2. About b-Cat Specialized in low oxygen applications • Food: naturel fumigation • Sport: High Altitude Climate chambers (official Olympic supplier) • Cultural heritage: conservation and preservation

3. ZerOx: Safe & 100% effective for treatment and conservation

4. ZerOx treatment • 100% mortality of insects in all development stages (from eggs to adults) • by reducing oxygen (O2) in a gastight room to an extreme low level: less than 0,5% • While maintaining Rh at optimum level at +2% range

5. ZerOx….how it works? • Meticulous control of Rh at +2% • ` • 100% non-toxic treatments • No residual chemicals • Safe for all materials • Avoids ageing, corrosion & • generally oxidations • Eradicates insects in all • development stages • Prevents growth of aerobic • pathogens such as moulds • Fungi static • Individual settings possible for each connected room

6. What is needed? An airtight room or space: ZerOx: depot treatment chamber container tent showcase ‘palliflex’ bag tailor-made wrapping

7. ZerOx: What is needed? ZerOx equipment: - Oxygen scrubber - Humidifier - Microprocessor & Controller - Temperature control & senors

8. ZerOx: Meticulous control • Controls up to 100 different rooms, showcases or bags • Every room or bag can have its own settings (Rh, O2, 0C) • Constant data reading & logging (per min, hour or day) • Remote monitoring • Stand alone possible • Online monitoring & alarm system All materials have their own optimum conditions

9. Summary of advantages ZerOx: • Both for conservation as well as treatment purposes • 100% mortality of insects in all development stages • 100% non-toxic, no residual chemicals • Meticulous control of Rh at + 2% in each room • Safe for materials • Avoids ageing, corrosion & generally oxidations (if under low oxygen conditions) • Fungi static, prevent growth of aerobic pathogens such as moulds • Individual settings possible for optimal climate conditions in each connected room

10. ….more advantages • Significant savings can be realised on restoration & maintenance cost • Irreversible damage can be avoided • The central control unit and oxygen scrubber can be used for up to 100 connected rooms, showcases, bags etc. • Online monitoring & alarm system of all conditions & parameters • Can be used as FIRE PREVENTION, no sprinkler installation required in e.g. depots

13. Layout of depot Dimensions for the climate controlled depots can fully meet the needs of the clients Every dimension can be realised from 1 m3 to > 1.000 m3. Width, depth and height are being determined in consultation with client

14. Layout of depot

15. Specific details • Rh between 15 en 99%; • Oxygen levels between 20,8% and 0,03%; • Registration per minute, hour or day; • Automatic calibration • Capacity oxygen scrubbers available from 2 to 85 m3/h • Low maintenance & operating cost

16. Fire Prevention • No fire can occur when oxygen level is less than 17% Internationally recognised method of fire prevention Absolutely safe for workers
