Heat Exchanger Coil Expanding

Coil Expanding

At Tridan International we offer an extensive line of machines that can handle coil expanding. Furthermore, our expanding process is a mechanical expanding.  To describe what coil expanding actually is, it is the expansion of tubes that have been laced through the holes in a stack of fins to create an interference fit in the hole to lock the tubes and fins in place.

Coil Expanding and Joining Fins and Tubes

To make an assembly strong you should have a solid joining of fin and tube. The joint that is formed between the fin and the tube will  create a path for heat conduction. Also, if this joint is not done correctly, it may allow it to become a barrier to allow heat flow.  At Tridan International our expanding machines are used to expand the diameter of your tube.

No matter if you are looking for a high volume or a low volume coil expansion machine, Tridan has the  right machine for you. Our coil expansion machines can handle anywhere from large to a small coil and anywhere in between. We offer horizontal, vertical, semi-portable and tube end expansion machines.  With our Flexpander semi-portable expander series, it makes a great fit for smaller shops that still have a need for expansion of larger coils.

Large Volume Coil ExpanderThe Flexexpander – FE, an original Tridan product, is able to expand two tubes per cycle. This allows it to expand tubes with a U-bend or straight tube and return bend construction. In addition, to great innovations such as the Flexpander lines, Tridan offers and extensive line of coil expanding products that can benefit your company. While we do have products for smaller volume companies, we also offer larger volume machines as well.

A great example of a large volume coil expander is the Qual-Ekon- HE. This large volume coil expander is fully automatic and can handle the largest jobs.
