Water-cooled refrigeration unit

Selection of water-cooled refrigeration units: Due to the underdeveloped domestic industry in the early days of liberation, chillers were mainly used in air conditioning units, and in state-owned enterprises, foreign brands were mostly used, so they were mainly used for civilian use. After the reform and opening up, the industry developed rapidly and the requirements became increasingly high, so various specifications of units appeared. For example, the air conditioning working condition is basically 7 degrees Celsius, but industrial use will have different temperatures, including medium high temperature, medium low temperature, low temperature, and deep cold types. Therefore, various names appeared, such as chillers, freezers, ice water machines, refrigeration machines, etc. Our company mainly produces various specifications for industrial matching, and manufacturers of various temperatures include shell and tube, water tank, titanium alloy, stainless steel, open type, split type, etc. Type, stacked low-temperature type, screw type, evaporative type, explosion-proof type, high-temperature and large cooling capacity type, Various models suitable for different locations, such as maglev, with a temperature range of 25 to minus 100 degrees Celsius, are available for customers to choose from

Water-cooled refrigeration unitMain features:

(1) The unit compressors are selected from original brands such as Copeland from the United States, Metro Compressor from France, Bizel from Germany, and Hanzhong from Taiwan for high, medium, and low temperature compressors;

(2) Use refrigerants such as R404A, R410a, R22/R407C, R507, etc. to meet cooling temperature and environmental requirements; More extensive scope

(3) Temperature selection range: We can provide process freezing media between -25 ℃ and -85 ℃ (users can choose different unit specifications with different outlet temperatures according to their production needs)

(4) According to user needs, various refrigerants (chilled water) can be selected: alcohol based refrigerants such as ethylene glycol aqueous solution, alcohol, ternary mixed solution, etc. The evaporator can also be designed according to anti-corrosion requirements and use calcium chloride aqueous solution;

(5) Designed for 24-hour non-stop operation, it can meet the cold source requirements for various continuous production processes;

(6) The unit can come with its own water tank and circulating water pump according to the cooling capacity, without the need for a cooling tower or cooling water pump, making installation and maintenance simple and convenient;

(7) Visual microcomputer control system: A comprehensive control system with visual and touch based human-machine interface operation, capable of monitoring the operation status of the unit at any time and automatically adjusting the energy output of the unit according to actual load changes. Multiple dedicated contacts and spare contacts are reserved inside the control box for users to remotely transmit lines, remotely control alarm lines, and other control lines. And it has protection functions such as high compressor coil temperature, low cold water outlet temperature, high exhaust temperature, frequent compressor start stop, abnormal voltage, etc; Control functions such as timed power on/off, operation time limit, timed power on/off, oil preheating, fault self diagnosis, fault reset, etc; Compressor exhaust temperature, ambient temperature, return water temperature, outlet water temperature, etc.
