In the profile and aluminum oxidation industry, the bath solution generates heat irregularly under high frequency reaction, so that the bath solution temperature gradually rises. When the solution temperature exceeds the process requirements, it has a great impact on the firmness, uniformity, flatness and surface finish of the product surface coating. The water chiller helps stabilize metal and nonmetal ions, quickly attach metal ions to the surface of the plating part, increase the density and smoothness of the plating part, shorten the plating period, improve the quality, reduce the loss of plating raw materials, and effectively recover various expensive chemicals, cool and maintain the constant temperature of the plating solution, which will greatly improve the production process and production efficiency.

Compressor: double-screw compressor is adopted, with asymmetric screw tooth type and linear design of 5:6. The machine structure is simple, the number of parts is only 1/10 of the piston compressor, the number of vulnerable parts is less, no suction and exhaust valves, no expansion process, large single-stage pressure ratio, and insensitive to liquid hammer. Built-in oil separator, with oil output less than 1.5% from exhaust, effectively improving heat exchange efficiency of the reactor and the regenerator, making it more energy efficient and durable. Energy control, automatic 10% - 100% graded or stepless energy regulation according to load change. Through multi-head cooperation and PLC control technology, the water-cooled screw chiller unit can achieve energy efficiency ratio at full load or partial load, significantly reducing your operating costs.

Shell and tube condenser: the external thread copper tube is used, CAD/CAM design and processing technology is used, and the production is completed in cooperation with the CNC processing center. The effective heat transfer area is calculated according to the corresponding heat dissipation, water flow velocity and fouling coefficient, with 5-10% margin left; The end covers on both sides are easy to disassemble and maintain;

Evaporator: the anti-corrosive evaporator is adopted, and the direct cooling method does not require any secondary heat exchange equipment, which saves more than 36% energy compared with the ordinary unit. The refrigeration time is shorter, the temperature control is more accurate, and the energy is saved.

Control system: industrial centralized control system, PIC controller, 7-inch touch color screen, all-Chinese operation interface, convenient menu prompt operation, check the operation state of the unit at any time, adjust the working mode, accurately control the matching of refrigerating capacity and cooling load of the unit, and reduce the operation cost. It integrates multiple protection functions such as water flow, low temperature, high and low pressure, anti-freezing, reverse phase loss, delay start, overload, overtemperature and oil pressure difference.

Automatically adjust the unit load according to the periodic change of the rectifier, accurately control the bath liquid temperature within ± 1 ℃, and ensure the consistency of oxide film thickness and coloring.

The unit has beautiful appearance, neat arrangement, compact structure and small floor area, which is convenient for inspection and maintenance.
