制冷设备市场的快速发展、大型的低温冷库、制冰设备、速冻设备越来越多，对于氟利昂活塞式压缩机已经很难满足这些设备的需要，本公司的低温半封闭低温螺杆冷凝机组可满足于-40℃～25℃的需要，可使用于较大的低温制冷设备中使用。
该系列产品具有如下特点：
       ● 采用比泽尔低温螺杆压缩机，具有效率高、寿命长、震动小、噪音低等特点；
       ● 机组配置齐全，主要制冷配件及控制元件均可靠性高；

       ● 机组具有压缩机反转、过热、过载、排气温度、低油位油及系统高低压等多种安全保护，确保运行的可靠性；
       ● 机组带有经济器运行，大大提高了低温工况运行时的制冷量；
       ● 具有多级能量调节，可适应于不同冷负荷的变化，有效降低能耗。

With the rapid development of the refrigeration equipment market, there are more and more large-scale low-temperature cold storage, ice making equipment, and quick freezing equipment. It is difficult to meet the needs of these equipment for Freon piston compressors. Our company's low-temperature semi enclosed low-temperature screw condensing units can meet the needs of - 40 ℃ to 25 ℃, and can be widely used in larger low-temperature refrigeration equipment.
● This series of products have the following characteristics:
● Using a German Bizel low-temperature screw compressor, it is characterized by high efficiency, long service life, small vibration, and low noise;
● The unit is fully equipped, and the main refrigeration accessories and control components are world-famous brands with high reliability;
● The unit has a variety of safety protection such as compressor reverse rotation, overheating, overload, exhaust temperature, low oil level and high and low pressure of the system to ensure the reliability of operation;
● The unit operates with economizer, which greatly improves the refrigeration capacity under low temperature conditions;
● With multi-level energy regulation, it can adapt to changes in different cooling loads, effectively reducing energy consumption.
