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

ZerOx: Safe & 100% effective fortreatment andconservation

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 ZerOx treatment

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

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

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

ZerOx: Meticulous control Controls up to 100 different rooms, showcases or bags Every room or bag can have its own settings (Rh, O 2, 0 C) 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

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 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 Meticulous control of Rh at + 2% in each room

….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. FIRE PREVENTION, Can be used as FIRE PREVENTION, no sprinkler installation required in e.g. depots Online monitoring & alarm system of all conditions & parameters
