The characteristics of vertical refrigeration compressor
1, high efficiency
Using unique motor design, the movement of parts optimization design gap and achieve the best motor and pump Matching and high efficiency.
2, low noise Using composite silencers enclosures, advanced exhaust structure and sophisticated manufacturing, product assurance running very low noise.
3, high reliability
The selection of high-quality raw materials, good lubrication system design, advanced processing technology and stringent quality control, is the fundamental guarantee products reliable operation.
4, low vibration
High pump body rigidity and precision balancing design, a small compressor to ensure that the vibration

Vertical refrigeration compressor for attention
1, prior to injection compressor factory adequate refrigeration oils, should not be used arbitrarily add and should not arbitrarily join other brands of frozen oil Otherwise, it will damage the compressor.
2, the compressor to a higher residual moisture content requirements, there is access to the compressor refrigeration system can be removed in front of the mouth of a rubber plug, and should be within 10 minutes complete welding (assembly), so as to avoid entering the compressor and water the entire cooling system caused harm.
3, in the operation of refrigeration compressor motor by the media R22/R407C/R410A cooling, then the lack of refrigerant medium case not run the compressor.
4, the internal compressor in a vacuum, no running compressors, or internal arc currents will damage the internal parts.
5, compressor operation should be started again after the shutdown intervals three minutes more.
6, the compressor should remain vertical and horizontal surface, the largest installation tilt angle not greater than 5 °.
7, refrigerant from the condenser refrigeration system into the tail, and it can not directly injected into the compressor.
8, prior to the commencement of the compressor should be carefully examined current and wiring is correct, and may not lead to contact with the surface of compressor
