HPT Power-Limiting Heating Cable
HPT Power-Limiting Heating Cable
High performance HPT power-limiting heating cables are designed specifically for process temperature maintenance or freeze protection where high maintain temperatures or high temperature exposure is required.
A coiled resistor alloy heating element provides the power-limiting feature of HPT. This PTC (Positive Temperature Coefficient) characteristic decreases the cable’s power output as the heat-traced product temperature increases and allows the cable to be overlapped during installation.
The composite construction of the heating element and fiber substrate, plus an additional fiber cushion layer, provide an exceptionally durable high performance heating cable.
APPLICATION
High performance D1-HPT power-limiting heating cables are designed for process temperature maintenance or freeze protection where high maintain temperatures or high temperature exposure is required. A coiled resistor alloy heating element provides the powerlimiting feature of D1-HPT. This PTC (Positive Temperature Coefficient) characteristic decreases the cable’s power output as the heat-traced product temper-ature increases and allows the cable to be overlapped during installation. The composite construction of the heating element and fiber substrate, plus an additional fiber cushion layer, provides an exceptionally durable high performance heating cable. D1-HPT cables are specifically approved for use in Division 1 hazardous (classified) areas.
BASIC ACCESSORIES
The D1-ECK kit (pictured below) is required for power connection and heating cable termination in Division 1 hazardous (classified) areas. D1-ECK-2 kits for inline splices and D1-ECT kits for T-splices are also available. If D1-HPT cable terminations and/or splices are located more than 1’ (305 mm) outside the Division 1 hazardous area, Division 2 approved termination kits may be used. For additional information on these accessories, refer to Form TEP0010.
