Mobile Recirculation Fumigation Unitza03

For gas-tight structures with aeration ducts, including retrofitted ones. All pipework is stainless steel — corrosion resistant and cheap to maintain. Each inlet has a flow-regulating valve, each branch has a test port for airflow and concentration, and the unit has its own port for measuring concentration during the run. A pre-fitted connection accepts an external phosphine generator or a PH₃/CO₂ cylinder so dosing happens outside the bin.
