The power supply unit is located in a sealed box. The box is adapted to be fixed at the place of use.

On the side wall of the STZ-6 there is a power socket with a special pin.

There is an on / off button located on the external door of the STZ-6:
– (start – green, stop – red);
STUNNING LAMP – red indicator light;
ALARM LAMP – yellow indicator light;
– Digital display of stunning voltage, stunning current and frequency (x10);
PIG820 stunning parameter control panel and stunning parameter recorder;
– Inspection window with SD card slot and fuse socket.

The device automatically measures the resistance and, based on the guidelines (included in the parameters set in the PIG820 slaughter parameters), selects the correct current values ​​(during slaughter) in order to carry out the correct stunning cycle.

The STZ 6DW sunning device should be connected to a mains power supply made of copper conductor with a cross section of no less than 1 mm2.

Water bath for stunning fish supports STZ 6DW/R device. It allows to stun fish with a total weight up to 200 kg in one time. Developed in the KOMA company alternating current system between the electrodes guarantees 100% stunning efficiency, irrespective of fish direction. Water bath housing is made of tight, high impact plastic.

KOMA water bath for stunning fish is completely safe. It is equipped with a safety feature which allows the stunning process to take place only when the water bath lid is firmly attached.

  • stunning parameters numeric display
  • voltage or current and frequency adjustment during the stunning process
  • 6 stunning programs (possibility to change their parameters by the user)
  • changing stunning program with one button
  • recording of work parameters

Stunning parameter recorder


The recording device fulfills the requirements of the Council Regulation No. 1099/2009 of 24 September 2009. (Annex II, point 4.1) on the protection of animals at the time of killing.

The recorder device is factory-installed in the STZ 6 DW stunning device. During stunning process, the recorder performs the measurement of electrical parameters related to the slaughter and saves these parameters ​​on the SDHC memory card located in the recorder socket.
