- Long circuit lengths up to 200 metres or more
Short lengths up to 1 metres - Latest technology backed by group resources
Locations in hazardous or non-hazardous areas. - System is waterproof for overload or buried pipelines.
- Easy to install
Approved by recognized inspection agencies like C.C.E Nagpur & tested by CMRS , Dhanbad
CFH are rugged enough to withstand rough handling, yet flexible and easy to install.
Trace Heating System For Long Pipelines.

CALGEN traces are multi-stranded nichrome wire insulated with PTFE to give high temperature rating and weather proofing braided with glass yarn for efficient heat transfer and H type varnish coating . Ideally suited for fuel pipelines carrying Furnace/LSHS/Post FCC oils/Other viscous oils in process pipelines/storage tanks.
CALGEN electrical heat tracing is a process of applying heat to the external surface of tank/pipe to maintain specific temperature of the contents.
Advantages For Electric Tracing Over Steam Tracing
COST: Electric tracing system is very much cheaper than steam tracing .Pipes,fittings & system used for steam generation not necessary for electric tracing. Hence saving factor of 40% to 50%
EFFICIENCY: heat loss in electric tracing is negligible over steam tracing due to its high insulation.
COST OF MAINTANANCE: Maintenance cost of electric tracing is almost negligible since there is no corrosion, leakage & pollution when compared to steam tracing.
INSTALLATION: Electric tracing system can be installed very easily when compared to steam tracing

Calgen Heating Jackets

These are purely custom built to suit specific requirements. These heating jackets find applications in maintaining temperature in reactor vessels for easy flow of fluid while handling road tankers, Ice prevention & icing in radar reflectors, aircraft propellers and Nose Cones.
These are easy to install at low cost. These can withstand exposure to high temperature and are compatible to common voltage. And, at the same time they are economical.
Heating jackets consist of an inner layer of glass cloth in which heating elements are stitched. This is provided with 2” thick glass wool insulation and a final outer covering of PVC coated glass cloth. High flexibility of the jacket enables very good contact with the surface to be heated providing good heat transfer and high efficiency. Eyelets and laces arrangement on it enables quick and easy installation and dismantling.
Silicon Rubber Heat Tracer

Silicone Insulated Heater
Wire Does your business or product need reliable, accurate, steady temperatures for specific tools and equipment? Silicone insulated heater wire is ideal for fast heating speed, even temperature, and accurate, efficient heat that is resilient to outside environments. This kind of wire can be applied in many different ways in a variety of equipment:
- Industrial applications: electric machines, air conditioning compressors, submersible pumps, freezing protection equipment, etc.
- Medical equipment: developmental tube heater, bodybuilding cloth, electric medicine pad, waistband, blood analyzer heater, etc.
- Household items: rice cookers, refrigerators, hairdressing and beauty tools, electric chairs, etc.
- Other applications include greenhouses and other planting and breeding businesses.
Silicone insulated heater wire is used in high wattage settings, with a min., of 15 watts per foot. With an electrical grade fiberglass core and SW-200 silicone rubber insulation, this wire is dependable and efficient. Among the varieties of silicone insulated heater wires, most wires can handle temperature ratings between 150 degrees Celsius and 200 degrees Celsius, from 600 through 6,000 voltage ratings. Voltages range between 300V and 600V. The diameters of the wires vary from 1.6 mm to 8 mm. all insulated heater wires last for over 10,000 hours. When one need a steady temperature in an area that naturally creates high, unsteady temperatures, choose silicone insulated wires. These wires are flexible and resist heat because of the silicone insulation that keep connections working.
