The MarleyGard CD Chemical Delivery System is a robust control panel that facilitates delivery of cooling tower treatment agents and monitoring of cooling tower water quality.
The MarleyGard CD Chemical Delivery System is a robust control panel that facilitates delivery of cooling tower treatment agents and monitoring of cooling tower water quality. Professional water treaters should be consulted to perform chemical delivery services.
The MarleyGard SP Sweeper Piping System, installed in a tower’s cold water basin to help remove sediment and debris, discourages “slow-flow” areas and helps prevent biofilm formation and bacterial growth.
Through proactive monitoring and treatment, MarleyGard water management products help cooling tower operators take a proactive approach to challenging issues surrounding scale, corrosion, microorganisms and water conservation.
The MarleyGard CD Chemical Delivery System is an organized and robust panel that is specifically designed to facilitate delivery of cooling tower water treatment agents and reliably controls water chemistry parameters. Its advanced communication center continuously monitors and communicates cooling water conditions – information essential for providers of water treatment services and building operators charged with executing effective water management programs.
The MarleyGard CD is a recommended option for every factory-assembled cooling tower that can help minimize maintenance costs and extend equipment life.
Control System Designed for Cooling Tower Operation.
Key indicators are pre-programmed to simplify setup. Five assignable relays support addition of data inputs to expand controller function.
- Oxidation Reduction Potential (ORP)
- Three biocide and chemical feed pumps
- Four 4-20mA Inputs
- USB for data access
- Internet communications option
The standard chemical delivery system includes the controller, conductivity probe, chemical injection ports and three chemical pumps. For users seeking additional capabilities beyond the basic control system, options include:
- Communications center to provide data via Internet
- Four chemical pumps
- Corrosion monitoring via corrosion coupon rack or LRP monitors
- In-line water meters
- Solenoid blowdown valve
The MarleyGard CD Chemical Delivery System helps ensure that the tower owner and the selected water treatment provider have all the tools needed to automate the treatment program, protect the equipment, maintain proper treatment cycles and monitor the treatment process between regularly scheduled system inspections.
MARLEYGARD™ SP SWEEPER PIPING SYSTEM
Available for Marley Cooling Towers, Fluid Coolers and Evaporative Condensers, the MarleyGard SP Sweeper Piping System, with PVC piping and nozzles strategically positioned around the perimeter of the cold water basin, is compatible with a range of separation or filtration equipment to ensure the removal of solids.
- A pump circulates water that flows from the nozzles through the basin via PVC piping, producing a hydraulic sweeping action.
- The water flow directs solids toward a sweeper outlet suction pipe and into the separation or filtration equipment.
- Clean water is then pumped back to the basin via the PVC piping and nozzles.
- Turbulence created by the nozzles further inhibits biological growth.
Note: 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 treatment providers should be consulted to perform chemical delivery services.
