What DosaFil Residential Technologies does

DosaFil Residential Technologies is the residential-facing sub-brand of DosaFil Limited, a Liverpool, UK-based manufacturer founded in March 2017 by Steve Crick. The company designs and produces solid chemical water treatments for residential heating and plumbing systems, alongside its core commercial and industrial HVAC water conditioning equipment under the DosaFil-Duo device family. Its technical proposition rests on a patent-pending DosaFil-Duo device that uniquely combines chemical dosing, side stream filtration, and air removal in a single integrated unit, paired with a solid paste chemical format (the DR1 inhibitor carries the world's first NSF International CIAS certification for a solid closed-system inhibitor) that delivers a 92% weight reduction versus conventional liquid chemistry and is supported by a magnet-free, online-cleanable design.

The business operates a B2B go-to-market, historically serving commercial and institutional end users such as a Police Authority, a commercial office block, a care home, a secondary school, and Anker Elemental, with a stated base of 'hundreds of clients in just a few years'. Distribution is delivered through channel partners including SolidTek (solid chemicals, 2017), Roth UK (Europe's largest underfloor heating supplier, 2019), and Aquachem DAC (Ireland, 2021), with DosaFil also offering direct sales and equipment hire. Commercial and institutional specification work is supported by a nine-model DosaFil-Duo range spanning a wide temperature, pressure, and flow envelope, the 2021-launched Nano range for smaller systems, and the 2023/2024-launched Residential solid chemical range that extends the chemistry platform into the residential specification channel.

The company is privately held and founder-led, with no disclosed external funding, and has invested in IoT and Industry 4.0 development through a partnership with Liverpool John Moores University. Award recognition includes ASCP Safety and Compliance Awards 2024 shortlisting for Product of the Year and Net Zero Initiative, and a Defence Employer Recognition Scheme Silver Award in 2024.

Core offering

DosaFil Residential Technologies manufactures the DosaFil-Duo, a patent-pending conditioning device that uniquely combines solid or liquid chemical dosing, constant side stream filtration (0.5-50 microns), and continuous air removal for closed loop heating and cooling systems. The portfolio also includes the world's first NSF International CIAS-certified solid chemical range (DR1 inhibitor, DR2 cleaner, DR3 heavy duty cleaner, DR4 biocide) for residential heating systems, plus the CPR-Technology pre-commission cleaning system and a paid water sampling laboratory service.

Product overview

DosaFil Residential Technologies offers two main product lines: commercial HVAC water conditioning devices and residential solid chemical treatments. The commercial portfolio centers on the DosaFil-Duo device family, which combines chemical dosing with side stream filtration and air removal in non-pumped and pumped (PV) versions. The residential line features the world's first solid chemical range (DR1-DR4 inhibitors, cleaners, and biocides) for domestic heating systems. Services include device hire, system health checks, and CPR-Technology for pre-commission cleaning. The company is ISO 9001:2015 certified and an official Grundfos OEM partner.
