Preferred Presents at 2021 ASPE

Lee Carnahan and Len Swihart will present at the 2021 ASPE Tech Symposium

Two members of Preferred’s industry-leading team of product specialists have been selected to present at the 2021 ASPE (American Society of Plumbing Engineers) Tech Symposium, which will be held in San Diego in September. This conference is focused on the plumbing industry, and it will bring together engineers and designers from across the country to network and expand their industry expertise.

Lee Carnahan, who handles sales for our West territory, has been working exclusively with fuel oil-handling systems since 2006, both on the contracting side as well as the manufacturing/sales side. Throughout those 15 years, his top priority has been working with mechanical and plumbing engineers to assist in system design, efficiency, and reliability, as well as specification development. Lee has been a guest speaker at many ASPE Chapters over the years and was a past ASPE Technical Symposium speaker in Orlando. Lee is also trained in OSHA safety and excavation safety, and he is a graduate of the University of California.

Also presenting will be Len Swihart, our California Combustion Manager. Len has been working on combustion systems for more than a year since retiring from the Marine Corps in 2020. Len assists mechanical engineers with design development and specification design for boiler systems, ultra-low NOx burners, burner control systems, and complete boiler combustion systems. Len also helps plumbing engineers with design development and specification design for fuel oil handling systems up and down the West Coast.

The title of Len and Lee’s presentation will be “Fuel Oil-Handling Systems for Generators & Boilers.” They will talk about all aspects of above-ground and underground fuel oil handling systems, covering small systems, such as remote fill systems, all the way up to large mission-critical systems, such as hospitals and data centers. The session will review design development, key questions, time-saving rules of thumb, and different options to achieve the owner’s goals.

Congratulations on being selected to present at this prestigious conference, Len and Lee!
