Screw point unit features：
◆The unit consists of high, medium and low temperature series, which can meet the refrigeration system with evaporation temperature of 10 °C ~ -40 °C or lower.
◆The unit type includes screw single unit and screw parallel unit, which can meet the needs of various refrigeration systems.
◆The unit adopts Germany Bitzer, Taiwan Hanzhong or Taiwan Fusheng semi-closed screw compressor, which has the characteristics of high efficiency, long life, low vibration and low noise. The unit can realize multi-level energy regulation or stepless energy regulation, which can be applied to different cooling load changes and effectively reduce energy consumption.
◆The unit is fully equipped, and the main refrigeration components and electrical control components are all well-known brands with reliable performance.
◆The electronic control system has a high degree of intelligence. It adopts the microcomputer controller to automatically control and accumulate the running time at regular intervals to realize the rotation of the compressor.
◆The electronic control system has various safety protections such as phase loss, overheating, overload, undervoltage, exhaust temperature, oil temperature, low oil level, oil flow and high and low pressure of the system to ensure the reliability of operation.
◆ The medium and low temperature unit is equipped with an economizer to greatly improve the operating efficiency of the system and reduce the operating cost.
◆The unit is compact and highly integrated, which greatly saves the space of the machine room and is very convenient to install and operate.
◆The unit refrigerants R22 and R404A are optional, and the compressors of a single parallel unit can be connected in parallel up to seven units.
