Tube Heat Exchanger Stainless Steel Water
Cooling Evaporator for refrigeration unit
Tube Heat Exchanger Stainless Steel Water Cooling Evaporator for
refrigeration unit 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.
3, interface:
The heat exchange tube uses copper pipe, nickel-copper alloy tubes, aluminum brass tube and stainless
steel tube as the material and the shell uses No.20 seamless steel tube and stainless steel tube.
