• Belimo Innovative Water Test Lab

    Designed to meet LEED Gold standards, Belimo Americas’ Danbury, Connecticut headquarters was constructed from the ground-up using some of the most innovative green building techniques on the market today. The facility also incorporates many of our very own energy-saving products and puts them on display so that visitors can see how they are being used in real-world applications. LEED for Building Design and Construction (LEED BD+C) provided us with the framework for building our holistic green facility and allowed us to maximize its sustainability by taking full advantage of the benefits provided by our innovative line of products.


    Belimo Americas innovation team located in Danbury designs, develops and tests products for actuated valves. The team provides innovative solutions by leveraging both internal and external supplier knowledge. They demonstrate excellence in project management and provide manufacturing engineering support for valves, actuators, and sensors made within our production facilities in Danbury and Sparks, Nevada. The team is continuously revolutionizing the Belimo range of control valves and actuators to include new products and technology innovations offering superior performance, reliability, and energy efficiency within HVAC control system.

    Belimo state-of-the-art HVAC water test lab located in Danbury is one of the most extensive facilities in the HVAC industry with over 15,000 square feet, which enables Belimo to deliver the most innovative, highest quality products. Our performance testing provides assurance to our customers that they’ve made the right decision by choosing Belimo. Flow testing includes equal percentage curves, pressure independent curves, and rangeability. Shell testing is performed for threaded and flanged valves up to 5,000 psi. Automated systems for flow testing improve accuracy, precision, repeatability, and efficiency. Our lab’s flow testing capacity is 8,800 GPM, with the largest pump capable of providing 5,600 GPM.

    Our durability testing involves subjecting valves to 100,000 cycles at worst-case temperature and differential pressure. We have the capacity to test over 240 valves ranging from DN10 to DN450, with a maximum media temperature of 302°F (150°C). With 21,000 GPM durability testing capacity, we could fill one Olympic size swimming pool every 30 minutes or one standard above-ground pool every minute. We also perform Long Life testing, where the valve is subjected to application conditions for months at a time.

    Belimo’s performance testing verifies that our products comply with industry and trade association specifications, including ANSI, UL, EN, IEC, ISA, MSS, and VDI/VDE. Our testing is performed with ISO 9000 traceability.

    Belimo knows the importance of innovation, and the water test lab plays a vital role in delivering world-class products at the highest level of quality. At Belimo, we continuously invest in our infrastructure, ensuring it is well positioned for the future needs of our customers and the HVAC industry.
