Product Description

Self regulating heating cable for process temperature maintenance

    In a centralized hot water supply system,water in distribution pipes may cool down when not used in room. Hot water will not be available until the cold water is drained in the distribution pipes. It takes quite some time for hot water to come if the distribution pipe is too long, affecting comfort and convenience on one hand and causing waste of energy and water resources on the other.    

    To keep the water hot in the distribution pipes, appropriate heat preservation measure should be in place. Considering the costs of installation and maintenance of heat preservation systems and timeliness of heat preservation, the use of self-regulating heat tracing cable is an ideal choice as it regulates temperature automatically and can be cut in lengths according to specific need. It's only necessary to keep the heat tracing cable in full contact with the pipelines and secure it with heat tracing accessories and then protect with heat insulation materials. The heat tracing system will then be able to keep water warm in the pipelines. Meanwhile, it can regulate heat output subject to temperatures of each section of pipeline.

    Sanniu's heat tracing systems can effectively address the heat preservation issue of centralized hot water supply systems and can save energy and water resources. It can be widely used in hotels, high rank residential areas, government buildings, kindergartens and other places where centralized hot water system is in place.

Product discription

Summary
Self-regulating heating cable is constructed of a semiconductor heater and two parallel bus wires with the addition of insulation layer, The heating elements are parallel to each other and its resistivity has a high Positive Temperature Coefficient "PTC". It has the characteristics of automatically regulating the temperature and output power when heat; It can be sheared to use and overlapped by itself without the problems of overheat and burnout.

Working Principle
In each self regulating heating cable, circuits between the bus wires change with the ambient temperature. As temperature decreases, the resistance decreases which produces more output wattage; Conversely, as temperature increases, resistance increases which lower the output wattage, loop back and forth.

Features 
1. Energy efficient automatically varies its power output in response to pipe temperature changes.
2. Easy to install, can be cut to any length (up to max circuit length) required on site with no wasted cable.
3. No overheat or burnout. Suitable for use in non-hazardous, hazardous and corrosive environments.

Applications
1. Processing of agricultural and sideline products and other applications, such as fermentation, incubation, breeding.
2. It applies to as all kinds of complicated environment such as ordinary, danger, corrosion, and explosion-proof areas.
3. Frost protection, ice-melting, snow-melting and anti-condensation.
