M/s. ENCON THERMAL ENGINEERS (P) LTD. have introduced "RAD-HEAT Gas Heating Elements" which are infrared heating systems, closest to heating with the sun. These elements are effectively replacing all existing electrical, thermic fluid and hot air systems (up to working temperatures of 550°C) as they involve the clean and safe qualities of electrical heating with the added advantage of tremendous savings in cost of operation (savings to the tune of 25-70%.) Tubes of 3"-4" diameter are placed directly in the oven/tank where the heating is required, just like in immersion heaters. Gas is burnt inside the tubes (no direct exposure to the area to be heated and therefore, no contamination) which get heated and, in turn, emit radiant heat in the form of electromagnetic waves to heat up material in the oven/tank. The temperature control is thermostatic (just like in electric heaters) and existing circulation fans, etc. can be used. Only radiant tubes are installed additionally. No major changes need to be done in the system. The radiant tubes can be installed in various shapes such as U, W, S, etc. except that the first length should be 1 metre straight horizontally. The total system generally requires only one day for installation and has a payback period of 6-8 months. The system requires absolutely no maintenance and is based on the fundamental of FIT IT AND FORGET IT. The Rad-Heat GAS HEATING ELEMENTS are successfully being used in various applications (upto 550°C) such as
