Water treatment programmes — chemicals, dosing & testing

Scale and corrosion inhibitors, biocides and dosing systems for cooling towers, boilers and closed loops — matched to your system after a free site survey.

THE SHORT VERSION

We supply the chemicals that keep cooling towers, boilers and closed loops free of scale, corrosion and bacteria. You can order any product from our industrial range by name — and because the right chemistry depends on your water, your metals and how your system runs, every programme starts with a free site survey. A programme is chemicals plus dosing plus testing plus dated reports, delivered as one service.

Why we match the chemistry to the system

Two buildings on the same street can need different chemistry. What is right for your system depends on your make-up water, the metals in your pipework and heat exchangers, your operating temperatures and your operating pH. Even a good biocide performs differently as pH moves — see effects of pH on various biocides.

A chemical chosen without that information can waste money at best and damage equipment at worst. So we look first, then propose. The site visit and the written quotation are free, and the quotation sets out what we would dose, how, and what you would receive.

What a programme includes

  1. Free site survey and water analysis. We inspect the system and test the water before we recommend anything.
  2. Chemical selection. Scale and corrosion inhibitors and a biocide programme chosen for your water, metals and operating conditions.
  3. Dosing. Chemicals are dosed by equipment we set up and maintain — not tipped in by hand.
  4. Routine testing and service visits. Our technicians test, adjust the programme and top up chemicals on a schedule.
  5. Dated reports. Every visit produces a dated report you can file — useful for audits, and for cooling towers the EMSD Code of Practice expects records to be kept for two years.

What we cover

Looking for the products themselves? Browse the Gotech industrial range — 26 corrosion inhibitors, biocides, cleaners and grease-line treatments, with datasheets on request — on the industrial chemicals page.

Looking for chlorine tablets or liquid chlorine for a pool? Those are simpler to buy — packs, drums and a dosing calculator are on the pool chemicals page.

Price and how to start

Programmes are priced to the system, so prices are quoted on enquiry — we reply within one working day. The first step is a free site visit. You receive a written quotation you can keep for your records or attach to a tender, with no obligation.

Frequently asked questions

Can I buy cooling tower water treatment chemicals in Hong Kong?

Yes. You can order any product from Gotech's industrial range by name — we reply with a quotation within one working day. The right chemistry still depends on your make-up water, the metals in your pipework and heat exchangers, your operating temperatures and your operating pH, so if you are not sure, start with a free site survey and water analysis: the written quotation sets out what we would dose, how, and what you would receive.

What does a water treatment programme include?

Five things, delivered as one service: a free site survey and water analysis, chemical selection matched to your water and metals, dosing by equipment we set up and maintain, routine testing and service visits by our technicians, and a dated report after every visit — records the EMSD Code of Practice expects cooling tower operators to keep for two years.
