The basic principles of SD-120P-type snow ice machine: SD-120P-type snow ice machine uses liquid freon through the evaporator (cooling coil) evaporation, heat a large amount of ice absorb water into low-temperature low-pressure gaseous refrigerant , low-temperature and low-pressure Freon compressor absorbed through effective cooling condenser, converted back to liquid freon, flows through the expansion valve, returned to the evaporator, thus forming a refrigeration cycle, the expansion valve has the effect of throttling, if the cooling effect Freon by the speed of the expansion valve will soon, we say good effect ice machine, if the heat is not good, freon through the expansion valve will slow speed, this is the cooling effect of the ice machine is not good SD- 120P-type snow ice machine features: (1) rely on advanced refrigeration technology and accessories composition, creating a new generation of ice machine (2) circular arc-shaped four-door design, beautiful and elegant, made of stainless steel, durable, sanitary, easy to clean ( 3) detection microcomputer control system, fault less easy for customers to debug ice (4) snow ice machine with high efficiency, high stability of vertical evaporator, cooling, off the ice fast, time-saving (5) snow system ice machine uses a CFC-free foam compartments with independent cleaning function, with adjustable balanced feet Features: ● Automatic Ice, microcomputer automatic control system, convenient, safe and stable. ● quality and efficient use of CFC-free compressors, refrigeration effect, low noise, more stable and reliable. ● high quality stainless steel shell, durable anti-corrosion, one independent structure, space-saving, attractive appearance. ● cabinet insulation layer is CFC-free foam insulation effect, antibacterial liner to CFC-free, energy-saving and environmental protection. ● Using patented technology, the line chamber spacer ice making evaporator, high cooling efficiency, large capacity ice. ● full of ice, lack of water, cold protection display, fault warning display and other protective shutdown. When the ice is full of water ice machine will automatically shut down when the water supply is automatically boot, with automatic memory recovery. ● screw extrusion hob-style ice type, the ice is amorphous, fine granular snow ice, small ice shape, can penetrate the narrow gap, cooling speed, good ice bath effect, specially designed for laboratories . ● Unique float-type water tank system to ensure that no residual water, no de-icing process, water loss, no residual water, saving water and energy. Ice shape, good ice bath effect, specially designed for laboratories. Whole small, space-saving stainless steel shell, beautiful and practical. Quality ice refrigeration systems, ice fast, energy efficient. Board microcomputer control system, process monitoring, perfect protection. The front has a power switch, easy to use. All computer-controlled, automatic ice, the ice type of snow ice. Stainless steel housing, efficient CFC-free compressor, ice cycle: by replenishing water valves, water automatically enters a water storage tank, and then by the flow control valve will be sent to the diversion of water through the pump head, where the water evenly sprayed onto the ice On the surface, the same as the water curtain flowing through the wall surface of the ice, the water is cooled to the freezing point, without being evaporated frozen water will flow into the water storage tank through the porous grooves, restart cycle work. Mining ice cycle: when the ice reaches the desired thickness (by the operator / user to arbitrarily select), the hot gas discharged from the compressor re-directed back to the ice maker in the folder wall, a substituted low temperature liquid refrigerant. When this wall between the ice and the evaporation of water to form a thin film layer, this layer of water film will be free to fall into the slot below the ice by gravity role, played the role of lubrication. The water in the ice harvest cycle generated will return to water reservoir through a porous groove, so that also prevents the machine wet ice is discharged.
