Electric Heat Tracing Cables from Bellis Australia

Electric heat tracing is the application of heat to pipes, vessels, tanks, instruments and associated equipment to offset heat loss due to lower ambient temperature. Trace heating can be applied through several processes like electricity, glycol, hot oil, and steam. Electric heat tracing is a specific field of technology used for freeze protection (Winterization), to reduce product viscosity, prevent condensation and maintain the plant's production operations.

There are numerous industries where electric heat tracing can be used. The following are the possible applications for heat tracing or better known as electric heat tracing:

Refinery and Petrochemical Process Plant
Cryogenic and Liquefied Natural Gas terminals
Power Generation Plant
Mobile Tank Container Heating System
Rail Heating System
Building and Construction

The science and effectivity of electric heat tracing rely greatly on high-quality heating cables. These heating cables are considered to be the vital component of an electric heat tracing turnkey solution.

Constant Wattage Heating Cables with Resistance Wire
Constant wattage heating cables are designed for maintaining temperatures of up to +150°C or 302°F. The heating cable is equipped to withstand heat tracing in industrial refrigeration or in places with harsh climates. It is used for frost protection and temperature maintenance of pumps, vessels, pipelines and valves.

Constant wattage heating cables are flexible in nature - they can be easily cut to the required length off the roll, with the assurance of having a constant power output throughout the cable's length. It is easy to assemble and install as connecting cable isn't necessary and input can be unilateral.

Some of the advantages of using Constant Wattage Heating Cables are the following:

Easily cut off from the roll
Long life cycle
UV and chemical resistance
Single end power input
Constant power output

Self-Regulating Heating Cables
Self-regulating heating cables are the most common parallel constructed heating cable. It incorporates two bus wires that are surrounded by a semi-conductive polymer matrix that contains high carbon content. Using a self-regulating heating cable eliminates the risk of hot or cold spots. As the temperature changes, the polymer expands and the distance between carbon particles also increases. This leads to an increase in the resistance and decreased watt output. When the temperature drops, the whole process is reversed and watt output increases.

Self-Regulating Heating Cables have the following benefits:

Various temperature range applications
Easy to assemble and install
Can be cut off to the desired length
Self-regulating with adjustable output
Chemical resistant

Mineral Insulated (MI) Heating Cables
Mineral insulated heating cables are highly robust, mechanically stable, moisture-proof and non-flammable. They are suitable to use in applications where high wattage output and operating temperatures are required, like in the chemical and petrochemical industries. These heating cables are suitable for heating pipes, vessels, tank containers, flanges, valves. Mineral insulated cables can even be used in floors or concrete walls.

The following are some of the benefits of Mineral Insulated Heating Cable:

Chemical resistant
Airtight seal metal sheath
Moisture-proof and can be immersed in fluids
High operating temperatures with high watt output per meter
