Trouble-Free Maintenance & Operation
Maintenance and downtime are virtually eliminated by the careful design of the Whisper Jet burner. The Whisper Jet burner uses the highest quality, field-proven components. Each burner is also fully tested before leaving the Astec burner factory to make start-up at your facility as fast as possible. For the most reliable oil light-off, even under cold and harsh conditions, the Whisper Jet burner is supplied with Astec’s exclusive heating and insulation system on all heavy oil burners.
Low Combustion And Noise Emissions
The Whisper Jet burner uses unique patented technology to burn clean and efficiently. True to its name, the Whisper Jet burner is designed and equipped to reduce burner noise over competitive burners.
Rapidly swirling high energy air is the key to the Whisper Jet burner’s efficient combustion. The swirling air and flame are created by the fixed internal spin vanes and the patented castellated nose, ring, and nozzle design.
