About our Sulfurous Acid Generator

The D&J Harmon Company of Bakersfield, California pioneered the technology of on site generation of sulfurous acid for agriculture in the 1950’s; John Harmon continues the manufacturing process there today.  The Harmon Systems International sulfurous acid generator, aka sulfur burner, always has been and continues to be the leader in the industry.  The Harmon Systems international generator is reliable and durable with examples of 40 year old machines still in use in the central valley of California.
