SDS HITACHI OIL-FREE SCREW COMPRESSOR

Characteristic features
APC：Active Power Control
When APC is activated, the controller calculates the piping pressure loss according to the change of air consumption from the load ratio and decreases the discharge pressure.

PSC：Power Save Control
When PSC function is activated, unload pressure is automatically decreased until cycle time reaches the minimum time (30 sec.).
Then average pressure is decreased, and power is decreased

ASS: Auto Start and Stop
5% Energy Saving
Reducing CO2 emission by approximately 48tons annually


About Coating
• PFA（HITACHI）：Polyfluoroalkoxy
• PTFE（Other markers）：Polytetrafluoroethene
Maximum service temperature of 260°C/500°、non-stick

Newly developed resin coated rotor
A newly developed coating is applied to the surface of the UH profile rotor to increase its durability. The new resin coating give a uniform pin-hole-less coating over the rotor and shuts off the penetration of water for a long period.
