Control equipment


Thermosafe heats by induction and therefore has no heating elements. The maximum temperature is self-limiting, and the drum wall temperature is governed by the material inside the drum. In the vast majority of applications additional control in not required.

Thermosafe remains much cooler than the vessel being heated. The consequent lack of retained heat after switching off allows for very close temperature control, usually just using simple on-off devices. The choice of control will depend on your specific requirements, and might include temperature controllers (on/off or PID), timers, energy regulators or any combination of these or other components.

We supply a standard temperature and timer control panel, plus an open loop power control module. This is highly beneficial when heating sensitive oils and fats that degrade or deteriorate if the temperature differential between centre and edge of the drum becomes too large, or if drums of material need to be held at an operating temperature for considerable periods of time without wasting excess energy. 

For precise temperature control applications, we supply a magnetic pad heavy duty thermocouple that can be attached to the drum wall. In a hazardous area, this is connected via a zener barrier to the control panel mounted in the safe area.

Handling Equipment

Thermosafe is an encapsulated induction coil. Both ends of the cylinder are open, allowing the heater to be lowered over the drum or vessel. Alternatively, the drum can be lowered into the heater but, as Thermosafe weighs less than 50kg, this is unlikely to be the most convenient arrangement. 

Top, bottom or side flanges may be used to attach handling equipment, if preferred to manual lifting. 

A range of dedicated products is available but many standard forms of handling device are suitable.


Handling Equipment




Multi-purpose lifting bar:  Allows Thermosafe to be handled by forklift truck or overhead hoist.

Mobile Lifting frame:    To enable quick and easy lifting of Thermosafe, on and off drums, using a geared hand winch with automatic brake. Ideal where a portable facility is required.
