SPX Cooling Technologies Introduces MarleyGard Water Management Products

SPX Cooling

Overland Park, Kan. – SPX Cooling Technologies, Inc., a full-line, full-service industry leader in the design and manufacture of cooling towers and other specialized heat exchangers, introduces the MarleyGard™ CD Chemical Delivery System and MarleyGard SP Basin Sweeper Piping System.* The preassembled MarleyGard CD and SP Systems install quickly and help maintain cooling tower water quality.

The MarleyGard CD Chemical Delivery System uses electronic monitoring to evaluate the delivery of cooling water treatment and its effectiveness in keeping the control parameters within specified limits. By using this type of control, a technician is dispatched only when problems requiring on-site resolution are encountered. Primary monitoring targets typically include conductivity, oxidation reduction potential (ORP), treatment chemical concentration levels, general water analysis, and corrosion coupons and probes.

As cooling tower operations vary by site and water conditions, quality guidelines, chemical specifications and other circumstances, the MarleyGard CD Chemical Delivery System provides multiple, configurable options for certified water treatment professionals to work the MarleyGard CD control panel. The basic panel includes a controller, conductivity probe, chemical pumps and injection ports. Additional options offer a communication controller, solenoid and blowdown, corrosion rack or corrosion meters, and more. The MarleyGard CD System also provides easy-to-use set points, calibration and timers.

To complement the chemical delivery system, the MarleyGard SP Sweeper Piping System uses nozzles to “sweep” solids toward the sweeper outlet suction pipe, discouraging the formation of biofilm, scale and corrosion. The suspended solids travel through the pump suction pipe to a separator or filtration equipment (supplied separately), where they are removed and clean water is pumped back to the basin via the PVC piping and nozzles. Turbulence created by the nozzles further inhibits biological growth.

Implementing effective water management plans is an essential part of cooling tower operations. MarleyGard water management products maintain and protect cooling towers by helping to minimize conditions that can lead to biological growth, corrosion and scaling.

*SPX Cooling Technologies designs and manufactures cooling towers and other specialized heat exchangers, and provides water management products to support the execution of an effective water management plan (WMP) as outlined in ANSI/ASHRAE Standard 188-2015. Professional water treaters should be consulted to perform chemical delivery services.
