manufacturer of all additional equipment for wood dryers beside electronic
equipment for measurement and control of the ambient conditions in the kiln.
That way, our customers get everything they need to start drying the wood
imidiatelly. This equipment is mainly manufactured and assambled by "NIGOS", or
in some cases parts are purchased from the world leading manufacturers and then
assembled by "NIGOS". "NIGOS" gives its customers 1 year warrenty for entire
kiln and kiln's equipment and 5 years warrenty for automatic control units used
Kiln chamber can be constructed
of concrete or bricks by user, or assembled of aluminium bearing structure
provided by "NIGOS". The walls and the roof, as well as the kiln doors are made
of insulated aluminium coated panels with foamed polyuretane. Rubber gaskets are
put on the both side of the doorframe to ensure the total sealing. The main door
can be winging or sliding with special mechanism for opening and closing. Every
kiln is provided with an inspection door.
Air circulation is provided by
flow fans placed under the ceiling. Flow fans are mounted on the aluminium "L"
bearing structure, while the empty spaces between them are closed with aluminium
plates. Axial fans with aluminium structure are used. Propelers are made of
polyamid and strenghtened with glass-fibre. Engine is tropicalized (resistent to
increased humidity and temperature). Fans can be mono-directional or
bi-directional (reversible), depending on the type of dryer.
Air exchange system in the
dryers with mono-directional air circulation consist of flaps with fans and
automated shades. In dryers with bi-directional air exchange servo-controled
dampers (flaps) are used. In both cases dampers are made of aluminium plates and
can provide a homogeneous air exchange.
Heat recovery units can be
mounted on conventional wood dryers (kilns). Great impact on environment
preservation is possible with minimum investments. These HR units can save more
than 30% of heating energy (and consequenly fuel for boiler), reduce drying time
and improve quality of drying. Heat recovery units are installed on the back of
the kiln instead of standard air exchange system with dampers.
Production of cold steam (spraying) using high presure
provide quality moisturizing of a timber during drying process.
Humidifying system consist of water pump, filter, valve and sprinklers.
Bimetalic heat exchangers are
made of quality stainless steel (INOX) finned tubes. Finning is made of
aluminium fins. This ensures good heat transfer and long exploatation in harsh
conditions inside drying chamber. Working medium can be hot water or steam.
Stainless steel electrodes
(wood MC probes) fitted in wood constantly measure wood moisture content (MC),
while precise probes that do not need special maintenance during drying process
measure temperature and equilibrium moisture content
(EMC). Automatic control units use this measured values to control drying
