1. 21st century manufacturing technology has enabled further advancement and the introduction of the new Marley Retlex RTM industrial fan cylinder offering a more dimensionally accurate high quality surface finish better fit and robust structural integrity A light RTM resin transfer molding closed molding process lends itself to increased durability for the final product and ensures laminate thickness and weight consistency Because the cavities are infused using rigid forms in the ribs there is no porosity or potential sites for delamination or structural fracture to begin Therefore the cylinder load capacity is greatly enhanced 1 800 462 7539 The green benefit of the closed molding process is the virtual elimination of VOC emissions because the resin is injected and cured in a sealed closed mold And because the lay up process is now dry a more precise laminate can be achieved with no hand working of resin soaked materials no cleaning requirements for application equipment no hand tools using hazardous chemicals and no chemical disposal concerns 41 H3 Fan True twisted airfoil design Solid cast aluminum alloy Infinite pitch adjustment Machined aluminum hub m 54 through 216 diameter Stainless steel hardware standard Cooling Tower Know How Axial fans require only half the operating horsepower of centrifugal blower fans Marley H3 cast aluminum alloy fans are A t

ISCHARGE ANGLE AIR FLOW Marley XCEL Drift Eliminators Marley XCEL drift eliminators discharge air at an angle of 45 to 53 with respect to the horizontal The exact angle depends on the specific eliminator and on the slope of the tower frame The directional changes incorporated in Marley s three pass drift eliminator act as turning vanes to induce the discharge air flow through a gentle turn from the horizontal toward the vertical To be sure of efficient cooling tower performance always demand that drift eliminators in large crossflow towers must provide a discharge angle as defined by the angle of the last section of the eliminator itself at least 40 from the horizontal Otherwise unnecessary and costly turning losses will occur in the plenum gt Marley Some drift eliminator manufacturers overlook this fact and do not include turning vanes on their cellular drift eliminators Serious performance problems can occur because of this oversight R amp D investigations have demonstrated that some cellular drift eliminators in crossflow towers actually reduce thermal performance by 4 to 8 because they direct the discharge air inefficiently Discharge air from some cellular drift eliminators actually enters the fan plenum at an angle below or near the horizontal The fan energy is wasted because it must force the air stream through a turn of more than 90 This resultant increase in pressure loss reduc
