Copper Tube Aluminum Fin Heat Exchangers
Evaporator and condenser coils made from inner-grooved copper tube and aluminum fin. We build to your drawing, and every coil is leak-tested at 3.8 MPa before it is packed.
- TP2M inner-grooved copper tube. The grooves increase the inside surface and improve heat transfer.
- 8011-H24 aluminum fin: hydrophilic (blue), bare, or with an anti-corrosion coating.
- Works as an evaporator or a condenser.
- Connections: threaded, brazed, or V-groove.
- Suitable for R513A, R134a, R404A, R407C, R410A and R290.
- Tube pattern, circuits, fin pitch and size follow your drawing or your duty requirements.

How it is built
A coil is a stack of stamped aluminum fins with copper hairpin tubes laced through it. The tubes are expanded mechanically so they press against the fin collars, then return bends and headers are brazed on to close the circuits.
Where it is used

Questions and answers
What do you need to quote a heat exchanger?
A drawing or a sample is best. Without one, send the duty (cooling or heating capacity), refrigerant, air volume, the space available, tube diameter and fin pitch if you have a preference, connection type and the quantity.
How is each coil tested?
Every coil is pressure-tested for leaks at 3.8 MPa. Coils are then inspected and the fins are combed straight before packing.
Which fin finish should I choose?
Hydrophilic fins shed condensate quickly and suit evaporators. Bare aluminum is the economical choice for condensers in clean air. Anti-corrosion coated fins are for coastal or polluted air.
Which refrigerants can the coils be used with?
R513A, R134a, R404A, R407C, R410A and R290. Tell us the refrigerant and working pressure so we can confirm the tube specification.
Can you produce to our existing drawing?
Yes. Most of our coils are made to customer drawings. If your tube pattern is not one of our twelve standard patterns, send it and we will check the tooling.
