Uniquip’s GKSS range of hot oil heaters have been designed to excel at meeting the needs of industrial clients; emphasising cost-effectiveness, fuel efficiency, space efficiency, and longevity. Some of these heaters have been successfully operating for 45+ years.

GKSS had been operating and iteratively improving their designs since the 1940s before being acquired by Uniquip in 2012, and Uniquip have continued to build on that reputation for quality and cost-effectiveness for our industrial clients.

The GKSS heater range comes with the following features:
