Cooling towers are complex systems that require careful water treatment not just during regular operation, but also during that critical moment of initial start-up after the off-season. While it may be tempting to rush through start-up to resume cooling as soon as possible, methodical adherence to start-up best practices pays dividends in the long run with improved efficiency, cost savings, and avoidance of major operating issues or even threatening safety situations.
Building owners, property managers, facility engineers, and maintenance teams should partner with knowledgeable professionals for their start-up needs. This article provides an overview of essential steps for a successful cooling tower start-up.
Pre Inspection
An extensive inspection should be the first step before filling the tower basin or re-starting any equipment. Check the entire cooling tower structure as well as connected pipes and heat exchangers for accumulated debris, microbial film, sediment, or signs of damage that may have occurred while off-line. Identify and properly replace any worn parts to minimize the risk of leaks or operational failures down the line.
Filling Tower and Initial Analysis
Once your tower is inspected, the tower should be filled. Before allowing any extended water circulation, your water treatment partner should collect samples to determine current parameters of the water prior to adding any chemical. Initial dosing of chemicals will come next. This prepares a bacteria and algae-free environment resistant to corrosion, scale, and fouling.
Maintain detailed chemical treatment logs noting what gets added, plus readings for parameters like free chlorine and pH which indicate treatment efficacy. Most water treatment controllers will provide basic parameters but further details should be provided on a monthly basis from your service provider.
Continuous Monitoring
Even after a successful cooling tower start-up, ongoing vigilance is vital to efficiency and safety. Work with a qualified water treatment provider for continuous monitoring that goes beyond one-and-done treatment. Their technicians can take regular water samples to proactively test for harmful pathogens like Legionella as well as important chemical parameters.
It is necessary to track corrosion rates, microbiological activity, and scale potential against optimal benchmarks customized for your system. Responsible parties should have 24/7 access to monitoring results through an online portal with automated alerts for out-of-range readings.
This empowers timely adjustments to get parameters back in line well before small issues cascade into bigger problems.
Spring Tower Cleaning
Over months of fall and winter downtime, cooling towers accumulate mineral scale, biofilm, sediments, and other deposits inside even when properly winterized. These gradually impede water flow, heat transfer and equipment longevity if not removed.
A comprehensive spring tower cleaning service helps ensure the water basin, fill, sump, and connected pipes are clear of debris. This helps optimize cooling tower performance for the future by maximizing efficiency, avoiding unplanned summer shutdowns, reducing filter cleanings, and extending system lifespan.
Benefits of Proper Start-Up
A methodical, by-the-book cooling tower start-up sets up the entire operating season for success. Energy savings mount when heat transfer efficiency remains high over months of operation. Water treatment costs decline as well without excessive chemical usage combating contamination or operational problems.
Most importantly, effective start-up safeguards the health and safety of building occupants by preventing conditions that lead to Legionella or other waterborne pathogens. It also helps avoid regulatory violations in jurisdictions with mandatory compliance.
While every facility manager surely recognizes these benefits, the specialized expertise required to achieve them remains less common. Inadequate in-house capabilities or rushing through start-up risks system damage, energy waste, outbreaks of dangerous waterborne illnesses, and violation of codes.
