1. Project Background
The client is a food & beverage manufacturer. Blow molding, packaging and filling lines all rely on compressed air, and part of the air comes into direct contact with food, requiring extremely low oil content and high cleanliness. The old piston compressors carried high oil content and unstable dew point, posing a food-safety risk.
2. Solution
We supplied an oil-free water-lubricated screw compressor with a refrigerated dryer, three-stage precision filters and a stainless steel air receiver. Food-grade piping and oil-free seals ensure oil content below 0.01 ppm and a stable pressure dew point of 2-10°C.
3. Results
Air quality now fully meets food-grade requirements and passed the client internal audit. Energy consumption dropped about 18% versus the old units, noise was significantly reduced, and the maintenance interval was extended from monthly to quarterly.
