Cooling water treatment – Increase and maintain efficiency of you industrial HVAC cooling system

blog

Cooling water treatment can be quite a mystery. This treatment type is essential, particularly if companies want to maintain and increase their industrial HVAC cooling system. The old proverb, “out of sight, out of mind” is a common philosophy of numerous industrial building owners. This attitude ascends in part mainly due to the internal part of the equipment and piping infrastructure that cannot be easily inspected or seen.

In addition, there are plenty of less-than-trustworthy water-treatment companies selling infective or costly water-treatment equipment and chemicals, which can discourage engineering and maintenance managers from cultivating an effective water-treatment program. Water treatment is deemed as the best insurance for shielding major investments in a buildings’ cooling and heating infrastructure.

If left untreated, water systems can swiftly cause expensive damage. A successful cooling water treatment program for industrial HVAC and portable water systems is compulsory to maintaining the energy proficiency of equipment, to shield building occupants, and to guard the equipment from corrosion and scale.

The Evolution of the Industry

In the last 15 to 20 years, the water-treatment industry has altered substantially, as many companies have pursued instantaneous profit gains through acquisitions and mergers. Currently, there are more than five major companies that provide water-cooling treatment throughout the entire country. Environmental guidelines have also changed the technology utilized in the cooling water treatment industry.

Most cooling-tower systems utilize molbydates and phosphates versus chromate-based inhibitors that were very popular many years ago in controlling corrosion and scale. The latest outbreaks of Legionella have elevated the level of analysis of water-treatment solutions for HVAC systems, spas, cooling waters, portable-water systems, and other fragments of systems that are prone to the breeding of bacteria.

Starting the Program

A majority of commercial and institutional facilities have recognized that developing a strong relationship with cooling water treatment companies is just as crucial as the treatment itself. Choosing a highly reputable company to help with the treatment of cooling water for the HVAC is essential.

Engineering and maintenance managers should regard the association as a partnership where they can discuss openly and assess new water-treatment technologies in order to decide which one is the best option for their HVAC systems. Some managers view several new water-treatment technologies akin to snake oil. However, through proper partnership, they can avert potential calamities from the newest and greatest ideas.

Once a water-treatment company is chosen, building owners should run a raw water analysis. This is a required step in order to construct a cooling water program that is appropriate for their buildings. By conducting a raw water analysis and governing a system’s operational hours, operating temperature, and load factor, a cooling water treatment specialist can regulate the chemicals, equipment, and monitor the program.

To maintain and increase the cooling system of all the HVAC systems, it is not advisable to base the treatment, according to other buildings in the vicinity, given that local water sources and equipment can differ. Additionally, all buildings’ operational hours are usually different.
