About b-Cat

• Cultural heritage: conservation and preservation

• Sport: High Altitude Climate chambers

(official Olympic supplier)

• Food: naturel fumigation

Specialized in low oxygen applications

ZerOx The most (cost-)effectivealternative for

Methyl Bromide

ZerOx• 100% mortality of insects

in all development stages (from eggs to adults)

• by reducing oxygen (O2) in a gastight room to extreme low level:

less than 0,5%

ZerOxBy:• Circulating air inside and

‘scrubbing’ the oxygen to less than 0,5%

• Reducing relative humidity

• Keep temperature above 20oC

ZerOx ….how it works?

Insects & mortalityAll common products and insects

can be treated with ZerOx:• Grains• Nuts• Spices• Dried fruits• Seeds• Tobacco• Cocoa beans• Coffee• Artifacts

• Maize weevil• Grain Beetle• Rice weevil• Wood borers• Flour mite• Indian Meal Moth• Tobacco Beetle• etc.

• 100% non-toxic treatments

• No residual chemicals

• Friendly for the environment

• Eradicates insects in all development stages

• Prevents growth of aerobic pathogens such as moulds

i) Treatment rooms

Most common solution:- Big volumes (any size)- Low cost per treatment- Treatment period

between 2 to 8 days- Well isolated and

gastight rooms

• 100% non-toxic treatments

• No residual chemicals

• Friendly for the environment

• Eradicates insects in all development stages

• Prevents growth of aerobic pathogens such as moulds

ii) Palliflex system

Common solution forlimited volumes:- Bags can be dimensioned

to customer needs- Up to 100 bags with 1

control unit- Controlled individually- Allows removal of

product without disturbing others

- Strong, lasting and flexible gastight cover

Palliflex

Connecting tubes with quick-couplers, enabling automated gas analyses and circulation: perfect control in each cocoon

The b-Cat controller is able to handle 100 Palliflex systems on only one controller.

Controlling tubes for Controlling tubes for the palliflexthe palliflex

Palliflex system

iii) Big bags- Fumigation can occur

during transport- Quality insurance and

protection of foodstuff until bag is opened

- Transport and storage under hyper low-oxygen level

- Reusable

• 100% non-toxic treatments

• No residual chemicals

• Friendly for the environment

• Eradicates insects in all development stages

• Prevents growth of aerobic pathogens such as moulds
