Sealed, gas tight silos
Sealed silos, otherwise known as gas tight silos, are recommended for long term storage of grain.
Sealed silos are a controlled atmosphere that acts as fumigation chambers for effective control of insects at all life stages. A silo is only truly sealed if it passes a five-minute half-life pressure test according to the Australian Standard AS2628. A silo that does not meet the standard will allow gas to leak out. The concentration of fumigant will be reduced, and there is a chance of insect survival.
HE Silos Gunnedah ensures it has met and exceeded Australian Standard AS 2628 of sealed silos. This is done throughout the manufacturing process by:
- Ensuring all seams and joins are sealed both inside and out
- Rubber Seals made of high density on all openings
- Pressure relief oil valve
- Ability to pressure test your silo onsite
- Silos are pressure tested before leaving our factory
HE Silos phosbox for safer fumigation at ground level

Optional upgrade to stainless steel base
