REFRIGERANT COMPONENTs
- Filter with molecular sieve and activated alumina;
- Sight glass with humidity indication;
- Thermostatic valve with MOP function and external
equalisation;
- Electronic expansion valve for insuperable performances in
middle and winter season: the pay back of this solution in
northern Europe countries is less than 1 Year;
- Liquid receiver according CEE 97/23 PED directive;
- HP pressostat with manual reset according cat. IV CEE 97/23
PED;
- LP pressostat with automatic reset and delayed time during
start up;
- Schrader valves for maintenance and or controls.
REFRIGERANT PIPEs CHARACTERIsTICs
On site piping has to be done by
professional and trained
technicians only.
Use only "CUB" quality copper pipes. Take
care when using nitrogen during all brazing operations in order
to avoid humidity and dirt inside the pipes.
rEFrIGErATION CIrCUIT
DEHUMIDIFICATION PHAsE
During the dehumidification phase all DX units [optional] operate
with a reduced heat exchanger surface in order to decrease the
evaporating temperature and as a consequence to increase the
latent percentage
