Single flow heat pump with 20-year anti-corrosion guarantee
The CTA CH / 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. The separate technical section facilitates service and control of the unit and allows measurement and adjustment during operation.
The following operating modes are available:
- Heating
- Cooling
- Free Cooling: cooling with outside air, without thermodynamics
In those cases, the CTA CH / HPE+ CEE unit can operate:
- With all recirculated air
- With all fresh air
- With mixed-air
The ETT packaged unit consists of 2 separate sections:
- The separate technical section houses the hydraulic components, the electrical board and the control components.
- The internal section ensures the air change and air treatment.
