Product Description

The INDEECO HSRX is the highest-temperature self-regulating heat trace cable in the INDEECO lineup — engineered specifically for applications where steam cleaning is required and process temperatures push the limits of standard cable. With a maximum maintain temperature of 300°F (150°C) and intermittent exposure tolerance up to an exceptional 482°F (250°C), the HSRX handles the most demanding industrial piping, chemical processing, and high-temperature freeze protection scenarios without flinching.

The all-fluoropolymer construction — fluoropolymer jacket (red), fluoropolymer insulation, tinned copper braid, and nickel-plated copper bus wires — provides outstanding chemical resistance and durability under steam washdown conditions. The HSRX PTC self-regulating core automatically adjusts heat output based on ambient pipe temperature, eliminating the risk of overheating at cable overlaps and reducing energy consumption.

HSR / HSRX Install

Every installation requires these 4 components:

# What It Does Model
1 Power Connection Kit — HSR rated PCA-81J
2 HT Core Sealer — seals every field-cut cable end 1034390
3 End Seal Kit — HSR rated, steam tolerant ESA-81
4 Caution Labels — NEC required HTCL-1

⚠️ Never use LT core sealer (1034096) or ESA-ES end seal on HSR/HSRX — these are not rated for the operating temperatures involved and will fail.

Also strongly recommended:

  • Pipe Standoff Kit (PCA-81P) — critical on hot process lines

  • Pipe Straps (HTPS-6 or HTPS-10)

  • Line-Sense Thermostat (HTTS-L or HTTS-EPL for Div 2)

  • HT Controller (HTCTRLR-1 or HTCTRLR-2) — recommended for critical process lines

  • RTD Sensor (HTRTD-25) — required if using a controller


Applications: 

Industrial process piping · Heavy-duty freeze protection · High-watt-density thermal maintenance · Chemical and petrochemical lines
