Tubular heaters

Tubular heaters are the base of electrical heating and this product group has been model for the innovative heating techniques we are using today. IHPs tubular heaters are found in a variety of heating products and are used for heating of air, gases, liquids, salts, minerals and solids through heat conduction or radiant heat.

IHPs tubular heaters are made of metal tubes there we place a power adapted spiralized resistance wire in the center of the tube. Around the resistance wire, magnesium oxide is compressed which will be the isolator between the electric resistor wire and the outer tube. The tubular heater is then sealed, gets its connections and bents, spirals and forms according to wishes. Common fixations are with flange, nipple or threaded plug.

IHP designs qualitative tubular heaters. We offer a wide variety of heater materials such as copper, stainless steel, acid resistant stainless steel, 254 SMO, Incoloy® 800, Incoloy® 825, aluminum and titan. When used in baths with corrosive liquids, we also have the opportunity to coat the tubular heaters with PTFE (Teflon®) as an extra protective layer.

For installations without protective earth, IHP can offer double insulated tubular heaters for increased personal safety. The tubular heaters can also be fitted with integrative fuse for extra passive safety.

IHP primarily provides customized tubular heaters but we also have a standard range for quick delivery.

For temperature control and regulation we are happy to help and design complete control cabinets.

Control cabinet PID

IHPs smallest control cabinet is a “stand alone” system that fits a variety of heating applications where the need is one heating zone and one sensor. In our PID controller there is plenty of intelligence that comes in handy when needed for even heating, ramp functionality, maximum adjustable temperature, program steps with different set points or only temperature control that is CE marked and approved.

We supply the control cabinets in three standard versions and you simply select the cabinets according to the type of sensor that fits your process. IHP can also offer some popular options such as quick plug between heater and control cabinet and help program the control cabinet with the parameters that are important in your process.

The control cabinet can advantageously be used in conjunction with all IHPs heaters that need less than 16Ampere.
