What you can expect from us
A flexible design capability
A full range of extended surfaces is at our disposal. It includes tube in plate and spiral wound options. As a result, we can select the most appropriate for your application.
A full range of configurations
We can address your specific requirements relating to efficiency, noise or plant layout. Fans can be configured for either induced or forced air cooling, and the plot area can be minimised using a ‘V’ cooler arrangement.
Low noise solutions
We use the most up to date fan designs to create noise efficient solutions, which meet the most stringent environmental noise criteria. We will factory test our bespoke designs to confirm compliance with contractual noise levels.
How dry coolers work
A dry cooler uses ambient air to remove heat from a process stream. The applications are many and varied. The heat removed directly at the source from a process is transferred into a liquid such as water or a water/glycol mix. Then, it is pumped to the dry cooler for discharge to the ambient air stream once any usable heat is recovered to other process streams.
Dry coolers are, generally, mounted remotely from the process in an area assigned for secondary cooling equipment. The equipment can use a large area of ground. It is critical that the plot area is kept to a minimum. The heat transfer surface must be efficient.
The cooling uses large volumes of ambient air. The quantity is dependent on the approach temperature required for the cooling of the liquid stream. An approach temperature between the incoming ambient air and the returning cooled liquid stream is key to the efficiency of the whole process.
The fans selected must supply the air required in the most aerodynamically and acoustically efficient manner. For processes where the cooling demand fluctuates with process conditions and ambient temperatures, fan performance can be controlled using frequency or voltage control. That way, we continually trim the performance of the equipment and optimise efficiency.
Where equipment is close to residential locations, noise must be limited. Specifications define acceptable noise limits either individually or for combinations of coolers giving overall sound pressure or sound power limits to be achieved. Numerical models of generated noise are a crucial aspect of the design process.
As a recognised manufacturer of dry coolers, we can help you to get the best equipment for your application.
