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 exchanger: shell and tube type condenser, shell and tube evaporator, bilateral enhanced heat exchange tube, greatly improve the heat transfer efficiency; heat exchanger compact structure, the end plate removable, easy to clean and maintain.
3. 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.
4. 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
5. 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
