Heat recovery unit
The units of the ERSR series are designed to satisfy the temperature and humidity comfort and ventilation requirements typical for public areas. The units are characterised by a high effi ciency low pressure drop rotary heat exchanger (with the option of having a hygroscopic treatment on its surfaces). The heat recovered by this exchanger ensures the contribution from the air conditioning system is kept to a minimum: in this way a highly cost effective operation is achieved. Signifi cant economic savings are ensured also by the use of plug fans with electronically controlled motors (up to size 17) or with high effi ciency inverter controlled motors. The unit is “plug & play”, being supplied with an electronic controller and unit mounted electrical power panel. The special control software is capable of maximising the use of the unit in energetically favourable conditions.
