Eltherm Ex-it/L & Ex-it/S

End-of-Line Termination & Monitoring for Trace Heating Systems

The Eltherm Ex-it/L and Ex-it/S are robust, outside-the-insulation end-of-line splice and termination devices engineered for use with Eltherm self-regulating heating cables including ELSR-H, -SH, -SHH, -LS, and -N. These components play a vital role in maintaining the integrity, reliability, and visibility of your trace heating system’s performance.

The Ex-it/L and Ex-it/S are engineered for demanding industrial environments where external terminations and visual system diagnostics enhance safety, efficiency, and maintenance access in the following applications:

Pipelines & Long Pipe Runs
Valves, Pumps, and Process Equipment
Chemical & Petrochemical Facilities
Automotive Manufacturing
Power Generation Plants

With over 40 years of industry experience, Thorne & Derrick’s team of hazardous area heating and trace heating specialists deliver tailored solutions backed by expert support. We offer complete system design, including heat loss calculations, intelligent control systems, and product specification—ensuring full compliance with safety standards and seamless integration with your operational requirements.

Purpose-Built Integration with Trace Heating

The Ex-it/L and Ex-it/S serve as essential components for terminating self-regulating trace heaters at the end of the heating circuit and are designed for direct integration into industrial trace heating systems

Ex-it/L: Features a high-intensity LED light for optical end-of-line status indication, enabling visual confirmation of power supply and system status—ideal for critical and remote installations
Ex-it/S: A variant without the LED indicator, offering a cost-effective solution for end termination when visual monitoring is not required

Key Benefits

Easy Integration: Fully compatible with Eltherm self-regulating heating cables
Fast Installation: Combines pipe-mounted fitting, heater grommet, and strain relief in a single unit
Visual Diagnostics: Ex-it/L allows for day and night system checks via bright LED
Robust & Reliable: Rated for harsh industrial environments with IP65 protection and -60°C to +55°C ambient operation range
Flexible Mounting: Mounts to pipes from ¾” diameter and supports insulation up to 100 mm
