In the world of process cooling and freezing, there are diverse operations and needs. As such, selecting equipment appropriate to the application is essential if you are to achieve good results.

Linde started up a new carbon dioxide (CO₂) plant in Freeport, Texas, that will recycle the crude CO₂ supplied from an MEGlobal process. The crude CO₂ will be purified and liquefied into commercial grades to serve customers in a variety of industries, including food and beverage, where it is used to carbonate drinks, as well as to freeze, chill, preserve and package food.

When it came time for one large fishing trawler to replace its on-site refrigerating plant, there were two solutions based on natural refrigerants: an ammonia system or a CO₂ system. Global Seas opted for a CO₂ system from Seattle-based Highland Refrigeration for its 148’ long Northern Defender. 

As the cost of refrigerant has increased during the past several years, detecting and preventing leaks, and reducing refrigerant emissions, have become high priorities for large chilling plants, food processing plants and cold-storage facilities, among others. In order to do this, refrigerant management through effective leak detection and refrigerant tracking is essential.

The objective of all cryogenic tunnel freezers is to quickly freeze or cool products in an efficient manner using a cryogenic liquid.

Industrial refrigeration systems have long taken a standardized approach when it comes to their design and construction. Over time, industrial cooling trended toward no longer being engineered so much as replicated, using decades-old but proven designs. This was the case even for new facilities. Ultimately, the results were that industrial cooling systems were falling behind in terms of available technology.

Engineers, end users, wholesalers, manufacturers and contractors involved in natural refrigeration using ammonia and carbon dioxide will gather, learn and share at the annual IIAR conference in Phoenix on March 3-6.

Line of industrial refrigeration products leverages the company’s experience with CO₂ in the commercial market for industrial use. The new products are intended to support the effort to reduce ammonia in the cold storage space.
