Cooling Tower Cleaning

Cooling towers play a crucial role in many facilities air conditioning and industrial process systems but they must be properly maintained and regularly cleaned in order to operate properly. Our full scale method of cooling tower cleaning removes all scale, sediment and organic nutrients, which can lead to bacterial growth and potentially serious health issues.

Why it’s cleaned

Cooling towers are an efficient and cost effective way to cool water for air conditioning and industrial processes. They use a fan to move air through a recirculating water system in an outdoor location. This process along with the exposure to the outdoor elements can lead to the build-up of scale, sediment and biological contaminants. In turn, this build-up can result in system degradation, loss of efficiency and potentially serious health issues. Regular maintenance of the tower and chemical treatment of the systems water supply can help to reduce these issues but a full system cleaning is required to remove all of the contaminant build-up and ensure that all of the tower’s components are operating efficiently.

Should You Have Your Cooling Tower Cleaned?

Per OSHA, cooling towers should be drained and fully cleaned quarterly or at least twice a year. If a cooling tower is not used year round it should be cleaned before initial start-up at the beginning of the cooling season and after shut-down in the fall. Towers that show high levels of biological growth should be cleaned immediately and towers that have been out of service for long periods of time should be cleaned before they are put back in service. OSHA also recommends that new systems be cleaned and disinfected to remove construction residue, which can contribute to biological growth. Guardian performs free, photo documented, inspections for all customers and has certified air system cleaning specialists on staff to help you determine if you or your cooling tower can benefit from cleaning.

Our Cleaning Process

Guardian performs a full scale cleaning of the cooling tower, which involves fully draining the system and cleaning the interior and exterior surfaces by manual and hydraulic means. This includes the cooling tower structure, casing, fans, pumps, piping, spray nozzles, fill, louvers and any other surfaces that show contaminant build-up.

Guardian’s cleaning process begins with a full system inspection to determine the specifics of the cooling tower , identify any issues or damaged areas and formulate an effective cleaning plan. Our technicians access the system in a safe and professional manner and protect all vulnerable components before starting the cleaning process. Once the system is drained, all sediment and debris is removed from the tower basin and collected for safe, off-site disposal. A non-hazardous chemical is used to treat all contaminated surfaces and the interior and exterior of the tower is scrubbed and power washed to remove all contaminants. Once the tower is entirely clean, it is re-inspected for any issues or damage and all components are returned to those settings recorded just prior to the cleaning operations.

Approach and Project Management

Guardian’s cleaning process begins with a system assessment to determine the best cleaning methods to use in order to protect the building occupants and equipment. Protective plastic sheeting is used to cover all vulnerable surfaces. All access points are re-sealed, per code, the system’s performance is checked and our technicians remove all the protective covers. Photo documentation is provided for all projects to document the before and after condition of the system and ensure all areas are properly serviced. Additional cleanliness testing can be performed where required. All Guardian customers will be given access to our customer portal system. The portal is open 24/7 for customers to access their documentation, scheduling, and photos.
