The integrated water-cooled screw type low-temperature industrial refrigeration unit is a professional industrial low-temperature process chilled water integrated system launched by Nuo Leng Company. It does not require users to assemble and match the system on site, and can be put into use by simply connecting the supply and return water pipes and power supply.
The unit adopts Siemens intelligent control system from Germany. Users only need to set the corresponding data according to the process chilled water requirements, and the unit can automatically operate.
The integrated water-cooled screw type low-temperature industrial saltwater refrigeration unit mainly has the following characteristics:
1) Superior performance of compressor
Adopting a 5:6 semi sealed twin-screw compressor, there is no shaft seal leakage, and the motor and compressor are in the same shell.
The balanced operation of each head of the unit ensures that multiple heads are started and stopped according to their operating time, with priority given to starting the head with the shorter operating time, achieving balanced operation of each head and ensuring longer service life of each component;
Each machine head serves as a backup for each other. Multiple independent refrigeration circuits are used for multiple compressors. In case one circuit needs maintenance, the other circuits can operate normally, achieving mutual backup between each machine head;
When multiple compressors are started and stopped using star delta or variable frequency, they are all unloaded and stopped step by step or loaded and started step by step according to the pressure reduction of each compressor head, reducing the instantaneous impact on the power grid.
2) Intelligent control system
The unit adopts Siemens programmable PLC and color touch display screen, and the control panel screen of the unit adopts full Chinese display;
Real time monitoring of operational data will read the supply and return water temperature, pressure, and flow rate of each device in the integrated machine in real time, accurately control the cooling water temperature of the unit, and directly display the various water temperature points and operating time during operation
come
Real time adjustment of operating load by detecting data to adjust the load or start stop control of multiple compressors, ensuring the end load demand;
The memory storage function of the chiller records real-time data and fault alarms during the operation of the unit, making it convenient for users to maintain and query. When a fault occurs, the unit will automatically issue a fault prompt alarm message;
3) Each refrigeration component and electrical configuration of the unit
The refrigeration components selected for the chiller unit include expansion valves, drying filters, shut-off valves, pressure gauges, solenoid valves, pressure controllers, etc., all of which are made of high-quality international and domestic brands. The electrical system is equipped with thermal relays
The equipment, contactors and protectors, intermediate relays, power switches, etc. are also made of high-quality international and domestic brands, effectively improving the quality and operating life of the unit, making the chiller unit safer and more reliable during operation.
4) Security protection measures
The unit is more complete in terms of safety protection, with more comprehensive protection functions, including compressor overheating, overpressure and overload protection, power supply voltage instability protection, such as undervoltage, overpressure, phase loss, unit high and low voltage protection
Antifreeze protection, insufficient refrigerant oil protection, overcurrent protection, etc
5) Convenient on-site installation
The integrated chiller unit has completed the integrated assembly of various components and supporting equipment in the factory, with a more compact unit structure, more reasonable pipeline optimization, smaller equipment footprint, and energy-saving installation location for users;
After the overall assembly of the unit is completed according to the user's requirements, systematic debugging is carried out to ensure that the unit fully meets the user's usage needs before it can be shipped out of the factory;
After the integrated unit is transported to the user's site, it only needs to be connected to the supply and return water pipelines, the power supply of the unit, and can be put into use conveniently and quickly.

The integrated water-cooled screw type low-temperature industrial refrigeration unit is selected and configured according to the actual needs of customers, ensuring safer and more stable use for users. At the same time, our company provides 24-hour comprehensive service.
