Eltherm Heat Tracing Cables – Frost Protection For Pipework Can Be Used in Hazardous & Non-Hazardous Areas
➡ Please note that this blog article was originally written in 2017 and was correct at the time of publish
Winter wreaks havoc and inflicts damage to process plant equipment, pipework and vessels every year if an adequate preventative maintenance plan is not in place – it is not unreasonable to expect freezing temperatures, wind chills and seasonally cold weather from October to March in the UK.

What often catches plant managers and operations out however, is not simply that exposed areas of pipework can freeze if not suitably trace heated and insulated using heat tracing cables, but actually that the more extreme weather has a physical effect on products within process equipment.
For instance, drum heaters can be deployed to provide viscosity maintenance to prevent drum contents from freezing, provide heat-up and high temperature process heating.
Against Freezing Temperatures
For many products, colder temperatures will also mean higher viscosities and whilst a well specified trace heating solution would normally cater for this and regulate working temperatures thermostatically, it is often overlooked that extreme cold snaps can actually mean that the watts per metre of heating power installed maybe insufficient to maintain a higher temperature (perhaps of 30°C or more) against an extremely sharp fall in ambient temperatures, unless this is considered up-front.
During the winter of 2010, temperatures of -17°C were recorded in parts of the UK.
Eltherm Heat Trace Frost Protection
Whilst a conventional frost protection set-up can prevent water pipes from freezing, process lines operating at higher temperatures can become blocked causing overworking to pumps and resulting in the product under process not being manufactured to sub-standard with an under-powered system.
To counter this, the process temperature should always be stated upfront and used in heat-loss calculations and not simply the frost protection level of +5°. This may sound an obvious statement, but often heat tracing installations are sub-contracted to third parties to resolve, with the ensuing ‘Chinese Whispers’ scenario resulting in a defacto frost protection solution being arrived at.
Self regulating heat tracing cables have become the cornerstone of Winterisation systems in recent years and if specified correctly will provide an effective and energy efficient solution to frost protection as well as process temperature maintenance applications in industrial and hazardous area heating requirements – it is crucial to understand that the heating cable power output decreases as the ambient temperature rises, this is the “intelligent cable” concept of self-regulating cables.
Eltherm – Heating Cables, Surface Heating Mats & Heated Hoses
Frost Protection & Hazardous Area Heat Tracing
The self regulating characteristic will mean that the power output at the intended temperature is somewhat less. It’s vital that the manufacturers trace heating cable datasheets are referred to and that the output for the trace heater cable is selected based upon the target maintain temperature and not the ambient temperature.
Another misconception is that self regulating heat tracing cables will automatically maintain a sensible frost protection level. It may well materialise this way under certain circumstances but a correctly set thermostatic line sensing controller is important to prevent water and other products in pipes from overheating.
Even a 10 watts per metre heat tracing cable if incorrectly specified can spell trouble on small pipes. For plastic pipework, we would always recommend remaining below 20W/m, whether thermostatically controlled or not. Simply put, when the trace heating cable is energised, depending on the level of the thermal insulation and the current temperature of the pipe contents, it’s not impossible to weaken pipes made from lower melt temperature plastics, for example PVC pipes.
Conversely, plastic pipes do not transfer the heat from a trace cable efficiently therefore heating cables should be over-wrapped with aluminium foil tape to improve heat dissipation to the pipework.

Thorne & Derrick have agreed a strategic partnership with RVT Group Ltd to provide Portable ATEX Fans to the UK hire market – RVT are an expert and leading supplier of Noise, Fume, Dust Ventilation, Climate Control & Hazard Monitoring Equipment Hire.
RVT have placed significant investment into the expansion of their hire fleet with the addition of both the Exstream 300 and Exstream 400 ranges of portable fans for the safe ventilation of hazardous area zones and potentially explosive atmosphere workplaces.
Exstream are the worlds first portable ventilation fans to be ATEX & IECEx certified to both electrical and non-electrical standards. Suitable for ATEX Zone 1 and Zone 2 for hazardous area ventilation.
RVT will provide a next day nationwide delivery service to site at competitive hire rates direct from their fleet – RVT will be supported by Thorne & Derrick and provide technical advice to deliver safety compliant ventilation fans to clients working in explosion risk conditions due to the presence of flammable gases or combustible dusts.
If a fan fails the risk of spark potential is huge. If the fan isn’t certified or not certified correctly the spark mitigation won’t be identified and there is an even greater risk of explosion.
24% of corporate losses is due to fire related incidents!
Everyday, there are 16 industrial explosions!
Per year globally, there are approximately:
340 million industrial accidents…
380,000 industrial fatalities…
The below images shows the catastrophic failure of an impeller on a fan which was in use within an explosive atmosphere.
90kW motor rotating at 1450rpm… Same power as a family car traveling at 70mph on the motorway!Ââž¡ RVT & T&D can mitigate any issues by supplying correctly certified and compliant ventilation fans with the safety of the end user being paramount.

This Case Application for “The Bulldog” electric heater manufactured by EXHEAT which is stocked and distributed exclusively in the UK by Thorne & Derrick, The Experts in Equipment for Explosive Atmospheres focuses on a recent application where the client required both comfort heating and additional air warming to a manufacturing facility.
Industry Sector | Aerospace & Defence
Hazardous Areas & Explosive Atmospheres
Electrical Heater Application & Benefits  | The portable electric fan heaters with ATEX Certification were selected after careful competitor evaluation to provide comfort heating to flammable workplace locations with potentially explosive atmospheres. The manufacturing bays, classified as hazardous areas, required sufficient levels of air warming to overcome low ambient temperatures and maintain labour productivity through the provision of adequate levels of comfort heating for the workforce. Additionally, the ATEX heaters will complement an aging and legacy electrical heating system which is nearing obsolescence and accelerate the curing and drying manufacturing process. The electric heaters were supplied with additional ducting to enable targeted and directed control of the air flow to improve energy efficiency and maximise the heat output.
