Product feature:
1. Refrigeration compressor: Germany / Taiwan Hanbell Bitzer semi hermetic screw refrigeration compressor, high efficiency, low noise, low wear and long service life etc.
2. Heat exchange: Air-cooled condenser for the hydrophilic foil copper tube fin so the heat exchange area and fin spacing appropriate adjustment according to the geographical environment high efficiency.Shell and tube evaporator inlet is specially designed to prevent the refrigerant inside each heat exchange tube of flow distribution more uniform, compact exchanger structure ,end plate removable, convenient for clean maintenance.
3.inner rotor fan: All aluminum shell motor, low speed , big horsepower . fan blade with elevation angle blade structure ,big air volume, static pressure is high, low noise , long service life. 
4. Refrigeration valve: the United States, Japan, Italy Emerson Saginomiya Castel, Danfoss and other brand-name accessories, some units with double valve control design of thermal expansion,ensure the load and the energy efficiency ratio of the system for operating more wide, cold quantity control precision is higher, the unit is always working in a reliable and efficient state.
5. Electrical parts: unit for electrical components are used for international brands, in English / double display man-machine interface touch screen balanced controller, intuitive operation of the unit operation is more simple, multi compressor system, automatic control system according to the operating conditions of the compressor running time, stable performance
6. Energy regulation: the unit has multi-level energy regulation, to meet the needs of cold load changes, the maximum energy saving effect, saving maintenance costs and operating costs.

Safety protection:
1. exhaust valve: ensure the compressor runs- after stop, to prevent high pressure exhaust gas reflux..
2. Phase protection: to prevent excessive voltage, less voltage, lack of phase protection, reverse phase protection, to prevent the compressor reverse and damage..
3. oil heating protection: before refrigerator runs, forced to set the oil heating procedures to ensure that the oil dilution and liquidity, satisfy the lubrication conditions before operation.
4. compressor internal motor winding thermal protection: to prevent the compressor excessive load or bad condition put the coil temperature too high and burned the compressor.
5. high and low pressure protection: when conditions are bad and failure, high and low pressure switch action protection, protection compressor and system safety..
6. safety valve: ensure the condenser  working in the safe range.
7. water protection: to prevent the unit running without water.
8. anti icing protection: when the unit running, prevent the water temperature too low, the formation of internal evaporator icing and damage the evaporator.
9. overload protection: double protection of soft and hard to ensure compressor overload safety.
10. compressor oil pressure protection: the unit is running, due to poor oil system, leading to insufficient oil pressure, timely protection of compressor.
11. Oil level protection: compressor protects the compressor when the system less oil.
The unit is widely used in: aluminum oxide, aluminum oxide, electroplating, hard plastic, injection molding, extrusion, foaming machine, hydraulic equipment, laminating machine, bottle blowing machine leather embossing machine, composite flooring, food, chemical, biological, pharmaceutical, electronics and other industries


The dust skeleton is the rib of the filter bag. It should be light and easy to install and maintain. The quality of the frame directly affects the filtering state and service life of the filter bag. The natural granite is used to process the circular curved plate through mechanical processing. The whole structure is smooth and smooth. It has the characteristics of corrosion resistance, abrasion resistance and high temperature resistance. The exterior is poured with high strength and high temperature resistant and alkali resistant materials. The strength and life span of the equipment are greatly enhanced by the outer protective steel plate of the barrel equipment. The body uses 1 meters per section structure, the joints have concave and convex joints at each joint, and the joints are connected with furan resin or acid alkali glue mud at the joint to ensure that the connection is not leaky; overcoming the common faults of the seeping and air leakage of the original granite duster. The upper sink. For the ceramic structure, the ceramic Dust Collector ensures no water leakage in the water supply process, avoids the seepage setback of the original granite duster water trough, and strengthens the use effect of the dust collector. The simple installation is 1 meters per day, and the site can be installed for half a day, reducing the construction period.
