Stable and Efficient
Twin tube heaters distinguish themselves by their exceptional stability and high power density. Fast response medium wave heaters can be supplied in all lengths up to around 6m.
Consequently, it is possible to transfer high power over long lengths. The heaters offer long operating life. Gold reflectors double the effective emitted radiation.
The heaters transfer heat at a medium wave spectrum and are thus particularly suitable for drying processes. The high absorption by surface layers and films makes them particularly applicable to thin materials, while the heaters' penetrative effect renders them highly effective for use in plastics processing.
The heaters can be switched on and off in seconds, making them ideally suited for processes with short cycle times.
Fast Response Medium Wave IR Heaters
Infrared heaters allow optimum matching
Infrared heaters are available in different forms matched to different requirements: short wave heaters for deep penetration or medium wave heaters for rapid heat-up of surfaces and thin films.
The wavelength at which infrared is emitted significantly influences the effectiveness of the heating process. Perfectly matched infrared heaters can allow overall energy savings of up to 50%.
