Pressurized spray system distributes water evenly over the coil. Steel header box with PVC branch arms.
Low-clog polypropylene nozzles—delivers precise distribution of water over the coil area.
Marley's hot-dipped galvanized coil is tested at 2757 kPa to ensure integrity and sloped to ensure total
drainage at shutdown
Marley XCEL drift eliminators—limit drift losses to no more than .005% of the design m 3 /hr flow rate.
■ Structure
Forced-draft, counter-flow design requires considerably less plan area than crossflow fluid coolers typically use.
Series 300 stainless steel or heavy mill galvanized steel construction.
Factory assembled—ensures final field installation will be hassle-free.
Centrifugal fans and a fully-enclosed falling water area create one of the quietest fluid cooler configurations on
the market.

Forward-curved centrifugal fans are dynamically balanced and mounted on tubular steel shafts.
Fans are supported by roller-bearings mounted at both ends with heavy-guage steel supports.
Spherical roller bearings are rated at an L
10
life of 50,000 hours.
Fan guard / Air-inlet screens are 16 gauge galvanized steel.
TEFC Fan Motor—1.15 service factor, variable torque, and specially insulated for fluid cooler duty.
The MC Fluid Cooler air movement package including the structural support—guaranteed against failure for
a period of five full years. The motor is warranted separately by the motor manufacturer.
