Screw compressors are a type of rotary compressor that use two interlocking helical rotors to compress gas. They are highly efficient, reliable, and capable of continuous operation, making them ideal for industrial applications. These compressors are commonly used in refrigeration, air conditioning, and gas compression systems due to their ability to handle high volumes of gas with minimal vibration. Additionally, screw compressors are known for their low maintenance requirements and long operational life.
