Isothermal (Pty) ltd started operations in 1979 supplying a Heat Treatment Service to the Industry. It started with flame hardening and became a leader in its field. Over the next few years the flame hardening was slowly discarded and replaced with Induction Machines.
The first Induction machine was installed in 1988 and over the years we have acquired 6 induction machines to allow us to cater for most applications and customers requests.
We have Low, Medium, and High Frequency Induction Machines and therefore able to accommodate to a variety of job specs and customers needs. We have a staff of 15 employers consisting of 6 operators,two forklift drivers, one labourer and one cleaner. The rest of the staff is sales and management. Our staff are loyal and have long services to the company ranging between 15 to 25 years.
