Drum Heater – Rigid Drum Heater Enclosure IDR/200L/230V & 400V

Thermocoax Isopad IDR drum heater enclosures are designed to provide medium flow and process temperature to 200 litre steel or plastic drums.

The IDR drum heaters are constructed from two pieced metal housing which can be opened and closed via hingers and fasteners. The IDR is fitted with special castors to allow the unit to be moved with ease eliminating overhead lifting and to ensure stable operation even on uneven surfaces.

The electric heating elements cover the entire inner surface ensuring the drum is heated consistently and these heating elements are insulated to prevent heat loss through the outer wall. The temperature of the drum heater is regulated by a mechanical thermostat with an ambient temperature range of -20ºC to +40ºC

An optional insulated lid can also be supplied to reduce heat loss through the top of the container and Isopad IBDR base drum heaters can be used alongside the IDR drum heater enclosure to further improve the heater capabilities.

T&D also offer a full range of IBC & Drum heating jackets and heaters.
