Degesch America, Inc. has acquired the rights to produce the “original” J-System® B-9 recirculation blowers. The new company, J-System Recirculation, LLC will be headquartered in Weyers Cave, VA.

Weyers Cave, VA – March 22, 2016 – Degesch America, Inc., is pleased to announce the formation of J-System Recirculation, LLC. The new company will assemble the original B-9 and A-3 J-System® Low Air Flow Fumigation Method blowers at its facility in Weyers Cave, Virginia. These models have long been considered the gold standard for the fumigation industry.

The blowers provide low volume recirculation of fumigant throughout a grain mass; most commonly used for in-transit fumigation of grain cargos on bulk carrier vessels. Additional applications include farm tank or bin fumigation, air evacuation, moisture control, and others.

The original blower was developed by Jim Cook, of J-Chem, Inc. to complete his patented J- System®. The initial application was used for farm storage treatments. While under pressure from importing countries, the USDA was researching an improved bulk carrier fumigation method. In a trial treatment performed in 1987 on the M/V Gamel Abdal Naser, the J-System’s effectiveness was clearly demonstrated, which led to the incorporation of the recirculation method into the FGIS’s Fumigation Handbook. Degesch America, Inc. acquired the rights to the method through the acquisition of J-Chem, Inc. in the late 1970’s.

Quality remains our top priority!
