Product Details

Watts 3631838

This 26'' tall blue OneFlow anti-scale system conditions cold tap water and provides scale protection on internal and external surfaces to extend the life of equipment by transforming dissolved hardness minerals into harmless, inactive microscopic particles. Used for commercial and food service applications, the specially designed components are installed before a water using device (water heater, hot-beverage system, appliance, steamer, etc.) to protect against the effects of hard water. The OneFlow anti-scale system is not a water softener and does not add chemicals or remove minerals, but provides environmentally friendly technology to prevent scale buildup. The 4 GPM system, model OFTWH-R, consists of a single cartridge with a 3/4'' FNPT connection and media which should be replaced every 12 months.
