Home / Water Treatment & Anti-Algae Dosing / DIFC
Water Treatment & Anti-Algae Dosing · DIFCHILLS AC Services provides water treatment & anti-algae dosing across DIFC, Dubai's financial district, made up of premium office towers and corporate headquarters. 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.
Screw, scroll and centrifugal chiller servicing, cooling tower descaling, fill-pack cleaning and water treatment for plant rooms and hotels.
Air handling unit overhaul covering belts, bearings, blower balancing, filter racks and fresh-air intake maintenance.
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.
We schedule jobs in DIFC and the surrounding Dubai area within 24 to 48 hours of booking, with same-day service often available — confirm your slot on WhatsApp.

How we work, what the kit is and what the documentation looks like is set out in full on the Water Treatment and Anti Algae Dosing page.

DIFC is a new installation or a corporate maintenance contract, our team covers DIFC with the same fixed pricing and inspection we offer across Dubai. That is the starting point for how we scope and price work here.
This is commercial stock: offices, retail and hospitality where the system runs to an occupancy schedule rather than a family’s. That means plant sized for peak headcount, fresh-air rates that have to satisfy Dubai Municipality rather than just feel comfortable, and work scheduled around trading hours with a permit and a night slot.
Commercial water systems carry a documented obligation: cleaning, disinfection and laboratory testing on a cycle, with certificates an inspector can ask for. For a building operator the useful output of the visit is the certificate and the lab result, not the clean itself.
None of that is guesswork on the day. We survey the property in DIFC first, tell you what we actually found, and fix the price in writing before any work starts.
Tell us about the property in Difc and we confirm a fixed written price after inspection. No charge to quote.
