NEROSWIM +

Dehumidifier

The NEROSWIM + is a dehumidification unit that uses modulated fresh air. The pool hall is heated by a hot water coil combined with heat recovery coils. The heat recovery coils perform an initial heat recovery without any external input, resulting in significant energy savings.

On the discharge side, two evaporators recover heat from the air coming from the swimming pool. The refrigeration circuit recovers this energy to heat the water in the pools or to pre-heat domestic hot water.

Performance (according to EN 14511 standard)

Flow range: 10,000 – 60,000 m3/h

Cooling capacity range: 50 - 300 Kw
