Air Borne Contamination is an undesirable by-product of the changing lifestyles of mankind. Greater demand for more efficient products and services has led to rapid industrialization, which in turn has put excessive pressure on the environment into accepting higher than safe levels of pollutants that it can safely eliminate.
Atmospheric air, especially in manufacturing industry, is contaminated with gases like hydrogen sulphide (H2S), sulphur dioxide (SO2), nitrogen oxides, chlorine, ammonia, mercaptans, hydrocarbons, etc. This contaminated air inside the manufacturing set-up, speed up corrosion and leads to frequent failures of electrical and electronic components of several nearby machinery and sophisticated control systems. Similarly, combustion of fuels by several automobiles also leads to contamination of outside air with gases like SO2, H2S etc. Along the same lines, enclosed commercial establishments also generate contaminant gases from tobacco smoke, paint and furnishings, printers, food preparations, etc.
This contaminated air poses several risks and challenges to increasingly sophisticated and miniaturized electronic devices of all kinds. Our lives and business have increased dependence on electronic devices like servers, drives, control devices, etc. The filtration of contaminated air should not be ignored as it can lead to problems like increased downtime, hardware failure and stoppages, loss of productivity, etc. in the long run. Corrosive gases cannot be just filtered through simple air filtration systems. Therefore one needs a specially designed solution to neutralize these gases. Gas Phase Filtration System is one of its kind which works effectively and efficiently and proves as a strong barrier and control system for air borne contamination.
Bry-Air Ecoscrub Gas Phase Filtration System provides the ideal and most cost-effective solution for air borne molecular contamination. Its unique process not only cleans the contaminated air of suspended particles and corrosive gases but is also used for odour removal, making the working environment healthy for you and your electronic equipment.
Bry-Air Ecoscrub Air and Gas Purification System is ideal for industries as diverse as :
The process of air filtration is simple. The contaminated air first passes through pre-filters which trap the suspended particles, and then through the required chemical media beds, which chemically destroy or retain any remaining gaseous impurities. The chemical media can be activated carbon and / or activated alumina impregnated with proprietary chemicals, used alone or in combination – depending on the types and concentrations of the impurities present in air stream. Bry-Air EcoScrub System is designed to operate and maintain contaminant gas levels at 1 ppb (parts per billion) or less.
Bry-Air offers various types of Air and Gas Purification Systems depending on the method of purification and known parameters related to airflow, types and concentrations of impurities present in air, space availability and desired media life. The following systems can be selected:
Deep Bed Systems Deep Bed Systems – These Essentially consist of either single or multiple, perforated, hollow housing(s), also called bed(s) filled with chemical media, of at least 305 mm (12” or 1’) thickness. These beds are placed perpendicular to the direction of flow of air. Deep Bed Systems are used for ‘pressurization’ applications in industry, wherein level of air borne contamination is very high and good quantity of media holding is a necessity for prolonged uninterrupted use, before media gets completely spent and replacement becomes inevitable. Deep Bed Systems are powered units of horizontal configuration.
Thin Bed Systems Thin Bed Systems – These consist of either single or multiple stages of hollow, perforated, retractable ‘V’- shaped module(s), also known as cassette(s) filled with chemical media, of either 25 mm (1”) or 75 mm (3”) thickness. These cassettes are placed in the path of airflow. The other major parts include a set of pre-filters, final filters, fan/blower assembly and control panel, other than pressure-drop measuring gauges.
Thin Bed systems are used for ‘re-circulation’ applications in Commercial / Industrial sector, as well as for ‘pressurization’ in industrial environment where air contamination levels are on the lower side. Media holding capacity and pressure drops are smaller than Deep Bed units, in this case. Thin Bed systems can be powered as well as un-powered units of both horizontal and vertical configurations.
