Series Overview
The Kromschröder GIK Series gas/air ratio controllers keep the gas and air pressures in a constant 1:1 ratio. This provides stable combustion across modulating and staged burner systems.
Key Features
- 1:1 Pressure Ratio: Maintains proportional gas/air pressure for consistent flame quality.
- Control Modes: GIK for continuous control, GIK..B for high/low/off staged control.
- Wide Size Range: DN 15 to DN 150 for small to large industrial burners.
