Ultra High-Pressure at Work During Wind Power Installations

Installing turbines for wind power requires ultra high pressure for accurate bolt loads. Turbines are usually installed in remote areas: on mountain tops, in the countryside or out at sea where conditions can be tough. Hence the need for high-performance tools during installation and subsequent maintenance work. With 40 years of experience in producing ultra high pressure couplings and hoses, CEJN has always focused on safety, delivering quality of the highest order for a safe work environment and fast installation.
