Heat Exchange
Closed-loop heat rejection to ambient — no evaporative loss, no make-up water, no treatment regime.
Part of our Air-Cooled Condensers service line — we supply, install and maintain it, not just sell it.
A dry cooler is a finned coil and a bank of fans: process fluid in, ambient air across, no water involved anywhere. Everything that makes an evaporative system efficient is also what makes it a maintenance liability, and a dry cooler simply does not have those parts.
The cost is approach temperature. A dry cooler cannot take fluid below ambient, so the loop it serves has to be designed around that — which is straightforward for machine cooling or free cooling, and impossible for anything needing a close approach.
They are the obvious answer where water is unavailable, where discharge is restricted, or where a site cannot staff the water treatment an open system needs.
Representative units and components. Configuration, finish and connection sizes are built to the order — these show the range, not a fixed model.
Sizes, materials and duty are confirmed against your drawing and a site survey before quotation — nothing here is a fixed catalogue entry.

Options & accessories
Shell and tube exchangers built to duty — copper, cupro-nickel or stainless bundles in carbon or stainless shells, sized against the process rather than a catalogue rating and pressure tested before despatch.

Air-cooled condensers for sites where water is scarce or treatment is impractical. Coil face and fan selection are sized against Saudi summer ambient, not a temperate design day.

Finned-tube radiators and cooling blocks for engine, generator and process duty. Built to the existing core dimensions so a replacement drops into the frame the old one came out of.
