Screw Chiller Part Shell And Tube Heat Exchanger Water Cooled Evaporator
Screw Chiller Part Shell And Tube Heat Exchanger Water Cooled Evaporator
Shell and tube type cold water machine evaporator due to the heat transfer effect is good, the structure is compact, cover an area of an area small, easy to install, so the application is very extensive.Shell and tube type cold water machine evaporator structure and horizontal shell and tube condenser, the same.Appropriate velocity control, load the refrigerant from the lower end cover, from the upper, and flows back and forth in the YanFa tube and end cover, become more program flow.
our self-developed products include dry type spiral baffle plate evaporator, flooded evaporator, built-in oil separator condenser, sea water condenser, stainless steel heat exchanger, oil cooler, oil separator, gas-liquid separator and liquid accumulator among others. The spiral baffle plate evaporator is the latest product designed and made by Qiaoxin and has obtained the national technical patents, which can save 20% in copper consumption and 30% in ferrous metals, reach the total energy saving rate 30% after test and satisfy the national economic policy of industrial upgrading, saving energy and reducing consumption and environmental protection. 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.
