How It Works in a Trace Heating System

In a trace heating system, the ELAK-Ex-R acts as the central hub for electrical connections. Heating cables (self-regulating or constant wattage types) are routed through this junction box to connect with power supplies and control sensors. The box facilitates:

• Power distribution to trace heating circuits
• Sensor integration for temperature monitoring (using Pt100 sensors)
• Connection protection against environmental factors and electrical hazards

By ensuring safe, organised, and compliant connections, the ELAK-Ex-R is essential in maintaining the integrity and efficiency of heat tracing in pipelines, tanks, valves, and more.
