Double System Shell and Tube
Dry Type Water - Cooled Heat Exchanger
Double System Shell and Tube Dry Type Water - Cooled Heat Exchanger is suitable for water cooled
unit, water source heat pump, air cooled pump and air cooled heat pump unit.
The product is applying for refrigerants of R22, R134a, R407C and R410A etc.
The referigerating medium is for tap water, underground water, river water and sea water or brine, water
and glycol solution, sulfate solution, etc.
For heat exchange tube, copper pipe, copper nickel alloy tube, aluminum brass tube, stainless steel tube,
etc.
The shell raw material mainly are seamless steel tube, stainless steel pipe.
1, Heat exchange tube: four main tube type.
(1) ∅ within 3/8 "thread copper coil, it is mainly used for" U "type tube evaporator.
(2) ∅ within 1/2 "threaded straight copper tube, straight tube is mainly used for dry-type evaporator.
(3) ∅ 1/2 "corrugated straight stainless steel tube, straight tube is mainly used in food industry of dry
evaporator.
(4) ∅ 5/8 "inside outside screw wing efficient copper tube, it is mainly used for air precooling industry dry
evaporator.
2, shell raw material:
There are two of the major materials:
(1) # 20 seamless steel tube, mainly used for all kinds of load - more than 20 ℃ cold agent.
(2) 304/316 l stainless steel tube, it is mainly used for food and low temperature (below 25 ℃, higher than
40 ℃) of the refrigerant, 316 l can also be used for cooling load of the sulfate for industry.
