Drainage device for the food industry BEKOMAT® 12

Overview
The BEKOMAT® 12 is an electronic condensate drain for compressed-air systems. It uses an integrated capacitive sensor for volume-controlled discharge to minimise compressed-air losses while ensuring reliable removal of condensate in industrial applications.

Features

• Integrated capacitive sensor for volume-controlled condensate discharge to minimise energy consumption and avoid compressed-air loss.
• Aluminium housing; CO versions feature hard coating and glass‑bead blasting for oil-free or aggressive condensates.
• Near-zero compressed-air loss during discharge thanks to electronic level control and pilot/solenoid sequence.
• Easy installation and maintenance with service-concept models enabling quick unit exchange.
• Suitable for wide industrial use: automotive, food & beverage, pharmaceutical, general manufacturing.

Detailed product information
The BEKOMAT® 12 family provides automatic, volume-adaptive condensate discharge without significant loss of compressed air. The capacitive sensor monitors the liquid level and, when a preset level is reached, the control triggers a pilot/solenoid sequence that vents the space above the diaphragm to allow discharge while minimising air loss. CO variants include additional surface protection for oil-free or aggressive condensates.
