GCU-25 : External cooling unit 2.3-4.5 kW (for splited cooling systems)

The cooling condenser unit intended for the cooling of the water (usually with glycol solution) in the industrial cooling water tank (ICWT – industrial cooling water tank is not included in this set and it must be purchased individually according to requirements of the customer). The iced water is then used to cooling of the beverage production tanks like fermenters or beer storage tanks and also to cooling other devices in the brewery. This equipment uses a special technical coolant intended to chilling systems that has to be filled and pressurized into the primary circuit only by qualified person. This equipment uses ice water or glycol as coolant. The cooling unit is compatible with all types of ICWT cooling water tanks of our production. The output copper pipes of the condenser cooling unit has to be joined with input copper pipes of the pipe heat exchanger or the primary side of the plate heat exchanger of the ICWT cooling water tank. Cooling capacity 2300 W – 4500 W.
