In late 1997 Degesch America, Inc. brought the first phosphine generator, developed by Degesch de Chile, to the United States.  Degesch America, Inc. took the idea of the Chilean generator, improved on the design, and today makes available the Degesch Phosphine Generator (U.S. Patent # 5,820,840).  This new generation of phosphine application equipment is "Made in the USA"  using state of the art electronics and heavy duty parts.  We have engineered into the Degesch Generator additional safety features and alarms that allow the operator to closely monitor fumigant application.  The Degesch Generator is designed to run automatically once programmed by the operator.  Sensors located throughout  the Degesch Generator monitor designated parameter levels and alert the operator of any discrepancies.  The Degesch Generator comes with a manual pre-fumigation check system that verifies the operating condition of the unit.

The Degesch Generator is able to produce high concentrations of PH³ by using a 94% technical grade of magnesium        phosphide (Degesch Magtoxin^â Granules).  A small amount of carbon dioxide (CO²) is used to create an inert atmosphere inside the reaction chamber.  The  CO² also acts as a propellant to move the Degesch Magtoxin^â Granules through the unit.  The Degesch Generator uses a 100 cfm internal recirculation fan to draw air from inside the structure, mix it with phosphine and return it to the structure. This eliminates pressurization of the fumigated structure that occurs with conventional “injection” style fumigations.  The Degesch Generator is capable of  reacting about 3,000 grams of Degesch Magtoxin^â Granules in one hour.  This equates to approximately 725 parts per million (ppm) throughout  a 100,000 cubic foot storage. 

The Degesch Generator is designed to produce high levels of hydrogen phosphide (PH³⁾ in a short period of time from outside of the structure to be fumigated.  By doing so, we are able to reduce potential worker exposure.
