Nu-Calgon’s pH-Treat neutralizers address acidic condensate produced by high efficiency furnaces, boilers and water heaters before it goes to drain. If left untreated, the condensate produced by these appliances can potentially harm the environment and drainage systems over time due to its low pH (typically 2 to 4). The pH-Treat line-up provides customer options based on cost of ownership, maximum install versatility, range for different system types, and whether there is an available drain nearby.
