Product Advantages

SCREW REFRIGERATION COMPRESSORS

- Rapid cooling
- The large capacity per unit reduces the quantity of compressors in largescale projects, simplifying the system.
- Efficient multilevel energy regulation can be achieved in 4-stage (25% -50% -75% -100%) mode or infinite (50% -100%) mode to meet different load requirements.
- Different compressors are selected for various operating conditions, including low-temperature, medium-temperature, and high-temperature scenarios, to meet diverse application requirements.
- Enable low refrigerant charges due to the optimised condenser and receiver design
- Energy saving, operate with environmental friendly refrigerant

SMART CONTROL PANEL

- Ready to Use: Pre-wired control panel is installed inside the condenser box or installed on the unit, just plug in and connect, ease on-site installation work

- Siemens PLC
- 7' HMI: Intuitive to understand, easy to operate
- Precision Control: refrigeration control, defrosting control
- Comprehensive Protection: compressor overload and phase loss protection, evaporator current overload protection, fault alarm, etc.
- Remote Monitoring: Including an RS485 module or WIFI module, allow users to view and modify parameters via PC or APP. It also features realtime cloud storage of refrigeration data, enabling users to easily track unit operation status at any time.

HIGH RELIABILITY & DURABILITY
- Robust design, Stable operation
- Use only high-quality refrigeration parts that are assembled with care to optimize performance
- Fusible plug or safety valves, high and low pressure protection, compressor overload protection
- Pressure testing and leak detection before leaving the factory
- Less noise and vibration
- Low failure rate, Long service life
READY-TO-USE
- Pre-wired control panel could be installed with the condensing unit (open type) or inside the condenser box (box type), just plug in and connect, ease on-site installation work
- Ready-to-use connections with shut-off valve to manually close and open
- Liquid and suction line easily accessible, with all pipes on one side
PARALLEL APPLICATION
- Improved Reliability: when a compressor in the parallel unit fails, other compressors can continue to work normally, avoiding user's heavy losses.
- Provide multi-stage energy regulation, and the unit cooling output can match the actual load demand.
- Through parallel connection, the refrigeration capacity can be expanded, the space occupied by the equipment can be reduced, and the pipeline can be reduced.
- Save equipment investment and maintenance cost, and extend the service life of the equipment.
