Product Details

Our air-cooled screw-type chilled (hot) water units offer outstanding performance for diverse applications. The screw compressor technology provides high efficiency and reliable operation, ensuring a steady supply of chilled or hot water. In cooling mode, it delivers powerful refrigeration to meet the demands of large commercial spaces, industrial facilities, and more. When switched to heating mode, it warms water effectively, catering to heating needs. The air-cooled design eliminates the need for complex water cooling systems, simplifying installation and maintenance. With intelligent controls, operators can easily monitor and adjust settings, guaranteeing optimal comfort and productivity in any environment.
