China Starch Sweeteners Equipment Tubular Heat Exchanger

Description
Stainless steel shell tube type water cooled dry evaporator
Stainless steel shell tube type water cooled dry evaporator 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 ºC cold agent.
(2) 304/316 l stainless steel tube, it is mainly used for food and low temperature (below 25 ºC, higher than 40 ºC) of the refrigerant, 316 l can also be used for cooling load of the sulfate for industry.

3, interface:
(1) load cooling interface main type of flange, thread and clamp type, as shown in figure. According to the demand of users.
(2) the refrigerant interface are mainly brass brazing type, loose flange connection type and tenon surface flange connection type, etc. As shown in figure. Can meet the requirements of users and habits to the greatest extent.
(3) the upper shell put empty set, lower set drainage outlet. Nozzle temperature is set on the mouth. Also can according to user requirements including water flow switch interface, antifreeze switch interface. Temperature measurement are mainly female mouth mouth and various rules of blind brass like ∅ 5/16, "3/8", 1/2 "∅ ∅, ∅ 5/8" brass or stainless steel tube, etc.
