REC PRO 9S High efficiency Heat Recovery Units Non residential applications EFFICIENCY 9% Comply with ErP Directive 125/29/CE and EU Regulation 1253/214. Classification: Non Residential Ventilation Unit (NRVU). Bidirectional Ventilation Unit (BVU). DESCRIPTION The heat recovery units of the REC PRO 75 series are designed to match the need to equip the buildings with ventilation systems which can combine low energy consumption, high aeraulic performance and high indoor air quality. They can easily be integrated with conventional heating and air-conditioning systems and their construction is optimized for a ducted installation in false ceilings and for an all-seasons operation. The series is available in 4 sizes with performances ranking from 4. to max 23.5 m 3 /h. 4 sizes Airflow from 4. to 23.5 m 3 /h Very high efficiency static heat exchanger CONSTRUCTION Supporting structure in extruded aluminium profiles Curtain panels 42 mm thick of sandwich type with special sealing gaskets; exterior finish RAL 92 and thermal acoustic mineral wool insulation class and high density. Filtering sections of F7 efficiency class with soft bags on the outside air circuit and M5 on exhaust air circuit, removable from the side. Fan sections with single inlet backward-curved blades plug-fans directly coupled to EC brushless motors. Very high efficiency (>9%) counterflow heat recovery, aluminium heat exchanger plates with supplementary sealing and built-in motorized by-pass device. Complete control panel with remote display and microprocessor for temperature control at fixed air flow, based on the operation logics designed to maximize energy savings and environmental comfort, thanks to the modulation of air flow guaranteed by the inverter technology. The unit is designer for RS485 connection to supervision systems based on Modbus RTU protocol. UPON REQUEST REC 9S can be supplied with the following function components, assembled and connected, to be requested in stage of order: PSTD - Filters differential pressure switch. DPS - Differential pressure sensor. AQS - Ductable CO 2 probe. RANGE CODE MODEL 1RC92 REC PRO 9 S 4. 1RC921 REC PRO 9 S 7.7 1RC922 REC PRO 9 S 11. 1RC923 REC PRO 9 S 13.2
