Copper Coil in shell Heat Exchanger,Various BTU and RT (Ton Of Refrigeration)

The heat exchange copper coil is in spiral distribution and with compact structure. For small gap of refrigerant passage, this can ensure effectiveness of heat exchanging, and prevent lubricant accumulation.The sprial copper coil can increases the heat exchanging area, improve the liquid wettability and distribution, thus effectively decrease water film and improve heat-exchange efficiency.


1.High efficiency finned tube,3.7 times than smooth tube
2.Small flow rate, big temp. difference
3.Best choice for heat pump.

Work Condition:
1)Refrigerant side (Between the tube and shell):R22,R134a,R404a,R407c,R410a,R600a,etc.
2)Water side (inside of the tube):Domestic water,tap water,antifreeze (glycol solution)
3)This structure A suitable for used as condenser,For heat mode.

Material to adopt:
1)Heat transfer Coil Tube:High efficiency finned copper tube coil,(Optional: finned nickel-copper tube , finned double-wall copper tube)
2)shell: High quality soecial steel used in compressor ,thickness:4mm.

1)Thanks to the small flow rate, big temperature difference design,easy to get the high-efficiency heat transfer ability.
2)Small volume Compactly design is helpful to save the space ,Thereby reducing the size of whole units.
3)It’s widely used in air-source heat pump, water-source heat pump and refrigeration units.
4),Various refrigeration loading capacity,different BTU and RT (Ton Of Refrigeration)

High Effciency of Heat Exchange:
1)Use efficiency finned copper tube, heat exchange area is 3.7 times than the Smooth Tube,it is a important cause of high efficiency.
2)Inside the tube is screw thread,so the water will eddy flow forward ,it’s another cause of high efficiency.
3)The compact helix structure of the coil ensures sufficient heat exchange between the gas and water.

1)Whole tube inside shell has no internal joint,that means no welding bug.
2)The Copper Tube is fully shaped and then installed into the shell thus free from Products processing defects.
3)There is no block on water loop and the water flow is smooth,thus keep it avoid dirty.
4)The water pipe is on the lowest position ,and easy for drainage in cold season,avoid freeze.


*With single water pipe


* With double water pipe


* Inner design with copper coil.
