ABOUT TRACE CABLE HEATING JACKETS

Custom Heat Traced Jackets for Freeze Protection and viscosity control offer quick and easy install and removal. Traced Heating Jackets are clean, modular, low watt density heaters. These custom designed, insulated Heating Jackets, use commercial Heat Tracing Cable for their heating elements. The robust, stitched construction configures into preformed shapes with Self Regulating Heating Cable inside, including the necessary hardware and termination fittings to maintain approvals for Hazardous and Non-Hazardous areas. Freeze protection is necessary to keep liquids flowing when weather conditions are not ideal. Viscosity Control, to flow thick liquids from oil to wax and chocolate, requires heating for proper temperature maintenance. Traced Jackets offer the advantage of being able to be removed and reinstalled, when valve or instrumentation maintenance is necessary.

TYPICAL AND SPECIAL FEATURES

Jacket sizes:
Large Heating Jackets are limited by weight, typically 50lbs (23kg), but may be constructed in multiples to fit large surfaces. Small Heating Jackets may be constructed to fit ¾ inch diameter tubing and fittings. Note that Heating cables are less flexible than HTS/Amptek® Heating Tape elements, and are difficult to fit in small Jacket formats.

Construction:
The Jacket inner fabric liner of Teflon or Silicone supports the mechanically attached Heat Trace Cable and Sensors. Insulation layers are placed over top and outer fabrics enclose the assembly. All Jackets are pre-formed and double stitched to form the necessary 3D shape. The materials of construction fabric choices include Teflon Silicone Neoprene and Vinyl. Insulation types include Fiberglass Mat and closed-cell Foam varieties to provide durability, lighter weight and moisture protection.

The Self-Regulating Heating Element:
Self-Regulating heaters provide more heat at low temperatures and less heat as the ambient temperature warms. HTS/Amptek® selects the best available Trace Cable for the application. Whether the goal is freeze protection, viscosity control or process heating, there is a style of heater that would be best suited for the application.

Temperature Capability:
Heat Trace Cables are all rated for continuous and maximum exposure temperatures. This value varies depending upon the style of cable used. Generally, however, using the highest temperature rated cable available, we do not recommend use above 300°F (150°C).

Heated Zones:
Traced Jacket Systems, for freeze protection, may be designed to “daisy-chain” such that multiple Jackets can operate in a single zone. Jackets may have connecting plug and receptacle configurations so that they may be easy to remove and reinstall. For process applications, each Jacket may have its own dedicated power and sensor leads. Trace Calbe in-rush current is considered during circuit sizing.

Temperature sensors:
Built in thermal sensors such as RTDs or Thermocouples can be installed for process temperature measurement, or directly on the heating element for sensing limit temperature. Snap Switches and Thermostats may be used for limit, or low-cost temperature control solutions.

Cutouts and Penetrations:
Cut outs and slits for supports, ports and other hardware are typical of most applications. HTS/Amptek® designs preformed Jacket configurations with gusseted holes, slits and seams to provide great fit and easy install and removal. Additional flaps and straps cover the exposed seams.

Closures:
Most common Closures are Velcro® flap and D ring strap or lacing eye closure methods, however quicker and cleaner methods include convenient snaps or Delrin® Clips.
