Use double-wall finned copper heat transfer tube,can be used in drinking water of cooling/heating. - details see: https://www.machineto.com/double-wall-tube-potable-water-heat-exchanger-heat-transfer-equipment-copper-coil-heat-exchanger-10241979

Work Condition:
1)Refrigerant side(Between the tube and shell):R22,R134a,R407c,R410a
2)Water side (in the tube):Nature water,sea water,antifreeze(glycol water)

Material
1)Heat transfer Tube: double-wall copper tube.

2)shell: High quality steel.

Features:
1)capacity:24000BTU(7KW)

2)Small volumeCompact size is helpful to save the space ,Thereby reducing the size of heat pump.
3)It can be used in drinking water of cooling/heating,dairy/beverage heating/cooling,chemistry,chemical engineering,bio-food,medicine and other special industries cooling/heating heat exchanger.

High Effciency of Heat Exchange
1)Using high efficiency rifle tube, heat exchange area is 3.6 times than the Smooth Tube.
2)Fins inside and outside of tubes induce turbulence flow of freon and water,it's one cause of high efficiency.
3)The compact helix structure of the coil ensures sufficient heat exchange between the gas and water.

Safety:
1)Double-wall copper tube to prevent leakage in the heat exchanger used for participating in the two kinds of heat exchange media,cross-contamination doesn't occur.Improved heat exchange of security and reliability.

2)The Copper Tube is fully shaped and then installed into the shell thus free from Products processing defects.
3)There is not block on water loop and the water flow is smooth,thus keep it free from ice and dirty.
4)The water pipe is on the lowest position ,and easy for drainage in cold season.

Structure;

1) Type A,accumulator included. when there is accumlator included,the gas pressure of the heat pump can be reduce obviously,thus enhance the heat exchanger.

2)Type A is suitable for condenser .
