MEDIUM WAVE INFRARED HEATERS - KRELUS IR
The unique technology used in the fast medium-wave KRELUS IR heater allows operation with precise temperature control. These infrared heaters have very rapid reaction time, which allows them to be switched on and off for brief periods to allow energy savings in comparison to traditional radiation systems.
KRELUS IR heater systems are suited to a range of applications, including:
• Evaporation of liquids
• Drying inks
• Melting plastics
• Installation in ovens and drying tunnels
• Speed improvement on existing production lines

STANDARD INFRARED HEATING MODELS
The company have recently added two standard models of made-to-measure KRELUS IR infrared heaters. These use identical technology, and are available in sizes 248mm x 248mm, 123mm x 496mm, 123mm x 248mm and 78mm x 496 mm. Power densities of 20 kW/m2, 26kW/m2, 32kW/m2, 40kW/m2 and 50 kW/m2 are available.
The two new types of heater module allow clients to construct individually controlled radiation zones in any desired size. These are particularly suited for use in thermoforming equipment.
KRELUS IR infrared heaters require virtually no maintenance, as they have no moving parts. Any necessary foil replacement can be easily achieved by the client's own personnel.
ELECTRONIC HEATER OUTPUT CONTROLS
Electronic controls allow the user to regulate heater output continuously on any of the following principles:
• Machine speed
• Humidity (measured by probe)
• Temperature (measured by probe)
• Optical pyrometer
• Manual regulation by potentiometer
