Double flow heat pump: EFFI+ RE
The EFFI+ RE double flow heat pump is specially designed for ventilation, heating and air conditioning in buildings with variable occupancy, such as cinemas, entertainment halls and community halls. This self-contained unit features specific components to maximise energy savings.
As an ErP 2018 ready unit, the EFFI+ RE meets the European regulatory obligations as per Directive 2009/125/EC on the ecodesign of ErPs (Energy related Products).
Description
Double flow rooftop heat pump & air conditioner with rotary heat exchanger covered by a 20-year anti-corrosion guarantee
The ETT packaged unit is delivered ready to operate. Its full aluminium structure (frame & casing) ensures an excellent corrosion protection (20-year anti-corrosion guarantee).
The ETT unit can be installed either at ground level or on a roof. ECODESIGN involves DECONSTRUCTION: ETT units are 98% recyclable (re-use and recycling rates based on ULTI+ 21)
The EFFI+ RE heat pump with heat exchanger operates as a reversible heat pump:
- Source: outside air + exhaust air (in recovery mode)
- Treated fluid: outside air + hygienic fresh air
The unit offers several operating modes:
- Heat pump
- Cooling
- Free Cooling: cooling with outside air, without thermodynamics
- Recirculation
The EFFI+ RE offers several operating modes:
The ETT packaged unit comprises 4 different 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 heat recovery and/or removal on exhaust air (depending on the operating mode).
- The rotary heat exchanger section allows heat recovery.
