A Strategic Alliance With Air Hygiene
McHale’s Environmental Services, delivered in alliance with Air Hygiene Inc. (AHI), provides stack and CEMS emissions testing designed to meet each client’s particular needs. This alliance combines AHI’s industry-leading stack testing services with McHale’s world-class power plant performance testing services, giving clients one seamless emissions and performance testing solution.
Why Pair Emissions Testing With Performance Testing
Emissions compliance and plant performance are closely linked — combustion efficiency affects both. By pairing Air Hygiene’s stack and CEMS testing with McHale’s power plant performance testing, clients get a single, coordinated view of how their plant is running and whether it meets environmental requirements, rather than reconciling two separate vendor reports.
We look forward to demonstrating how our new alliance will benefit you and your project. We value your continued trust in AHI and McHale to be your solution provider.

Air Hygiene
With our partner, Air Hygiene, we offer emission measurement solutions to various industries. Sources tested include pulp & paper mills, IC engines, and generators, boilers, turbines, thermal oxidizers, BIF sources, incinerators, and refineries.
Their expert site teams can take samples to analyzers and either send them to an accredited laboratory or directly provide on-site analysis for many different constituents.
