The TVD+ series 5.5 kW permanent magnet two-stage variable-frequency screw compressor combines a two-stage compression unit with an IE5-class permanent magnet variable-frequency motor, delivering overall efficiency 15–20% higher than China's National Grade 1 energy standards—a cost-effective energy-saving solution specifically designed for small workshops.
The TVD+ series 15 kW permanent-magnet two-stage variable-frequency screw compressor features a dual-screw unit paired with an IE5 motor, delivering overall efficiency 20% higher than that of single-stage models and providing stable, clean, energy-efficient compressed air for small to medium-sized production lines.
The TVD+ series 22 kW permanent magnet two-stage variable-frequency screw compressor employs dual energy-saving technologies—two-stage compression and permanent magnet frequency conversion—with an overall efficiency 15–20% higher than that of Class 1 units, making it the ideal solution for energy-efficient upgrades and air source enhancement in medium-sized manufacturing facilities.
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 45 kW models in the TVD+ series feature a twin-screw drive unit paired with an IE5 permanent magnet motor, delivering ultra-high energy efficiency at this power level. Specifically designed for ensuring stable gas supply in large-scale industrial production lines, as well as in the chemical and energy sectors.
The HUADA TVD-75+ is a 55 kW two-stage permanent magnet VSD screw air compressor for higher-demand industrial air systems. Its listed air delivery at 0.7 MPa is 12.1 m³/min for the 0.6-0.8 MPa version or 9.6 m³/min for the 0.6-1.0 MPa version. The air-cooled package combines an integrated horizontal drive with an internal oil separator.
