More changes are coming to the food and beverage industry as the U.S. Environmental Protection Agency (EPA) continues to crack down on ammonia safety.
The EPA has launched a three-year, nationwide enforcement and compliance initiative focused on reducing the risks of chemical releases from facilities that use extremely hazardous chemicals, including those that use ammonia as a refrigerant.

After months of discussions and hours of negotiations, nearly 200 nations have now reached a deal to limit the use of greenhouse gases worldwide. In October, world leaders agreed to the deal that would gradually phase out the use of hydrofluorocarbons (HFCs) starting in 2019.

One of Florida’s oldest third-party logistics companies is introducing one of refrigeration’s newest innovations into its new cold storage facility: low-charge packaged refrigeration systems. With a focus on moving to eco-friendly refrigerants, McDonald’s franchisee Caspers Cold Storage and Distribution will be cooling its new warehouse with an ammonia/ CO2 and low-charge ammonia DX system. Because Stellar will be designing and building the new systems, Accelerate America editor Andrew Williams interviewed Stellar’s Brandon France to learn more about the project. Check out the feature article, “I’ll have CO2 and ammonia with that” in this week’s blog post to learn more about how the company is using low-charge refrigeration systems to lower costs, reduce installation time and utilize green refrigerants.

Lately, we’ve focused on refrigeration compressor packages, blogging about everything from mistakes you may be making with your daily logs to which factors you need to check regularly. This week, we provide an infographic to help you identify red flags that may signal compressor health issues.
The importance of a skilled refrigeration analyst
Aug 6, 2015
After working with compressors for nearly three decades, there’s one mistake I see people making time and time again when it comes to their compressor maintenance. They keep their daily logs, recording necessary temperatures regularly, but when they’re through, they simply put the logs aside and don’t look at them again. The results are not analyzed for corrective measures, if discovered. Are you looking back to ensure you’re addressing the inconsistencies and issues you notice during your compressor evaluations? Analyzing the daily logs is just as important as writing it down.

While we’ve already blogged about ways to determine the fitness of your refrigeration compressor, it’s important to pay attention to the big picture as well. Ensure you keep up with the the health of your entire refrigeration compressor package, as failure to check components including the motor, control panel and suction superheat, can cause major failures. Here are the 14 key factors to check within each component of your compressor package.

Due to its phaseout, an alphabet soup of replacement refrigerants has been developed to replace R-22 in existing chillers. However, most of these alternatives have drawbacks. Some replacements severely penalize the performance of the chiller, while others have significant glide—and all have higher global warming potential than ammonia. And though these refrigerants may not be on the Environmental Protection Agency’s (EPA) phaseout list yet, they have the potential to be. As new chillers rise to replace the old, ammonia is one refrigerant that has become an effective alternative.

The majority of industrial refrigeration systems in the U.S. are central-station ammonia systems—the backbone of the food and beverage industry. For over 100 years, these ammonia systems have dominated the industry because they not only have superior thermos-physical properties, but also because they’re environmentally friendly. Ammonia has a global warming potential (GWP) and ozone depletion potential (ODP) of zero.

Did you know CO2 has been used in mechanical systems since the 1800s? However, over time, the industry has gravitated away from CO2 toward lower pressure, synthetic refrigerants like Freon. But now that synthetic refrigerants are being phased out due to their negative environmental impacts, it’s time to take a renewed look at CO2 as a viable refrigerant alternative.

Refrigeration screw compressors use axial thrust load bearings—and they have a life expectancy that will begin to fail over time. At one time or another, all food processors and beverage manufacturers will be in the market for a refrigeration compressor rebuild or replacement. Because the compressor and its bearings will deteriorate over time, staying on top of its performance is crucial to avoiding a catastrophic failure. Here are three methods that can help gauge your compressor’s fitness.
