With electrical heating cables and products for applications that range from melting ice on pipes to preventing pipes from freezing and de-icing pavements to warming underfloors, Easyheat has a product or solution for most applications.
Pipe freeze protection cables from EasyHeat are used to protect water supply and drain pipes from freezing and ultimately bursting which can result in large areas of damage and serious financial implications.
EasyHeat offers safe and reliable heat trace cable products that are easy to install and reliable. The product range includes:
Heating Cables
EasyHeat SR Heat Trace Cable Installation
EasyHeat SR heating cable provides an effective solution to cold weather related problems. From preventing pipes from freezing to removing ice build up in drains or gutter pipes, SR cable is engineered to alter its heat output as the surrounding temperature changes. As the the temperature gets colder the cable gets hotter.
SR heat trace cable is available in power densities of 3, 5 and 8 watts per foot, all heat trace cables are UL listed and can be supplied in 120 volt and 240 volt supply ratings.
The benefits of self regulated heat trace cable are that there is no wasted power as the cable automatically adjusts to the ambient temperature and as soon as that temperature has been reached, the cable powers-off meaning that only the exact amount of energy needed is ever used. SR cable is available in cut-to-length and pre-terminated kits making installation easier for cable installers.
An Introduction To EasyHeat AHB Electric Freeze Protection Cables
EasyHeat Self Regulating Trace Heating Cable
EasyHeat SR heat trace cable is constructed from a special irradiated self-regulating core with a TPE inner jacket, copper ground braid with moisture and UV resistant over jacket. When the outside temperature drops, the cable core has many conductive paths that generate electric heat to keep the water flowing in the pipe.
As the surrounding temperature increases, there are fewer conductive paths and therefore less heat is generated meaning the trace heating cable uses the exact amount of energy needed.
As the cable is self-regulating, it can be wrapped over itself if required when installed on pipes, flanges or valves. Other key benefits of EasyHeat SR heat trace cable include:
EasyHeat self-regulating trace heating cables are an effective solution to cold weather and frost problems in both residential and commercial applications providing freeze protection to water pipework for all winter conditions down to -40°C.
EasyHeat cables and accessories are typically used for frost protection, temperature maintenance and melting ice on roofs. Specially designed EasyHeat kits provide the correct hardware for properly installing SR trace self-regulating heating cables.
Each connection kit contains detailed instructions for connecting the cable to power supplies and other heating cables. There are many industries in which heat tracing cable is used and for many applications – the most common industries include petrochemical, oil and gas, refineries, pharmaceutical and power generation.
In applications, where pipes are exposed to cold temperatures such as petrochemical plants in colder climates, trace heating cable is commonly used to prevent liquid from freezing or to maintain viscosity.
Thermal insulation alone is incapable of preventing pipework freezing and therefore pipes must be heat traced to guarantee frost protection.
Nelson Heat Trace Cables: Suitable For Hazardous Area Locations.
Established in 1951, EasyHeat are today part of the Emerson industrial automation group of companies. Emerson Industrial offer the most trusted and innovative products for power generation, electrical protection, power quality, industrial heating, precision cleaning and materials joining.

ATEX Gas Detectors
Crowcon gas detectors and detection equipment is available in fixed or portable type. Simply, fixed gas detectors protect plant; portable gas detectors protect people.
Gas detectors are used globally throughout many industries that regularly face the threat of hazardous gases – their range of gas monitors and devices can protect against leaks and the presence of toxic and flammable gases. There are many commonly occurring gases that can cause a threat to life and infrastructure if undetected including carbon dioxide, methane, sulphur dioxide, hydrogen sulphide, copper sulphate and carbon monoxide.
These gases have varying effects on the human body where some are undetectable by humans as they are odourless and colourless, others can have devastating effects within seconds and must therefore be detected immediately.
By deploying portable or fixed gas detectors, companies can ensure the safety of their workforce, prevent unnecessary damage to their equipment and reduce any down time.
Crowcon Gasman – Portable Single Gas Detector Monitor, displaying gas concentration with audible, visual and vibrating alarms.

T4 gas detector is designed for use in industries such as the oil and gas sector, water and waste treatment facilities, utility companies and steel processing plants.
Gas leaks and exposure to gas can be extremely harmful and be the catalyst for devastating accidents resulting in great loss of life and damage to property. By detecting gases early and taking steps to prevent their release, these dangers can be averted.
In many industries where classified hazardous areas exist, gas can often be the main cause of incidents if it is accidentally ignited. Throughout the oil and gas, petrochemical and offshore marine industries, gas detection is absolutely vital with both portable and fixed units often used in conjunction for gas monitoring and detection and hazardous areas Zone 1 and Zone 2.
Typical gases detected by Crowcon detectors include:
