Water-Cooled vs. Air-Cooled Equipment:

How Should You Stay Cool?

Water-Cooled vs. Air-Cooled Equipment:

When seeking to cool a large scale commercial or industrial facility, insufficient information often leads to an unsatisfactory solution. While some stakeholders choose water-cooled chillers because they believe the cooling tower in these systems offers more efficiency, others prefer air-based cooling systems because of the less prohibitive upfront price. And with recent technological advances made in both air and water-based chilling systems, determining which option is the right fit has become even more challenging. To decide which system best suits a specific project’s needs, it’s important to understand the pros and cons associated with each option.

Deaerator Design and Operation

A deaerator preheats boiler feedwater and removes dissolved gases, especially oxygen and carbon dioxide. These gases are undesirable because they cause corrosion and increase treatment chemical requirements. 

Deaerators operate based on the reduced solubility of dissolved gases as temperature increases. For example, the solubility of oxygen decreases from about five ppm at 150oF to about two ppm at 190oF. Virtually all the free carbon dioxide gas is removed by increasing the temperature to greater than 170oF.
