CONTAMINANT, CORROSION AND ODOR problem of CORROSION in industrial envi-ronments, such as refineries, pulp and paperplants, and chemical factories, is as old as theindustry itself.

4 Unlike hard CORROSION , whichcauses physical degradation of equipment,soft CORROSION attacks the process CONTROL sys-tems with minimal visual signs. Operationsmanagers have long realized that electroniccomponents are at the mercy of the gases,acids, and impurities that such environmentscontain. As a result, CORROSION of these compo-nents causes production stoppages, lowerproductivity, increased production costs, andhigher maintenance more than 40 years, Circul-Aire has been a recognized leader in the reduction of gas-phasecontamination, more precisely, in controllingcorrosion and odor potential in commercial andindustrial environments.

5 Museum and hospitalenvironments have all benefited from precisionenvironmental CONTROL techniques developed by Circul-Aire. Circul-Aire s reputation has beenbuilt on years of research and development, and on a growing number of satisfied customersworldwide. The problem of CORROSION is never caused by asingle factor, and cannot be resolved by a singlesolution. Circul-Aire s team of experiencedchemists and engineers, and the firm's affiliationwith ISA*, ASHRAE**, and IEEE** have enabledCircul-Aire to successfully develop an optimalapproach to CORROSION CONTROL .

6 Circul-Aire s unique systematic method, basedon experience gathered from installationsworldwide, is effective for all types of industrialand commercial environments. Circul-Aire sintegrated approach, which comprises four dis-tinct stages (diagnose, measure, CONTROL , opti-mize)can be undertaken progressively, witheach stage constituting an integral segment ofthe overall STANDARD CLASSIFICATIONS:G1 - MildAn environment sufficiently well-controlled such that CORROSION is not a factor in determiningequipment - ModerateAn environment in which the effects of CORROSION are measurable and may be a factorin determining equipment - HarshAn environment in which there is a high proba-bility that corrosive attack will occur.

7 Theseharsh levels should prompt further evaluationresulting in environmental controls or speciallydesigned and packaged - SevereAn environment in which only specially designedand packaged equipment would be expected to the environment to accurately de-termine the extent of its CORROSION s Reactivity Monitoring Service(REMO) is a proven method that produces anormalized one-month evaluation of a givenenvironment's CORROSION coupons contain pure copperand silver strips that react with the environ-ment when installed in strategic areas for periodsof 30 to 90 days.

8 After exposure, the couponsare analyzed to determine film thickness andchemical composition. The data is used todetermine the normalized one-month value forISA classification (G1 to GX), and further usedto determine chemical media (MULTI-MIX )selection. The silver coupon is also analyzed to evaluate the presence of chlorine andhumidity monitoring is available on a real-timebasis, without requiring prolonged exposureperiods. The SURVEYOR PLUSTMis a corrosionmonitoring system providing constant surveil-lance of the environment, indicating the potentialdeterioration of electronic equipment.

9 The SURVEYOR PLUSTM provides real-time environ-mental data to allow for corrective measuresbefore irreversible damage s Sealing Integrity Verification (SIV)measures the protected area where processcontrol equipment is located. Building enclo-sures can never be perfectly sealed. Often, leak-age allows contaminated air to infiltrate into theprotected space in significant quantities, even tothe extent of preventing the required roompressurization. The blower door apparatus measures bothroom differential pressure and airflow pressureto determine leakage profiles.
