The two-stage compression energy-saving oil-injected screw compressor has a unique host design. It not only has all the advantages of a single-stage oil-injected screw air compressor, but also has a more reliable and energy-saving operation due to the low compression ratio of each stage, small force on the rotor and bearings, large rotor diameter and low speed.
The TVD+ series 37 kW two-stage variable-frequency screw chiller is specifically designed for medium-to-large production lines, delivering overall efficiency 15–20% higher than China's National Grade 1 energy efficiency standard. It maintains stable output and ultra-low energy consumption under heavy loads, making it an ideal solution for continuous production operations.
The LGGPM-350 features a robust 250 kW power output, delivering stable compressed air at 55 m³/min under 0.7 MPa pressure. Its independent air duct system scientifically separates the air intake for filtration, cooling, and overall operation, complemented by a biomimetic centrifugal fan to provide a cool and stable operating environment for high-power units.
The LGGPM-425 is a 315 kW ultra-high-power air-cooled unit that delivers 65 m³/min of compressed air at 0.7 MPa pressure. Featuring a modular design and high-strength sheet metal housing, it is specifically engineered for heavy industrial applications requiring continuous high-flow air supply, such as steel manufacturing, mining, and shipbuilding.
The HB-30TD is the high-power flagship model in Huada's medium-pressure integrated machine series, delivering a main unit output of 22 kW with a large air volume of 2.2 m³/min and stable pressure of 1.6 MPa. It is specifically designed for high-power fiber laser cutting machines exceeding 3000 W and heavy-duty cutting production lines. Its integrated "key engineering" solution eliminates the costs associated with coordinating multiple equipment purchases, ensuring immediate readiness for use and reliable performance.
