G&M can now supply these Withnell type finned tubes.
These are high quality tubes made from copper and with copper cooling fins.
The tubes are custom made to the required length with a standard 1/2” OD. The ferrules are 1/2” ID x 5/8” OD.
Lead times can be as low as 2 weeks from order date.
There are three styles of tube (pictured above).
The O tube is designed to prevent blockages by leaving a clear path for air to pass through the heat exchanger.
