High efficient heat recovery units up to 88% with rotary wheel, plug-fans with backward curved blades and EC external-rotor motor.
Pre-configured control system for easy start-up.
The casing is made of 50 mm, self-supporting double skinned panels (mineral wool, 40 kg/m3, thermal conductivity 0.037 W/ mK). The outer skin is made from coated steel (RAL7024) with a high resistance against corrosion (class: RC3) and UV light (class: RUV3) according to EN 10169 and the inner skin is made from galvanised steel.
Support feet are made from 3 mm, RAL9011 coated, 100 mm height (except RHE 6000 to 10000 models, which are base-mounted), with possibility to fit anti-vibration mounts or leveling feet (as accessories).
Easy access to all components via large hinged front doors.
Circular inlet and discharge connection flanges with EPDM rubber seal strip, VELODUCT© tightness class D up to size 3500 HD, rectangular connections for the sizes 4500 VD, 6000, 8000 and 10000.

Fan / Motor
Plug-fan with backward curved blades, external rotor EC motor with maintenance free ball bearings and permanent lubrication, with integrated electronic protection (lockedrotor, phase failure, under-voltage, overtemperature, short-circuit).
Protection IP54, Class B.
(RHE-8000 and 10000 models, Class F)

Application
Public buildings, offices, stores, schools, restaurants.

Control (Pulg&Play):
VAV- variable air volume
Fan speed can be adjusted with a 0 – 10V signal from the remote touchscreen panel (included) or an external CO2, temperature or humidity sensor (accessories).
CAV – constant air volume
Manual pre-setting of 2 working points. The fans are controlled separately.
COP – constant pressure
Constant pressure measured by an external sensor (accessory).
