Chillers and heat pumps for outdoor condensed
in the air with R410A Series NRL have been de-
signed and manufactured to satisfy heating and
cooling needs and the production of domestic
hot water (DHW) in medium to small commercial
or residential buildings.
Maximum reliability
The presence of several scroll compressors allows
NRL chillers various partialisations of the cooling
capacity.
Models:
1. NRL "°" standard chiller
2. NRL "H" heat pump *
3. NRL "C" motocondensing
The versions can be in different set-ups at the
same time in order to satisfy a wide range of
plant engineering solutions:
1. "A" HIGH EFFICIENCY
2. "E" SILENCED HIGH EFFICIENCY
3. "D" WITH DESUPERHEATER
4. "T" WITH TOTAL RECOVERY
Configurations not allowed:
YD / YT / YH
HT / HC
TC / DC
* Possibility of production of D.H.W.
(DCPX_UL | VMF-ACS | AER485).
