The chilled water infrastructure needed reliable flow regulation to ensure consistent performance across the facility's extensive heating and cooling systems.

                To meet these requirements, the system incorporated two key Griswold Controls products: QuickSet Brass Valves and 3” to 24” Wafers with Automatic Flow Limiting cartridges.

                These components provide precise flow management while simplifying installation and ensuring long-term reliability across the facility’s HVAC infrastructure.

                Benefits and Outcomes

                The integration of Griswold Controls products helped ensure the facility’s HVAC infrastructure operates efficiently despite the significant scale of the manufacturing complex.

                With accurate flow control and dynamic pressure compensation, the system maintains optimal operating conditions throughout the facility. This improves reliability, enhances energy efficiency, and reduces operational costs.

                These improvements contribute to a highly efficient manufacturing environment capable of supporting one of the most advanced solar module production facilities in the world.

                Products Used

                Two specialized Griswold Controls solutions were used to ensure precise flow control and optimal HVAC performance throughout the facility.

                QuickSet Brass Valves

                QuickSet Brass Valves are manual balance valves designed to provide precise and accurate flow control. Featuring a durable brass body and stainless steel stem, these valves include a memory stop that allows the valve to return to a preset flow rate after shut-off.

                3” to 24” Wafers with Automatic Flow Limiting Cartridges

                3” to 24” Wafers with Automatic Flow Limiting cartridges maintain balance in HVAC systems regardless of pressure fluctuations by dynamically controlling flow within ±5% of the design specification.

                The scale of this project is notable—Griswold Controls rarely supplies valves as large as 24 inches, yet ten of these large valves were required for this installation.
