Corrosion Resistant Cooling Towers

Cooling towers rank highly as included components of heat rejection systems. Building and facility HVAC and industrial process cooling commonly rely on cooling towers as the final phase of transferring heat from inside a system, such as a building, to the outdoor environment. With most relying on the evaporation of water as the means to efficiently move large amounts of heat, cooling towers contain large wetted surfaces in almost continuous contact with solutions of water and various chemicals used to maintain certain fluid conditions. The heat transfer solutions can be aggressive, and many towers are constructed using metal for the wetted parts and case of the unit. This has traditionally been an area of concern with cooling tower ownership, since the combined elements of water, treatment chemicals, and time take their inevitable toll on the equipment.

Avoiding the deterioration of metal clad cooling towers is construction utilizing high-density polyethylene (HDPE). HDPE is not impacted by water, treatment chemicals, or elements often present in the air, whether harsh chemical vapors emitted from nearby industrial plants or natural corrosives such as salt air.

Delta Cooling Towers, Inc., based in New Jersey, USA, manufactures HDPE cooling towers and possesses an extensive portfolio of completed successful applications utilizing HDPE construction features. Below is a short case study showing how one industrial user benefited from installing HDPE cooling towers.

Read the case study and get more information from an application specialist. See how incorporating HDPE cooling towers into your operation can reduce maintenance burden and lead to longer machinery life.

In any business venture or other organization, relying on doing things the way they have always been done can be detrimental to real progress and improvement. Incorporating change involves risk, but good planning and careful analysis will increase the probability of success.

Cooling Towers for Exothermic Reactions in Corrosive Atmospheres

Delta Plastic Cooling Tower
The term “exothermic” describes a reaction or process that releases energy, usually in the form of heat. In chemical processing and manufacturing, controlling the heat created by an exothermic reactions is critical to preserve quality, production and safety. A common way to remove heat is the use of a cooling tower.  Cooling water is circulated through the industrial process via pipes or tubes to extract heat, and then passes through a cooling tower to remove the heat so it can then be recirculated back to the process.

Many exothermic reactions occur when mixing harsh compounds or chemicals. These harsh chemicals have a negative impact on the performance of the process equipment handling the reaction. The equipment is also exposed to vapors and contaminants in the surrounding atmosphere. Metallic structures are the most prone to attack and corrosion.

When a cooling tower is needed in a corrosive or harsh environment, metal framed cooling towers with metal walls should be avoided. Instead, cooling towers with seamless, double wall plastic (HDPE) shells, corrosion proof construction, PVC piping and water distribution systems and totally enclosed motors are recommended.

Sample industries where plastic cooling towers are used in harsh environments are water treatment, waste water treatment, pulp and paper processing, primary metals processing, plating, and corrosive chemical production.
