The screw compressor chiller is similar to other chiller systems in that it includes components such as an expansion valve, evaporator, internal piping, controls, and refrigerant. What sets it apart, however, is its distinctive compressor.
Screw chillers utilize two helical rotors to drive and compress the refrigerant. This compression is powered by an electric motor, gas, or steam turbine, ensuring a steady flow, particularly when dealing with fluids that have high evaporation temperatures. Manufacturers who have a strong reputation in the field offer these chillers in a range of sizes, from 30 to 900 tons, allowing them to cater to various industrial cooling needs. Furthermore, they provide high-performance equipment that features reliable screw compressors from well-known brands such as Bitzer and Hanbell, reinforcing their commitment to quality and dependability.
Factors contributing to a productive chiller
A screw compressor chiller can be water-cooled or air-cooled, and your choice should depend on your process cooling needs. Air-cooled screw chillers are best for large-scale, factory-wide central, or one-to-one cooling requirements, and they come in 105KW to 928KW capacities. On the other hand, water-cooled screw chillers are available in 121 KW to 2154 KW and are ideal for medium to large-scale process cooling.
Regardless of your choice, manufacturers guarantee the following features to ensure higher productivity and reliable operations:
Branded parts – High-end screw chillers are carefully designed and built using parts from reputable brands like Bitzer and Hanbell. These compressors are proven reliable and trusted in many industries.
Excellent designs – Manufacturers guarantee outstanding system design with durable and reliable external and internal structures for stable performance. A highly knowledgeable engineering team considers factors like energy efficiency, optimized performance, and cooling capacity to create well-designed screw chillers.
Quality control – Rigorous production and quality control processes guarantee a stable and efficient screw compressor chiller. A professional team meticulously tests and verifies every part and equipment to ensure reliable performance.
Special configurations – Adding specific technologies and features can enhance the screw chiller's performance in certain industries. For instance, water-cooled screw chillers can have an integrated hydronic module, stainless medical- or food-grade steel for the water circuit, and a heat recovery module for reusing energy.
