Overview
How we approach it.
An evaporative condenser rejects heat by combining the condenser and the cooling tower into one unit. Refrigerant or process fluid stays inside a closed coil while water is sprayed over it and air is drawn through, so the working fluid never contacts the atmosphere.
That closed circuit is the point. It keeps the process fluid clean, removes the fouling and treatment burden of an open tower, and typically rejects the same load in a smaller footprint than a separate condenser and tower pair.
In Saudi conditions, water is the constraint that matters. We size for the real ambient wet-bulb rather than a nominal figure, because a tower selected against an optimistic wet bulb underperforms exactly when the plant needs it most.

On the job
The work, as it runs.
Plant we have installed and equipment we have had apart — photographed on the shop floor and on site, not staged.
Capability
What we can build to.
Ranges below cover the majority of what we make. Duties outside them are reviewed case by case rather than refused on principle.
| Configuration | Induced draught, counterflow and crossflow |
|---|---|
| Coil material | Hot-dip galvanised steel or stainless 304/316 |
| Casing | Hot-dip galvanised steel, optional stainless or FRP |
| Design wet bulb | Selected against site conditionsNot a nominal figure |
| Fan drive | Belt or direct gear drive, optional VFD control |
| Water treatment | Bleed, dosing and conductivity control interfaces |
Indicative figures. Final specification is confirmed against your duty and site survey at quotation.
Standards & testing
- Hot-dip galvanising to ASTM A123
- Thermal performance selected to CTI methodology
- Coil pressure tested before dispatch
Process
How the work runs.
The same sequence every time, so you know what happens next and what is expected of you at each stage.
- 01
Load & site survey
Heat rejection duty, refrigerant or process fluid, available space, and the design wet bulb for the actual site — not a regional average.
- 02
Selection & layout
Unit selection with the airflow clearances checked against the real plant room or roof layout. Recirculation is the most common cause of underperformance and is designed out here.
- 03
Supply & installation
Delivery, setting, pipework and electrical connection, including make-up water and bleed lines.
- 04
Commissioning
Water distribution checked across the full coil face, fan rotation and current verified, and approach temperature recorded against the design figure.
- 05
Ongoing maintenance
Planned service covering fill and eliminator condition, nozzle clearance, drive belts and bearings, and basin cleaning.

Questions
Asked before you ask.
Evaporative condenser or a separate condenser and cooling tower?
An evaporative condenser is usually smaller, uses less pump energy and keeps the process fluid closed. A separate tower makes more sense where you already have a central condenser water circuit serving several loads. We will size both if it is genuinely a close call.
How much water does it use?
Consumption is driven by evaporation, drift and bleed. A closed circuit avoids the process-side losses of an open system, and correct drift eliminators keep carry-over minimal. Actual figures depend on load, water quality and cycles of concentration.
Can you upgrade an existing tower rather than replace it?
Often, yes. Fill media, drift eliminators, nozzles and drives are all replaceable, and a fill and eliminator change alone can recover a surprising amount of lost capacity. We stock those components — see the cooling tower catalogue.
