Features 1、WORKING PRINCIPLE: In the cold condition of air conditioning, the transmission oil condensate in the body will produce hard friction and damage the compressor, affecting the normal start of the unit. Heating belt can promote oil thermalization, help the unit to start normally, protect the compressor from damage, prolong the service life 2、PIPE FREEZE PROTECTION: This heating cable maintains water flow when ambient temperatures are as low as ‑30℃, which is a heating cable of 15mm wide and 480mm long. The power line is 1000mm long and the spring is 30mm 3、INSULATED AND WATERPROOF: The highest heating temperature of the cable is 70℃, which will not damage the pipeline; In addition, completely waterproof and has double insulators, so that can be more secure during use 4、EASY TO USE: The heating cable is molded in one body, possess long service life, simple operation, use immediately out of the box. In addition, the thermostat can be used by yourself to control the heating temperature according to demand 5、HIGH EFFICIENCY: Pipe heat cable electricity can generate heat energy, direct heat conduction, possess high thermal efficiency, can be heated in a short time to achieve the effect 6、SCOPE OF APPLICATION: Water pipe heat cable can be used in air conditioning compressor, turbine, motor, submersible pump, etc., can also be used to protect commercial and residential plastic or metal water supply lines from freezing during cold winter months(including RV, intake pipes, drains, sewers, palm trees, etc.) Specification Item Type: Pipe Heat Cable Application: Defrosting, non freezing, heating, etc. Power: 30W Maximum Heating Temperature: 70℃ Operating Temperature: -30℃~200℃ Features: Completely waterproof, double insulators, one molded, easy to operate, long service life Width: Approx. 150mm / 5.91in Length: Approx. 480mm / 18.9in Power Line Length: Approx. 1000mm / 39.37in Spring: Approx. 30mm / 1.18in Package List 1 x Pipe Heat Cable
