Public buildings, offices, stores, schools, restaurants.

High efficient heat recovery units up to 88% with rotary wheel, plug-fans with backward curved blades and EC external-rotor motor. Preconfigured 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 (RAL 7024) with a high resistance against corrosion (class: RC3) and UV light (class: RUV3) according to EN 10169 and the inner skin is made from galvanized 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, 10000 and 15000.

Consult technical literature for performance values.

Versions available:

• Horizontal discharge HD.
• Vertical discharge VD.
• Sizes: 700 m³/ hour,1300 m³/ hour, 1900 m³/ hour, 2500 m³/ hour, 3.500 m³/ hour, 4500 m³/ hour, 6000 m³/ hour, 8000 m³/ hour, 10000 m³/ hour and 15000 m³/ hour.

Fan/ Motors:

Plug-fan with backward curved blades, external rotor EC motor with maintenance free ball bearings and permanent lubrication, with integrated electronic protection (locked-rotor, phase failure, under-voltage, over-temperature, short-circuit). Protection IP54, Class B. (RHE-8000/10000/15000 models, Class F)

Models:

• RHE D: without additional heater.
• RHE DI: with built-in electric post-heating.
• RHE DC: with built-in hot water coil.
• RHE DFR: with two-row coil built-in reversible hot/chilled water integrated (the cold water version coil only for the models HD).
• RHE DFR4R: with four-row coil built-in reversible hot/chilled water integrated (for models 6000, 8000, 10000 and 15000).
• RHE DC/DF: with 2 independent integrated coils (chilled water and hot water).
• RHE DX: direct expansion integrated coil (only for horizontal discharge, HD versions, except 15000 model). 

Control (Plug & 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 two working points. The fans are controlled separately.
• COP - constant pressure Constant pressure measured by an external sensor (accessory).
