Baltimore Aircoil International (BAC) VXC S455

BAC VXC S455 evaporative condenser, 2015, R134a, s/n H150832701 — chiller heat rejection.

Used 6 units Baltimore Aircoil International (BAC) VXC S455 evaporative condenser, built 2015, serial number H150832701. Made in Heist-op-den-Berg, Belgium.
It is an evaporative condenser: hot refrigerant vapour enters the coils inside the unit, water is sprayed over the coil surface, and centrifugal fans draw air through the pack. The refrigerant condenses and returns to the refrigeration plant. No separate water-cooled condenser is required on the chiller.
The unit has twin R134a heat-exchanger coils (circuits A and B) and a centrifugal fan section. It was installed on a rooftop as the heat-rejection side of a refrigeration / chilled-water plant.
