The Bizelle parallel condensing unit is an efficient and reliable refrigeration system solution widely used in industries such as cold storage, food processing, and chemical engineering. The unit adopts German BITZER screw compressor, which has the characteristics of high energy saving, stable operation, and strong safety. By designing multiple compressors in parallel, the unit can dynamically adjust its operating power according to changes in cooling load, saving 20% to 30% energy compared to single machine operation. Its efficient oil separation system (with a separation efficiency of 99%) and intelligent control system (such as PLC and touch screen interface) further enhance operational efficiency and reliability. In addition, the unit has a compact structure, integrating key components such as compressor, accumulator, and oil separator, saving space in the machine room, and supporting multiple refrigerants (such as R404A, R507A, R22, etc.) to meet different temperature requirements (evaporation temperature range -65 ℃ to 5 ℃). The Bizelle parallel unit also has fault warning and automatic protection functions to ensure long-term stable operation, especially suitable for medium and large refrigeration projects.
