Burner Technology of Schwank Infrared Radiant Tube Heaters

Whisper-Jet premium class burner

The Whisper-Jet burner is the core of Schwank tube heaters. Its design is the result of decades of experience in dealing with gas-fired infrared radiant heaters and the constant striving for further technical advancements.

During the engineering phase, state-of-the-art technologies and know-how have been adopted and applied. For instance, a pressure fan was installed providing the advantage that the flow characteristic of the gas-air-mixture is easier to influence in order to achieve a better and more uniform heat distribution. In addition to this, components, such as the fan and its ball bearings are not exposed to the hot flue gas. This contributes to a longer life of these parts.

By means of various simulation tests, CFD [computational fluid dynamics] tests and the use of a patented Schwank ceramic burner tile, Whisper-Jet produces a very long and laminar flame. The axial flow distributes heat more uniformly over the entire length of the tube.

Whisper-Jet is an exceptionally quiet burner. With approx. 46dB[A] at 10 feet [3m] distance, you hear no more than a soft whisper.

An optional 2-stage burner controls operation to better match actual heating requirements. This saves resources and lowers operating costs.
