SRM

This pipe freeze protection heating cable is a kind of low temperature self regulating heating cable with 0.5m㎡ copper conductors .It constructed of a semi-conductive heater matrix extruded between parallel buss wires.

Usage

It constructed of a semi-conductive heater matrix extruded between parallel buss wires.It was used for freeze protection applications like our food-safe and potable water ,it can be installed inside a pipe.

Lower installation cost than steam tracing and less maintenance expense as well as less downtime.They keep the pipes ice-free without insulation, down to -40 °C.

These heating cables are highly flexible and perfect for short heating circuits.

As temperatures increase, the heater 's resistance increases which lowers the output wattage.

Conversely, as the temperature decreases, the resistance decreases and the cable produces more heat.

It can be cut-to-length according to practical requirements. It will not overheat or burnout even when overlapped.

Advantages

Automatically adjusts heat output in response to increasing or decreasing temperature.
Can be cut to length(up to maximum circuit length) with no wastage.
Will not overheat or burnout, even when overlapped.
Easy to install and maintenance.
Lower installation cost than steam tracing and less maintenance expense as well as less downtime.
Full range of controls and accessories.
No overheat or burnout even when overlapped itself.
Ready to be used in non-hazardous, hazardous and corrosive environments.

SRM is ideally used for frost protection of pipelines and other application where low temperature is needed. It is suitable for hazardous area, also non-hazardous area and corrosive area.
