October 18, 2007 — /IEST News/ — ARLINGTON HEIGHTS, IL — A newly revised Recommended Practice (RP) from the Institute of Environmental Sciences and Technology (IEST) covers the design and testing of modular gas-phase adsorber cells in single pass or recirculating air-cleaning systems where the need for high-efficiency removal of gaseous contaminants is a requirement. IEST-RP-CC008.2: High-efficiency Gas-phase Adsorber Cells discusses three types of modular cells in detail, including new material on Type IV (vee-bed) cells.
The RP incorporates allowable materials, design, construction, quality assurance requirements, and packaging and shipping for adsorber cells. Appendixes in the document cover recommended installation requirements, calculation of residence time of adsorber cells, and recommendations for ordering, marking, and shipping.
