Trace Cable Heating Jackets and Blankets

Trace Cable Heating Jackets and Blankets

Removable, weather-resistant jackets with self-regulating cable elements for freeze protection and process temperature maintenance.

Custom Solutions

Removable Trace Jackets for Pipes, Valves, Tanks and More

HTS/Amptek® Traced Heating Blankets and Jackets are a great solution where instruments or other components need to be serviced. Traced Jackets may quickly be removed and replaced for temporary access. Large areas may be engineered using a modular approach having multiple heaters.

All Blanket Heating Systems are custom designed. Heaters, Insulation, Controls, Sensors and Power Distribution are components of a complete system. HTS/Amptek® can coordinate your System Design, then produce drawings for approval before fabrication may start.

Operational Flexibility Without Material Loss

Whether for freeze protection or process temperature maintenance, removable Trace Jackets offer operational flexibility. Often the Trace Cable installed permanently has to be cut away after insulation is removed. Trace Jackets eliminate that loss of time and material by permitting temporary removal and replacement with little required training.

Complex structures may be heated indirectly by simply enclosing them. Since these heaters are maintain-only, direct heat conduction is not required.

Fabrication, Thermal Design, Temperature Control and Distribution

Heat Loss, wet or dry conditions, freeze protection or process heat, area classification and temperature control are all considerations for Jacket design. For “Hazardous Area” applications, contact the HTS/Amptek® experienced design engineers for system design recommendations.

Construction Detail

Cable and Jacket Assembly Features

Trace Cable, Self-Regulating Heating Element

The Cable changes its output — it is maximum when cold and reduces as heat builds. The two conductors within are over-extruded then metal braided and over-extruded again for dielectric and mechanical strength.

Element, Sensors and Power Leads Attached to Liner

Traced Blankets use “pocket” or “loop” stitched features to locate the Trace Cable elements in an even matrix for optimum heat transfer. Lead Wires, Jumpers and Sensors are stitched/bonded in place with adequate strain relief and sleeving reinforcement where necessary.

Outer Fabrics and Closures

The outer Fabric, typically Silicone or Teflon® impregnated Fiberglass, provides flexibility, durability and moisture resistance. Velcro® flaps and D-Ring or Delrin Clip straps provide a final securing method.

Power Leads, Sensors and Plugs

Lead Wires and Jumpers (and Sensors if required) exit Jackets via Cordgrip CGB type fittings and then Flex Conduit or cordset. They are designed for the required custom length and may include seal fittings or plugs depending on the service location and area classification.

Control Systems

Heating Blanket Control and Distribution Systems

HTS/Amptek® offers temperature control and distribution solutions designed for trace cable heating systems. From freeze protection controllers to hazardous-area rated panels, every system is built for reliable, safe operation.

Standard Controllers

Standard, single zone, Temperature Controllers available from HTS/Amptek® are accurate and easy to use. Ideal for freeze protection, ambient and remote sensing switches energize when the temperature drops below the preset value.

NEMA Rated Wiring Distribution

Traced Heating Jackets use many ordinary, NEMA 4 and NEMA 7 wiring distribution arrangements to simplify removable installations. Multiple Jacket Systems can be enhanced using built-in Jumpers.

Custom Control Panels

Control Systems may be Wall, Floor, Rack or Portable Cart mount type. Contact support at HTS/Amptek® for expert design consultation.
