How the OFTWH works

The OneFlow® Anti-Scale System provides protection from scale formation on internal and external plumbing surfaces. The OneFlow® system is a single cartridge-based system that must be installed on a cold water line prior to a waterheating device (water heater or tankless water heater) for single tankless heaters.

OneFlow® prevents scale by transforming dissolved hardness minerals 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 and on fixtures are no longer a concern.

OneFlow® is not a water softener. It does not add chemicals. It is a scale prevention device with proven third party laboratory test data and years of successful commercial, residential and food service applications. OneFlow® is The Intelligent Scale Solution™ and is a great alternative to water softening (ion exchange) or scale sequestering devices.

Features

Chemical-free scale prevention and protection – converts hard-ness minerals to harmless, inactive microscopic crystals making OneFlow® an effective alternative technology to a water softener for the prevention of scale due to water hardness
 

  • Virtually maintenance free – No salt bags or other chemicals to constantly add or maintain
  • No control valve, no electricity and no wastewater
  • Uses environmentally friendly “green” technology
  • Improves efficiency of all water heating devices and downsream plumbing components.
  • Simple sizing & installation – standard 3/4″ connections
  • Perfect system for restaurants, cafeterias, coffee shops and homes where multiple or single equipment protection is desired for longer equipment life and reduced energy  consumption
  • Inlet ball valve for easy isolation shutoff and filter changes

OneFlow® cartridge-based systems are easily maintained; change the cartridge once every two years

Easily installed mounting bracket included w/filter wrench to allow cartridge change-outs when necessary
