The first Seattle-area treatment took place at the Museum of Flight, the world’s largest independent, nonprofit air and space museum, which houses more than 150 aircraft and spacecraft on its 23-acre campus.

Treatments were recently completed on several HVAC units within the museum’s Aviation Pavilion, and PSR Mechanical is scheduled to treat additional systems totaling 282 tons throughout the rest of the campus within the coming months. Among the treated units is the system that cools the first Air Force One jet, which was used by several presidents.

ThermaClear is a one-time treatment that eliminates internal oil fouling, a common but often overlooked cause of declining HVAC performance. The treatment works by displacing oil buildup on heat exchanger coils, restoring maximum energy efficiency, and allowing optimal heat transfer, the press release said. It also super-lubricates compressors, reducing wear and tear and lowering the risk of failures. By forming a permanent protective barrier inside the system, ThermaClear prevents future oil fouling and the efficiency losses that come with it, the press release said.

The introduction of ThermaClear in Seattle comes from a national partnership between ECM Technologies and Service Logic, the largest privately held commercial HVAC service provider in the U. S. As a Service Logic company, PSR Mechanical is now one of a limited number of North American providers in the ThermaClear Preferred Service Network. This designation allows PSR to offer ThermaClear as part of its ongoing commitment to building performance and reliability.

“Adding ThermaClear to our service and project offerings allows us to combine our deep expertise in preventive and predictive HVAC maintenance with a cutting-edge technology that restores lost efficiency and protects systems long term,” said Greg Hagen, vice president of PSR Mechanical.
