Double flow heat pump: FR CH RE V

Description

Double flow heat pump with 20-year anti-corrosion guarantee

The FR CH RE V is the perfect ventilation and air conditioning solution for cinemas or entertainment halls. It offers maximum air quality while ensuring acoustic comfort. This vertical double flow heat pump is delivered ready to operate and can be installed either on a rooftop or at ground level, depending on your needs. Thanks to its full aluminium structure (frame & casing), this unit is covered by a20-year guarantee against corrosion.

The FR CH RE V operates as a reversible heat pump:

• Source: outside air + inside air (in recovery mode)
• Treated fluid: inside air + hygienic fresh air

The unit offers several operating modes:

• Heat pump
• Cooling
• Free Cooling: cooling with outside air, without thermodynamics

In these modes, the unit can operate:

1. With all recirculated air
2. With all fresh air/all exhaust air
3. With mixed-air

The unit ensures air exhaust and fresh air modulation without indoor pressure change.

The ETT packaged unit comprises 3 different sections:

1. The separate technical section houses the refrigeration components, the electrical board and the control components.
2. The internal section ensures air change and air treatment.
3. The exhaust air section allows heat recovery and/or removal on exhaust air (depending on the operating mode).
