How we approach it
An evaporative condenser combines the condenser and the cooling tower in 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.

What we can build to
These ranges cover most 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 |
| Water treatment | Bleed, dosing and conductivity control interfaces |
Indicative figures. Final specification is confirmed against your duty and a site survey at quotation.
Standards and testing
- Hot-dip galvanising to ASTM A123
- Thermal performance selected to CTI methodology
- Coil pressure tested before dispatch
How the work runs
The same sequence every time, so you know what happens next and what is expected of you at each stage.
Step 1
Load and site survey
Heat rejection duty, refrigerant or process fluid, available space, and the design wet bulb for the actual site, not a regional average.
Step 2
Selection and layout
Unit selection with airflow clearances checked against the real plant room or roof. Recirculation is the most common cause of underperformance and is designed out here.
Step 3
Supply and installation
Delivery, setting, pipework and electrical connection, including make-up water and bleed lines.
Step 4
Commissioning
Water distribution checked across the full coil face, fan rotation and current verified, and approach temperature recorded against the design figure.
Step 5
Ongoing maintenance
Planned service covering fill and eliminator condition, nozzle clearance, drive belts and bearings, and basin cleaning.

Asked before you ask
Straight answers to the questions we hear most on this service line.
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. If it is genuinely close, we size both.
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 hold those components.
