SE Series Two-Stage Permanent Magnet Screw Air Compressor
| Product | SE Series Two-Stage Permanent Magnet Screw Air Compressor | ||
| Category | Air Compressors | ||
| Description | The SE series two-stage permanent magnet screw air compressor inherits the advantages of twin-screw compressors — simple structure, flexible installation and high efficiency — while highlighting high-efficiency energy saving: staged compression reduces the single-stage compression ratio, lowering bearing load and improving volumetric efficiency, with higher efficiency and greater savings under partial loads. Compared with single-stage twin-screw compressors, two-stage compression saves up to 15% energy. At 8000 running hours per year, this means substantial annual electricity savings. Inter-stage injection cooling lowers the temperature of gas entering the next stage, further reducing compression work. Models from SE-50V to SE-350V deliver 7.2–55 m³/min displacement with 37–250 kW power and noise of 72±2 to 82±2 dB(A) — for industrial customers with large air demand and high efficiency requirements. | ||

FAQ
Q1: How much energy does two-stage save vs. single-stage?
Up to 15%, meaning significant annual savings at 8000 running hours.
Q2: Why is two-stage more efficient?
Staged compression lowers the single-stage ratio and reduces wasted work; inter-stage cooling further cuts compression power.
Q3: What models are available?
SE-50V to SE-350V, 7.2–55 m³/min, 37–250 kW.
Q4: What conditions suit it?
High air demand, frequent partial-load operation and high efficiency requirements.
