The industrial benchmark for continuous power frequency installations, built to run 24/7 in harsh operating conditions with extreme reliability.
In modern macro-industrial processing, compressed air remains a vital utility alongside electricity and water. While variable speed drive (VSD) systems are often highlighted for variable loads, fixed speed screw air compressors represent the backbone of heavy manufacturing, metallurgy, glassmaking, chemical processing, and continuous air separation units.
When an industrial plant operates at full, steady-state capacity for extended shifts, the thermodynamic efficiency of a fixed speed screw air compressor running at its design sweet spot outperforms VSD equivalents by bypassing the 3-5% electrical switching loss inherent in frequency inverters. Our industrial twin-screw rotors are engineered precisely to achieve maximum volumetric efficiency at designated motor frequencies, guaranteeing uninterrupted supply and exceptional resistance to grid voltage spikes.
Our engineering architecture centers around the asymmetrical twin-screw rotor profile, featuring a 5:6 ratio that reduces blow-hole leakage by up to 20% compared to traditional 4:6 profiles. This geometry maximizes suction volume while keeping discharge temperatures low. Combined with IP55-rated F-class insulation motors and direct-coupled elastic drive mechanisms, these units achieve extreme efficiency. They avoid the mechanical slip losses of belt-driven systems, ensuring stable power delivery.
