Traditional corrosion control methods such as the use of carbon adsorption systems are both capital and maintenance intensive. Aerisa’s innovative approach provides unique technology for corrosion control with much lower total cost of ownership.
A Different Approach
Legacy corrosion control systems take outside air that is heavily laden with the very gases that cause corrosion, pass it through a bed of carbon and deliver this air into the space. Aerisa ionization systems are designed to recirculate air within the space and produce a highly ionized airstream with millions of O2+ and O2- ions per cubic foot. These ions proactively attack the corrosive gases and permanently removes them thereby creating an atmosphere that is corrosion free (G1 as per ISA S71.04).
The Aerisa ionization technology for industrial applications is based on ions produced by an ionization tube. The tube works with single phase AC power transformed to approximately 3,000 volts. The electrical potential created by the tube, along with system airflow, creates positive and negative oxygen ions that form molecular ion clusters with high oxidizing power. Each ionization unit comes with five tubes, with the application-specific quantity of ionizers housed in a free standing air handler.
|Air||Inside air recirculation||Outside air introduction||Recirculation only systems do not put additional demand on existing HVAC systems. Furthermore, outside contaminants are not being introduced.|
|Power||Low power consumption||High power consumption||Aerisa's systems are stand alone units within the space and include a single MERV 8 filter that produces some static pressure. Typical carbon systems have multiple particulate filters, often 2-3 beds of carbon which necessitates very high power consumption to overcome the pressure drop associated.|
|Footprint||Stand alone cabinet on casters||Large metal or FRP tanks located outside the space||Aerisa's units are designed for maximum air velocity through the internal components making it a very small unit. Carbon systems operate at a much lower velocity in order for the reactions to take place. This makes the equipment very large.|
|Maintenance||Occasional Tube replacement||Annual carbon replacements||The cost of ownership of an Aerisa system is a small fraction of that of a carbon system where the carbon needs replacing annually (or semi annually).|
|Spare parts||Fuses, tubes||Filters, carbon||Due to a carbon system's being out doors, filters are in need of repacement quarterly and carbon annually or semi annually. These parts often need to be held in stock and they are expensive and bulky. A few ionization tubes and some spare fuses are all that is required for an Aerisa system.|
|Disposal||Fuses, tubes||Filters, carbon||Spent carbon must be disposed of in a land fill requiring special local approvals, special transportation (potentially classified as hazardous), and special vacuum trucks to remove it from the vessels. Aerisa's tubes and fuses can be thrown away as standard waste (trash).|
|Sound||Low||High||Aerisa's units utilize a very small fan and have very little static pressure to overcome (MERV 8 filter). A typical carbon scrubber, must overcome very high internal static pressure and therefore, utilizes large fans which produce very high sound levels|
