Hermetic Compressor Offers Improved Efficiency
Emerson Climate Technologies, Inc., a business of Emerson, has released an extension of the RST hermetic compressor line for commercial refrigeration applications. The units extend from 7,000 to 10,000 BTUHs (MT R-404A models). According to sources, the newest compressors provide an improved solution to meeting end-user needs, by delivering enhanced system efficiencies and reliability, for a lower cost of equipment ownership.

The RST has been engineered to address both current and future challenges of foodservice, industrial, and environmental-medical applications. The newest models feature patented technology to improve liquid handling, for improved reliability and performance. The RST also offers high efficiency motors for improved starting, plus noise reduction features ideal for sound sensitive applications.

Blast Chiller/Freezers Adjust Chilling Cycles
Master-Bilt has released the Master-Chill™ MBC model reach-in and undercounter blast chillers/freezers. The MBC series self-contained units are designed to rapidly and uniformly decrease the temperature of hot foods to either a chilled or frozen state. The rapid temperature reduction enhances food safety, increases storage life and improves production efficiency. Master-Bilt’s new MBC Series features the newest patented technology in blast chillers/freezers with the Food Identification Controller (F.I.C.). F.I.C. automatically adjusts blast chilling cycles with its single multi-sensor probe. The F.I.C. monitors temperatures in the core, beneath, and on the surface, to prevent surface freezing and degradation, and preserve the nutritional value of the food. These new models meet all federal HACCP (Hazard Analysis Critical Control Point) requirements for food safety. Through the chilling cycle, food temperature is dropped from 194F to 37F in 90 minutes. In the freezing cycle, the food temperature is reduced from 194F to 0F in four hours.
