Product Configuration
The silicone rubber crankcase heater belt is a heating device specially designed for cooling the crankcase of the compressor, its main function is to provide the necessary heat for the crankcase in a low temperature environment, so as to avoid the "liquid knock" phenomenon that may occur when the compressor is started. The so-called "liquid strike" means that the liquid refrigerant is reverted back to the compressor during the operation of the system and mixed with the lubricating oil, resulting in the dilution or even failure of the lubricating oil. This situation will not only affect the normal operation of the compressor, but also may lead to serious mechanical damage.
In order to better understand the role of the silicone crankcase heater belt, we need to understand the working principle of the compressor and the importance of lubricating oil in it. Compressor is one of the core components of the refrigeration system, responsible for the low temperature and low pressure refrigerant gas compression into high temperature and high pressure gas, so as to promote the entire refrigeration cycle. In this process, the lubricating oil plays a key role in lubrication, cooling and sealing. However, at low temperatures, if the lubricating oil temperature in the crankcase is too low, the liquid refrigerant may migrate to the crankcase and mix with the lubricating oil, reducing the viscosity and performance of the lubricating oil, and thereby affecting the stability and life of the compressor.
The silicone rubber crankcase heater heats the crankcase evenly, ensuring that the lubricating oil is always maintained within an appropriate temperature range. This heating method can effectively prevent the migration of the liquid refrigerant, while ensuring that the viscosity and flow of the lubricating oil are not affected. In addition, the compressor crankcase heater belt is usually designed with energy saving and safety factors in mind, such as adopting thermostatic control technology to avoid overheating, or using corrosion-resistant materials to adapt to different working environments.

Product Features
✅ Prevent Liquid Strike
the refrigerant dissolves easily in lubricating oil at low temperature, and the heating belt evaporates the refrigerant to avoid liquid entering the cylinder when starting.
✅ Keep the oil temperature
ensure the lubricating oil viscosity is appropriate to reduce wear.
✅ Reduce starting current
When the cold machine starts, the low oil temperature may cause the load to increase, and the preheating of the heating belt reduces the starting impact.
Product Application
In practical applications, silicone compressor crankcase heaters are widely used in a variety of refrigeration equipment, including household air conditioners, commercial freezers, and industrial refrigeration systems. The installation of compressor crankcase heating belts is particularly important for equipment that needs to operate for a long time in cold climates. The crankcase heater can not only improve the reliability of the compressor, but also extend the overall service life of the equipment, thus bringing higher economic benefits to the user.
