FRESH AIR UNITS WITH ENERGY RECOVERY 39SQC/R/P AIR TREATMENT 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%. 728 C A R R I E R 2 0 1 6 / 2 0 1 7
