Heat-cool combinations

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.

Screw-in heaters are versatile and intended for heating liquid media in industrial and commercial applications. When selecting, the specific surface load permitted for the respective medium must be observed and checked by the customer. EHK G1 1/2 are mainly used to heat water and aqueous solutions. 3 tubular heating elements ø 8,5mm made of stainless steel 1.4404 resp. Incoloy 825 brazed in G1 1/2″ thread made of brass (lead free) or stainless steel. Connection to 230/400 V3 (N), rotatable stainless steel terminal box. Use e.g. in washing machines, dishwashers, tempering equipment, laboratory equipment. The heaters are also suitable for water heating with photovoltaics, primarily the EHK G1128xxx series. Combination with all common PV controls possible, stepless power output. Type EHK G112-A with built-in thermostat 0-95°C Type EHK G112-AB with built-in thermostat/limiter 30-80°C / 100°C Type EHK G112-U without integrated control unit

In the highly innovative machinery and equipment construction area, our heating elements and equipment find mainly application in the tasks of heating, maintaining temperatures or evaporating liquid or gaseous media. The installation of our equipment can take place both in nonhazardous and hazardous areas of zones 1 and 2.

Especially for high-cavity PET plastic injection moulding there are various industry standards of clamp-band nozzle heaters available. Most common are the Axial Clamp-Band Heater and the Two-screw Clamp-Band Heater. Our HotCoil cable heaters with clamp band represent a highly demanded and very flexible clamping system, especially for heating larger nozzles and bushings with high power. The size-variable customizable clamp bands counteract the heating's thermal-related "lifting ambition" during heat-up and thus effectively prevent a possible critical overheating. For an even better protection all HotCoil heating elements can also be provided with an integrated thermocouple. As alternative to our standard clamping mechanism with welded clamping elements a space-saving lug clamping mechanism can be supplied.
