When the Environmental Protection Agency (EPA) announced they were going to phase out hydrofluorocarbon (HFC) refrigerants in 2015, many in the industry began preparing for the coming changes. The new proposed regulations under Section 612 of the Clean Air Act, known as SNAP Rule 20, established a schedule to phase out common HFC refrigerants such as R-22, R-124 and R-507.
However, when major chemical companies challenged the EPA in federal court in 2017, a judge ruled the EPA didn’t have the authority to mandate the changes. Attempts to appeal the court’s decision failed, and the EPA acknowledged they will not enforce the rule.
However, just because the rule was overturned at the federal level doesn’t mean you’re in the clear if you use these refrigerants.

Condensers are one of the most critical elements of a refrigeration system. While optimizing the performance of your condenser is important for reducing energy usage and maintenance costs, if you’re building a new facility, it all starts with selecting the best option for your needs.
When choosing a condenser, it’s important to consider where the facility is located. In colder climates, ice buildup and water freezing may occur with evaporative condensers. To work around this issue, you have two options:

What is packaged refrigeration?
Low-charge packaged refrigeration systems are “packaged” or “modular.” The refrigeration equipment is built off site, mounted on a structural steel base (skid), and then delivered to your plant as a self-contained, “plug-and-play” system.
Not only is low-charge packaged refrigeration equipment safer, it also comes with advantages in terms of:
- Field labor savings
- Schedule savings

Low-charge packaged refrigeration is a safe, innovative solution that uses CO2 or ammonia and a secondary refrigerant, such as glycol. This allows facilities to reap the benefits of ammonia’s excellent thermodynamic properties while minimizing the refrigerant charge and risk because the ammonia is isolated to one area and only the secondary refrigerant is circulated throughout the facility.
The system is “packaged” or “modular,” with refrigeration equipment built off-site, mounted on a structural steel base, and then delivered to a plant as a self-contained, “plug-and-play” system.
One of the major advantages of a packaged refrigeration system is ease of installation. Here are some of the main reasons why:

I had the opportunity to attend the 2018 IIAR Natural Refrigeration Conference & Expo in March, and it got me thinking about the value in these industry events. Why do we attend them?
There are countless niche conferences that cover every segment of the food and beverage industry, from packaging to refrigeration and from dairy to meat. These events bring professionals together from across the country and world — but why are they so important?

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.

There has been a push to take advantage of the benefits of ammonia while reducing the risks—and it has resulted in an innovative solution: low-charge packaged refrigeration systems that use ammonia and a secondary refrigerant (such as glycol). This allows facilities to reap the benefits of ammonia’s excellent thermodynamic properties while minimizing the charge and risk.

CO2/NH3 cascade systems offer food processors a practical way to increase efficiency. By using two centralized refrigeration systems working in unison to provide cooling temperatures, they maximize the effect of carbon dioxide and ammonia. The high-temperature system pulls heat away from the low-temperature system, which in turn uses recirculated liquid to cool the evaporators.
Cascade systems that use CO2 as a secondary refrigerant offer unique advantages. Carbon dioxide is nontoxic and nonflammable, and is also less likely to damage food products in the event of a release. For food plant owners, CO2/NH3 cascade systems offer six key benefits, which are detailed below.

For the past two weeks, we’ve discussed packaged refrigeration equipment: a system that uses ammonia or CO2 and a secondary refrigerant, allowing facilities to reap the benefits of ammonia while also minimizing the charge and risk. We’ve already reviewed the various ways these systems can benefit food processors and discussed the five different types of these low-charge chillers available. However, if you decide to introduce packaged refrigeration equipment into your food manufacturing plant, there are some key questions you must answer before installation to ensure an efficient, smooth installation process.
