Description
This simple flame relay was a favorite of the industry for decades. Kromschröder has replaced this product with FDU, but please be aware of the differences between these products, both in physical dimension and in capability. If you’d like help upgrading to a current product, or if you’re in the market for a new control system, please Contact Us. The more details you can provide, the better! Electrical prints showing the IFW 15 wired in the system would be a tremendous help and may avoid costly site visits.

Applications (click on image for close-up view)
Flame control with flame rod
An alternating voltage is applied between the flame rod, which projects into the flame, and the grounded burner. As soon as the flame is established a small current flows through it and is rectified by the flame. The electronic amplifying stage detects only this direct current signal which, after amplification, is used to energize a relay. A flame cannot be simulated.
Flame control with UV-detector
The UV-detector mainly consists of a tube which is sensitive to light and of electronic components. The tube responds to the ultra violet (UV) radiation from a gas flame, it does not react to sunlight and light from filament lamps.
