The U.S. commercial refrigeration OEM recently unveiled a line of self-contained propane cases for food retail.
St. Louis, Mo.-based OEM Hussmann, a provider of food retail display cases and refrigeration systems, has become a gold partner on hydrocarbons21.com.
In 2013, Hussmann supplied one of the first almost-full-store propane (R290) systems using self-contained cases in the U.S., at an HEB Grocery store in Texas. Recently it launched microDS, a water-cooled micro-distributed system that uses self-contained R290 display cases.
“We have been at the leading edge of this technology,” said Richard Gilles, senior product leader, Hussmann.
The microDS line encompasses low- and medium-temperature merchandisers, including five-door reach-ins and open multi-decks up to 12-ft long.

Hussmann is proud of regularly receiving positive feedback from its customers for complete store installations, said Gilles. “This strong customer focus is a great asset. Innovative solutions for particular needs of customers amplify this strength.”
The firm plans to produce solutions for complete stores of different sizes in several climate conditions.
Hussmann considers climate-friendly hydrocarbon systems as a promising, future-proof growth market, “providing a solution which is not subject to future regulations,” said Gilles. Hydrocarbons, he added, can be used in all aspects of refrigeration and perform well in all conditions.
“Our hope is to see installations continue to grow to further safeguard the environment,” said Gilles.

International IEC standard 60335-2-89 currently limits the use of flammable refrigerants like propane in hermetically sealed commercial refrigeration equipment with an incorporated or remote refrigerant unit or compressor to 150 g.
IEC is close to potentially increasing the charge limit to 500 g next year, which would enable Hussmann to reduce the number of condensing units required per store – thereby reducing energy consumption.
