Hot heat transfer oil and high speeds put rotary joints to a tough test. The patented DQ series was developed specifically to meet such challenges. Their mechanical seal and a cooling unit make them fit for extreme loads. By monitoring the cooling unit, malfunctions can be detected at an early stage and damage and accidents can be avoided – a big plus for operational safety. The DQ series is ideal for high-speed calenders in coating and laminating lines, paper, nonwoven, textile calenders, dryers, and rotary reactors.
At Dyrec, we are committed to empowering your business with the latest solutions. Our top-quality rotary joints are designed to optimize the performance of your equipment.

Rotary joint for thermal oil with high temperature and speed range, balance mechanical seal. DQ, DQT, DQTX with additional cooling circuit for cooling and lubrication of bearing and seal. Meets the requirements of calenders operating at high speeds and temperature. Patended system
Planned maintenance
Continuous monitoring of your rotary joints allows you to detect malfunctions immediately and take countermeasures at an early stage. The increased operational safety can have a positive effect on liability insurance.
For high temperatures and speeds
The compact and balanced mechanical seal allows use with heat transfer oil at temperatures up to 400°C.
Particularly environmentally friendly and safe
Due to the long service life and continuous monitoring of the DQ series, you avoid uncontrolled oil leaks, which benefits accident prevention and the protection of the environment.
More reliability in the production process
The mechanical seal is cooled and lubricated by thermal oil. This reduces wear and increases service life.
Extreme low maintenance
Spare and wear parts do not have to be replaced until two years after commissioning. Before that, the rotary joints does not require any maintenance.
Also with ATEX certification
For use in potentially explosive areas, we offer special versions with ATEX certification.
