1 Use Improve heat exchanges with high-efficiency tubes Quality refrigerating components ange of optimised devices Cooling capacity : 100 to 2000 kw This generation of shell and tubes evaporator has been designed for integration into high and medium power cooling systems. Description FYC - UYC To be used with all halogenised, zeotrope or azeotrope refrigerant fluids (507, 134a, 404A, 407C...). The bundle tubes are of copper. Description U YC V2 2V2 : Number of balanced refrigerant circuits : Type of WATE circuit baffles 2 : Number of refrigerating circuit passes : Type of bundle filling 27 : Length of the bundle in dm 406 : Diameter of the casing in mm YC : Denotes the COEVA range of evaporators U : Type of bundle.
