Liebert CRV - PD - 265086 - 11.01.2018
(*) The nominal heat rejection capacities refer to the following operative conditions:
•
refrigerant R410A
•
temperature differences: 15 K
•
(T condensation dew point - Toutdoor).
•
liquid sub-cooling 3K
•
height of the installation = 0 m, above the sea level.
•
for different conditions refer to New Hirating program.
•
clean exchange surfaces.
(**) The levels of sound pressure here included are measured in the same operative conditions, and are
referred to 5 m far from the unit, at 1.5 m in height, in free field conditions.
All air remote condensers are:
•
CE marked.
