Our products

Product category: Heating elements

Nozzle band heaters

Nozzle band heaters are used primarily for heating the nozzle area of injection molding machines. They are also suited for heating any metallic cylinders used in the industrial sector.

Any other possible uses must be clarified with the manufacturer who must give his express approval. Otherwise the warranty is void and no liability will be assumed.

Flat heaters

General Information

Flat heating elements are used primarily for heating dies used in the industrial sector, in particular dies for processing plastics. They may also be implemented to heat all metallic containers and troughs that have flat external surfaces and are used in the industrial sector.

Any other possible uses must be clarified with the manufacturer who must give his express approval.

Operating Conditions and Safety Instructions

The maximum operating temperature is 300°C. It is necessary to make sure that the relevant fire safety instructions are observed and the appropriate safety precautions have been taken. Both the flat heating element and the material to be heated may not be subjected to any critical conditions (such as fire, explosion, formation of smoke and gas, etc.). Only suitable heat-resistant cable sets may be used due to the high temperatures. It is also necessary to ensure that sufficient protection is provided against contact, dust and moisture.

The maximum surface load of the heating elements may not exceed 3.5 W/cm². Nonconforming installation and incorrect selection of control equipment may result in defects and accidents. Any other conditions of use or diverting from the intended use must be clarified with the manufacturer who must give his express approval. Otherwise the warranty is void and no liability will be assumed.

Installation Instructions

The flat heating element must be mounted so that it fits the form of the die to be heated in such a way that the heater and the surface to be heated are firmly connected to each other. To this end, use the supplied steel pressure plate. Mechanical damages due to external influences must be prevented without fail.

In case the connection is not form-fitting, the flat heating element will be destroyed by overheating.

Electrical Installation

The heater may only be installed by an authorized electrician or qualified personnel who have had proper instruction.

Make sure that the indicated operating voltage matches the supply voltage. Heat-resistant cabling must be used for all connections (see Operating Conditions and Safety Instructions). Cables must be installed in such a way that they do not come in contact with sharp-edged metal parts or hot surfaces.

Cylinder heaters

General Information

Ring-shaped cylinder heaters are used primarily for heating metallic cylinders used in the industrial sector, in particular with injection molding machines, extrusion dies, extrusion cylinders, etc.

Any other possible uses must be clarified with the manufacturer who must give his express approval.

Operating Conditions and Safety Instructions

The maximum operating temperature is 300°C. It is necessary to make sure that the relevant fire safety instructions are observed and the appropriate safety precautions have been taken. Both the ring-shaped cylinder heater and the material to be heated may not be subjected to any critical conditions (such as fire, explosion, formation of smoke and gas, etc.). Only suitable heat-resistant cable sets may be used due to the high temperatures. It is also necessary to ensure that sufficient protection is provided against contact, dust and moisture.

The maximum surface load of the heating elements may not exceed 3.5 W/cm². Nonconforming installation and incorrect selection of control equipment may result in defects and accidents. Any other conditions of use or diverting from the intended use must be clarified with the manufacturer who must give his express approval. Otherwise the warranty is void and no liability will be assumed.

Installation Instructions

The ring-shaped cylinder heater must be mounted so that it fits the form of the cylinders to be heated in such a way that the heater and the surface to be heated are firmly connected to each other. That's why a maximum torque is recommended. A torque between 15 and 18 Nm should be maintained with the aid of disk springs.

Mechanical damages due to external influences must be prevented without fail. During the initial heat-up phase, the ring-shaped cylinder heater must be retightened. Pretension heaters with the aid of compression springs only to the extent that sufficient space is available. In case the connection is not form-fitting, the ring-shaped cylinder heater will be destroyed by overheating.

Electrical Installation

The heater may only be installed by an authorized electrician or qualified personnel who have had proper instruction.

Make sure that the indicated operating voltage matches the supply voltage. Heat-resistant cabling must be used for all connections (see Operating Conditions and Safety Instructions). Cables must be installed in such a way that they do not come in contact with sharp-edged metal parts or hot surfaces.
