February 16, 2023

Tulsa, Oklahoma – February 16, 2023  — MIRATECH Group, LLC continues its expansion with the acquisition of Powertherm Maxim, a Houston-based provider of industrial reciprocating engine aftertreatment, exhaust, intake and process silencers and accessories.

Powertherm Maxim, established in 1969, brings more than 50 years of experience serving a wide range of markets including Power Generation, Energy Infrastructure, Marine and Industrial applications. The Maxim Silencer brand of industrial engine silencers has a long and storied history spanning over 100 years as an industry leader.

“The addition of Powertherm Maxim is an important and exciting acquisition as it helps us further serve our markets by increasing our capacity, product offerings, and customer reach,” said David Zenthoefer, MIRATECH CEO.

“By integrating the Powertherm Maxim brands into our existing MIRATECH brand portfolio we will have one of the broadest and deepest product baskets in our space. With this addition we will provide an unmatched level of support for our clients and business partners, positioning us well for continued growth.”

MIRATECH acquired Powertherm Maxim from the Nesloney family. Current Powertherm President, Dennis Nesloney, and other members of the management team will stay on to maintain business continuity. Powertherm Maxim will continue to operate out of its Houston, Texas headquarters.

“We are excited to join the MIRATECH family. MIRATECH and Powertherm are well respected in the industry and together we will continue to offer our customers market-leading products and customer service,” said Nesloney.

The acquisition of Powertherm Maxim increases MIRATECH’s fabrication capacity by adding a 100,000 square foot custom fabrication shop in Houston, Texas. This will complement MIRATECH’s existing manufacturing facilities in Tulsa, Oklahoma; Prior Lake, Minnesota; Knoxville, Tennessee; Winnipeg, Canada; and Sinntal, Germany.

The combination of the MIRATECH and Powertherm Maxim brands makes it the leading manufacturer and provider of emissions and silencing solutions within the North American stationary industrial engine market.
