Neil Malone, the founder and owner of Heat Trace Limited, has authored a proposed specification for electric trace heating
The specification entitled “Safe Electric Trace Heating at Optimal Cost – SPECIFICATION + PHILOSOPHY” will be of value to all electrical design engineers, specifiers and students of electric trace heating.
The founder is keen to emphasise that it follows his personal approach to trace heating design, which was influenced by his lifetime involvement in the development and maintenance of trace heating standards.
As such, it is intended as an impartial, unbiased document that mentions neither his company nor its products. Instead, it refers only to generic products.
The main thrust of his philosophy is that temperature safety - the major challenge - will be most effectively provided by inherently temperature-safe self-regulating heaters, which do not have to rely on temperature controls.
Optimal Cost will result when ambient sensing proportional temperature control is provided alongside inherently temperature-safe self-regulating heaters. This is because fewer circuits are possible with ambient proportional control. Such controls are only appropriate if the heating cables are inherently temperature-safe, which many are not.
