NWC |
Nessie® Wood Concept, |
|
type NWC |
||
|
|
The Danfoss Wood Concept is a compact and |
|
|
|
|
|
flexible high pressure humidification unit |
|
|
designed for lumber drying, dust suppression |
|
|
and saw blade lubrication |
|
|
Optimum profitability in the lumber business |
|
|
depends on human knowledge and experience |
|
|
of handling a living material. However, |
|
|
automation has become an indispensable tool for |
|
|
optimising the drying and sawing process. |
|
|
With the NWC, a range of new benefits are |
|
|
available for lumber drying and wood processing. |
|
|
The NWC operates at pressures between 80-100 |
|
|
barg [1160-1450 psig], producing extremely small |
|
|
water droplets evaporating immediately. |
|
|
|
|
|
|
Design and function |
The Danfoss Wood Concept is a turnkey system |
|
– complete and compact by design. It consists |
|
of a tank, a pump, an electric motor, valves and |
|
a control system. Among a range of thought- |
|
through design details can be mentioned: |
|
• The pump is solely water lubricated. |
|
Consequently, the pump requires no service |
|
or maintenance throughout its entire life. |
|
• An inlet filter filters off impurities. In that way |
|
both nozzles and pumps are safeguarded, |
|
cutting down service costs. Moreover, no |
|
possible contamination of the water will |
|
damage the lumber. |
•The high pressure water humidification unit is supplied with up to 8 outputs due to customer specifications, for control of one or several kilns, and even several sawing machines can be connected. More outputs can be added in case of increasing demand.
•The unit is equally well fit for installation in new applications as well as retrofit in existing kilns.
•The high pressure water humidification unit comes with an electric motor as standard. However, the unit can be supplied with a frequency converter motor, type FCP 106 from Danfoss for optimized process control.
