Condensate Management

Reduce oil concentrations in compressor condensate - KOWS Series Oil-Water Separator Units

Compressed air systems are a critical industrial utility—but they also generate condensate as a byproduct of lubrication and heat dissipation within the compressor. This condensate contains a mixture of oil and water and is classified as hazardous industrial waste. Even a single liter of oil can contaminate up to one million liters of water, creating significant environmental and regulatory risk.

To address these challenges, oil-water separation is not optional—it is a legal requirement in many regions. The KELTEC KOWS Series Oil-Water Separator Units provide a dependable, cost-effective, and environmentally responsible solution. Designed in accordance with ISO 14000 standards, KOWS units reduce oil content in compressor condensate from typical levels of 300–500 ppm to below 10 ppm, allowing facilities to discharge wastewater safely, legally, and with confidence.
