250KW VSD 0.8~1.3MPa oil inject screw compressor
Détails du produit
The AIRERA 250kW VSD Oil-Injected Screw Compressor is custom-engineered for extreme heavy-duty demands and high-pressure applications. Supporting a wide pressure adjustment range of 0.8–1.3MPa, this unit precisely matches diverse industrial requirements, from standard manufacturing to high-pressure blowing processes.
At its core, the AIRERA intelligent VSD system works in harmony with a low-speed, large-rotor air end. This ensures superior energy efficiency even under continuous high-pressure output, achieving comprehensive energy savings of over 35%. To manage the thermal demands of its massive 250kW capacity, the unit features optimized oil-gas circulation and cooling systems, significantly extending mechanical life while maintaining premium air quality. Combined with AIRERA IoT remote monitoring, it ensures 24/7 constant pressure and smart maintenance. The AIRERA 250kW series empowers large-scale industrial systems to achieve a green, low-carbon transformation through robust high-pressure power and ultimate frequency-drive efficiency.

High pressure implies higher heat and stricter sealing requirements. The AIRERA 250kW series features an upgraded reinforced oil-gas separation system and high-pressure specialized seals to ensure zero leakage. Additionally, we have equipped the unit with extra-large capacity coolers and intelligent temperature-controlled fans to keep the lubricating oil at an ideal working temperature, preventing oil emulsification or carbonization.
Safety is the primary directive at AIRERA. This unit includes multiple built-in protection mechanisms: automatic overpressure shutdown, motor overload protection, high discharge temperature protection, and emergency power-off protection. All pressure-bearing components undergo rigorous hydraulic and airtightness testing to ensure rock-solid stability even when running at full 1.3MPa loads.
For large-scale overseas projects, this AIRERA series offers customizable enhanced cooling configurations and moisture/dust-proof motor treatments. In regions with unstable power grids, our inverters feature a wider voltage fluctuation tolerance (±10%), ensuring the machine provides uninterrupted power for large industrial stations even in the harshest external environments.
