Protherm Engineering was formed by Mike Brinkworth and Keith Clark in February 1984. The formation of the Company was made to exploit the knowledge Mike Brinkworth had of high velocity fired furnace systems within the client base that Keith Clark had developed in the galvanizing industry. Simon Clark joined the company at its inception.

The galvanizing industry has always been the main focus of the company’s activities and Protherm has developed a significant customer base both at home in the UK and overseas.

Over the years it has expanded its product range based on one overriding objective - to produce rugged, well engineered equipment eminently suited to the hostile environment encountered in hot dip galvanizing. The Company has always shunned gimmicks in favour of properly engineered products designed for engineers.

Acknowledging the fact that it is a small company, customers’ priorities are never ignored. Protherm encourages open dialogue with clients and in the words of the co-founder “We like to think of ourselves as a total partner”.
