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.

Note:
Pressure drop, clean filter = 6 Pa
Pressure drop, dirty filter = 12 Pa
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.
