Due to the physical properties of almost all materials which can be treated by infrared, the medium-wave radiation in the range of 2,5 µm – 3,5 µm gets the best results. This is just the emission range where our KRELUS-IR-heaters gets the highest performance Our modular and custom made IR-heaters leave all opportunities for the individual, almost endless applications. The KRELUS-IR-heaters are working with the shortest reaction time ON/OFF. This guarantees the highest economical use of electrical energy and fastest adaption to required temperatures on product surfaces. Consequently our IR-heaters are highly active with gentle action for treated products and even more important: they are energy saving.

In order to meet the demands for robustness and efficient heat output, we have embroidered the heating element on a glass mesh fabric carrier material. Between the meandering arrangement of the heating strands, we integrate a recess for the temperature switch in the CAD layout. In addition, a second wire is laid concurrently as a PTC thermistor for the electrical connection of the safety switch. After the technical embroidery process, the safety switch is inserted and connected by our company’s respective department. Each prefabricated element is tested for functionality and performance in the final inspection and is delivered to the customer after passing the test. As a semi-finished product, the infrared heating element on glass mesh fabric can be further processed by the customer, e.g. in connection with silicone, rubber or epoxy resin.

Aramid fibers are suitable for very demanding applications and they are widely used in the firefighting industry (manufacturing of firefighters’ clothing) because of their flame retardant properties. Aramid is not only fireproof, the aramid fibers also have a high tensile strength, which is why they are often used for bulletproof vests (military and police) or for armoring selected emergency vehicles. A special property of aramid nonwovens is its good thermal insulation. The laid heating wire creates a very high heat output, which is insulated by the nonwoven. Aramid has a high heat resistance, which is an enormous advantage since laying the heating wire generates a very high heat output which is further enhanced by the insulation provided by the aramid nonwoven carrier. In addition, the nonwoven is either not combustible or flame retardant and can be used for a temperature ranges of up to 200°C.

The Uni Condens 8000 F stainless steel condensing boiler is the ideal solution for heating applications between 145 and 640 kW. The boiler can run either on gas or on low-sulphur heating oil. Installation is easy as the boiler is compact, takes up minimum space and weights relatively little. Intelligent water flow using separate return connections provides the ideal conditions for optimum condensation and thus high standard utilisation ratios. When running on oil, the Uni Condens is capable of a standard utilisation ratio of up to 104%. Up to 110% is even possible when running on gas. The Uni Condens has an effective condensate heat recovery surface with special profiling of the tubes, so that the maximum utilisation of the condensation potential is achieved. The construction with burnout combustion chamber ensures that there is clean combustion and low emissions. The two return flow sockets guarantee optimum separation into high-temperature and low-temperature heating circuits.
