The ESD 25 IP dehumidification and integration unit is equipped with an R134a refrigeration circuit for dehumidification of the ambient air and a finned coil which, if connected to the water system of the circuit of:

- radiant cooling (water 18/23 °C) allows to obtain a neutral air temperature at the unit outlet, when there is consent for dehumidification (compressor ON)

- cooling (water 7/12 °C) / heating (water 45/40 °C) allows integration to the heat output of the air conditioning/dehumidification system with the exclusion of consent to dehumidification

 

In particular, the following operating modes are possible:

- DEHUMIDIFICATION ONLY (without water): dehumidification using the cooling circuit only (without water integration)

- NEUTRAL AIR (with water integration 18-23 ° C): summer air treatment in combination with a radiant cooling system. The unit dehumidifies and treats the sucked air using both cold water from the radiant system and the internal refrigeration circuit. The outgoing air is neutral with respect to the incoming air

- AS A COOLING FANCOIL: summer air treatment, with the compressor off, the unit cools the sucked air using only the hydronic battery powered by cold water at the same temperature as the fan coils

- AS A HEATING FANCOIL: winter air treatment, with the compressor off the unit heats the air drawn in using the hydronic battery powered by hot water at the same temperature as the fan coils
