Compressor protection measures against liquid strikes

Compressor protection measures against liquid strikes When too much liquid enters the cylinder and it is too late to discharge it from the exhaust valve, a liquid blow will occur in the cylinder. The high pressure generated during the liquid blow damages the cylinder, piston, connecting rod, etc., so it is necessary to take a Series of protective measures.

Refrigerated Air Dryer: Everything You Need to Know

If you work in an industry that requires compressed air, you know that moisture is a common problem. When compressed air is cooled, it can condense, leading to water droplets that can damage equipment, cause corrosion, and affect the quality of the final product. That's where refrigerated air dryers come in.
