Features 1、FOR AC: Under severe cold conditions, the transmission oil inside the air conditioner may condense, which can affect the normal start up of the unit. The heating cable can promote the oil to heat up and help the unit start normally. 2、FOR COMPRESSOR: Defend the compressor from damage during cold winter and extend service life. (During cold winter, when the engine oil condenses and clumps, it can cause hard friction and damage the compressor. 3、FOR TUBE: This type of heating cable can maintain water flow when the ambient temperature is as low as ‑30 ℃. 4、SAFE TO USE: The maximum heating temperature of the cable is 70 ℃, which will not damage the pipeline; In addition, the heat cable is completely waterproof and has a double layer insulation, making you safer during use. 5、FAST HEATING: Electricity can generate heat energy and directly conduct heat conduction immediately, with high thermal efficiency that can be heated in a short period of time to achieve the desired effect. Specification Item Type: Silicone Heating Cable Material: Silicon Rubber Application Scope: Defrosting, anti freezing, warm heating, etc. Power: 45W Maximum Heating Temperature: 70 ℃ Working Environment Temperature: -30 ℃ to 200 ℃ Features: Completely waterproof, double layer insulation, integrated compression molding, simple operation, and long service life.
