Water Treatment Specialists Unite to Create
Industry-First Protection Solution for
HVAC Systems
New DosaFil-Duo® is the only device to combine high performance filtration with air removal
and safe liquid or solid chemical dosing capability
T
wo leading exponents in
industrial and commercial water
treatment have joined forces to
create a ground-breaking product for
the
cleaning,
treatment
and
protection of commercial heating and
cooling systems. The patent pending
DosaFil-Duo® is the only device on
the market to combine the safe
dosing of solid or liquid chemical
treatments (of any brand) into hot or
cold closed recirculating water
systems with constant side stream
filtration and continuous air removal.
Uniquely, the unit features smart
monitoring technology as standard to
ensure optimal filter bag replacement.
DosaFil-Duo’s standard operating
20
pressure and temperature ranges are
also unmatched in the market today.
Now field trialed for over 12 months,
this proven technology effectively
protects commercial and industrial
systems from the damaging effects
of corrosion, limescale and fouling,
thereby optimising the energy
efficiency, performance and longevity
of equipment.
Steve Crick and Peter Robinson
developed DosaFil-Duo in response to
key concerns regarding water treatment
and control in the commercial and
industrial HVAC market. The duo has
spent more than 40 combined years in
the water treatment industry within
specialist roles such as industrial water
filtration, manufacture and application of
specialist solid chemical technologies,
and
general
water
treatment
management. Working for companies
like Houseman, Nalco, ApTech Group,
Inc.,
SolidTek
and
Hydro-Gen
Engineering, the specialists have borne
witness to the widespread failure of
traditional treatment approaches:
“It is widely accepted across the industry
that around half, if not more, of all
commercial closed recirculating water
systems
demonstrate
significant
problems due to ineffective or insufficient
water treatment practices, and this figure
certainly tallies with our experience. The
proliferation of water treatment issues is
due to many reasons, including the
