Beverage-Air, an Ali Group Company, has launched its first R290 refrigerators to use variable-speed compressors at the NAFEM Show last week.
The brand, based in North Carolina, said the single-door refrigerators are the first in the foodservice industry to feature variable-speed compressors.
Beverage-Air saw a lot of interest in the variable-speed units at the NAFEM Show and plans to increase its product offering with variable-speed technology as a result.
In an interview with Hydrocarbons21.com, Nick Schriner, director of engineering for Beverage-Air and Ali’s Victory brand, said: “Beverage-Air and Victory are 100% committed to transferring to R290. About 80% of what the companies manufacture now use R290, the exception being smaller products that are in the process of being converted.”
The variable-speed refrigerators, called the Cross-Temp Series, include a dual-zone model which were on display at the NAFEM Show, with two separate food-storage compartments and two condensing units. Another model uses one condensing unit for one chamber. Temperatures for both can range from -15°F to 40°F.
Schriner further told Hydrocarbons21: “The variable-speed units employ a ‘drop-in solution’ that includes a smart compressor that can sense the load by how long it takes to achieve a set point, It then decides how much lower rpm it can step down to.”
This technology enables efficiency gains of 30%-35% compared to standard units, which meet the latest Energy Star efficiency standards for commercial refrigerators.
Mayank Patel, refrigeration engineer for Beverage-Air and Victory explained that the extra capacity means that a refrigerator that formerly used two R134a condensing units would need only one R290 unit.
With its commitment to R290, Beverage-Air will not offer condensing units with HFO blends.
Schriner said: “We want to build our units and leave them alone. If we go with [HFO blends], we’ll be there again in five or six or seven years. That’s not where we want to be.”
