Natural refrigeration manufacturer M&M Carnot is expanding its headquarters in Federalsburg, Maryland (U.S.) by leasing an existing 25,000ft2 (2,323m2) space next door, with room available for future expansions, according to Maryland’s Department of Commerce.

This is expected to double the company’s workforce from 100 to 200 over the next two years.

“We are proud to support M&M Carnot’s expansion in Federalsburg, where 100 new jobs will have a significant impact on the Eastern Shore community,” said Maryland Governor Larry Hogan. “The company has had great success in growing its staff recently, and we believe this additional space will allow M&M to continue expanding its manufacturing and production, as well as its workforce, in Maryland.”

“We are excited to expand our natural refrigeration business in Federalsburg,” said David Sholtis, CEO of M&M Carnot. “With the hard-working people of Caroline County, we can continue to meet the rapidly growing needs of our customers for natural refrigeration solutions.”

To assist with the expansion, the company is eligible to apply for several state programs and incentives, including More Jobs for Marylanders; Partnership for Workforce Quality; the Job Creation Tax Credit; and others.

CO2 and ammonia

Formed in 1969, M&M Carnot focuses on natural refrigerant-based commercial and industrial systems, including CO2 (R744), low-charge ammonia/NH3 (R717) and ammonia/CO2 cascade. Its systems are used across several industries and are implemented in cold storage, food processing, ice rinks, data center and supermarkets.  Previously known as M&M Refrigeration, the company changed its name after acquiring the Canadian business Carnot Refrigeration in 2019. 

M&M Carnot Refrigeration has published a white paper to help owners of data centers replace high-GWP refrigerants with its Aquilon CO2 system. The M&M Carnot Aquilon CO2 range also includes the plug-and-play transcritical Aquilon Industrial refrigeration rack, the Aquilon Chill and the Aquilon DS, a transcritical CO2 condensing unit.

In September, M&M Carnot received the ATMO Approved natural refrigerants label from ATMOsphere, publisher of The label is a global gold standard highlighting best-in-class manufacturers of natural refrigerant systems and components around the world. 

“We are excited to expand our natural refrigeration business in Federalsburg.”
