MC-2000 automatic control unit for wood dryers (drying kilns) is a device that automatically controls drying process in high capacity conventional kilns or dehumidifying (condensing) kilns. NIGOS-elektronik used its experience gained over the years as manufacturer of automatic controllers for wood dryers to further improve automatic controllers. MC-2000 is currently most advance model from NIGOS-elektronik product line of automatic controllers for wood dryers (drying kilns).

This device is based on older automatic control unit MC-1000P. It also has Aluminium case and is delivered already fitted in power electric switch board.

This controller has newest concept of temperature, EMC and wood MC data aquisition applied. MC-2000 standard configuration includes 2 measurement boxes DS-04 attached to measurement module MKM-08 which transfers data via communication line to MC-2000. MKM-08 box can be placed at distance of up to 300 m away from MC-2000 controller which is very suitable for systems with large number of dryers where automatic controllers are placed in one controll room while actual dryers are at distance.

Picture bellow show connection of MC-2000 with MKM-08 and DS-04 boxes.

MC-2000 controlls air temperature and humidity in order to achieve optimum conditions for wood drying inside the chamber. MC-2000 controls its relay outputs automatically, semi-automatically or user can do it manually based on data obtained from temperature and EMC probes (in 2 points) and wood MC probes (obtained from 8 points). Also, control of drying process is adjusted according to other settings set by user.

In automatic operation mode, MC-2000 follows chosen drying schedule (regime). There are 12 invariable (built-in) schedules which are inserted in unit's memory by "NIGOS" during production and which can not be changed. In addition, user can make his own regimes and store it in additional 8 free slots. Beside selection of the regimes themselves, user must select 1 of 4 available wood types as well as timber thickness in range 20 to 80mm in steps of 1mm. Automatic controll units from other manufacturers have predefined regimes for each of these situatons. In case we would make comparesment in such way using only 3 standard thickness (instead of available 60), we can claim that this controller has more than 200 drying regimes as other manufacturers such as Holzmeister and some italian manufacturers present. 

In semi-automatic operation mode user set the desired values for temperature and EMC based on personal experience and measured wood MC and automatic control unit MC-2000 only maintain this values inside the chamber.

In manual operation mode, buttons on the right side of device labeled with OUTPUTS are used. These buttons give the user an ability to manually control heating, drying, fans operation and spraying. While in manual operation mode, MC-2000 only displays measured values for T, EMC and MC, but it has no influence on the relay outputs and equipment inside the chamber. User himself must control temperature and humidity by pressing the appropriate buttons. 

After power failure, if it was started, drying will automatically continue when power is reconnected starting from measured wood MC.
Automatic control unit MC-2000 is delivered with following equipment included (standard configuration):
  • Automatic control unit MC-2000: 1 pcs
  • Measurement module MKM-08: 1 pcs
  • Measurement box DS-04 with fitted temperature probes: 2 pcs
  • EMC paper holder which is fitted on DS-04 box: 2 pcs
  • EMC paper in quantity sufficient for 2 years drying: 1 set
  • Set of wood MC probes for different wood thickness: 1 set
  • FEP insulated cables for boxes connection: 20m
  • Communication cable for MKM-08 to MC-2000 connection: 50m
  • FEP insulated cables for wood MC measurement: 8m x 8 pcs

Warranty for automatic control unit MC-2000 is 5 years.

Upon special user request, or when neccessary for specific dryer, additional eqipment is delivered. This includes wood MC cables in different lengths, measurement/verification equipment for wood heat treatment (palette sterilization according to ISPM-15 standard), RS232<->RS485 adapter for connection of controller to PC with all neccessary cables, installation CD with survailance/verification software etc...
