What semi-hermetic screw compressors are customers willing to pay for? In the early years, many people felt that semi-hermetic screw compressors are expensive and have high technical threshold. Without semi-hermetic piston compressors, they are cheap and easy to use and maintain, so they are a bit daunted. With the transformation of the market, the user experience has been upgraded, and some large and medium-sized new projects or old ammonia warehouses are more inclined to semi-closed screws. As a professional ice skating venue, ice skating hall is the core of ice making. Bitzer CO2 compressor and Bitzer built-in variable frequency screw compressor are used to provide strong power for the system, which also makes the ice making process more energy-efficient and efficient. , Relative indirect cooling can save about 300,000 kWh per year. Of course, there are still many application cases of Bitzer, which are not listed one by one. For common refrigerants such as R134a and R22, the application range of Fusheng screw compressors is from the lowest temperature of -65℃ to the highest temperature of 80℃. Under low temperature refrigeration, the FS single-machine bipolar screw compressor is used in food quick-freezing and freeze-drying equipment. High temperature drying can use CSR AHH single-stage screw or stand-alone bipolar high temperature heat pump compressor, and can also be used for cold and heat dual effect. At present, in addition to food freezing, the petrochemical industry needs explosion-proof applications. FS also uses CSR-EX series products. The current market trend is mainly low-temperature refrigeration, which has a lower threshold and the people take food as the sky, so the future growth trend The demand for large-displacement low-temperature screw compressors will surge, and the market demand for single-machine, two-stage, high-efficiency screws will show a substantial increase as the market demand increases. In addition, there are many screw compressors that have attracted more and more "high-quality powder" due to their advantages of energy saving, power saving, and high cost performance.
