  • a) KILN EQUIPMENT
  • Supporting structure: The perimeter carrying structure is completely made of special alloy
  • aluminum extruded profiles, which have high resistance to corrosion.
  • Some other components are in stainless-steel. All columns, front
  • beams, roof holding structure, fan holding beams, bottom beams,
  • windbracing are of corrosion resistant aluminum meeting the
  • international standards and allowing an easy-assembly of the
  • elements. The fans are built into aluminum beams which are
  • constructed with our special aluminum profiles, including
  • intermediate aluminum enclosures to avoid short-circuiting of the air.
  • The aluminum profiles are made to our own exclusive patented
  • design. Used aluminium alloy: Al Mg 0,5 Si 0,4 Fe nach UNI 6060
  • T6.
  • Insulation system, Secea s
  • patent EUREKA:
  • The thermal insulation is made by means of the following material:
  • aluminum and high density glass-wool, with 100 mm thickness, in
  • order to achieve the max. insulation and energy saving. The mineral
  • fiber is stuck to the aluminum walls and perfectly supported by a
  • special aluminum frame, which makes the panels self bearing and
  • modular, allowing an easy and quick assembly. The panels are
  • fastened by means of rugged aluminum claws. The construction of
  • such panels, totally new, allows to achieve a very good thermal cut,
  • which decreases the heat losses to much smaller values than the usual
  • panels. The panels are sealed by special silicon gaskets, housed along
  • the panel frame, resistant to high temperatures and to the corrosive
  • tannin acid. K-value: 32. The above modular self bearing panels and
  • the walls resulting from their coupling are an exclusive insulation
  • system, that only Secea can offer and is covered by patent all over
  • the world. Used aluminium alloy: UNI EN 9005/1, DIN 3.0505, Al
  • Mn 0,5 Mg 0,5.

  • Ventilation: Reversible air circulation produced by high efficiency aluminum
  • axial fans equipped with wing-shaped blades, reversible type.
  • The fans can perform the same efficiency and capacity in both
  • rotating directions (left and right) and at any revolution rate. The fan
  • blades shape is perfectly symmetrical. They guarantee the best
  • quality dried timber with the lowest energy consumption. The blades
  • are made by die casting in a special aluminum and silica alloy, that
  • guarantees the highest resistance at the most critical environment
  • conditions. The electrical motor is tropically insulated to resist high
  • temperatures, IP 55 protection level, class H to work free of
  • problems in environments reaching 100 % relative moisture, and is
  • equipped with proper bearings and cables to resist high temperatures.
  • We use Leroy Somer fans.
  • Variable speed drive: Multi-Inverter-System for fans speed control by means of variable
  • frequency inverter for each single motor. Inverters, with capacity
  • suitable to motors, will be installed for each fan inside the control
  • board. Any inverter is provided of EC mark with steel case, AC
  • three-phase reactances and other reliable design solutions enabling
  • you to protect from inlet electromagnetic noises and low outlet
  • emission. The most innovative possibilities of vectorial control at
  • open loop (there is no feedback) , speed ASIC circuit and current
  • measure in the three outlet phases are the basis of an excellent
  • dynamic motors control. We use ALLEN BRADLEY, Rockwell
  • Automation.

  • Vents: Made in aluminum. The regulation throttle valve is made of
  • aluminum and, thanks to a suitable silicon seal, assures a very low
  • heat loss, when it is in the OFF position. Suitable self lubricating
  • bushings ensure years of regular and maintenance free operation. The
  • throttle valves are proportionally operated by servomotors that drive
  • the opening and closing in order to regulate the climatic condition
  • into the kiln and getting a max energy saving . Vents are placed on
  • the front and rear walls.
  • Low pressure Humidifying
  • system matched with HIGH
  • PERFORMANCE
  • HUMIDIFICATION
  • SYSTEM BY JET FOG
  • Special Humidification System averaging 25-30 microns water
  • particles, assuring the most homogeneous timber humidification, thus
  • reducing the initial conditioning phase. This system is suitable for
  • operation with low pressure cold water.
  • The fogging fan, (3/4HP) provides the best quality of fog and can
  • propel its fog up to 9 meters. It has a maximum fog output of 90
  • LT/H, but is fully adjustable even down to the lowest fogging levels.
  • This system will be built in together with standard low pressure
  • sprayers, using nozzles for up to 5 bar pressure water.
  • In kiln model JET 76.70.41 two units will be installed.
  • In kiln model JET 46.70.41 one unit will be installed.
  • Intermediate ceiling: Intermediate ceiling made of corrugated aluminum plates, fixed to
  • the ceiling by means of long aluminum profiles and stainless-steel
  • screws.
  • Sloped roof: Insulated by the above described patented panels. The covering is
  • made of corrugated aluminum sheets. Suitable spacers are applied in
  • order to create a slight slope permitting rain water to flow to the
  • gutters water spouts, placed on the rear side of the kiln.
  • Upper air baffles: Suitable rubber flaps, resistant to high temperatures, are installed in
  • the middle of intermediate ceiling beam in order to close the gap
  • between the timber and the intermediate ceiling thus allowing the
  • most efficient air flow. The flaps are not equipped with manual
  • adjust system.
  • Sliding Door: As for all the other profiles of the cell, the doors are also made with
  • special aluminum structure.
  • The ribbing systems and the joints allow the lodging of the neoprenedutral

  • automatic control unit:
  • Automatic control system with industry PC and 5 touch screen.
  • The touch screen allows a direct control thanks to a graphic software
  • which is user friendly and highly intuitive, able to offer the
  • following advantages:
  • - real time prompt visualisation of the data, of the real and set
  • values and of their curves.
  • - real time selection among all parameters and programs
  • - quick and from the display guided program installation
  • - language selection directly from display
  • The communication among the various parts of the control is based
  • on the various protocol of communication, either through the line
  • Ethernet (with protocol TCP-IP and UDP-IP) or through the line
  • RS485 with protocol S-BUS, MODBUS, PROFIBUS DP, LON
  • WORKS). This allows a wide flexibility as well as the integration of
  • many different needs and of the future updating as far as the
  • Building Automation is concerned.
  • The PLC is equipped with 2 electronic cards, which can be further
  • extended to 4. It is also possible, when specifically required, to install
  • a further PLC equipped with 16 cards. For any future need, the
  • system can be integrated with other cards, which can be directly
  • connected to the communication line.
  • Whenever required, it is possible to control the drying process
  • directly from the screen, as well as having any anomaly pointed out.
  • The diagram of the specific actuators, in particular of the different
  • sensors (opening of the valves, opening of the chimneys, fans use
  • percentage, spraying..), and of the quantities measured (temperature,
  • gradient, UGL, ) can be directly controlled on the touch screen .
  • All these parameters can be either transferred to a PC and shown
  • with a Scada software, or can be recorded on a CF card and analyzed
  • by a remote PC. The touch screen is equipped with a port for printer
  • and a port for the bar code reader.
  • When programming the drying cycle, this can be divided into 20
  • phases: all freely programmable. For any phase, the following
  • parameters can be shown: air speed, water temperature, hot water
  • volume, electric power used, inverter functioning according to the
  • climatic conditions within the cell.
