About Deublin

DEUBLIN is a leading manufacturer of rotary joints in the field of industry and renewable energy sources.

A rotary joint is a mechanical device that allows fluid under pressure to be transferred from a stationary source to rotating parts of devices such as cylinders, cylinders, tables, spindles or drives for the purpose of heating, cooling or transmitting hydraulic power.

Based on several decades of experience in performing demanding rotary joint applications, Deublin has also developed electric slip rings that include operation in demanding environments. Long-lasting slip ring technology ensures constant and reliable operation without the need for maintenance.

All Deublin products are 100% tested before being offered to customers and are manufactured using state-of-the-art manufacturing processes.
