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.

The versions can be in different set-ups at the same
time in order to satisfy a wide range of plant enginee-
ring solutions:
1. "A" HIGH EFFICIENCY
2. "E" SILENCED HIGH EFFICIENCY
3. "D" WITH DESUPERHEATER
4. "T" WITH TOTAL RECOVERY
Configurations not allowed:
