Refrigeration contractors are keenly aware of the value of the maintenance they perform for their grocery store and supermarket clients, but, in some cases, they may find themselves working with clients who underestimate it.
CAREL has introduced the HEOS Sistema high-efficiency showcase controller, a technologically advanced, high-efficiency solution for the management of refrigerated cases and cold rooms for the food retail industry.
Danfoss recently hosted its 25th EnVisioneering Symposium, which addressed how an increasing industry-wide focus on refrigerants and energy is driving changes in the design, deployment, and maintenance of refrigeration equipment and supermarkets.
MTL Cool said its new line of display cases using R-441A offers improved efficiency compared to units running on either R-134a or R-290 (propane), with test data showing that the first of this line, the new NRC2 system, runs on a 17 percent lower charge and requires 17 percent less energy compared to units running on R-290.
The global natural refrigerants market is forecast to reach $1.4 billion by 2020, growing at a compound annual growth rate (CAGR) of 11.5 percent between 2015 and 2020, according to a report published by MarketsandMarkets.
With thousands of dollars of perishable product under refrigeration at any given time, restaurant owners and managers prize speed of service above all else from their refrigeration contractors.
Trends in supermarkets can often provide insights into changes to come for the rest of the commercial refrigeration world, and — as is the case industry-wide — refrigerants are on the minds of many in the supermarket sector.
The global market for refrigerated display cases and chilled rooms is forecast to grow at a compound annual growth rate (CAGR) of 10.5 percent from 2014 to 2020, according to a report available from Research and Markets.
