Established in 1981, Greenray has been offering turbine package upgrades and maintenance to the oil & gas, power generation and waste to energy sectors for more than 30 years. Greenray's primary focus is on supporting legacy rotating equipment which have typically been installed for over 25 years.

More recently the Greenray Group has the ability to offer new package solutions, including the elements required for control and monitoring of the package. Greenray has become one of the key players in the oil & gas, power generation and waste to energy sectors and continues to deliver the highest level of quality and technical competence in providing world class engineered solutions.

In 2015, The Greenray Group further enhanced its product offering to its customers, by forming ‘Greenray Control Solutions Ltd’, an entirely separate and dedicated division which offers advanced engineering control solutions to owners and operators of gas turbine, steam turbine and associated driven equipment on a worldwide basis. The dedicated team of engineers have global experience of designing and implementing modernisations and control upgrades which improve the availability of the equipment and can include remote monitoring solutions.

Greenray Control Solutions Ltd works together with our other operating divisions, Integrated Turbine Systems Ltd and Greenray Turbines (Lincoln) Ltd in providing a complete range of services and products across a wide range of rotating equipment. Having recently completed work for a major utility company in the UK, Integrated Turbine Systems is leading the way in its field focusing on Steam Turbines and Turbo Solutions.
