Licensed Cooling Tower Services

CTI ATC-105 Thermal Testing
Cooling towers play a crucial role in removing excess heat from a plant’s processes. By lowering the cooling tower outlet temperature, the plant’s thermal performance can improve, leading to increased efficiency and revenue. One of the best ways to optimize cooling tower performance is through a CTI ATC-105 Thermal Performance Test.
With over 30 years of experience, McHale & Associates specializes in thermal performance testing using highly accurate, CTI-compliant equipment. Whether you’re looking for CTI ATC-105 compliance testing for contractual requirements or seeking a detailed performance assessment, we offer tailored testing solutions to meet your specific needs and improve your cooling tower’s efficiency.
CTI ATC-140 Drift Testing
Drift emissions from cooling towers are an often-overlooked source of air pollution, and with growing concerns about health and environmental impact, plants are increasingly focused on drift reduction and drift testing.
Cooling tower drift occurs when small droplets of circulating water are discharged into the air as particulate matter (PM). These particulates can contain harmful chemicals and bacteria, such as Legionella, which pose risks to respiratory health. In addition, drift can lead to water loss, corrosion of nearby equipment, and environmental damage over time.
At McHale & Associates, our highly trained CTI Drift Leads utilize a CTI-compliant Drift Test Kit to deliver precise and reliable results. Whether the test is for contractual obligations, a water loss reduction initiative, environmental air permitting, or LEED drift eliminator certification, we provide accurate testing services to ensure compliance and improve operational efficiency.
CTI STD-201 Thermal Certification Testing
CTI STD-201 is a certification program by the Cooling Tower Institute (CTI) that verifies whether all models within a line of packaged cooling towers meet the published thermal performance ratings. To maintain CTI certification, manufacturers must undergo an initial Certification Test and complete re-certification testing annually.
The CTI STD-201 certification process can be challenging for manufacturers, making it crucial to partner with a reliable and experienced testing company. McHale & Associates specializes in STD-201 certification testing, guiding manufacturers through the entire process, from the initial certification to maintaining a fully CTI Certified line of cooling towers.
CTI ATC-128 Sound Testing
Cooling towers can be a major source of noise pollution, affecting both the surrounding community and potentially causing hearing loss for employees. To address this, McHale & Associates offers a specialized noise testing approach, utilizing CTI ATC-128 and other relevant noise standards. Our targeted testing helps identify the root causes of excessive noise and enables the development of effective physical, administrative, and engineering barriers to reduce the cooling tower’s noise footprint.

Characterization of Elliptical Pitot Tube for Water Flow Measurements
In 2018, CTI switched from simplex pitot tubes to an elliptical style pitot tubes for water flow measurements. This change was made to reduce the impact of change in Reynolds number on the calibration coefficient of the pitot tube.
In addition, the new design incorporated a one-inch (1”) round body to reduce the vibration of the pitot. In this process, the blockage area of the pitot probe was increased.
