HB ProductsModel HBOC/C -Oil Level Controller for Compressors

SHARE
The HBOC/C is an advanced oil level controller specifically designed for compressors, aiming to ensure optimal performance in various industrial settings. It excels in detecting and maintaining oil levels, mirroring its predecessor, the HBSO, but with enhanced capabilities. Its integrated controller precisely manages oil levels by controlling valve operations, facilitating efficient filling or emptying processes based on the application's requirements. This device is especially suitable for gas environments where precise oil management is crucial for operational efficiency. The HBOC/C's versatility extends across different compressor systems, making it an indispensable tool for maintaining equipment reliability and extending service life through effective lubrication management.
