Advantages of Low Temperature Chillers

1. Compact structure and stable operation: the condenser and dry evaporator of the unit all adopt high-efficiency heat transfer tubes, and the host adopts imported high-efficiency semi-hermetic twin-screw compressor, which has the advantages of compact structure, small volume, light weight and small installation position. and many other advantages. The semi-hermetic twin-screw compressor has few moving parts, and the compressor adopts 5:6 ultra-high-efficiency screw rotor. There is no direct wear between the rotors, and the reliability is high. Since the screw compressor 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 automatically adjusts 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 and sends a signal to push the spool valve to the required energy by monitoring the difference between the measured actual load and the user’s setting. And in multiple systems, working in an optimized way with the least power consumption at the best cooling output, it not only shows 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/maintains, the other circuit can operate normally. With backup function, it is especially suitable for industrial non-stop environment.

4. Simple and intuitive operation: The unit adopts microcomputer programmable controller (PLC Chinese or English display), touch screen display, select operation according to the menu on the screen, directly touch the display button on the screen with your finger to start the unit. The screen can display the running status of the unit at any time, and can display parameters in two ways: graphics and text tables, which are clear at a glance;

5. The protection function of the microcomputer controller: it has the protection of the compressor coil temperature is too high, the oil preheating time switch, the cold water flow switch, the cold water outlet temperature is too low protection, the start failure protection, the exhaust temperature is too high protection, the compressor Overload protection, power failure memory function, frequent start and stop protection, abnormal voltage protection, low oil level protection, high and low voltage protection and other protection functions;

6. Multiple protections, safe and reliable: In addition to the internal protection module of the compressor, which provides functions such as overvoltage and undervoltage, phase loss, overload, etc. to protect the compressor, the pressure control devices of the refrigeration system can make the unit work foolproof.

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

8. Easy to install: The unit has completed the installation of all components, running tests, and filled with refrigerant and refrigerating oil in the factory. The user only needs to connect the water circuit and the circuit to put it into use, which reduces the installation and debugging time.
