments. Other rooms are served by eight Flexomix air handling units, and nearby Experium Ski Star has also built a ski lodge where seven Envistar Top units are installed.

At Experium, which is open all year round, visitors can swim in one of Scandinavia’s grooviest adventure swimming facilities with Sweden’s first machine for indoor surfing. They can also go bowling, go to the cinema, enjoy spa treatment and eat food from every corner of the world.

Green Building high efficiency heat recovery

Flexomix To match the requirements of the Green Building concept, great efforts were made to achieve a solution with high heat recovery and low energy costs. Three Flexomix 3150 air handling units, IV Produkt’s biggest units with a heat recovery of 80 percent, are installed in the garage. The units are also equipped with free cooling since the need of cooling in the building is substantial. For maximum heat recovery, the warm air from the offices is used to heat the garage before it is used for preheating the supply air.

HAGAPORTEN 3 – Solna, Sweden

The building is owned by Skanska Fastigheter AB and was built as corporate headquarter for the Technical and Energy consultant company ÅF. The entire project was designed around low energy use to meet the Green Building EU Project standard. This means that this 28,000 square meter building consumes 25 percent less energy compared to the already high standard of the Swedish Board of Housing and Planning Regulations for New Construction (BBR).

We made choosing filters as easy as ABC. Wouldn’t it be great if all air filters were graded from A to G? That’s why we developed the Energy & Air Quality Rating. It should be easy to compare different filters. If a filter achieves a good grade it’s because it cuts energy costs and makes the air clean. It’s as simple as that.
