In 1986, unitemp, a privately owned company was established, manufacturing heating elements for the plastics & packaging industry in South Africa.
The company diversed into other markets supplying customised heating systems, and measurement and control instrumentation.

In a strategic move to gain leverage for a future involving more complex project work, unitemp entered into a partnership with Thermon Group Holdings Inc.
On 1 April 2015 a new entity emerged called Thermon South Africa (Pty) Ltd.

Thermon holds a unique position as the only international trace heating company completely dedicated to its industry. Since 1954, Thermon has concentrated its efforts exclusively on heat tracing. Thermon is headquartered in Texas USA, with offices worldwide.

With the overlap in heating expertise, Thermon SA has the additional backing to fulfil the needs of the power generation, gas & oil + mining and minerals processing industries.
