Ceramic Infrared Heaters
Radiant elements that heat the surface of the work directly, without heating the air in between. Trough and flat panel forms, with or without a reflector.

How it is built, and why that matters
A resistance coil is embedded in a moulded ceramic body. When the ceramic is hot it radiates in the medium wave infrared band, and that radiation crosses the gap and is absorbed at the surface of the work. The air in between is barely heated at all.
That is the whole argument for the technology. Where a convection oven has to bring the air, the enclosure and the fixtures up to temperature before the job gets hot, a radiant panel puts its energy where the job is.
Element form controls the pattern. A trough concentrates the radiation into a band, a flat panel spreads it evenly over an area, and a reflector behind either of them sends back the half that would otherwise be lost.

Options
Everything you can order, given a code, a description and a rating. No Indian heater manufacturer publishes this today. It is what turns a quotation phone call into a part number, and every code here is the code that appears on your requirement document.

01 Element form
- FT
Trough
Concentrates the radiation into a band.
- FF
Flat panel
Even spread over an area.
02 Inbuilt thermocouple
- TC0
None
Control by power percentage or from a separate sensor.
- TCK
Type K
Closed loop control on the element face.
03 Reflector
- R0
None
Element only.
- R1
Fitted reflector
Directs the back radiation forward.
Frames, cassettes and multi element panels are made to order. Tell us the area to be covered and the target temperature and we will lay the elements out.
Choosing the right heater
Distance sets the intensity
Radiant intensity falls off sharply with distance. Halving the gap does far more than adding elements, and it is usually cheaper.
The material decides how much is absorbed
Two materials at the same distance under the same element will reach very different temperatures. Tell us what is being heated.
Control the element, or control the work
An inbuilt thermocouple holds the element face steady. Holding the work steady needs a sensor looking at the work. Say which one the process needs.
Why these fail early
Telling a buyer how a product fails is the most credible thing a manufacturer can publish, and it is the fastest way to stop the same failure arriving twice.
- Too far from the workThe commonest specification error. Output is fine, intensity at the surface is not.
- No reflectorHalf the radiation goes backwards into the frame.
- Thermal shockCold draught or splash onto a hot ceramic body cracks it.
- Wired without power controlFull on and full off cycling stresses the ceramic and overshoots the work.
