Introduction
    Yu Jiang wind-cold turbine low temperature cooling machine uses fully-closed turbine air compressor. This imported product has famous brands. The new highly efficient condenser, evaporator and cooling and controlling components are of the most famous brands globally. Their temperatures can reach -35℃. This cooling machine has good features such as superior functions, stable performance, simple operation, compact structure, good appearance, regardless of using ethylene glycol or brine. The required temperature is 0℃ ~ -35℃. Our company can design and manufacture according to customer requirements. The averagely low temperature turbine cooling machine produced by our company is calculated and tested with the accuracy to create a superior and reasonable design. It is tested at the running test center and only launched when achieving the technical criteria. Therefore, this cooling machine has high efficiency, good quality, few problems, providing customers the best products.

Working principle.
    Wind-cold turbine low temperature cooling machine uses water for cooling. The high temperature, high pressure gaseous refrigerant escaped from the air compressor output goes through the winged condenser and heat dissipation ventilator for cooling to form a low temperature-high pressure liquid refrigerant, then expansion valve supplies low temperature low pressure liquid refrigerant to tubular evaporator for evaporation to achieve chilling efficiencies. The temperature of refrigeration part is reduced to below 0℃ by ethylene glycol or brine. After that, it is supplied to used equipment.
Scope of use: In the industrial manufacture sectors which need averagely low-temperature water-cool.

Fully-closed turbine low-temperature air compressor
    Air compressor: using fully-closed turbine air compressors of globally famous brand-names such as DAIKIN、COPELAND、SANYO、MANEUROP , Performer. It has higher efficiency of 20%-30% than piston air compressors with such dominating features as stable performance, high efficiency, low incident rate, convenient maintenance. Based on customers’ request, one or more air compressors can be used, air compressor can change in accordance with sub-load, automatically interchange operation, balance working hours of air compressors, save power, extend cooling machine’s life span.
(Fully-closed turbine air compressor uses refrigerants such as R22、404c、R407c、R134a)

Winged condenser and tubular evaporator.
    Condenser:uses different heat exchanger copper tubes imported from Germany, Japan or domestically produced, the heat exchanger copper tubes of high efficiency are transparently threaded and the wind guide winged  is made of water permeable corrosion- resistant thin the mechanical tube so as to closely join the copper tube and aluminum pad, promote optimally the heat transfer efficiency. This condenser has such advantages as compact structure, small volume, light weight, high heat exchange efficiency, easy maintenance and cleaning.
    With ethylene glycol, the evaporator uses internal thread high effective heat exchange copper tube, thereby increasing the heat exchange area, improving heat transfer efficiency, and saving energy.
    With brine, the evaporator is made by 316L stainless steel or copper alloy, which is resistant to alkali and corrosion, thereby increasing efficiency and longevity of the machine and help maintain machine stable performance.
   
Cooling Units
    Cooling Units: Using the well-known global 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, load automatic increase and decrease, on-off timing and record of incident causes. The operation is simple and easy. Its automatic protection function can prevent the machine from damage during operation, extend the longvity of the machine and perform remote control and central control.

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 (reverse-phase, phase shortage), protection devices of anti-freezing, safety valve  or safety bolt, are best protecters of the machine
