Product Description NTF Hot Gas Regulator     General  NTF capacity regulatorsadapt compressor capacity to actual evaporator load. NTF was installed in a bypass line betweenthe low and high pressure sides of the refrigeration system, for hot gas injection between the evaporatorand thermostatic expansion valve. Injection shouldbe arranged to occur througha liquid-gas mixer.   Characteristics Superior control accuracy Direct connection to system suction line regulates hot gas injection independent of evaporator pressure drop. The NTF increase evaporator gas velocity, thus ensuring better oil return to compressor. Protection against too low an evaporating temperature, i.e. prevents evaporator icing. Can be used for HCFC and HFC. Max. working pressure 36 bar. Regulating range 0-8bar, Factory setting 0.4 bar. Temperature of medium -50℃~+140℃. Environmental temperature -40℃~+55℃. Any special requirement, please contact STF. Technical data   Capacity Regulator
