Automatic Electric Heat Cable Concrete Underfloor Heating Cable Frost Protect Heating Cable

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.

1. How much electricity is consumed per hour? Consider an average room size of 100m2 . The heated area is approximately 80%, or 80m2 .In the case of the 150W mats, when the heater is ON, the hourly consumption is 1500W times 80m2.When the recommended thermostat is turned on, take 100m2 as an example. The room is filled with heat about 20min~30min, which is between 450W and 750W.Of course, the specific cost depends on your electricity consumption and electricity unit price. 2. Do I use insulation materials? We recommend that you use insulation materials. On the one hand, it is for your safety considerations, on the other hand, because it can lock the heat, the preheating will be faster, and the power consumption will be reduced. 3. Is it safe to use in a humid place? Yes, our products are of high quality and have a grounding wire. 4. How long is the warranty time? 25 years for heating cable & heating mat.2 years for for constant wattage/self-regulating heating cable and thermostats. 5. Can I crop it? Yes, you can crop the grid 6. What is the thickness of the cable?The cable is 3.5mm thick. 6. What is the thickness of the cable? The cable is 3.5mm thick.
