The Optimum-DW series chillers, equipped with a twin-screw compressor and an 8-step capacity control (12.5% to 100%), have been developed for processes that require high capacity. They are preferred due to their significantly smaller footprint compared to air-cooled devices. Additionally, they are designed for indoor applications, allowing for cooling to take place closest to the process, ensuring optimal efficiency and minimal loss in cooling. The components used in this series of devices are selected to be top-of-the-line, keeping up with advancing technology. Thanks to the high capacity control, there is no need for an inverter. Our Optimum-DW series chillers, mainly used in HVAC projects, are manufactured within a capacity range of 342 to 2662 kW.
