English The SKP55 works as a differential pressure regulator and regulates a gas differential pressure corresponding to an air differential pressure. The ratio of the differential pressures is 1:1 and remains constant over the entire air range. Its areas of application are preferably:
• in combustion systems with downstream heat recovery
• in systems in which the pressure ratios in the burner and combustion chamber do not change proportionally to changes in output
• in burners with adjustable fuel-air mixing device in the burner head
• in systems with a negative pressure level on the gas or air side
Mains voltage: AC 230 V -15%/+10%, 50/60 Hz +/-6%
Power consumption: Max. 10 VA
Protection class: IP 54
