Fit and forget thermostat keeps frost and snow at bay

Supplied ready to go from Spelsberg, the HT system comprises a robust and reliable mechanical thermostat, safely fitted into a robust enclosure. Spelsberg is one of the worlds leading developers, makers and suppliers of electrical enclosures and uses its well-proven TK model for this thermostat protection role.


TK enclosures are one of Spelsberg’s most popular ranges. Made of strong, stable polycarbonate (with a new aluminium alternative option now also available), they are IP66 rated. This means they can stand up to extremes of temperature, dust, dirt and humidity, and cope with strong water blasts and sharp impacts. Thus winter temperatures, lashing rain, cold winds and snow are going to meet their match.

Upon receipt, all users need to do is connect the HT thermostat to the trace heating system to create an intelligent and effective frost protection system.

Design details such as a clamping cable gland and an integral polyurethane cover gasket seal the interior of the TK from whatever Ran, the Norse God of Weather, can throw at it. Upon receipt, all users need to do is connect the HT thermostat to the trace heating system to create an intelligent and effective frost protection system.

The secret of the Spelsberg HT thermostat range is its simplicity, which makes selection and specification easy while also ensuring resilience in operation. Every winter scores of the UK’s industrial facilities suffer from damaged pipes brought on by the cold weather. Loss of production and repair costs can be considerable, which make an HT system and a bit of forethought look like a very good investment.”
