China good quality direct expansion evaporator coils

China good quality direct expansion evaporator coils

Direct Expansion Evaporator coils are engineered and designed to deliver maximum heat transfer efficiency under a wide range of operating conditions. We can offer a wide variety of circuiting coils, including interlaced Row/Face split, to meet the performance requirements of various applications. Evaporator coils are counter flow circuited and have optimized size suction headers and refrigerant distributors. The distributor tubes are of equal lengths to ensure equal distribution of refrigerant into each circuit.

Our factory located in Hangzhou, China,10 minutes car distance to our office.
Our factory is ISO 9001 certified, professional in production of copper tubefin evaporator and condenser.
We use high quality material, equipped by high automation machinery like finpunching machine, auto tube flaring machine, automatic welding machine, we haveover 15 years experience in production and with professional technicians tocontrol mold production, IQC, IPQC, FQC and OQC, all products comply with Japan& Italy standard, all these make us achieve good sales increasing year byyear and awarded nice quality reputation among all customers.

• Well distributed liquid dispensing of windward area ofcondenser coil

• High quality mechanical expanding or super high pressinghydraulic expanding between copper tube and fins, tight contacting andoptimized heat exchanging.

• Free pitch distance selection, reduce the frost affection inlow temperature.

• With single or double reverse-flow system, small waterresistance, good heat exchanging

• With super high temperature vacuum drying, ensure innerwithout impurity or water substance.
