CONTROL ACCESSORY TYPE: RZ

  • Connection to Rekumat burners (RB) or Rekumat radiant tube burners (RS)
  • Screw type or mounting rail fastening
  • Overtemperature input
  • Power dosing input
  • Adjustable burner on time
  • Function display by LEDs

The Control Accessory is used in connection with a Rekumat burner (RB) or Rekumat radiant tube burner (RS) to calculate the switch on time of the built-in twoposition controller in the controlled member.

The ON time of the burner corresponds to the process conditions.

The control accessory is equippedped with a microprocessor that calculates the power requirements.

Different function versions are available.
