Question 1

Who supplies cooling tower treatment chemicals in Oman and the GCC?

Accepted Answer

Global Chemicals LLC stocks the complete open- and closed-loop programme in Muscat: scale and corrosion inhibitors (Altreat 4000, Cool Water Treat, Corro Guard), oxidising and non-oxidising biocides, antifoulants for seawater-cooled systems, closed-loop chiller inhibitors and biocides, and hardness-control boiler chemicals. We treat district cooling plants, hotel and mall HVAC, and process cooling across Oman and the UAE, with water-analysis-based programme design and residual test kits supplied alongside the chemicals.

Question 2

How is Legionella controlled in cooling towers in the Gulf?

Accepted Answer

Gulf ambient temperatures put tower basins in the ideal Legionella growth band for most of the year, so control has to be continuous, not reactive: maintain an oxidising biocide residual (0.5–1 ppm free halogen) with a weekly alternating non-oxidising biocide shot to prevent resistance, keep cycles of concentration controlled to limit nutrient build-up, and physically clean basins and fill quarterly. Monitoring pairs weekly dip-slide counts with periodic Legionella-specific sampling. We supply both biocide families with a dosing schedule matched to your system volume and blowdown.

Question 3

What causes scale in cooling towers and how is it prevented?

Accepted Answer

Evaporation concentrates the make-up water's calcium and alkalinity until calcium carbonate exceeds solubility — in Oman's climate a tower at 5 cycles concentrates minerals five-fold at the region's highest evaporation rates. Prevention combines cycles-of-concentration control via conductivity-based blowdown with a phosphonate-polymer inhibitor (80–150 ppm of recirculating water) that holds hardness in suspension. The sustainable cycles depend on make-up hardness, silica and the inhibitor programme — send your make-up analysis and we calculate target cycles, blowdown rate and chemical consumption.

Question 4

What treatment does a closed chilled-water loop need?

Accepted Answer

A closed loop needs three things at commissioning and maintained thereafter: a corrosion inhibitor (molybdate or nitrite programme at an initial 2–5% charge for mild steel, with azole for copper), a compatible biocide to stop microbiological growth in the low-flow sections, and — where freeze or heat-transfer specs demand it — inhibited glycol at the engineered concentration. Annual water analysis confirms inhibitor residual and checks for bacterial activity or glycol degradation. We supply the inhibitors, closed-loop biocides, inhibited MEG/PG, and the test kits to monitor all three.
