Water Treatment 

Effective water treatment is crucial and can be cost-efficient. For closed-loop systems without leaks, semi-annual or annual checks are usually sufficient if meters are installed in quick-fill piping. To manage maintenance costs:

​

  •  Increase Cycles of Concentration: Raise cycles from 2 to 6 to cut make-up water and blowdown by 20% to 50%. 

  • Sewer Rebates: Obtain a rebate for evaporated water by installing meters in make-up and blowdown lines

  • Thorough Cleaning: Clean the entire cooling tower, not just the sump, to ensure optimal performance. 

  • Daily Checks: Monitor float and water levels every 24 hours. 

  • Condenser Maintenance: Regularly remove scale from condenser tubes. 

  • Pressure Drop Monitoring: Track and reset pressure drops across condenser tubes as needed. 

  • Vendor Coordination: Ensure water treatment and chiller maintenance vendors work together effectively. 

  • Metal Monitoring: Track mild steel, copper, or other metals in the system. 

Coil Cleaning & Air Filters

One of the most cost-effective investments is regularly cleaning mechanical systems and changing air filters. Clogged filters can impact coils, degrade air quality, and lead to expensive replacements. At Cajun Innovative Solutions, we specialize in cleaning coils that would otherwise need replacement. 

​

Our process begins by measuring the pressure drop across the coil, comparing it to the design pressure drop, and planning the best approach to unclog it. We also partner with companies to balance hydronic and air systems, optimizing your building's air and water systems. 

​

Recent staff shortages have led to deferred maintenance tasks such as changing air filters, placing biocide drain tablets, and cleaning coils. Cajun Innovative Solutions can fill this gap, performing routine air filter changes and other essential tasks to prevent issues like coil replacement, damaged compressors, excessive energy usage, clogged drains, nuisance tripping, fires, and poor indoor air quality. 

Cleaning Cooling Towers

High condenser water temperatures are referred to “chiller killers” because chillers are unable to dissipate heat into the condenser water causing chillers to operate outside designed parameters. While the life expectancy of a water cooled chiller is considered by American Society of Heating Refrigeration Air Condition Engineers (ASHRAE) to be 23 years, this lifecycle is reduced with high condenser water temperatures.

The major failure of high condenser water temperatures are inefficient cooling towers. Cooling towers that are clogged with scale and dirt are unable to remove heat from the chillers and should be cleaned twice per year by taking them offline, pressure washing the fill and drift eliminators, cleaning distributor nozzles and cleaning condenser water strainers.

When cooling towers are cleaned it is imperative that your water treatment service provider is present and fully engaged to ensure her treatment program is effective or than requisite changes are made accordingly.

Additionally, the make up valve feeding the cooling tower must be adjusted to eliminate overflow but able to make up water lost to evaporation and blowdown.

Sewerage and Water Board and other water providers provide customer with a sewer rebate to offset for water evaporated and not sent to the drain.
