Water cooled screw chiller description |
The water-cooled screw chiller is a cooling system composed of a screw compressor, condenser, evaporator, expansion valve, and electric control system. Primarily used for air conditioning in various settings like office buildings, schools, and canteens, it relies on water for cooling. To ensure optimal performance, it requires a matching cooling water circulation system, such as large cooling water towers. Using clean water helps prevent scaling and corrosion, which can compromise cooling efficiency and increase maintenance costs. The refrigeration system features high-quality piping, valves, and accessories, ensuring effective sealing to prevent refrigerant leakage and maintain cooling efficiency.
Features of the water cooled screw chiller |
●Suitable for 0~45℃ ambient temperature: The screw type water cooled chiller utilizes water for heat dissipation. In extremely low temperatures, freezing of the cooling water can damage pipes, pumps, and other components, impacting the refrigeration system's operation. To prevent freezing, anti-freezing coolant or insulation measures can be applied to the cooling water pipes.
●High-quality raw materials: The water screw chiller incorporates top-grade condensers, expansion valves, evaporators, and electrical control components, guaranteeing optimal equipment performance and longevity. The expansion valve, for instance, ensures precise control of refrigerant flow, preventing issues like inadequate sealing or clogging that could affect equipment performance.
●Refrigeration capacity: With a range of 128kW to 545kW, Kassel offers customizable solutions tailored to customer requirements.
●Advanced control features: The equipment boasts a high-precision, large-screen touch screen with multi-language display and remote control capabilities, enhancing usability and control for operators.
