Circulation Air Filters

Vadivel Cocotech supplies a diverse array of air treatment carbons for treatment of fresh and re-circulated air for odour control and removal of organic and inorganic contaminants. Our activated carbon products are ideal for use in general ventilation systems or air conditioning in large complexes, underground stations, underwater recreational areas, aircraft, submarine air filtration, and in laboratories. Inlet air in control rooms and other enclosed areas in industries where there is potential contamination of the air by corrosive gases such as sulphur dioxide that can affect sensitive electronic equipment while accumulation of which can be a health hazard also calls for Vadivel Cocotech carbons as a purification solution.

Equipment Air Filters

A multitude of equipment contains air filters for the removal of volatile organics and other contaminant particles found in gaseous streams. Vadivel Cocotech offers diverse products to be used for odour removal, organics adsorption and toxin extraction in kitchen hoods, refrigerators, vacuum cleaners and photocopiers. In addition to our standard granular product range we also offer specialized products for target contaminant removal such as ozone removal. Our products are available in a wide spectrum of particle size distributions to match your pressure drop requirements.

Pressure Swing Adsorption

Pressure swing adsorption technology is used to separate individual gases from a mixture under pressure considering the affinity of a gas species to an adsorbent material and its molecular characteristics. Vadivel Cocotech Activated Carbon products have proven to be ideal adsorbents for this application with very high surface areas ensuring high adsorption capacities and selective adsorption and desorption capabilities at different pressures. Our premium products of this range are used in pressure swing applications in large scale commercial synthesis of hydrogen for removing carbon dioxide, in oil refineries for the removal of hydrogen sulphide, to separate nitrogen from methane gas in methane gas processing plants and in the production of ammonia.

Compressed Air

Compressed air, often used as the fourth type of utility carries contaminants molecules including oil particles. Activated carbon filters is among the filtration technologies used in purifying compressed air/gas. Vadivel Cocotech Activated Carbon Air series offers tailor made products for this application. Our products precision designed to scavenge and remove contaminant oil vapours providing the ultimate protection against oil contamination. In addition the superior adsorption capabilities of Vadivel Cocotech activated carbon allows removal of other micro contaminants present in compressed air proving to be the most effective and efficient adsorption filter medium for compressed air purification.
