Safety SYG Series Oil Seperator
SYG series oil separator primary used for Piston compressors,Piston parallel compressor units and the secondary oil separation of the spiral machines. SYG series oil separator features a centrifugal separation that can achieve high efficiency of oil separation with minimal pressure drop. The helical guide platecan keep high oil separation efficiency while the parallel compressor unit in load shedding or load change. There was installed a mist eliminator with stainless steel wires inside the oil separator, thus forming a barrier that captures the misty oil, making the oil flocculate,causing them toimpact each other, gather, and adsorb onto the mist eliminator to become oil droplets, finally reach the oil collection area of the separator by gravity. In this area, there was a flange that can separate the impurities of the oil droplets, also there was a permanent magnet which means it can absorb the iron debris. Designed pressure：3.0MPa；
Safety SYA Series Oil Seperator
SYA series oil separator primary used for Piston compressors and Piston parallel compressor units.The gaseous refrigerants with suspended oil particles from the compressor enter into the oil separator, and go through intercept of the metal wire mesh from the inlet and outlet of the oil separator, the oil particles impacting each other and to form the heavier oil particles; Finally, the heavier oil particles impacting the inner wall of the oil separator to separate. The separated oil drips to the bottom of the oil separator and returns to the crankcase or oil reservoir through the float ball needle valve.
Safety SQM Series Gas-Liquid Separators
The sunction accumulator is an important part of the refrigeration system. The most important function of the separator is to separate the gaseous and liquid refrigerants for preventing “liquid slugging” of compressor (liquid refrigerants flows into the compressor). Reasons to cause “ Liquid Slugging”： Improperly installed piping（inlet-outlet） Insufficient capacity of evaporator Expansion valve selection error Refrigerants overcharging Over Frosting of evaporator Evaporator fan not running Insufficient heat insulating and low environment temperatures of suction pipes Recommendations to install: Compressor parallel Two-stages compression refrigeration/compound refrigerants compressor Flooded evaporation system Defrosting system by superheated vapour Heat-pump system Over-heat degree lower than 7K system Attentions to choose： Determine the relationship between the volume of the sunction accumulator and the amount of the system refrigerants charging. Basically, the sunction accumulator can store 30 percent to 50 percent refrigerants of the system. The flow velocity of U-shaped vertical raising pipe not lower than 7.5 m/s in order to favorable oil return effect,and not greater than 12 m/s, especially low evaporating temperature system. Capacity controlled refrigerating units should be considered the velocity of the suction pipe;for the parallel compressor unit, the multiple suction pipes of the separator should be the best choice. (Multiple suction pipes separator is installed behind the suction pipe, one suction pipe for one compressor to make sure every compressor can get the same velocity). Vertical installation Install close to the suction inlet of the compressor Designed pressure: 3.0MPa Applicable refrigerants models: R134a, R22, R407c, R404A, R507A
When the SGS series filters are used as liquid supply line filter, installing solid dry filter cartridges can filter impurities, absorb moisture and acidic substances in the system; When used as suction line filter, we recommend to remove the two metal filter in order to reduce pressure drop. Using SFE series fiber pleated and SFE-W stainless steel cartridge shall effectively filter out the impurities in the system and avoid the dirts entering the compressor to extend the service life of the compressor.

BITZER has always focused on improving compressor efficiency and launched the ECOLINE series of compressors specifically optimized for R134a several years ago. The R134a refrigerant has high performance in medium and high-temperature heat pump applications, including very high efficiency, lower pressure (reducing leakage rate), and the lowest GWP among all non-flammable HFC refrigerants.
During operation, the high-pressure outlet of the refrigerant compressor usually contains a large amount of refrigerant oil. To protect the compressor from oil loss and prevent refrigerant oil from flowing into the system and affecting the heat dissipation function of the condenser and the refrigeration effect of the evaporator, an oil separator must be installed to separate the refrigerant oil and refrigerant. Then, the float structure inside the oil separator uses the high and low pressure difference principle to force the refrigerant oil to flow back to the compressor crankcase through the return oil pipe. This ensures that the compressor does not lack oil and achieves the best refrigeration effect.
