Mechanical Instrumentation Asset Solutions

When you need reliable, efficient, compliant solutions to help you operate, maintain, and protect all your rotating and non-rotating assets, Nexus Controls can help. All of our Mechanical, Instrumentation, and Control (I&C) Solutionshave been built to exacting, high-quality standards to match and exceed OEM specifications. Whether you require a solution for hydroelectric energy applications, steam turbines, gas turbines, or mechanical and dynamic controls, our global engineering team will work with you to seamlessly integrate, build, and install our products into your existing plant infrastructure while complying with your applications’ global standards. In short, your requirements are our top priority.

For over a century we have designed and successfully implemented mechanical and I&C systems for a variety of applications including turbines for hydroelectric power, steam turbines, gas turbines, wind turbines, nuclear power applications, boiler-furnace systems, oil & gas systems, and more.

To help you manage your assets while meeting compliance requirements for your turbine's overspeed protection, hydraulic or electric actuation, we offer both standard and custom solutions. When you have a specific application that needs monitoring, our time-tested instrumentation panels can help, enabling you to leverage the knowledge gained from our extensive global installed base. This proven approach ensures that we will successfully deliver an integrated solution that uniquely meets your needs.

When you’re ready to modernize your Mechanical and/or Instrumentation and Control systems, we stand ready to help you design a solution that fits your specific requirements, budget, and installation schedule. The Nexus nTrinsic portfolio complies with global technical regulations and standards (e.g., API, ASME, IEC, IEEE, CE, UL, CSA, CCC, EN, ISO, etc.) for the industrial, utility, hydroelectric energy, and petrochemical vertical markets so you can be sure that your equipment and processes are in full compliance.

The Nexus Controls portfolio of Control Systems, Industrial Cybersecurity, Mechanical, I&C products, and comprehensive Services enables our international team of domain experts to provide turnkey solutions.

Nexus Controls nTrinsic portfolio helps global customers optimize turbine overspeed protection, reduce maintenance costs, and decrease your risk of potential downtime. We offer solutions to maintain legacy systems as well as modernize your aging systems while keeping your plant operational and efficiently maintained.

In 2000, Nexus Controls purchased from The Woodward Governor Company their entire hydroelectric powerplant business, including hydroelectric generators, mechanical control solutions, and dynamic controls solutions. As a result, Nexus Controls is the sole legal owner of all legacy Woodward Governor Hydro intellectual property (IP), data, and original engineering drawings. Nexus Controls can maintain, service, repair, or replace any damaged or worn-out OEM mechanical equipment.
