Down-to-earth technical talks and the challenges of space exploration comprised some of the presentations at the recent International Institute of Ammonia Refrigeration (IIAR) Conference and Trade Show.
The people who operate and service ammonia refrigeration systems are key to the systems' successful operation. But what is there to guide the trainers, to make sure what they are providing is what operators and technicians need?
In a move to call attention to its concern for fair treatment of union workers at Omni Duct Systems, the Sheet Metal Workers' International Association (SMWIA) recently sent a letter to Omni Duct's contractor customers to encourage a boycott.
York International Corp. and The Stellar Group have renewed a business alliance for turbine inlet air chilling (TIAC) projects in the Americas, and expanded their relationship to include Europe and the Middle East.
With system efficiencies continually improving and environmental requirements becoming more stringent, subcooling and superheat measurements have become more and more important. Because of this, one of the most critical measurements - and the one most often taken inaccurately - is that of pipe temperature.
A crankcase pressure regulator (CPR) is a common accessory added to many low-temperature refrigeration applications, such as walk-in and reach-in freezers. The selection of a CPR is based on five system considerations.
Want to know what it takes to be selected to install, start up, and service ammonia refrigeration systems in cold storage warehouses and food plants? Some answers were provided at the most recent International Institute of Ammonia Refrigeration (IIAR) Conference and Trade Show.
Superheat is probably the most talked about, yet misunderstood, technical term used by technicians. Superheat on the system's low side can be divided into two types: evaporator superheat and total (or compressor) superheat.
