EQRS – the complete rotor This brochure describes EQRS, a new addition to Fläkt Woods’ range of rotary heat exchangers. Our hygroscopic rotor has been specially developed for operation in contaminated air flows. The rotor medium is coated with a highly effective transfer media (3 Angstrom molecular sieve) that almost completely eliminates the transfer of contaminated air. Only 0.04 % of contaminated air by volume is transferred. This means that the rotary heat exchanger does not spread any contaminants or odours. The high cooling efficiency saves energy, improves the quality of the indoor...

EQRS – a very powerful heat exchanger EQRS is a very powerful rotary heat exchanger that recovers both sensible (heat) and latent (moisture) energy, and does so considerably more fficiently e than other rotors on the market. With an efficiency of up to 85 %, EQRS is one of the most powerful rotors available on the market today. EQRS can also maintain equally high sensible and latent efficiencies under harsh operating conditions. It achieves this thanks to a unique transfer core in the winding of the rotor. The cells are created using an aluminium substrate that is coated with a fastacting...

Compact design Another important reason for using a 3A molecular sieve is the ability to achieve higher performance at high air flow rates, which results in a more compact rotor design for a given air flow rate. Labyrinth seal EQRS uses a labyrinth gasket that has been designed to give the optimum performance at a given pressure drop. Because the seal never touches the rotating surface it has an unlimited life. The sealing area is easy to adjust. This effective sealing system increases performance and practically eliminates the transfer of contaminants from the extract air to the supply...

High efficiency in winter Sturdy construction During the cooling season outdoor air is cooled and dehumidified by the rotor. This reduces cooling requirements considerably. During the heating season the process is reversed and outdoor air is humidified and heated as the rotor spins. The ability of EQRS to recover both sensible and latent energy means that the rotor also performs better under winter conditions. The reduced risk of icing enables the rotor to recycle a larger proportion of the extract air and hence reduce the power demand of the heating coil. EQRS improves energy savings all...

Twin Wheel – effective moisture regulation Designed to allow simple bearing replacement The bearings used in EQRS units have a long life and require minimal maintenance. The external bearing blocks simplify any bearing replacement if this should ever be necessary. The rotor remains in its casing and no part of the rotor or support structure needs to be removed or dismantled. Twin Wheel is a successful system from Fläkt Woods that is intended primarily for use in applications where moisture regulation is essential. The technology is based on two rotary heat exchangers and a cooling coil. In...
