Reversible heat pump with 20-year anti-corrosion guarantee
FR CH RR / HPE+ CEE heat pump offers fully optimised air treatment.
Thanks to its full aluminium structure (frame & casing) which ensures an excellent corrosion protection, this air conditioning and heating system is covered by a 20-year anti-corrosion guarantee.
This single flow rooftop heat pump is delivered ready to operate. A separate technical section facilitates service and control of the unit and allows measurement and adjustment during operation.
This air handling unit operates as a reversible heat pump
- Source: outside air + internal air (in recovery mode)
- Treated fluid: internal air + hygienic air
Operating modes can be:
- Heat pump
- Air conditioner
- Free cooling: cooling with outside air, without thermodynamics
In those cases, the double flow heat pump operates:
- In all recycling mode
- In all fresh air / all exhaust air
- In mixing mode
FR CH RE / HPE + RL double flow heat pump ensures air extraction and fresh air modulation while maintaining a constant indoor pressure.
The ETT packaged unit comprises 3 separate sections:
- The separate technical section houses the refrigeration components, the electrical board and the control components.
- The internal section ensures air change and air treatment.
- The exhaust air section allows exhaust air calories recovery and/or removal (depending on the operating mode).
