Because no oil is allowed in the compression chambers, the two-stage rotary screw compressor is able to provide completely oil-free compressed air.
Fixed speed, also known as load-unload, provides energy-efficient operation during loaded and unloaded operation. Oil-free air is required for pneumatic cylinders, blowing and spray guns.
Other finishes are available for extreme environments. Air-cooled heat exchangers are made of heavy-duty aluminum with a special coating and are designed for all published operating conditions.
The labyrinth type seal used on the drive end ensures leak-free operation. Rogers Machinery Company, Inc. Kobelco KNW Series water-cooled models feature highly efficient, removable, copper tube bundles. The compressor components are arranged in a single modular design, forming a surprisingly compact unit that is then mounted on vibration isolators to a structural steel base no special foundation required.
VFD control provides a narrow system pressure band, reduces inrush at start-up, and allows more frequent stops and starts. The valve is designed for 1, load-unload cycles and is easily serviced. Also included is an SD memory card. Messages are sent to direct the operator for service, pre-alarms, and alarms, and will be shown when necessary. Fixed Speed or VFD.
