Temperature controls are provided to:
- Ensure Temperature Safty
- Ensure Process temperatures
There are three types of control systems that we can use;
1) No control. The heater is constantly energised and the final application temperature will be a function of the heater output, insulation and local ambient conditions
2) Ambient control. The heating system is controlled by the ambient temperature. This is typical for Fast protection systems where no critical temperature limits are imposed.
3) Surface Control. The heating is directly controlled as a function of the work piece temperature.
When temperature controllers are used they should be rated for the requirements of the installed area.

Our Weatherproof Range – temperature range to 150C
In addition to our Weatherproof range we also offer a complete range of Ex certified equipment.
Hazardous Area Thermostats
We provide Pipe sensing models that have a protected capillary tube with surface mounting sensor bulb. Air sensing types have an air sensing model for frost protection purposes. All thermostats are adjustable over a temperature range and are 'ON – OFF' units with an electrical switch operated by expansion of the liquid in the sensing bulb or capillary. The units are suitable for use in corrosive and dust laden atmospheres.
SIRA approved for Zone I and Zone II hazardous areas
