◆In industrial production and some fields, there is compression of flammable, explosive, and corrosive gases. By utilizing the low-temperature characteristics of water lubrication, compressing flammable and explosive gases is absolutely safe. With the corrosion resistance of stainless steel hosts, various corrosive gases can be compressed.

◆Granklin has successfully developed special gas compressors such as gasoline compressors, nitrogen compressors, oxygen compressors, carbon dioxide compressors, biogas compressors, acetone compressors, etc.

◆The compression ratio of the second stage compression is 60% lower than that of the first stage compression. The compression ratio is low, and the reflux leakage is greatly reduced, resulting in an increase in the output flow rate of the screw host. Low compression ratio reduces the heat generated during the compression process, which can improve the volumetric efficiency of compressed air.

◆Adopting two-stage compression technology improves the energy efficiency of the compressor, and the compression process is closer to isothermal compression. Under the same working conditions, two-stage compression saves about 20% more energy than one-stage compression.

◆When the compression ratio is low, the axial and radial forces generated by the rotor are greatly reduced, greatly improving the service life and reliability of the rotor bearings and rotor.

◆In industrial production such as textiles, glass, plastics, water treatment, chemicals, and cement, various low-pressure compressors with gas supply pressures of 0.15-0.4MPa are widely used.

◆Using a low-pressure compressor saves more than 30% energy compared to a low-pressure screw compressor produced with a conventional host, which can reduce significant energy losses.

◆In industrial production such as pharmaceuticals, electronics, chemicals, microbial fermentation, blow molding, pressure testing, and power plants, there are many applications that require medium pressure compressed air ranging from 1.6 to 4.0 MPa.

◆Currently, piston air compressors are mostly used domestically and even internationally. However, piston air compressors have high vibration, high pitch, large leakage, and short service life, resulting in low efficiency and low gas production for the same power.

◆The medium pressure oil-free screw machine has a compact structure, high overall working efficiency, low noise, small vibration, easy maintenance, low operating costs, and good air quality.

◆At the same time, this series of machines adopts a microcomputer control system, and the whole machine is equipped with multiple protection functions such as pressure, temperature, and overload.

◆ Constant pressure control: It can achieve high-precision constant pressure control with a pressure fluctuation range of 0.01MPa;

◆ Variable frequency soft start: eliminates peak current during startup, avoids grid impact, and improves flexibility by gradually adjusting speed to avoid current impact.

◆ Eliminate no-load: The compressor should eliminate no-load during operation to reduce energy consumption;

High performance vector control: large low-frequency starting torque, low operating current; Obtain reasonable torque to drive the air compressor smoothly while ensuring minimal temperature rise of the motor within a wide speed range;

◆ Intelligent start-stop

◆ Detect the ambient temperature to prevent high-temperature malfunctions caused by excessively high ambient temperature

◆ Monitor the pressure at the end of the post-processing equipment to effectively prevent excessive pressure difference in compressed air, which can lead to energy wastage

◆ Detect the motor temperature to protect the motor
