OneFlow®+ Salt-Free Scale Prevention and Water Filtration

Item No: Model OFPSYS



The OneFlow®+ system is an economical and environmentally
friendly physical water treatment technology that helps protect
pipes, extend the life of appliances, and provide better tasting
water through filtration. The OneFlow®+ system is a dual
cartridgebased system with a radial flow 20 micron carbon
block cartridge which reduces sediment, chlorine taste and
odor, and an integrated OneFlow®+ scale prevention cartridge.

The OneFlow®+ system uses template assisted crystallization
(TAC) 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 and on fixtures, are reduced**.

The OneFlow®+ system 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 foodservice applications. OneFlow®+ is the
intelligent scale solution and is a great salt-free alternative to
water softening (ion exchange) or scale sequestering devices.

• Reduces sediment, chlorine taste and odor
• Chemical-free scale prevention and protection - converts
hardness minerals to harmless, inactive microscopic crystals
making OneFlow®+ an effective salt-free alternative to ion
exchange water softeners
• Virtually maintenance free - no salt bags or other chemicals
to constantly add or maintain
• No control valve, no electricity and no wastewater
• Improves efficiency of all water heating devices and
downstream plumbing components
• Simple installation – standard 1" connections
• Excellent system for homes where equipment protection
is desired for longer equipment life and reduced energy
• OneFlow®+ cartridge-based systems are easily maintained.
• Easily installed mounting bracket and multi-function tool
included to allow cartridge change-outs when necessary

A OneFlow®+ scale prevention system shall be installed on the cold water service
line to condition the tap water just prior to the service line feeding the residential
home. The OneFlow®+ system uses a 20 micron radial flow carbon block cartridge
with a dirt holding capacity up to 2.2 lbs (1 kg). This carbon block reduces chlorine
taste and odors for up to 50,000 gallons (189,000 liters) of use, with a flow rate of
3 gpm (11.34 lpm). The OneFlow®+ system also uses a scale prevention cartridge
which is good for up to 250,000 gallons (945,000 liters) or replacement every
3 years, whichever comes first. The installation area should be suitable in size
for the housing to be serviced without encumbrance and the system should be
installed per the Installation, Operation & Maintenance manual as provided with
each system.

The OneFlow®+ system must not require additional wastewater to backwash, flush,
or regenerate once put into service. The system shall not require any chemical
additives and shall not require electricity for operation.
