• One unit for the production of hot and cold water, instead of the combination of chiller + boiler

– Note: The use of a heat recovery units of not polyvalent type, can produce hot water ONLY if cold water is also required, also the number of compressors in operation is determined only by the cooling load. It’s different with NRP

• Reduction of technical spaces• Simplification of the hydronic system and thermoregulation • Reduced maintenance• Energy savings• Cost reduction

Modular Layout:

it is possible to install many units in parallel connection

3” Isolating valves

10” Isolating valves

By using true parallel unit connectionthe entire chiller plant does not needto be stopped to isolate a unit in case

of a break. Isolating valves allowto pull a unit out of the array while the

whole system continues to operate

The same procedure is impossible with connection in parallel used by

other manufacturers

SILENCE & COMFORT

AERMEC Inverter Fan Coils

Comfort: much higher precision in a constant ambient temperature

Acoustic Comfort: The speed change is continuous

and not acoustically noticeable.

At a 22,5 dB(A) the AERMEC fan coils emit lower noise

than a dB level at a whisper only library (30 dB(A)).
