产品介绍
The DJ-1/350 to DJ-10/350 series is our 400 bar class of water-cooled, large-displacement high-pressure compressors. Five models deliver 1–10 m³/min at 35–40 MPa through 4- to 5-stage compression, driven by 30–185 kW motors. The water-cooled circuit stabilises interstage and after-stage temperatures for continuous duty in cylinder filling, test-rig and process service.
The DJ-3/350 delivers 3 m³/min at 35 MPa, combining dependable multi-stage compression with automatic protection and low operating cost. Dejue (BS986) manufactures this unit in-house to CE and ISO standards, with full documentation, spare-parts support and export packing as standard.
