Series water-cooled screw type low-temperature chiller is a high-performance and mature low-temperature freezing product which is researched, produced and sold by our company. The liquid outlet temperature is optional from - 45 ºC ~ 0 ºC, and the refrigerating capacity is optional from 15000 kcal / h to 950000 kcal / h. This chiller integrates the characteristics of many other products. It adopts a special semi closed screw cryocompressor or two-stage compressor, assisted by high efficiency heat exchanger technology, control technology and optimal system configuration matching. It adopts a microcomputer controller, which makes the chiller have the characteristics of compact appearance, reasonable layout, convenient use and maintenance. Users only need to connect the pipeline and station of the water system The required power supply can be put into operation. This series of water-cooled screw type low-temperature water chiller is widely used in new materials, environmental protection waste gas recovery, chemical industry, biomedicine, research and development, ultra-low temperature cooling source and other industries. The manufacturing technology of this product is mature and the operation is stable and reliable. At present, it has won the favor and recommendation of customers.
1. Superior performance:
The main engine adopts the international advanced semi enclosed screw compressor, motor and compressor integration, without the consideration of shaft seal leakage; two compressors or multiple compressors have start-up and shutdown cycle control procedures, which can prolong the service life of each component of balanced load; two compressors or more adopt multiple refrigeration circuit, one of which must be maintained, the rest of the circuit can still operate normally, water-cooled screw The water-cooled screw type low-temperature water chiller compressor is started by unloading and depressurizing to avoid the impact on the power grid.
2. Easy to install:
The water-cooled screw type low-temperature water chiller has compact structure, small floor area and space saving of machine room; when leaving the factory, it has been strictly debugged and completed, and has completely reached the field use state; the water-cooled screw type water chiller The vibration is very small, the foundation does not need vibration isolation measures, and the installation is simple; only the evaporator chilled water and condenser cooling water pipes need to be connected during the installation; the operation and maintenance cost is low; the water-cooled screw chiller can implement intelligent program control according to the demand of load: 100%, 75%, 50%, 25% (or startup), 0,
3. Energy saving;
The total number of compressor parts of water-cooled screw type low-temperature water chiller is only 1 / 10 of that of reciprocating type, with simple structure, few vulnerable parts, no inlet and outlet valves, insensitive to humidity stroke, and very low failure rate; the failure free operation of screw compressor can reach 40000 hours; Shanghai water-cooled screw type water chiller Complete safety protection functions; pressure protection: high voltage protection and low voltage electrical automatic protection device; motor protection: under voltage protection, phase loss protection, reverse phase protection, overload protection, motor overheating protection; oil shortage protection: antifreeze protection: when the temperature of the chilled water is too low, the water-cooled screw chiller Automatic shutdown; safety valve protection: when the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open. All kinds of protection of the above equipment make the water-cooled screw chiller safe and stable operation; screw compressor features; high efficiency and good reliability with imported high-efficiency fluorine-resistant motor from France; the latest generation 5-6 asymmetric tooth shape; four stage capacity regulating continuous unloading capacity control system of water-cooled screw chiller; supporting German fag and Sweden SKF high-precision bearings; sval effect Oil separator; low vibration and noise.
4. Microcomputer control
German "Siemens" PLC programmable touch controller, the human-machine interface of water-cooled screw chiller is displayed in Chinese: Italian "Carel" text display; water-cooled screw chiller automatically monitors the temperature of cold water outlet, controls the slide valve through PLC, regulates the compressor, and effectively tracks the field use load; the display is intuitive and clear, water-cooled screw chiller Display all water temperature points and operation time in operation directly, and make it clear at a glance (PLC); automatically record and save the fault alarm and occurrence time of the latest water-cooled screw chiller, and send out fault handling prompt; correct the original content according to the actual needs (by secret code). Such as the location of inlet and outlet water temperature, volume regulation, protection points, pressure, etc. Operation status display (PLC), animation display of operation status, including compressor operation, refrigerant flow status, water flow status and temperature display; convenient to fully understand the operation status of low-temperature chiller.
5. Refrigeration original device / electrical original device.
In the electrical control system and refrigeration system of the water-cooled screw type low-temperature chiller, the main components such as relay, thermal protector, expansion valve, pressure controller, drying and filtration are world famous products, which greatly improves the reliability of the whole water-cooled screw type low-temperature chiller.
6. Industrial platform professional test:
The platform ensures that all parts of the unit have been installed, commissioned and tested under different working conditions in the factory, and that each equipment is 100% qualified for delivery, and has been filled with refrigerant and refrigeration oil. Users only need the connection of water and circuit to put it into use, which greatly reduces the installation and commissioning time on site;
