Annual Pressure Test

Pressure testing a silo ensures it can maintain gas concentrations at sufficient levels to kill all insects at all life stages. Although a silo may be sold as a “sealed silo”, this does not automatically mean it’s suitable for fumigation. Gas-tight seal status can only be proven with a pressure […]
