Brine Options (option 5B & option 6B) Operating range with 45% ethylene glycol Operating range with 45% ethylene glycol 55 45 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). 35 Outside air temperature, °C Outside air temperature, °C 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. 25 15 5 -5 -15 -25 -20 -15 -10 -5 0 5 10 Evaporator leaving water temperature, °C Evaporator leaving water temperature, °C Option 5B Option 6B Option 5B Option 6B 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.
