Application :
In the profile and aluminium oxidation industry, the bath liquid generates heat in different sections under high frequency reaction, which gradually increases the bath temperature. When the solution temperature is higher than the process requirements, the firmness, uniformity, smoothness and surface finish of the product surface coating have a greater impact. The water cooler can help metal and non-metal ions stabilize, make metal ions quickly attach to the surface of the plated parts, increase the density and smoothness of the plated parts, shorten the plating cycle, improve the quality, reduce the loss of plating raw materials, and effectively recover all kinds of expensive chemicals, cool and maintain the constant temperature of the plating solution, which will greatly improve the production process and production efficiency.
1. World-renowned compressors: adopt world-renowned twin-screw compressor series, high efficiency 5:6 asymmetric screw tooth profile and advanced linear design, simple machine structure, only one tenth of the number of parts of piston compressor, less vulnerable parts, no suction and exhaust valves, no expansion process, large single-stage pressure ratio, insensitive to hydraulic shock. Built-in high-efficiency oil separator, the amount of oil brought out by exhaust is less than 1.5%. It can effectively improve the heat transfer efficiency of the two exchangers and save energy and durable. Efficient energy control can automatically realize 10%-100% grading or stepless energy regulation according to load variation. Through multi-head coordination and PLC control technology, the water-cooled screw chiller can achieve the best energy efficiency ratio at full or partial load, significantly reducing your operating costs.
2. Shell-and-tube condenser: using high-efficiency external threaded copper tubes, using the latest CAD/CAM design and processing technology, with CNC processing center production, corresponding to heat dissipation, water flow rate, scaling coefficient, calculating the effective heat transfer area, leaving 5-10% surplus; both end caps are easy to disassemble, easy to maintain;
3. Evaporator: The use of high-efficiency anti-corrosion evaporator, direct cooling without any secondary heat exchange equipment, energy-saving than ordinary units more than 36%, shorter refrigeration time, more accurate temperature control, truly achieve energy-saving and efficient.
4. Control system: industrial-level centralized control system, PIC controller, 7-inch touch color screen, all-Chinese operation interface, menu prompt easy to operate, can view the operation status of the unit at any time, adjust the working mode, accurately control the matching of refrigeration capacity and cooling load of the unit, ensure that the unit runs with the best efficiency and reduce operating costs. Internal integration of water flow, low temperature, high and low pressure, anti-freezing, reverse phase, delay start, overload, over-temperature, oil pressure difference and other security protection functions.
5. According to the periodic change of the rectifier, the load of the unit can be automatically adjusted, so that the temperature of the tank liquid can be accurately controlled in the range of (+1). The consistency of oxide film thickness and coloring can be ensured.
6. The unit has beautiful appearance, neat layout, compact structure, small occupied area, and is convenient for inspection and maintenance.
Special Hard Oxygen Direct Cooling Water Chiller.
