Equipment and Accessories

Our high quality portfolio of metal phosphide containing fumigants is completed with valuable equipment and accessories, which every skilled technician should use during a fumigation.

Respiratory protection, suitable filters, test tubes, gas testers and detectors, fumigation sheets, etc. are important accessories for all persons involved in a fumigation. Safety of workers and environment as well as the supervision of a proper fumigation are secured this way.

Detia Freyberg Automatic Dispenser

The Detia Freyberg automatic dispenser is designed for automatically dosed addition of Phostoxin, Magtoxin tablets and pellets to the grain stream. The modern, economic method of grain and feed insect pest control in silo cells.

The dispenser doses the fumigant into the commodity/feedstuffs that needs to be fumigated in pellet or tablet form (PHOSTOXIN or MAGTOXIN) thereby guaranteeing even distribution which in turn serves to protect the stored goods and improve the quality.

Mode of action:

The Automatic dispenser simplifies the fumigation technique and can easily be installed in virtually all silo complexes. It ensures a uniform distribution of Phostoxin or Magtoxin Tablet and Pellet within the grain.

The automatic dispenser may be mounted in various locations. The most suitable one are:

  • At the manhole of the silo bin to be filled
  • At the point where the main receiving elevator discharges grain into the headhouse conveying system


The device is packed in a 45x46x75 cm carton


1 automatic dispenser with electric switch, 3 dosing plates and 10 m cable.


Phosphine is also highly toxic to humans and warm-blooded animals. It is therefore absolutely necessary to comply with the relevant safety measures.


This circulation system controls precisely dosed and uniform air exchange within the grain mass in every storage facility, regardless of size and construction type. This ensures controlled release of phosphine from the Detia Freyberg fumigants in gas-tight buildings. It is intended for use mainly in silo cells and on ships. The Detia Freyberg J-System is easy to install and operate. It can even be adapted to structures with no ventilation system.

Advantages of the Detia Freyberg J-System:

Reduces the phosphine exposure level of fumigation technicians during the procedure.
Faster and more uniform phosphine distribution.
Pests are killed more rapidly.
No additional costs for shifting of the grain mass.
Avoids the damage to grains caused by shifting of the grain mass.

Product specifications:

Motor: ½ PS • 1 PHASE • 60 Hz • 115 / 230 VOLT • RPM – 3450 • Spark resistant
Duty: Continuous at 40°C ambient • Thermally protected
Explosion proof: Class I Group C, D / Class II Group F, G
Certification: CE approved

Mode of action:

Instead of placing the fumigant inside the grain mass, it is applied on the surface of the pile. After a brief delay, outgassing of the phosphine begins in the empty space above the grain mass surface. After the J-System is activated, the air above the surface of the grain mass is sucked off and blown through a pipe into the grain mass. This ensures uniform distribution of the phosphine gas in the entire storage unit within a short period.

This process is continued until the fumigant has outgassed completely. Reliable insect mortality is ensured by circulation of the gas and the resulting uniform gas distribution in the entire grain mass.

Products containing both, aluminum phosphide and magnesium phosphide, can be used.
