3. The unit runs smoothly and the life is increased, avoiding high temperature shutdown;
4. Adopt enlarged frequency conversion fan, centrifugal fan above 75kw, uniform heat dissipation, low noise and large air volume;
05 Customized enlarged oil and gas system
1. Enlarged oil and gas system, small pipeline pressure loss;
2. Good heat dissipation effect, stable equipment operation;
3. Good oil and gas separation effect, the oil content of the outlet gas is less than 3PPM;
06 Customized double air intake filtration and external air intake guarantee
1. External air intake filter: filter dust cotton, washable, to prevent impurities from entering the machine body;
2. The air filter of the air compressor adopts horizontal air filter intake, and the filtration accuracy reaches 1μm;
3. The two-layer filtration can well protect the use of the air compressor host and lubricating oil, and reduce the failure rate of the electrical parts;
4. The air filter inlet is equipped with a guide device to ensure the low external air intake temperature and improve the efficiency of the whole machine by 2%;
07 Intelligent control system + remote Internet of Things
1. On-site, mobile phone, and computer simultaneously display: operating status, operating data, fault warning, etc.;
2. Real-time online monitoring: pressure, power, temperature fluctuations;
3. Users, service providers, and manufacturers display simultaneously to improve communication efficiency and better escort the stable production of enterprises;
08 Ambient temperature design and test standards: 12℃ higher than the international standard
1. The industry international design standard is 40℃, and SEIZE strictly follows 52℃ Standard design;
2. It can be shipped only after passing the 52℃ high temperature test standard;
09 Overall piping system-stainless steel precision drawing tube
1. Simple structure, avoiding aging and oil leakage;
2. The precision drawing tube has high internal and external finish and small pipeline pressure loss;
3. It will never rust and has an overall beautiful appearance;
10 ​​Built-in and reserved heat recovery
1. Zero heating cost: Use the heat discharged from the air compressor to the environment to generate hot water, and the recovery efficiency can reach about 60% of the unit input power;
2. It is beneficial to the heat dissipation of the air compressor: reduce the power consumption required for heat dissipation, which is beneficial to the smooth operation of the air compressor;
3. It is beneficial to environmental protection: reduce the heat discharged by the air compressor into the environment;
4. Repeated consumption reduction of enterprises: The recovered hot water can be used for employee bathing, preheating of boiler water, circulating air conditioning water, etc.
