Description

The IFR 50 is a UV Flame Scanner Compact Version that has been specially developed for difficult conditions that often occur in industrial applications for single flame combustion. The IFR 50 can be connected directly to the ionization or LDR input of the control box. The UV sensor ensures that the Flame Scanner Compact Version does not react to background radiation from hot refractory material or any other infrared light source.

The UV Flame Scanner Compact Version must be switched off once a day. For safety reasons and technical regulations, the burner must be switched off at least once every 24 hours.

The IFR 50 UV Flame Scanner Compact Version was developed to meet the requirements of UL 372-2, CSA C22.2 and EN 298. The internal increase of the UV tube voltage by 15 % during the starting phase ensures the safety requirements for testing the UV tube until ignition. The IFR 50 UV Flame Scanner Compact Version must be switched off for longer than 5 seconds before burner operation can be resumed.

The UV Flame Scanner Compact Version is equipped with an optical interface that visibly displays the intensity of the flame signal. A simple diagnosis of the flame intensity is possible directly on the furnace boiler. The optical interface can also be visualized with the UVT-COM module of the BST-COM software.
