What fluid is necessary in a package industrial screw compressor for cooling, lubricating, and sealing the rotors?

In a package industrial screw compressor, a silicone-based fluid is recognized for its effective cooling, lubricating, and sealing properties necessary for the operation of the rotors. Silicone-based fluids have unique thermal stability and a wide operating temperature range, making them particularly suitable for high-performance applications like screw compressors. Their chemical structure allows for effective lubrication, which reduces friction and wear between the rotating parts. Additionally, these fluids have excellent sealing properties that help maintain pressure within the system and prevent leaks, enhancing the compressor's efficiency.

The other types of fluids, such as water-based fluids, mineral oils, and petroleum-based fluids, might not offer the same level of performance in all aspects required for screw compressor applications. Water-based fluids, for example, may not provide adequate lubrication at higher operating temperatures, while mineral and petroleum-based fluids can break down under extreme conditions, leading to potential failure of the compressor components. Thus, the unique properties of silicone-based fluids make them a superior choice for maintaining optimal compressor function.
