All values are also available for remote monitoring. Other finishes are available for extreme environments. The compressor will not operate until oil pressure is established. Oil Filter with Differential Indicator. This course is designed for KNW compressor service personnel who are responsible for maintenance and equipment repair.


VFD control provides a narrow system pressure band, reduces inrush at start-up, and allows more frequent stops and starts. Kobelco KNW Series water-cooled models feature highly efficient, removable, copper tube bundles. Competitors use an overhung design. Messages are sent onw direct the operator for service, pre-alarms, and alarms, and will be shown when necessary.

Kobelco KNW Series air-cooled models include a thermostatic mixing valve to insure proper oil temperature in changing ambient temperatures. An audible alarm is provided for alarm annunciation. All water and air-cooled models have oversized moisture separators with automatic drains for maximum efficiency.

The valve is a positive-closing disc type with orifices, using spring and air pressure to activate. They can be designed according to customer preference.

This design includes a patented, high-efficiency super rotor profile and cooling jackets. Fixed Speed or VFD. Air-cooled heat exchangers are made of heavy-duty aluminum with a special coating and are designed oobelco all published operating conditions.

Air is inside of the tubes and water is in the kknw. Competitors use carbon rings with single vents and no thrust balance.
