HRH. High efficiency heat recovery units. from 300 to m³/h >70 % WITH HIGH EFFICIENCY HEAT RECOUPERATOR

Transcription

1 4 Lmf Clima 6 HRH High efficiency heat recovery units WITH HIGH EFFICIENCY HEAT RECOUPERATOR from 3 to 4.3 m³/h The HRH units have been designed for non-residential applications for which a forced and mechanical air changeover is requested. In accordance with the new EU 3/4 norm, they are equipped with a high efficiency counter-flow plate heat recovery unit (in conditions, superior to the minimum efficiency prescribed by the law of 67%), with filters with extremely low pressure drops (F7 on fresh air and M on room air exhaust, efficiency calculated according to EN 779:) and with backward-curved blades fans, directly coupled with EC motors, guaranteeing power absorptions well below the limits indicated by the norm. The casing is made with double skin panels, with mm thick rockwool insulation with fire reaction class ASd; external panels are in prepainted steel, internal panels in galvanized steel. Integrated by-pass system with actuator, for free-cooling operations. Access to fans and filters sections is ensured by doors with hinges and locking devices; additional access is given to the filters thanks to lift-off panels. The units are complete with an electronic control box for the setting of the ventilation and temperature, monitoring of the status of the filters, week programming, defrost management and anti-freeze device for the additional water coil module. >7 % EU 3-4 COMPLIANT PLUG&PLAY EC FANS EFFICIENCY HORIZONTAL ORIENTATION VERTICAL ORIENTATION
