Inquiry (采购产品): Cooling Tower Sand Filtration System I would like a quote for adding a sand filtration system with automatic back wash to our cooling towers. We have three Marley cooling towers with approx. 6300 gallons of sump capacity. System capacity is around 9000 gallons. I would like to install either (1) system to handle all three towers, or three individual systems. Please quote both.
