DAS UNIQUE BENEFTTS ■ THE CONVENTIONAL SOLUTIONS Traditional solutions used for odor and corrosion problems consist of two types of Systems: wet scrubbers and dry scrubbers. Wet scrubbers are typcally large towers utlizing chemical solutions to neutralize the odors. Thﮨse types of Systems are used in cases of very high concentrations (greater than 20 ppm) in order to reduce contaminant loads. Wet scrubbers require a major investment and substantial maintenance costs. Creul-Aire's Oeep Bed Air Systems (DAS) are smaller dry scrubbers filled with granular MULT1-MIX® mdia. Smaller...

DAS SPECIFICATIONS ■ GENERAL 1.1 Provide a Circul-Are model DAS factory-fabricated gas phase air purification System or equal sutable in design for the removal of both organic and inorganic contaminants as indicat-cd on the schedule and drawing. 1.2 The unit manufacturer shall have been engaged in the fabrication and design of air control Systems for no less than the last ten years. Strict adhrence to sizes and capacities shall be maintained. Any dviation from the sp驩cifications must be approved by the engineer's office no less than ten days prior to the project bd date. No considration of...

DAS SPECIFICATIONS 2.8 Lifting lugs shall be added to the ■rame so the unit can be lifted evenly without deflection. 2.9 Internai and external zinc coated steel surfaces shall be coated with a three-part corrosion rsistant aliphatic polyurethane finish. Applications System shall consist of one prime coat (1 mil minimum) applied over a xylene cleaned surlace followed by two fn鯯shing coats. Each finishng shall be 1 mil minimum. Final coating shall provide excellent rsistance to moisture and traces of acid gases or alkali fumes, sait air or solvent, for tempratures up to 180°F. Standard...

DAS SPECIFICATIONS MM-3O0O The MULTI-MK® MM-30OO shall be UL Class 1 nonflammable and consists of a coal based activated carbon of 1/8" diameter extruded cylinders. Physical adsorption removes the gas molcules, which is a fonn of condensation. Activated carbon is used for a wide range of contaminants with higher affinity to sp魩cifie gases. MM-7000 The MULTI-MIX® MM-7000 is manu-factured in 1/8" diameter extruded cylinders and consists of activated carbon impregnated with phosphoric acid. Phosphoric acid is impregnated into the carbon to provide enhanced efficiency and capacity for alkaline...

DAS SPECIFICATIONS 4.1.C Centrifugal AirfoU Fans (Type SISW) The fan wheel design shaU be of a non-overloading type backward curved double surface airfbil section. The complte fan wheel shall be of welded construction and the wheel and shaft assembly shali be dynamically bal- anced to ANSI Standard S219-1989, Quality Grade G6.3. Fan shafts shall be designed so as to operate at no more than 80% of the first critical speed range. The fan housing shall be constructed of heavy gauge steel suit- able for the CLASS duty. AU seams and joints are to be continuously welded to eliminate leakage. AU...
