18 - PARTIAL HEAT RECLAIM USING DESUPER-HEATERS (OPTION 49)
This option permits the production of free hot water using heat reclaim by desuperheating the compressor discharge gases. The option
is available for the whole 30RQS/30RQSY range.
A plate heat exchanger is installed in series with the air condenser coils on the compressor discharge line of each circuit.
The control configuration for the desuperheater option is factory assembled.
