The ThermEx Thermal Maintenance System is used as external heating system on drums, in cases where contamination from internal coil leaks cannot be tolerated and/or the wall temperature uniformity is critical to prevent condensation and corrosion.
Through the TE elements steam, hot oil or glycol water is conveyed as heating medium. The heated TE elements will transfer the heat at first to the drum wall and secondly to the process medium.
The shape of the rectangular sections provides a wide heating surface to its component guaranteeing an optimal heat transfer. The use of heat transfer mastic between TE-system and wall will avoid any air-gap and additionally will act as corrosion barrier. Constant and equal heating will avoid cold or hot spots.
