Industrial low temperature chiller is a kind of refrigeration equipment specially used to provide low-temperature cooling water, which is usually used in industrial and laboratory scenarios to meet special applications that require low-temperature cooling. The outlet water temperature of an industrial low temperature chiller is usually lower than that of a conventional chiller, and can reach -40°C or even lower. This equipment is designed with a special refrigerant and refrigeration system to achieve efficient and stable low temperature refrigeration.

Because of its unique process technology, industrial low temperature chiller has long been irreplaceable in the industrial field. As technology becomes more and more advanced in the future, more industry attributes with special needs will emerge, and the process will be continuously reformed and changed, all of which require refrigeration or heating for protection and blessing. In the future, the industrial low temperature chiller will not be eliminated, but its status will become more prominent. Of course, the technology must also be continuously innovated.

Features of industrial low temperature chiller

1. Compact structure and stable operation: the condenser and dry evaporator of the unit use high-efficiency heat transfer tubes, and the main engine uses imported high-efficiency semi-hermetic twin-screw compressors, which have compact structure, small size, light weight, and small installation location and many other advantages. The semi-hermetic twin-screw compressor has few moving parts, and the compressor adopts a 5:6 ultra-high-efficiency screw rotor. There is no direct wear between the rotors, and the reliability is high. Since the screw machine is a continuous compressor without pulsation, the unit has the characteristics of stable performance, low noise, small vibration and stable operation. Compared with the reciprocating compressor, the efficiency is increased by 20%-30%.

2. Perfect energy control system: The unit has a four-level capacity control system, which can automatically adjust the start and stop of the unit according to the load change, which is more energy-saving. During operation, the computer control system will change the energy output of the unit according to the change of the heat load of the client. The microcomputer quickly judges the difference between the measured actual load and the user’s setting and sends a signal to push the slide valve to the required energy. And in multiple systems, it works in an optimized way with the least power consumption at the best cooling output, not only showing excellent performance at full load, but also has high operating efficiency even at partial load.

3. Independent refrigeration cycle system: The large-capacity unit has two or more independent refrigeration circuits. Even if one circuit fails or is maintained, the other circuit can still operate normally. With backup function, it is especially suitable for industrial non-stop environment.

4. Simple and intuitive operation: The unit adopts a microcomputer programmable controller, which is displayed on the touch screen. According to the menu selection operation on the screen, the unit can be started by directly touching the display button on the screen with your finger. The screen can display the operating status of the unit at any time, and can display the parameters in two ways: graphics and text tables, which are clear at a glance.

5. Protection function of microcomputer controller:

With compressor coil temperature protection, oil preheating timing switch, cold water flow switch, cold water outlet temperature protection, exhaust temperature protection, compressor overload protection, power failure memory function, frequent start and stop protection, Protection functions such as abnormal voltage protection, low oil level protection, high and low voltage protection, etc.

6. Multiple protections, safe and reliable: In addition to the internal protection module of the compressor to provide over-undervoltage, phase loss, overload and other functions to protect the compressor, the pressure control and other devices of the refrigeration system can make the unit work foolproof.

7. Refrigeration medium: The unit uses ethylene glycol antifreeze, and can also be designed to use salt water as antifreeze according to user requirements.

8. Easy to install: The unit has completed all component installation, operation test, and filling of refrigerant and refrigeration oil in the factory. The user only needs to connect the waterway and circuit to put it into use, reducing the time for installation and commissioning.

The main application areas of industrial low temperature chiller include:

Chemical industry: In the chemical reaction process, cryogenic cooling is required to control the reaction speed and temperature to ensure production safety and product quality.

Pharmaceutical industry: Some pharmaceuticals require a low temperature environment during the production process to maintain the stability and effectiveness of active ingredients.
