GEA Refrigeration Technologies announced that it has consolidated its United States-based companies into GEA Refrigeration North America Inc., and has created a central sales organization headquartered in York, Pa.
Interest in so-called natural refrigerants continues to grow, especially when it comes to the refrigeration of food. Here are some examples that illustrate how companies are using natural refrigerants to keep food cold and fresh.
EMCOR Group Inc., a leader in mechanical and electrical construction, energy infrastructure, and facilities services, announced that its subsidiary USM Inc. has been awarded a three-year contract for integrated facilities management (IFM) at 742 Ruby Tuesday owned restaurants throughout the United States.
With ongoing refrigeration system problems, and no replacement parts available for its old Beacon systems, the McDonald’s owner in Godfrey, Ill., looked to the ingenuity of its service company, R.E.C. Service Corp., for a solution.
The Air-Conditioning, Heating and Refrigeration Technology Institute (AHRTI) has completed a research project on performance standards for walk-in refrigerator and freezer systems.
One of the basic components selected when installing a walk-in cooler/freezer or any field-assembled refrigeration system is the metering device, typically the thermostatic expansion valve (TXV). The TXV needs to be selected to match the Btu capacity of the system’s evaporator and compressor.
Perlick Corp., a maker of undercounter refrigeration, announced it has extended its residential products warranty to three years. The warranty is applicable to products built after Feb. 1. The warranty covers all parts and labor to repair or replace any part of the product, for three years from the date of the original purchase.
Ammonia is both a friend to refrigeration contractors and a danger, too. When used properly in refrigeration units, its outstanding heat transfer capabilities can keep food cold for long periods of time, it does not harm the environment, and it is biodegradable. But exposure to ammonia does pose a danger to human health.
A well-designed medium temperature refrigeration system will maintain both a proper case temperature and relative humidity (rh). The preservation of food depends not only on the temperature, but also on the relative humidity within a case.
The International Institute of Ammonia Refrigeration will hold its 2012 Industrial Refrigeration Conference & Exhibition, March 17-21 at the Frontier Airlines Center in Milwaukee.
