1 Why wait until catastrophe strikes? Prevent the Chain Reaction of Equipment Wear, Maximize Heat Transfer, Protect Equipment Life

2 IAS has pioneered and utilizes a new generation high-velocity, chemical decontamination process. The process ensures that all fluid-wetted system components are chemically treated while executing high-velocity system flush. The process is more efficient and economical than conventional methods; it also minimizes waste and adverse environmental impact. The process ensures only minimal chemical volumes are required, cutting cleaning time, and effluent disposal costs. The effluent of waste fluid stream generated during the decontamination process, once neutralized, is considered environmentally benign and safe for humans and the environment. IAS provides highly trained and certified personnel, dedicated equipment, and revolutionary chemical materials to provide a complete chemical decontamination on the entire system. Real-time analysis will be performed by technicians to ascertain the effectiveness and completion point of the process. This data will be made available upon completion of the project.

8 Inherently Biodegradable Non-Caustic Water-Based Non-Hazardous No-regulated by US DOT Fully Compatible with all common seals and elsatomers including: - PTFE, EMDP, EPR, Buna-N, Rubber, etc. Fully Compatible with all metals including: - Carbon Steel, Stainless Steel, Incoloy, Hastelloy, Brass, Bronze, Aluminum, etc. Due to its non-hazardous nature and inherent biodegradability, this product is almost always acceptable, partially due to its extreme dilution in neutral water and when neutralized to a ph of approximately 6-8, to dispose of as any common water or water run-off would be disposed of.

9 Often it is necessary to remove iron containing deposits, such as FeO(OH) 4, Fe 3 O 4, FeCO 3, etc., from systems constructed of dissimilar metals such as brass, stainless steel and carbon steel. It is also desirable to remove these deposits and passivate the system with a safe and environmentally friendly solution requiring little disposal. IAS chemical cleaning technology has solves the problem since most chemical cleaning solutions capable of both removing the deposits and passivating the system contain ammonia or amines, which may cause stress corrosion cracking of copper and other alloys. These solutions are also typically harmful to the environment, difficult or expensive to dispose of and produce large volumes of waste effluent. The IAS process is unique in the fact that it can be conducted without the expense or danger of heating the process chemistry as it performs well at ambient temperatures. Additionally, the High-Velocity flows, often through advanced filtration, under which the process is undertaken increase the effectiveness of the process.

10 This IAS system is a process for removing iron containing scales, mill scale, water scale, paints, coatings, rust preventatives, grease, sludge and other forms of contamination from fluid and process piping systems. The IAS process is ammonia free, low in chloride and provides both deposit removal and passivation with minimal solution volume. The IAS Passivation component of the process leaves the cleaned surface coated in a one (1) molecule thick layer of passivation, ensuring that the system is protected from blush, rust and corrosion until it can be commissioned or re-commissioned. The process is suitable for removing iron containing deposits from systems constructed of brass, copper, austenitic stainless steels, carbon steels, or any combination of these. This represents a savings in time and effort since systems containing dissimilar alloys may be cleaned without disassembly or fear of ammonia, amine or chloride induced cracking.

11 IAS uses an environmentally friendly cleaning formula that is ph balanced. The low pressure cleaning process will not damage delicate fin fans and completely removes dirt, debris and corrosive elements. Low pressure foam cleaning increases the residence time in the region of interest resulting in a complete and thorough cleansing.

12 Dirty fin fans reduce the cooling efficiency of heat exchangers. IAS low pressure, high volume cleaning process removes dirt and debris safely and thoroughly. Cooling equipment begins performing at optimal levels and the results bring multiple financial benefits. Clean exchangers results in less energy requirements allowing fans to be turned off or run more slowly. Equipment life is extended and most importantly, production can be increased where cooling has been detrimental to output.

13 Dirty fin-fans increase production costs. Heat exchanger units cooling at a slower rate have a dramatic effect on plant production capability and consequently, on the plant s overall performance. One-by-one, IAS unique, multi-step, decontamination process returns each individual heat exchanger to peak performance and facilitates the plant to run at optimal levels. As much as a 70% improvement in heat transfer and a characteristic F decrease in operational temperatures are typical.

14 IAS technicians use an environmentally friendly, multi-stage, chemical foam formula that saturates and expands into every crevice of the heat exchanger. A low pressure rinse minimizes overspray and is safe for both personnel and the equipment. The traditional cleaning method (hydro-blasting) damages delicate fin fans and packs the debris into the center of the tube stack. The IAS Critical Equipment Decontamination process completely removes dirt, debris and corrosive elements without damaging equipment.
