Danfoss Wood concept
NWC
Nessie® Wood Concept,
type NWC
The Danfoss Wood Concept is a compact and
exible high pressure humidication unit
designed for lumber drying, dust suppression
and saw blade lubrication
Optimum protability 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 benets 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 thoughtthrough 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 lter lters o 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 humidication unit is
supplied with up to 8 outputs due to customer
specications, 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 t for installation in
new applications as well as retrot in existing
kilns.
• The high pressure water humidication 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.
