Solar water heater, as a new and mature hot water device, has been widely used for its environmental protection and energy saving. At the same time, it faces a difficult problem. The low temperature in winter leads to freezing and blocking of solar energy pipelines, or even pipeline rupture, resulting in unnecessary losses and waste. For this problem, the current common method is to empty the solar energy pipeline in winter, which is inconvenient for people to use solar energy normally. And the special heating cable for solar pipeline can help you solve this problem.
The special heating cable for solar energy is composed of three parts: wire, PTC conductive heating material, and insulating layer. It is a self-limiting temperature heating cable. The core part is made of nano-conductive material and high molecular polymer, which is evenly extruded on two parallel metal wires, and cross-linked by irradiation. It has the advantages of automatically adjusting the heat tracing temperature, free cutting, no high temperature overheating, easy installation, and convenient maintenance. It is an effective solution to solve the freezing block of solar energy pipelines.
At the same time, according to the difference of the minimum ambient temperature in different regions, the electric heat tracing of solar pipelines is divided into DWL-a, A, B, C, D and other models with a minimum temperature distribution below zero: 15, 20, 30, 35, 40. According to Choose suitable heat tracing products for different ambient temperatures to help you effectively solve the problem of freezing and blocking of solar pipelines in winter.
