Run your cooling tower at 6 cycles, not 3. Without rewriting the chemistry SOP.
If your team is part of Engro Fertilizers' Project Catalyst (the cross-site water-treatment vendor substitution programme), or you run utilities at Engro Polymer Port Qasim, Engro Powergen Thar, Qadirpur, or any of the legacy chemicals sites — AAS is a Karachi-based principal-direct chemistry house, sole Pakistan agent for Shaanxi Ande and Innovative Water. Same-week dispatch on PAC, CPAM, UN-307, UN-611, AD-401, AD-303, AD-402.
Programme audit on request · Vendor-substitution friendly · CoA on every drum
Engro Powergen is squeezed on the same OPEX line as KE — chemistry is the lever.
NEPRA's Rs1.42/unit fuel-cost adjustment for April 2026 hit every thermal IPP, including Engro Powergen Thar and Qadirpur. The 16 April KE tariff cut signalled the new regime: every condenser shutdown now hits the P&L twice. Meanwhile Engro Fertilizers' Project Catalyst team is openly substituting site water-treatment chemistries (per public LinkedIn bios from process engineers at Daharki). AAS is the Karachi chemistry desk that walks the BFW skid the same week, with batch CoAs and a stocked SKU list.

Where AAS chemistry has substituted into existing programmes.
Cooling-loop programme replacement · Karachi · 2018
Took over a 12,000 m³/h cooling tower from an incumbent supplier with persistent CaCO₃ scaling. Reformulated to AD-401 + AD-303 programme; cycles of concentration moved 3.2 → 5.1 inside 90 days. Identical pattern to a typical fertilizer-site loop.
Vendor substitution at a refining utilities site · 2022
Replaced incumbent on a beverage-bottling plant's cooling and softening programmes with NSF-grade chemistries. Programme renewed in 2024. Audit-ready documentation passed first-pass buyer compliance.
Closed-loop cooling commissioning · Port Qasim · 2025
Design-build of a 1,800 m³/h closed-loop cooling system. AAS supplied skid fabrication, commissioning, and chemistry retainer. 18 months on retainer to date.
Stocked SKUs, every drum with a CoA.
Sole-agent direct from two specialist Chinese principals (Shaanxi Ande, Innovative Water) — no trader mark-up, single legal entity at the Karachi office and the dosing skid. Per-batch certificate of analysis on every shipment. Engineering desk in Karachi for feedwater audits, programme design, commissioning, autopsy.
PAC — polyaluminium chloride, multiple Al₂O₃ basicities, liquid + powder CPAM — cationic polyacrylamide, multiple charge densities, powder + emulsion UN-307 / UN-611 — RO antiscalant + non-oxidising biocide for membrane systems AD-401 / AD-303 / AD-402 — cooling-tower antiscalant, corrosion inhibitor, recirculating-system fungicide

Capability statement, ready to share with the engineering team.
If your team is preparing the next utilities-chemistry tender, or you have a current scaling / fouling / foaming event that needs a chemist on the dosing skid this week, AAS can come to your site the same business day in Karachi. Capability statement PDF is below; ISO 9001 cert, NSF documentation where applicable, and sample CoAs shared on supplier-qualification request.
I'm with Engro and want to evaluate AAS chemistry against our current programme.
Tell us your site, the loop or train, the symptom, and the volume. Same-business-day reply from Karachi with a programme outline and the relevant CoAs / SDS attached.
