Dry coolers or liquid coolers are used in many applications, like conditioning (HVAC) and industrial processes in general, where there is the need to cool a liquid (typically water or saline solutions).
Compared to open tower or closed circuit tower applications ,the dry cooler has some advantages and some particular disadvantages.
When selecting the adequate type of system, these aspects will be analyzed in detail, so as to be able to propose the best solution.
Advantages (compared to a cooling tower):
- elimination of water consumption (models without sprinklers)
- elimination of water treatment systems (without sprinklers)
- no problem in the formation of legionella (models without sprinklers)
- more controlled noisiness
Disadvantages (compared to a cooling tower):
- need of higher installation surfaces
- higher fluid outlet temperatures
- higher electricity consumption
W-tech range of Dry Coolers are designed to meet the growing market requests in terms of performance, reliability and durability.
Dry coolers are designed to operate with different types of fluids such as, water, liquid solutions (ethyl glycol / propylene), but also with alimentary fluids such as vegetable or synthetic oils or fluids typical of the processing industry.
The "WET" dry cooler is equipped with a water spray system which allows to lower the outlet temperature of the fluid, in particular times of the day, typically the hottest hours or during seasonal peaks.
On request there are multi-circuit versions available, with larger surfaces, special pre-painted fins, of copper or subject to anti-corrosion treatments.
There are available sections with increased heat exchange coils or with stainless-steel structure. The layout of the heat exchange coils, as well as the diameter of the tubes may vary depending on the specific needs of the customer.
