FRESH AIR UNITS WITH ENERGY RECOVERY
Three versions in nine sizes with air ﬂows from 0.2 to 8.4 m3/s (700 to 30000 m3/h).
39SQ units are designed to supply fresh air to any type of building. The efﬁcient air-to-air heat exchanger recycles the heat from the exhaust air, pre-heats cold outdoor air in winter and pre-cools hot outdoor air in summer, resulting in impressive energy savings. High-efﬁciency units with counter-ﬂow plate (C models) or rotary heat exchangers (R models) with a thermal efﬁciency up to 85%. Casing performance (EN1886): air leakage L1, thermal transmittance T3, thermal bridging TB3. Standard-efﬁciency units with cross-ﬂow plate heat exchangers (P models) with a thermal efﬁciency up to 54%.
