According to the working conditions, open drive screw condensing unit can be divided into Z and D series. Z series machine can be widely applied in high temperature warehouse, or used as cold source in cooling system of pharmaceutical, chemical and food industry. D series units can be widely applied in cold storage and IQF machine, and can also be used as cold source of low temperature process cooling system in pharmaceutical, chemical, food and other industries.

Technical Parameters

Features
1. Compression ratio of the screw condensing unit is adjustable, which is suitable for various working conditions.
2. A stepless speed regulation of energy can be achieved.
3. With a high precision oil separator, the oil separation efficiency is up to 99.9999%.
4. The oil cooler has a high heat transfer efficiency and small volume.
5. The oil filter has a high filtration accuracy and low resistance.
6. With the best structure design, the machine has a small size and is easy to install.
7. The high efficiency condenser has a high utilization with heat exchange area.
8. The motor is directly connected with the compressor, allowing a high efficiency.
9. D series adopts secondary air-in compressor so the refrigerating capacity can be increased by 20% at low temperature.
10. Perfect safety protection.
