Industries we serve

Heating built for the industries that run on temperature.

For over 35 years our heaters have run in plants across oil & gas, pharma, food, refrigeration and beyond. Whatever your process needs to reach — and hold — we engineer the heater to the application, the materials and the environment.

What we heat, sector by sector.

Each sector below shows the heating challenges we solve and the ranges we build for it — every unit engineered to your application, materials and temperature.

Oil & Gas

Pipelines, tanks and instruments that have to keep working through cold and remote conditions. We supply heat tracing to stop lines freezing, drum and tank heating to hold fuels and additives at viscosity, and winterization for valves and instrumentation.
Typical applicationsPipeline freeze protection · Viscosity maintenance · Tank & vessel heating · Instrument winterization
Heaters we supply

Pharmaceuticals

Processes that demand clean, repeatable, closely controlled temperature. Our flexible and etched-foil heaters bring precise heat to reactors, vessels and lab equipment, while heat tracing protects critical lines — all built to consistent, documented quality.
Typical applicationsReactor & vessel heating · Lab & analytical equipment · Line freeze protection · Drum & IBC heating
Heaters we supply

Food & Beverage

Ingredients and product that need gentle, even heat to stay pourable and processable — chocolate, oils, honey, fats and syrups. We supply drum and IBC heaters, process heaters and hygienic surface heating built to your line.
Typical applicationsIngredient & drum warming · Viscosity control · Process & oven heat · Surface heating
Heaters we supply

Refrigeration & Cold Chain

Keeping cold equipment clear of frost, ice and condensation so it runs reliably. Our freeze-protection range covers door frames, drain lines, evaporator coils and drip trays across cold rooms, display cases and freezers.
Typical applicationsDoor & frame heating · Drain-line heating · Coil defrost · Condensation control
Heaters we supply

Plastics & Polymers

Material that has to be dried, kept flowing and processed at temperature. We supply hopper and dryer heating to stop bridging and moisture, plus band, nozzle and process heaters for moulding and extrusion.
Typical applicationsHopper & dryer heating · Barrel & nozzle bands · Material drying · Moulding & extrusion
Heaters we supply

Chemical Processing

Reactors, vessels and lines handling fluids that must stay at temperature — or be protected from freezing and crystallizing. We supply vessel and drum heating, process heaters and heat tracing engineered to your media and duty.
Typical applicationsVessel & reactor heating · Drum & chemical heating · Pipeline tracing · Crystallization control
Heaters we supply

Power & Utilities

Plant and water infrastructure that has to stay operable in the cold. We supply freeze protection and heat tracing for pipework and water lines, plus panel, instrument and process heating across generation and distribution.
Typical applicationsPipe freeze protection · Water-line heating · Panel & instrument heating · Process heating
Heaters we supply

Railways & Transport

Equipment exposed to weather, vibration and condensation. Our flexible and foil heaters handle cabinet and battery warming, condensation control and de-icing, with heat tracing for exposed lines and points.
Typical applicationsCabinet & condensation heating · Battery warming · De-icing · Point heating
