Description
OneFlow® Innovative Scale Control Systems - OFTWH-R and OFTWH Series - provides protection from hard scale formation on internal plumbing surfaces. The OneFlow® system is a single cartridge-based system that must be installed on a cold water line prior to a single water heating device (water heater or tankless water heater) that requires protection from the ill effects of hard water.

OneFlow® uses template assisted crystallization (T.A.C.) to attract hardness minerals and convert them into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and are passed to drain. The system requires very little maintenance, no backwashing, no salt and no electricity. Typical hardness problems, especially build-up of scale in heating elements, pipes, water heaters, boilers are no longer a concern. OneFlow® is not a water softener. It does not need additional chemicals. It is a hard scale prevention device with proven third party laboratory test data and years of successful commercial, residential and foodservice applications. OneFlow® is the intelligent scale solution and is a great alternative to water softening or scale sequestering devices.
