Radial housing connection. ATEX certification optional. Five drain holes in housing, can be blocked with plugs in dusty environment.
Possible Applications
This rotary joint is specifically deployed in industrial heating and temperature control systems where thermal oil serves as the primary heat transfer fluid. Typical integration points include the rotating cylinder journals of industrial calenders, laminating lines, and heat-setting machinery used in textile and film processing. It is engineered to maintain a reliable fluid boundary on high-speed rotating rolls, preventing thermal degradation of the sealing faces during continuous high-temperature operation. The compact one-way flow configuration and balanced mechanical seal arrangement make it particularly well-suited for manufacturing equipment requiring precise web temperature uniformity and dependable leak-free sealing under continuous thermal stress.
