Vessels
The ThermEx Thermal Maintenance System (TE) is used as external heating system on vessels, in cases where contamination from internal coil leaks cannot be tolerated and/or the wall temperature uniformity is critical to prevent condensation and corrosion. The ThermEx Bolt-on heating system offers improved performance over coils or panels and can also be used in addition to internal coils. It provides an even predictable distribution of heat and can be easily customised to accommodate for nozzles in the vessel wall.
Every heating element or panel is designed and fabricated for its unique location on the vessel. The profile of the element/panel will be shaped to fit the geometry of vessel heads, roof, cones, manholes etc. The prefabricated bolt-on panels are shaped already to be directly installed on the equipment using heat transfer compound to secure a conductive contact and avoid any air gaps for proper heat transfer.
For critical applications (e.g. Sulfur), detailed heatloss calculations are made to determine the shape and proper coverage of the ThermEx panels. Each lay-out is specifically engineered for each application and projected filling levels in the vessel so that condensation or freezing of the wall is prevented.

Piping
The ThermEx Bolt-on heating jackets on critical process piping have been the preferred steam tracing solution vs fully jacketed piping and tube tracing.
Typically for critical process temperature maintenance or melt-out requirements, this heating system provides significantly more reliability than traditional tube tracing.
This innovative heating solution eliminates the risk of cross-contamination and provides a uniformly distributed heating in the most cost-effective way.
The clamp-on heating elements/panels are installed applying a heat transfer compound (HTC) to ensure proper uniform heat conduction and high-strength banding or welded straps are utilized to install the system on the pipes, elbows, and nozzles.
Depending on the pipe size, wall thickness, insulation parameters, process fluid properties etc., the required heatloss compensation will be determined depending on the thermal objective of the system (freeze protection, temperature maintenance or melt-out within certainly timeframe).
The heatloss calculations determine the number of elements and proper area coverage of the ThermEx panels. Each lay-out is specifically engineered for each application.
