  • Used in conventional, dehumidifying and combined wood dryers
  • Plastic case suitable for wall installation
  • Ideal for operation in systems with several drying chambers
  • Automatic, semiautomatic or manual control of drying process
  • ON/OFF type of control
  • Drying of all types of wood regardless of the starting moisture content and thickness in range 20 to 80 mm

MC-600 automatic control unit for wood dryers is a device that automatically controls drying process in conventional kilns or dehumidifying kilns. It can also be used as a cheeper option for automatic control unit MC-2000.

This device is based on older automatic control unit MC-2000 as cheaper controller for less demanding users. All main functions are included, but it lacks some options such as: PI type of control, archive, real clock and have fewer anlogue / digital intputs and relay outputs.

Device alone is now placed in plastic box suitable for wall mounting which makes installation process much easier. Further more, a newest concept of temperature, EMC and wood MC data aquisition is applied. MC-600 standard configuration includes 2 measurement boxes DS-04 attached to measurement module MKM-08 which transfers data to MC-600. MKM-08 box canbe placed at distance of up to 300 m away from MC-600 controller which is very suitable for systems with large number of dryers where automat controllers are placed in one controll room.

Standard set provide 2 inputs for air temperature and EMC measurement and 8 inputs for wood MC measurement. On request for smaller dryers, it can be delivered with 1 input for temperature and EMC measurement and 8 inputs for wood MC measurement.

Pictures on the right show connection of MC-600 with MKM-08 and DS-04 boxes, as well as enlarged picture of DS-04 box with fitted probes.


MC-600 achieves optimum conditions for wood drying inside the chamber through air temperature and humidity control. MC-600 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). In addition, control of drying process is adjusted according to user settings.

In automatic operation mode, MC-600 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.

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-600 only maintain this values inside the chamber.

In manual operation mode, buttons on the right side of device are used. These buttons give the user an ability to choose manual control of heating valve, servo-controlled flaps and sprinklers for spraying. While in manual operation mode, MC-600 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-600 is delivered with following equipment included (standard configuration):
  • Automatic control unit MC-600: 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-600 connection: 50m
  • FEP insulated cables for wood MC measurement: 8m x 8 pcs

Warranty for automatic control unit MC-600 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...
