Introduction
    Yu Jiang water cold condenser uses fully-closed or semi-closed air compressors of imported famous brands. The highly effective condenser, evaporator, cooling and controlling components are of the famous brands. They are calculated and tested accurately to produce the most superior and reasonable design. The machine is tested at the running test center and only launched when achieving the technical specification. Therefore, this machine has high efficiency, good quality, and low incident rate. Regardless of its use for preserving, cool keeping, chilling, quick chilling, our company can design and manufacture upon required temperature of customers, providing the best products to customers.

Working principles
    Water cold condenser uses water as refrigerant. The high temperature, high pressure gaseous refrigerant escaping from the air compressor output goes through the tubular condenser and cooling tower for chilling to form a low temperature-high pressure liquid refrigerant, then expansion valve supplies low temperature low pressure liquid refrigerant to ventilator for evaporation. The high quality ventilator blows cold wind to achieve chilling efficiency.
The high-quality condenser with cooling ventilator, smart controller, high quality temperature controller, defrost timer can control precisely the temperature in warehouses and defrosting temperature. It performs the functions of preserving (-2℃ to +8℃), cool keeping (-10℃ to -23℃), cooling (-23℃ to -30℃), quick cooling (-30℃ to -80℃)

Air compressor 
    Air compressor : uses fully-closed or semi-closed air compressors of globally famous brand-names such as  COPELAND, BITZER, MANEUROP, HANBELL, high chilling efficiency, stable operation, power saving, low incident rate, convenient maintenance.
(Air compressor uses refrigerants such as R22、404c、R407c、R134a)

Tubular condenser and winged evaporator
    Condenser: uses various heat exchange copper tubes imported or produced domestically. The copper tube’s outer surface is processed in low-level ladder shape, thereby increasing the heat exchange area, enhancing the heat transfer, keeping the best chilling condition for the machine, and increasing machine longevity. The copper tube’s inner surface is glossy, thereby reducing water pressure and making it easy for cleaning and maintenance.
    Cold ventilator (evaporator):uses various heat exchange copper tubes imported or produced domestically. The internal thread high effective heat exchange copper tube and corrosion-resistance aluminum winged expand the mechanical tube so as to join the copper tube and aluminum pad to promote optimally the heat transfer efficiency and make it easy for cleaning and maintenance, effective combination with the ventilator to increase the efficiency of the cold ventilator.

Cooling unitss
    Cooling unitss use global well-knownl brands such as DANFOSS ,ALCO,SPORLAN, with first-rate quality and superior functionality which helps promote machine efficiency.

Electric control-system
    Electric control-system uses smart PLC、PC touch screen control system in Chinese language with quick response and precise control. The system has functions of water temperature automatic control and record of incident causes. The operation is simple and easy. Its automatic protection function can prevent the machine from damage during operation.

Protection devices 
    Overload protection devices of air compressor, over heat protection devices of coiler, overload protection devices ventilator engine, protection devices of low-high pressure switch, phase protection devices (opposite in phase, phase shortage), protection devices of anti-freezing, safety valve or safety bolt.
