High efficiency HRU


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.

In accordance with the new EU 1253/2014 norm, they are equipped with a high efficiency counterow plate heat recovery unit (in dry conditions, superior to the minimum efficiency prescribed by the law of 67%), with ­ lters with extremely low pressure drops (F7 on fresh air and M5 on room air exhaust, e ciency calculated according to EN 779:2012) and with backward-curved blades fans, directly coupled with EC motors, guaranteeing power absorptions well below the limits indicated by the norm.
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 both vertical and horizontal con­figuration and in 7 sizes with performances ranking from 450 to max 5.500 m3/h.


• The casing is made with double skin panels, with 25mm thick rockwool insulation with ­ re reaction class A2S1d0; 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 ­ lters sections is ensured by doors with hinges and locking devices; additional access is given to the ­ lters thanks to lift-o– panels.
• The units are complete with an electronic control device for the setting of the ventilation and temperature, monitoring of the status of the ­ lters, week programming, defrost management and anti-freeze device for the additional water coil module.
