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.

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.
Often it is necessary to remove iron containing deposits, such as FeO(OH)4, Fe3O4,
FeCO3, 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.
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.
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.
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.
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 30˚-40˚F decrease
in operational temperatures are typical.
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.
