Key features include:
1. Industrial-grade high configuration and high standard design:Utilizing high-configurations and optimized system integration to cast high-quality products, our professional team designs with industrial-grade standards, ensuring low noise and minimal vibration. Designed to industrial standards, it is suitable for continuous 24/7 operation throughout the year.
2. Integrates multiple innovative technologies, ensuring high efficiency, energy-saving, stability, and exceptional performance of the product:
1) Innovative energy-saving technology for economic devices:The water-cooled screw-type low-temperature chiller with an economizer is more energy-efficient by over 5% than one without.
2) PLC Programmable Logic Controller Technology:Achieve联动 control of start/stop signals for equipment like water tower pumps, minimizing unnecessary energy loss.
3) High-Efficiency Gas-Liquid Separation TechnologyEnsures efficient heat exchange and refrigerant liquid回流 evaporation in the shell-and-tube heat exchanger, as well as complete evaporation and reheat in the evaporation unit.
4) Low-Temperature Oil Cooling TechnologyCools the refrigeration oil with a low-temperature refrigerant, then injects it into the compressor to fully lubricate the internal moving parts and maximize the removal of heat generated by the motor, avoiding long-term high temperatures inside the motor. This ensures the motor operates efficiently, stably, and has a long service life, as well as the flexibility of the moving parts.
3. Compact structure, superior performance, and stable operation:
Utilizing high-quality imported twin-screw bearings, the moving parts are only 1/10 of those in a reciprocating compressor, and the vibration is only 1/5. Both radial and axial components are equipped with precision German FAG and Swedish SKF bearing combinations, along with an axial thrust balancing drum to effectively balance axial loads, resulting in a failure rate just 1/10 of that of a reciprocating compressor. Combined with world-renowned control components, the unit ensures long-term safe and stable operation. The unit's condenser and dry evaporator both use high-efficiency heat transfer tubes, and the main unit is equipped with an imported high-efficiency semi-hermetic twin-screw compressor, offering advantages such as compact structure, small size, light weight, and minimal installation space. The semi-hermetic twin-screw compressor has fewer moving parts, employs a 5:6 ultra-high-efficiency screw rotor, and has no direct wear between rotors, ensuring high reliability. As it is a continuous compressor without pulsations, the unit features stable performance, low noise, minimal vibration, and smooth operation. Its efficiency is 20% to 30% higher than that of reciprocating compressors, and it has obtained ISO 9001 international quality certification and patents in multiple countries in Europe and America.
4. Comprehensive Energy Control System:
Water-cooled screw-type low-temperature chillerEquipped with a four-level or stepless capacity control system, energy regulation: [100, 75, 50, 25 (or start, 0%)], automatically adjusts the unit's start/stop based on load changes for greater energy efficiency. During operation, the computer control system adjusts the unit's energy output according to the client's thermal load changes. The microcomputer quickly judges and sends signals to push the throttle to the required energy by monitoring the difference between the actual load and the user's settings. Moreover, in multi-unit systems, it operates optimally with the least electrical energy consumption at the best cooling output, demonstrating excellent performance not only at full load but also at partial load, ensuring high operating efficiency.
5. Refrigeration system operates independently:
High capacityWater-cooled screw-type low-temperature chillerEquipped with two or more independent refrigeration circuits, ensuring that even if one circuit fails or requires maintenance, the other can operate normally. Features a backup function, particularly suitable for continuous industrial operation environments; the imported PLC human-machine interface is a liquid crystal touch screen with graphical display, easy to operate, with both Chinese and English options available. Equipped with an RS485 national standard communication interface, it can be connected to a DCS system and integrated into the entire factory's automated network, facilitating remote control and monitoring. It displays information in both graphical and tabular text formats for easy understanding; operations are selected via the screen menu, and the display buttons can be directly touched with a finger.
6. Microcomputer programmable PLC controller with multiple protection functions:
Overheat protection for compressor winding, preheating oil timer on/off, cold water flow switch, low outlet temperature protection for cold water, Y-△ start failure protection, overpressure protection for exhaust gas, overload protection for compressor, power failure memory function, frequent start/stop protection, abnormal voltage protection, low oil level protection, high/low pressure protection, etc.
7. Multi-layer protection for safety, reliability, and stability:Offer comprehensive protection for systems ranging from refrigeration to electrical and water systems, ensuring the unit operates safely and reliably. Equipped with safety features such as overheat protection for compressor motors, overcurrent, phase sequence errors, excessive exhaust temperature, high pressure, low pressure, low pressure differential, freezing point, and open circuit, the pressure control devices of the refrigeration system guarantee the unit operates without fail. In addition to the compressor's internal protection module offering over/under voltage, phase loss, and overload protection, the pressure control devices of the refrigeration system further ensure the unit operates flawlessly.
8. Easy to install and operate for immediate use:
Industrial-grade water-cooled screw-type low-temperature chiller dedicated test platform ensures that all components are fully installed, different operating conditions have been debugged and tested at the factory, guaranteeing each unit's performance.Water-cooled screw-type low-temperature chillerFactory-certified, pre-filled with refrigerant and lubricating oil; simply connect the water and electrical lines to be operational, significantly reducing on-site installation and commissioning time.
