250KW Low-Pressure Screw Air Compressor (Air-Cooled)
Designed for industrial-scale low-pressure air supply, this 250KW air-cooled compressor delivers a robust 42.5m³/min air displacement at 0.8Mpa, ideal for mega-scale operations such as refineries, large-scale mining ventilation, and hyper-scale data center cooling systems. The twin-screw main unit features oversized 7:9 asymmetric rotors constructed from carbon-fiber-reinforced polymer (CFRP), achieving 99.2% volumetric efficiency at low pressure while reducing rotational inertia by 30% compared to steel rotors.
The powertrain integrates an IE8 permanent magnet synchronous motor with a (magnetic levitation bearing) direct-drive system (99.5% transmission efficiency), achieving a groundbreaking 4.6kW/(m³/min) efficiency ratio (ISO 1217:2025) across 15%-100% load ranges. Equipped with a neural network-controlled VFD, it maintains ±0.008MPa pressure stability while cutting energy consumption by 50% versus traditional gear-driven models. The five-stage oil separation system employs nanofiber electrostatic filters and plasma ionisation, ensuring oil content ≤3ppm-compliant with ISO 8573-1:2010 Class 2.2.1 for heavy-industrial and critical infrastructure applications.
Air-cooling innovation features a micro-channel aluminum radiator with embedded phase-change material (PCM) cooling panels, coupled with AI-optimized axial fans that adjust pitch in real time based on thermal imaging, enabling continuous operation in 60℃ ambient temperatures without performance loss. Noise reduction utilizes a hybrid active-passive acoustic barrier system, combining adaptive sound wave cancellation with layered viscoelastic foam, limiting operational noise to 78±2dB(A)-remarkable for a compressor of this scale.
The intelligent control platform includes a 24-inch industrial-grade touchscreen with edge computing capabilities, monitoring 60+ parameters such as rotor dynamic balance, oil conductivity, and fan blade wear in real time. Integrated 5G-Advanced/Industrial IoT connectivity supports digital twin-driven predictive maintenance, with AI algorithms predicting component lifespan within 95% accuracy. Maintenance is revolutionized by quick-exchange filter cassettes and a self-purging oil circuit, reducing routine service time to 10 minutes and extending filter replacement intervals to 3,000 hours. The compressor's ruggedized steel frame (2,500kg net weight) and forkliftable skid base facilitate easy installation in challenging industrial environments, while its modular design allows parallel scaling for centralized air supply networks.
Standard configurations include G8"" air inlet and DN150 flanged outlet, compatible with heavy-duty ductile iron pipelines, making it ideal for 24/7 operations in petrochemical plants, marine cargo handling, and large-scale agricultural aeration systems. Its combination of massive airflow capacity, magnetic levitation-driven efficiency, and industrial-grade durability sets a new benchmark for low-pressure compressed air solutions in high-stakes, high-demand industries.
