** Standard unit (with MCHX coils) and desuperheater option
*** Unit with option 15 + desuperheater
**** Unit with option 15 + desuperheater + hydronic module with high-pressure dual pump
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 30RB range.
A plate heat exchanger is installed in series with the air con-
denser coils on the compressor discharge line of each circuit.
The control configuration for the desuperheater option is
factory assembled (see chapter 11.3.6 - Control configura-
tion).
