Specifications
Typeical benefits and advantages:
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.
Usage:
Productsare suitable for R134A, R22, R404A, R407C, and CO2 refrigerant.
Widely used for commercial refrigerators and freezers, commercial showcase cabinet,air-conditioning systems, dehumidifier, ice maker etc.
