Description
Hareyes horizontal two-stage compression permanent magnet variable frequency screw air compressor
-
Adopts a new type of horizontal dual-stage screw compressor host with an optimized internal structure. The efficient two-stage compression air compressor increases air delivery by 15% compared to a single-stage compression air compressor of the same power.
-
The compressor host and motor adopt direct drive transmission, improving transmission efficiency, reducing mechanical losses, and avoiding supply shortage due to transmission failure.
-
Uses an efficient cooling system, improving cooling efficiency with a large cooling air volume, extending the service life.
-
Adopts a permanent magnet synchronous motor with motor phase sequence protection to prevent motor reversal, ensuring the compressor runs efficiently.
-
Fully intelligent control, system operating conditions dynamically displayed, with real-time monitoring of important parameters.
