FLOTRON Smart Flow Controller


QualityThe stability of gas flow is controlled automatically, making the flame more stable, the defect rate is reduced, the CPK and the brazing qualification rate is improved.

Cost downStrong and weak flame switching function. The weak flame flow load is 1/4 - 1/6 of strong flame flow load. While waiting parts to be welded,strong flame turns to weaker flow load and this will reduce the usage of oxygen and gas.

SafetyIn any case of shutdown or power off (including sudden power failure), DF11K will automatically trigger the nitrogen fire extinguishing device to automatically extinguish the fire and prevent flashback, so as to ensure the safety and reliability of the whole system.

Digitalization:With digital control, the flow setting is intuitive and convenient.
