VAPORPH3OS phosphine fumigant is a cylinderized source of 100% phosphine for use in the fumigation of post-harvest products or storage structures.

VAPORPH3OS phosphine fumigant is designed for use in conjunction with Solvay-approved blending equipment capable of diluting the phosphine concentration to below its lower flammability limit of 3% (vol.) On-site blending with carbon dioxide (CO2) as a dilution gas can achieve this result. This option is well suited for locations that already have on-site storage of liquid CO2or sites where CO2 can be transported easily. The on-site blending of VAPORPH3OS is also an attractive option when frequent fumigation is required. It is also well suited in locations where centralized dispensing stations are feasible.

VAPORPH3OS phosphine fumigant can also be used with Solvay-approved blending equipment capable of diluting the phosphine concentration to below its lower flammability limit of 1.8% (vol.) in air. On-site blending with the surrounding air as a dilution gas can achieve this result and eliminates the need for a bulk source of CO2 for on-site blending. The resulting mixture of phosphine and air that is dispensed from the blending equipment can be added directly to the fumigation space or existing recirculation systems. The on-site blending of VAPORPH3OS phosphine fumigant with air is an attractive option when frequent fumigation is required. The portability of the blending equipment gives the fumigator flexibility in usage at multiple sites. It can also be installed at locations where centralized dispensing stations are beneficial.
