Rosamon Industrial Immersion Heaters are specialist heaters designed for commercial applications. The Rosamon brand is renowned and widely used in commercial catering, food processing, utensil washing, engine and generator set pre-heating systems.

Rosamon Immersion Heaters are a truly unique range of custom built immersion heaters, incorporating close thermal control and added protection against boil dry operation only imitated elsewhere. Rosamon formed elements and Immersion Heaters can be constructed to enable the use of multiple thermostats and contactors to ensure reliable and efficient operation and minimal additional wiring of external components for the installation contractor saving time and money.

TPFay (Kirkby) Ltd acquired Heating Equipment Ltd. in 2004. The company had been designing and manufacturing “Rosamon” Immersion Heaters since 1931 . Throughout this period the Rosamon brand has earned an unparalleled reputation for quality and reliability.

High level positioning of control or limit thermostats attached directly to the heating elements provide a degree of protection against gradual boil-dry in open tank applications.

Washing and sterilising applications often provide the harshest of environments for equipment and operators to work in.
