Home / Water Treatment & Anti-Algae Dosing
Specialist ServiceChemical dosing for open and closed loop systems to prevent scaling, corrosion and legionella growth. Within our HVAC and chiller plant work, this is the request that usually comes with a deadline attached, so we prioritise it accordingly.
Every price is confirmed in writing after an inspection, before any work begins.
Chemical dosing for open and closed loop systems to prevent scaling, corrosion and legionella growth.
Filtration check, chemical balance and physical cleaning on every visit, with pump, filter and chiller condition recorded. Water that keeps going cloudy despite correct dosing is almost always mechanical — a filter past its life or a pump not turning the volume over. We tell you which it is rather than selling more chemicals. Summer needs a tighter interval than winter, and we will say so.
Screw, scroll and centrifugal chiller servicing, cooling tower descaling, fill-pack cleaning and water treatment for plant rooms and hotels.
Plant work scheduled around occupancy, with readings taken and recorded rather than described. Heat-transfer surfaces, control settings and water quality are checked together, because efficiency loss on this equipment is gradual and invisible until someone measures it. Reports are issued in the format facilities managers and inspectors expect, and we work evenings or shutdown windows where occupants cannot be disrupted.

It depends on the scope and site access. Starting from AED 669. An inspection gets you a fixed number before we start.
Yes, out-of-hours and weekend scheduling is available, particularly for occupied commercial sites.
Yes. We use potable-approved disinfectants, flush thoroughly, and the tank is ready for normal use once refilled. If you have requested lab testing, we advise waiting for the results before drinking.
Typically two to four hours for a residential tank, since it has to be drained, cleaned and refilled. We schedule around your day and can split the work across tanks where a property has more than one.
Every six months is the standard expectation for residential and commercial premises, with documentation retained. Buildings under a facilities contract are often on a stricter schedule.

Tell us the property and we will confirm a fixed written price after an inspection.
Water storage in the UAE sits in tanks exposed to sustained heat, which accelerates biological growth in a way that cooler climates do not. Sediment settles, biofilm establishes on tank walls, and what arrives clean at the building can reach the tap carrying considerably more than it should. Dubai Municipality sets expectations here for good reason.
Most owners never see the inside of their tank, which is precisely why the problem develops unnoticed. The first sign is usually taste, discolouration or an unexplained recurring stomach complaint in the household, at which point the growth has been established for some time.
We inspect before quoting, and the written price we give is the price you pay. No revision once the work has started, and no discovery of additional scope on the day. Where a job falls outside what we do, we say so rather than taking it on.
Every job is documented. Photographs before and after go to your WhatsApp the same day, and certificates are issued where one is needed for inspection. The equipment is proper trade kit — HEPA-filtered extraction, calibrated instruments and cameran inspection — because diagnosis before parts is what keeps a quote honest.
We have worked on Dubai cooling since 2021, across 67 communities and everything from a single split unit in a JVC apartment to chiller plant rooms and commercial kitchen extract systems. That range matters, because it means the person who attends has seen your system type before.
Inspection first, fixed price, honest advice.
