Introduction

The OneFlow Innovative Scale Control System 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
®
need additional chemicals. It is a hard scale prevention device
with proven third party laboratory test data and years of suc-
cessful commercial, residential and foodservice applications.
OneFlow is the intelligent scale solution and is a great alterna-
®
tive to water softening or scale sequestering devices.
OFTWH-R - OFTWH
• OneFlow converts hardness minerals to harmless,
®
inactive microscopic crystals making OneFlow
alternative to water softeners
• Virtually maintenance free - No salt bags or other chemicals
required
• No energy consumption (different compared to other scale
control technologies)
• Contributes to reduce water and electric consumption, no
control valve needed
• Innovative technology with an enhanced respect of the
environment, salt free, without additional chemicals
• Improves efficiency of all water heating devices and down-
stream plumbing components
• Simple sizing & installation – standard 3/4" connections
• Perfect solution for homes where equipment protection
is desired for longer equipment life and reduced energy
consumption
• OneFlow cartridge-based systems are easily maintained;
®
change the TAC cartridge once every two years
• Mounting bracket and wrench for cartridge change-outs
included
* Exceeding maximum flow can reduce effectiveness and void
warranty. Pressure drop at peak flow rate is less than 1 bar at
27°C feed water.
** This system is delivered with 3/4" fittings.

Peak flow rate OFTWH-R up to 23l/min
Peak flow rate OFTWH up to 38l/min
Flow capacity (continuous flow rate):
OFTWH-R up to 15,2Lit/min, 24/7/365 for 2 years for the
OFTWH-R-RM cartridge
OFTWH up to 22,7Lit/min, 24/7/365 for 2 years for the
OFTWH-RM cartridge
Maximum pressure: 90psi / 6.2 bar
Maximum temperature: 38°C
Minimum temperature: 5°C
Weight: OFTWH = 6,2Kg | OFTWH-R = 5,7Kg
Capacity: OFTWH-R-RM and OFTWH-RM cartridges do not
have a grain removal capacity, however, other elements present
in the water will gradually degrade the effectiveness of the car-
tridge. Change the OFTWH-R-RM and OFTWH-RM cartridges
at least once every two years.
A OneFlow Innovative Scale Control system shall be installed on
®
the cold water service line to condition the tap water just prior to
the service line feeding the equipment it is designed to protect.
The system will be sized for maximum or peak flow rate based
on the specification of said equipment. A OneFlow
also be installed to protect multiple pieces of equipment from
the ill-effects of hard water scale provided the aggregate peak
flow rate for each piece of equipment it is protecting has been
considered. The system shall be plumbed with a bypass valve to
allow isolation of filter housing to allow the bypass of untreated
water in the event that service or cartridge replacement be nec-
essary. Bypass is recommended but not required. The installa-
tion area should be suitable in size for the housing to be serviced
without encumbrance. The OneFlow
additional water to backwash, flush, or regenerate once put into
service. The system shall not require any chemical additives and
shall not require electricity for operation.
