DEHUMIDIFICATION bigger which can impact on space and capital costs. In addition, many commonly available units may not be the best solution for allyear-round heating and some still use gases soon to be phased out due to Global Warming Potential. To help customers make the correct choice of system, Recotherm have qualified, time served surveyors, designers and f-gas engineers in-house. The air to water systems are usually independent of their air handling units and dealt with by contractors, but they have experienced team members able to support customers with impartial advice on projects. The company provide a full design, service and aftersales support package from qualified staff for all the air to air projects.

energy is recycled and upgraded through the heat pump system and provides greater amounts of sensible heat energy back in to the swimming pool water or pool hall air. Efficiencies in excess of 380% are achievable albeit from the same source, meaning the Phoenix EC out performs many current alternative methods of energy recycling on the market today.

CALOREX’S DELTA TAKES CONTROL Designed and engineered in the UK, the Calorex Delta is a unique multi-functional single unit which features touch screen technology as standard. It is the ultimate environmental control system, designed to take full control of the whole indoor environment and pool water heating. A comprehensive range, there’s a Delta to suit pools of every size. The system is specifically designed to provide the environmental comfort and moisture-related structural protection necessary for a pool in the most efficient way. Totally self-contained, the Delta will remove moisture and recover energy which is then re-used to heat the pool water and air. By utilising this method of heat recovery, energy costs are kept to a minimum. Typically, for every unit of power that a Calorex heat pump consumes, it will convert 2.4 times this amount to usable heat. The potential energy savings are huge. In fact, compared to traditional heating and ventilation methods, cost savings of over 50% are achievable while corresponding CO2 emissions can be dramatically reduced by as much as 70%. The Calorex Delta 14 and 16 benefit from ECA Scheme Approval meaning they are recognised as being able to provide low carbon and energy efficient environmental control. They are the only swimming pool heat pump heat recovery machines to be included in the Government Cash Back Scheme.

TROTEC’S GERMAN QUALITY AND INNOVATION IS AVAILABLE FROM FAIRLOCKS

Recotherm has recently developed their Aerum systems that provide fresh air dehumidification combined with air to air heat via Toshiba heat pumps

RECOTHERM PROVIDE A BREATH OF FRESH AIR TO INDOOR PROJECTS The use of air source heat pumps to heat the water in external pools is well established but many of these are not suitable for indoor pools and installers need to be aware of the pitfalls such as low operating ambient limits and instead go for high quality, performance systems for both air to water and air to air. Many of Recotherm’s domestic units are designed around heat pumps providing the low pressure, hot water (LPHW) and the company has also recently developed their Aerum systems that provide fresh air dehumidification combined with air to air heat via Toshiba heat pumps – ideal where additional LPHW plant is not needed or desired. With Aerum, all the features normally associated with the Recotherm Aeris range (high build quality, state-of-the-art controls, pleasant fresh air environment in the pool hall and technical backup) are still there, but with the added advantage that the unit is a standalone package and can provide a significant amount of cooling in the summer if this is required. Heat Pumps may be a necessity in future and they can be a benefit if owners want to reduce their impact on the environment, but they do operate at lower temperatures in a high temperature environment so heat exchangers and ductwork generally need to be

The DS series of dehumidifiers from Trotec feature highly efficient moisture control and heat recovery for all indoor pools and spas. They are now in stock and available from Fairlocks Pool Products. Made in Germany, the professional quality DS 30 and DS 60 models have been specifically developed for swimming pool hall dehumidification. Incorporated into the design of both dehumidifiers is a fibreglassreinforced, easy-to-clean plastic housing. Inside each unit, quiet running and powerful radial fans ensure high air circulation rates, while insulated compressors and polyestercoated heat exchanger surfaces provide protection against corrosion. Both wall-mounted units are easy to install, work fully automatically and can extract large amounts of moisture from the room air, even in air temperatures as low as 5°C. The energy absorbed during the process of dehumidification is turned into warmth and directly used for heating the room, which further increases the device’s efficiency. As an example, for every unit of electricity that the units consume they will give 2.5kW of heat back to the room.
