With the development of the FLOX® burner REKUMAT® S, WS has once again succeeded in revolutionizing the recuperative burner. A tripling of the heat exchanger surface due to the patented gap flow technology enables groundbreaking efficiency. Thanks to "FLOX® inside", the burners achieve the lowest NOx emissions even at extremely high efficiency.
Due to the scalability of the recuperator, the burner is always perfectly adapted to the respective application. With efficiencies >80%, the REKUMAT® S achieves the efficiency of a regenerative burner even at lower outputs.
