Inherently Temperature-Safe cables are cables that have no significant output at their withstand temperature. More

The maximum temperature a heating cable can be exposed to before it is damaged. Sometimes referred to as maximum exposure temperature or design temperature

The surface of the heating cable must not exceed the maximum temperature of the constructional materials or the Termperature Classification if installed in a hazardous area. This is ensured by limiting the pipe or workpiece temperature to a safe level either by design calculation or by means of temperatue control devises.

Constant Wattage cables do not regulate they have the same output irrespective of pipe or surface temperature

Industrial Applications

		Freeze Protection of Pipework				Process Temperature Maintenance
		In cold climates, water, chemical, or other process pipework often needs to be heat traced to prevent freezing				Heating and maintaining process pipework, storage tanks and vessels at the correct temperature
		Above Ground Long Pipelines (up to 5 km)				Long Buried Pipelines (up to 5 km)
		In the context of electric heat tracing design, a long pipeline is usually any pipe from 500 metres to many kilometres in length				The heat tracing of long buried pipelines is an application in which Heat Trace Limited have unique experience
		Long Distance Pipelines (up to 50 km)				Tanks and Vessels
		Very long pipelines, up to 50km in length can be heated from a minumum number of supply points using Skin Trace heating systems				Heat tracing is applied to tanks and vessels to prevent freezing, or to ensure products are stored at the correct temperature.
		Internal Pipe Tracing				Instrument Pipes
		Intertrace is used to internally heat pipes where external tracing is impractical. Such situations may include				Instrument and sample lines need to be maintained at optimum temperatures to ensure correct data analysis
		Control and Monitoring
		It is true today that with the right control, a heater can be made to do virtually anything required of it. Heat Trace can provide simple ON/OFF control, or state of the art micro-processor control and monitoring systems, linked to plant SCADA and DCS systems
