DCL Supplies Electric Actuators for the World’s Largest Cooling Capacity Chiller – WLT4000RT
WLT4000RT
On November 12, 2023, McQuay delivered the world’s largest single-unit cooling capacity air conditioning system – WLT4000RT. DCL was honored to participate in this world-class project by supplying electric actuators.
The WLT4000RT is a negative pressure refrigerant centrifugal unit, measuring 13 meters long, 4 meters wide, 4 meters high, and weighing approximately 40 tons. This unit operates with low noise and offers outstanding cooling performance, achieving nearly 15% higher efficiency compared to the current international first-class energy efficiency standards.

IGV Actuator & Bypass Valve Actuator for Chiller Systems
In industrial chiller systems, DCL electric actuators has been used for IGV and bypass valves for more than 15 years. Particularly in the application of IGV actuators, DCL has accumulated over 17,000 applications and more than 15 years of reliable performance experience. These actuators are applied in various types of compressors, including single-stage centrifugal compressors, two-stage centrifugal compressors, variable frequency centrifugal compressors, and magnetic suspension centrifugal compressors.
With stable, reliable, and durable guide vane actuators, DCL ensures the continuous and fault-free operation of the core components of the chiller system.
