Gas heated emitters The range of available gas-fired emitter modules with different functional principles ensures an optimal solution for each individual application. The modular concept permits easy retrofits at a later date to meet changing needs. Metal Emitter K 6.500 The K 6.500 metal emitter has the highest efficiency and is the most robust of all gasfired IR emitters on the market. Ceramic Emitter K 10.000 The K 10.000 ceramic emitter has the highest specific output power and is ideally suited for installation wherever high drying capacity is required in a limited space. Fibre Emitter K 5.500 The K 5.500 fibre emitter is used wherever short heat-up and cool-down times take top priority over power and efficiency.
