Connecting the electric vehicle industry
For electric vehicles (EVs) to reach their global breakthrough, charging must become more accessible, faster and more efficient. The higher output generates more heat and that requires effective thermal management. Liquid cooling fulfils the cooling requirements and quick couplings help facilitate the installation, reliability and maintenance.

Connecting the data center industry
Cooling for data centers is undergoing a huge change. The increasing demand for cloud, AI, IoT and edge applications is driving the requirement for increased cooling capacity. Liquid cooling can meet the capacity while also being more energy-efficient and cost-efficient. Investing in liquid cooling is an investment in future requirements.

Connecting the semiconductor industry
The need for smaller and faster semiconductors has rapidly increased over the past decades, not least within the developments of IoT (Internet of Things), 5G, AI, and the automotive sector. With that, thermal challenges arise. Efficient liquid cooling with high-precision equipment is needed for safe and reliable semiconductor manufacturing. Quick connect couplings with high-flow capacity and no spill upon disconnection will enable quick and easy installations and smooth maintenance operations.

Connecting the maritime industry
When extreme pressures are combined with extreme applications, such as high-pressure hydraulic bolt tensioning on marine ship engines, safety must be the utmost concern. Use of service tools in two strokes low-speed engines onboard, staff needs to be able to trust the equipment and that they can carry on their job in a safe and efficient way. CEJN has world-leading competence in high-pressure hydraulic equipment and offers a variety of solutions for safe operations onboard.

Connecting the fire and rescue industry
When taking part in a difficult rescue operation, whether dealing with a major car accident or serious conflagration, you have to put your trust and people’s lives in the rescue equipment at your disposal. It needs the capacity and power to cut through any material. When entering a burning house, you should not have to worry about your breathing apparatus but be free to focus on the mission, save lives and put out the fire.
