Brine Options (option 5B & option 6B)
Operating range with
45% ethylene glycol
Operating range with 45% ethylene glycol

Note: With options 5B & 6B the units are equipped with
traditional coils (Cu/Al).
The operating range is a function of the suction pressure,
which in turn is a function of:
-- The brine type
-- The brine concentration
-- The flow rate
-- The brine temperature
-- The condensing pressure (ambient temperature).

COOLING
This option allows production of brine down to 0°C (option
5B) / -15°C (option 6B). The unit is equipped with suction pipe
insulation (option 6B only) and a fan frequency converter.

Partial heat reclaim using desuperheaters
(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 30RBS range,
that are equipped with traditional Cu/Al coils.
A plate heat exchanger is installed in series with the air
condenser coils on the compressor discharge line of each
circuit.
