Renewable Energy Fluid Swivel and Transfer Solutions

header

Dynamic Sealing Technologies (DSTI) provides fluid swivel and electrical slip ring products for a range of renewable and alternative energy applications. We offer integrated solutions to help our global customers achieve their project goals, from design and manufacturing through to testing and qualification.

DSTI field-proven fluid rotary union and swivel joint products are utilised worldwide to provide efficient, consistent and reliable connections for high-speed, high-temperature and high-pressure applications.

DSTI has developed and implemented proven systems and processes to deliver fluid product solutions for complex and challenging alternative energy projects.

Fluid rotary unions for wind turbines

Today's leading wind turbine manufacturers demand reliable hydraulic blade pitch control systems. DSTI's fluid rotary unions provide dependable supply and return hydraulic power to the blade actuators, operating continuously in the toughest environments and conditions.

With more than 2,000 blade pitch control rotary unions in service, DSTI's field-proven designs deliver the highest performance both onshore and offshore.

Additionally, DSTI's fluid rotary unions can also be integrated with electrical slip rings to provide positioning sensor data and fibre-optics.

Fluid swivels for parabolic trough solar field piping systems

Designed for high temperatures and high pressures, DSTI's swivel joints provide rotational movement to heat transfer fluid (HTF) collector piping in parabolic trough concentrated solar power (CSP) systems. Used in conjunction with flexible hoses, DSTI's swivel joints reduce the risk of system fluid leaks - requiring less maintenance and the need for replacement parts.

DSTI's swivel joints offer the latest technology being developed in next-generation CSP systems, delivering a solution that can absorb the rotations and axial motions of today's largest parabolic troughs.

Rotary unions for hydroelectric turbines

Designed for high speed, DSTI's fluid rotary unions provide dependable supply and return hydraulic power to the blade actuators for adjusting pitch to adapt to flow conditions for hydroelectric / water (Kaplan) turbines.

Integrated with electrical slip rings and positioning sensors, DSTI's rotary joints can provide precise and reliable position feedback in addition to fluid transfer.

ISO 9001:2008 accreditation and customer support

DSTI conducts its operations to ensure that its staff work together and take responsibility for the health and safety of themselves and others, to minimise its impact on the environment and ensure the best quality in products and services. Our international ISO 9001:2008 management system demonstrates strictly applied standards with an innovative approach to continuous improvement.
