Industry-first protection solution for HVAC systems



Two 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.

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. The specialists have borne witness to the widespread failure of traditional treatment approaches:

“The proliferation of water treatment issues is due to many reasons, including the incorrect application of products, lack of maintenance, and the occasional necessitation of lengthy system downtime, all of which means that even the best water treatment programs are repeatedly unsuccessful,” said Steve Crick, co-founder and managing director of DosaFil.

“With DosaFil, we’ve created a product that overcomes common water treatment issues, enabling closed commercial and industrial heating and cooling systems to be cleaned, protected and maintained in a very easy, convenient, and above all safe manner, in combination with advanced chemical treatment technologies. Where DosaFil-Duo is installed, systems will be significantly better protected from the risks of corrosion, scale and fouling.”

Smart monitoring technology automatically notifies users of leaks or when filter bags need changing, with communication options for BMS built-in as standard. Oxygen, which would otherwise accelerate the rate of corrosion, is continuously expelled from recirculating water thanks to the unit’s automatic air vent and integrated coalescing device, while a fully insulated jacket prevents heat loss/gain from treated systems.

Manufactured in Britain to exacting standards, DosaFil-Duo is ultimately a green technology that will optimise energy and water consumption, minimise unplanned maintenance and system downtime, and extend the life of boilers and system components. The device is set to revolutionise a market that has for too long suffered the detrimental effects of corrosion, limescale and fouling in commercial and industrial heating and cooling systems.
