Quick coupling solutions for Wind
Safe and reliable quick coupling solutions facilitate both the manufacturing, installation, maintenance and operation of wind turbines. High-pressure couplings are ideal for secure bolting and non-drip couplings will help to provide an efficient liquid cooling solution.
This is how quick couplings help improve wind turbine maintenance, operation and manufacturing
- Efficient and safe bolting with ultra high-pressure hydraulic quick couplings
- Hydraulic quick couplings for installation, maintenance and blade pitch control
- Non-drip liquid cooling quick couplings enable pre-filled parts to help reduce onsite maintenance and production down-time
- Efficient manufacturing using compressed air tools and high-flow safety couplings
Ultra High-Pressure Bolting Solutions
Wind turbines are subject to extreme conditions and vibrations. Large wind turbine installations consist of more than 20,000 bolts that need to be exactly tightened using hydraulic bolt tensioning tools to reach specified bolt loads. With ultra-high-pressure hydraulics, we refer to extreme pressures from 700 to 4000 bar, which may be required for some specific bolt tensioning operations. Pressures at those levels should be taken seriously and always carried out with the highest regard for safety. Safe bolting, whether on land or offshore, using CEJN quick connect couplings to power hydraulic bolt tensioners makes the job quick, safe and efficient.
Examples of bolting applications include:
- Foundation
- Tower
- Nacelle
- Blade connections
- Internal components
A safe workplace for everyone
Bolting operations in the tight space within the wind turbine are potentially dangerous. You must trust the tools at hand. Ultra-high-pressure hydraulics up to 4000 bar put significant stress on each component.
CEJN high-pressure hoses and quick couplings are widely used and acclaimed for their high level of safety and performance. The quick couplings include unique safety features like the safety alert ring for connection verification and the safety lock to secure the connection. Hoses can be equipped with CIS for hose kit safety inspection both on and off the field to verify the quality of your equipment. These features make the CEJN quick couplings and hose kits for ultra high-pressure the ideal choice for safe bolting in confined spaces like wind turbines.
T-connections simplify simultaneous connections
T-connections help simultaneous connections for bolting using single port bolt tensioners. Old porting block solutions can be replaced with a single, leak tested and ready-to-use component minimizing the risks of leakage.
It is compact and, thanks to a modified seal, the valve in the nipple can handle dynamic load while disconnected without the risk of seal damage. This means that it is safe to have a disconnected nipple at the end of a serial connection and there is no need for plugged couplings.
"We use high-quality products, so the service technicians can do their job more efficient and in a safe way"

Hydraulic products for reliable operation and efficient maintenance
CEJN hydraulic products offer robust design and features that will benefit the overall system in wind turbines. The ability to connect under high hydraulic pressure makes maintenance and installation more convenient eliminating the need for de-pressurizing the hydraulic system.
By integrating CEJN couplings, operators can ensure reliable performance while significantly reducing downtime and enhancing overall turbine efficiency.
CEJN has a large assortment of hydraulic components for the installation and maintenance of the hydraulic system in wind turbines:
- TLX for blade pitch control system and connection with residual pressure
- Press-check nipples for all hydraulic power packs
- X-series couplings with pressure eliminator for hydraulic fluid filling
- Multi-X multi-couplings for gearbox removal eliminate the risk of cross-connection
- X-series couplings for grease components
- WEO hydraulic plug-in fittings for maximum flexibility and vibration resilience

Quick couplings for liquid cooling maximizes power generation
Time and money-saving benefits of quick couplings in the liquid cooling system of wind turbines:
- Pre-filled liquid cooling manifolds for quicker on-site maintenance and increased production up-time
- Vibration resistance to secure the cooling circuit during long periods of operation.
- High-efficiency quick couplings with low pressure drop for a more efficient cooling system that requires a lower pump pressure
Save money on maintenance with pre-filled cooling modules
With wind turbines getting bigger to increase power output, the amount of heat generated from frequency converters and electronic control systems have passed the border of what conventional air cooling can manage. For the largest wind turbines, liquid cooling is necessary to keep the electronics in safe and operational temperature.
Using quick couplings, service technicians can work with pre-filled cold plates and just exchange them on the field to minimize turbine downtime and do the maintenance off-field while the turbine is producing.

Improving safety and efficiency in Wind Power production
Wind power manufacturing requires high efficiency compressed air tools for grinding, cutting, sanding and polishing. The easy interchangeability and the high power output of tools in a compressed air system makes it ideal for wind power manufacturing. Tool efficiency depends on the airflow and anything that limits the airflow will lower the overall tool performance. Optimizing the compressed air system by spotting and tightening existing leaks and change old couplings to modern high-flow safety couplings will have the potential to increase both productivity and performance.
- High-performance quick couplings increase performance and safety
- Safety-tested and quality-approved hoses and quick couplings for breathing air
- Safety hose reels with high visibility hose to avoid tripping accidents
- OSHA-approved compressed air blowguns
Connecting the manufacturing industry
Cutting production costs and increasing productivity are always hot topics. The search for new and improved methods and/or products is always a priority. CEJN recognizes the manufacturing industry as a place where small investments can generate big savings by simply examining the pneumatic, fluid, or hydraulic system. With more than 30% of all compressed air produced just to compensate for leakages, there are substantial amounts of energy and money to be saved.
