Controlled Atmosphere Technology (CAT) is a safe, effective solution used to treat delicate objects. Items such as museum artefacts, historical clothing, tapestries, antiquities, fragile textiles, paintings, books and antique furniture can all benefit from this treatment.
Objects or commodities are sealed within a specialist polymer membrane bubble – the controlled atmosphere – with extracted air replaced with regulated concentrations of Nitrogen or Carbon Dioxide gas.
This treatment effectively eliminates all life stages of pest insects and leaves no harmful residues on objects. This delicate process can take up to several weeks to effective completion.
Carbon Dioxide fumigation is accepted by The Soil Association – and other verifying bodies – as a suitable treatment of organic food produce such as cereal, pulses, nuts, grains and dried fruits.
Relatively small quantities (1-20 tonnes) of commodities can be treated and several treatments can be carried out simultaneously.

Controlled Atmosphere Technology (C.A.T) is a specialised form of fumigation, relying on the use of either Carbon Dioxide or Nitrogen. It is used when items to be fumigated might be damaged by a more conventional fumigant such as Phosphine.
