This series of water-cooled screw industrial low-temperature freezers can provide-35Low temperature refrigerant at ℃ -5 ° C.The main characteristics are as follows:

1Industrial grade high-end and high standard design: water-cooled screw industrial low-temperature freezerAdopting high configuration and optimal system integration to cast high-quality products, our professional team designs according to industrial standards, with low noise and minimal vibration. Designed according to industrial standards, we are suitable for uninterrupted operation 24/7 throughout the year24Hourly operation;

2By integrating multiple innovative technologies, the product ensures high efficiency, energy saving, stability, and excellent performance

1)Innovative energy-saving technologies for economic devices:Energy saving compared to units without an economizer5%above;

2）ThePLCProgrammable control technology:Realize signal communication control for coordinated shutdown and startup of supporting equipment such as water towers and pumps,Avoid unnecessary energy loss;

3）Efficient vapor-liquid separation technology:Ensure efficient heat transfer of shell and tube heat exchangers and sufficient evaporation and heat transfer of refrigerant liquid reflux evaporator;

4）Low temperature oil cooling technology:By using low-temperature refrigerant to cool the refrigeration oil, it is then injected into the compressor to fully lubricate the moving parts inside the compressor and maximize the removal of heat generated by the motor, avoiding long-term high temperatures inside the motor and ensuring efficient, stable, and long-lasting operation of the motor and flexibility of the moving parts.

3、 Compact structure, superior performance, stable operation:

The water-cooled screw industrial low-temperature freezer uses high-quality imported twin-screw bearings, and its moving parts are only the piston compressor1/10Vibration is only present in piston compressors1/5Both radial and axial use high-precision GermanFAGAnd SwedenSKFBearing combination, combined with axial thrust balance drum, effectively balances axial load, with a failure rate only comparable to that of piston compressors1/10Combined with world-renowned control components, it ensures the long-term safe and stable operation of the unit. The condenser and dry evaporator of the unit are both equipped with high-efficiency heat transfer tubes, and the main engine uses an imported high-efficiency semi enclosed twin-screw compressor, which has a compact structure, small volume, and light weight There are many advantages such as small installation location. The semi closed twin-screw compressor has fewer moving parts, and the compressor adopts5：6Ultra efficient screw rotor, with no direct wear between rotors and high reliability. Due to the fact that the screw machine is a continuous compressor without pulsation, the unit has the characteristics of stable performance, low noise, small vibration, and smooth operation. Improved efficiency compared to reciprocating compressors20%—30%, has been obtainedIS09001International quality certification and patents from multiple European and American countries;

4、 A comprehensive energy control system:

The water-cooled screw industrial low-temperature freezer has a four stage and stepless capacity control system, energy regulation:[100、75、50、25(or activated,0Automatically adjust the start and stop of the unit according to load changes, which is more energy-efficient. During operation, the computer control system will adjust the energy output of the unit based on changes in the client's thermal load. The microcomputer quickly determines and sends a signal to push the slide valve to the required energy by monitoring the difference between the actual load measured and the user's setting. And in multiple systems, it works in an optimized way that minimizes energy consumption at the optimal cooling output, which not only demonstrates excellent performance at full load, Even under partial load, it has high operating efficiency;

5The refrigeration system operates independently:

A large capacity water-cooled screw industrial low-temperature freezer has two or more independent refrigeration circuits, even if one circuit fails/Maintenance, the other circuit can also operate normally. Equipped with backup function, especially suitable for industrial non-stop environments; ImportPLCThe human-machine interface is a LCD touch screen with graphical display, easy to operate, and available in both Chinese and English. ProvidedRS485National standard communication interface, compatible withDCSThe system is connected and can be connected to the entire factory automation network for remote control and monitoring. It is displayed in two ways: graphical and textual table parameters, which are clear at a glance;, Select the operation according to the menu on the screen, and simply touch the display button on the screen with your finger.

6、 Microcomputer programmablePLCMultiple protection functions of the controller:

Water cooled screw industrial low-temperature freezerEquipped with protection against high compressor coil temperature, timed oil preheating and power on/off, cold water flow switch, and protection against low cold water outlet temperatureY- △ Start failure protection arrange Protection functions such as high gas temperature protection, compressor overload protection, power-off memory function, frequent start stop protection, abnormal voltage protection, low oil level protection, high and low voltage protection, etc;

7Multiple protections, safe, reliable, and stable:

Water cooled screw industrial low-temperature freezerProvide comprehensive protection from refrigeration system, electrical system to water system, fully ensuring the safe and normal operation of the unit. Equipped with safety protections such as compressor motor overheating, overcurrent, abnormal phase sequence, high exhaust temperature, high pressure, low pressure, low pressure difference, freezing point, and interruption, as well as pressure control devices for the refrigeration system, the unit can operate without fail; In addition to the internal protection module of the compressor providing functions such as overvoltage, undervoltage, phase loss, and overload protection, the pressure control device of the refrigeration system can ensure that the unit works perfectly;

8Easy to install and run in a timely manner:

Water cooled screw industrial low-temperature freezerThe industrial grade low-temperature freezing dedicated testing platform ensures that all components of the unit have been installed, debugged and tested under different operating conditions in the factory, ensuring that each equipment100%Qualified factory,And refrigerant and refrigeration oil have been added, users only need to connect the waterway and circuit to put it into use, greatly reducing on-site installation and debugging time;
