What we make

RHT (NZ) LTD

Our radiators are manufactured from flat sheet steel which has been cold pressed to a configuration that has proved over the years to be a most successful design. These pressed panels are then faced together and TIG welded by an automatic process to make a flawless radiation panel.

The completed panels are then assembled on a jig which ensures accurate alignment and positioning of the individual panels. They are then MIG welded by experienced and well qualified welders.

After a cool-down period the completed radiator is given a final proving test in a deep water bath and high pressure air is injected. In the unlikely event of a leak this is immediately apparent and the unit is withdrawn from the process for repair and re-test. The radiators are then packaged to the clients requirements and shipped. Our radiators are suitable for all forms of cooling, both natural and forced.
