Kromschroder Air/gas ratio control GIK15R02-5 03155170

The Kromschroder GIK15R02-5 is an air/gas ratio controller with an Rp 1/2" internal thread and a nominal diameter of 15 mm. It operates with a maximum inlet pressure of 200 mbar and a pressure range of 0.2–119 mbar. Designed for natural gas, LPG, and air, it maintains a 1:1 gas/air ratio with a turndown of 1:10. The controller features zero shut-off, inlet pressure compensation, an impulse connection, and an outlet pressure test point. Its compact size and easy installation make it suitable for burner systems. It is EN 88 and CE certified, and made in Germany.

Parts of this type are selected by connection size, pressure range, and control type (pneumatic or electronic). Compatibility with the burner's fan characteristic and the gas valve linkage is essential. During installation, ensure the pneumatic impulse lines are clean and correctly connected to the fan pressure tap and the gas valve diaphragm. Incorrect ratio setting can cause incomplete combustion or flame instability.
