Extrusion Heated Hoses

Heating:  The heating element is wound around the stainless steel pressure braiding; the heating element is then covered with a glass fibre-insulating layer. A nickel-plated copper braiding is wound over the insulation; this also acts as a safety earth.

Thermocouple:  The thermocouple sensor is placed in contact with the stainless steel pressure braiding below the heating element. The standard temperature sensor fitted is Fe-CuNi, “J” type. Other types of sensor can be fitted on request, e.g. NiCr-Ni or PT100.

Insulation:  Several layers of glass fibre insulation cover the heating element and thermocouple. This in turn is covered with a silicone foam layer, which offers a high degree of thermal insulation and a ‘warm to touch’ property, reducing hand and arm skin burns.

External layer:  An external polyamide braiding protection helps to protect the insulation from scuffs and abrasions. For additional protection a stainless steel braiding is available.

Connections: The standard heating hose are supplied with a single cable 1.5M long and a 7-pin DIN plug. The plug comprises of single phase to pin 1 or 2, a neutral supply to pins 3 or 4. Pins 5 and 6 are thermocouple pins. Centre pin7, is the earth pin. A panel-mounted socket can be supplied to enable simple connection to the spare tool zone temperature controller.

End Fittings: The end fitting or threaded connector are available in metric and BSP threads. There are also two styles of connectors Plain Flanged End and Universal Conical 60º (female)
