In previous blog posts, we’ve discussed that owners of hydrofluorocarbons (HFC) refrigeration systems have some decisions to make as R22 refrigerant is phased out and states take on regulations and enforcement.
Natural refrigerants, like CO2 or ammonia, are good alternatives, but they can sometimes get a bad rap. We’ve debunked some myths about CO2 before — now let’s look at ammonia.

It’s always a good time to check up on your facility’s safety — but now the stakes are even higher when it comes to safety violations.
Employers across the U.S. have been facing higher penalties from the Occupational Safety and Health Administration (OSHA) this year. In January 2019, the federal agency announced it was increasing the maximum penalty for serious and other than serious citations to $13,260 and the maximum for repeat and willful violations to $132,598.
That means conducting a safety audit is especially critical if you’ve already received citations at any company facility, since a repeat offense could trigger a costly willful violation.

This is the last year that R22 can be manufactured in or imported to the United States.
As a reminder, here’s the timeline according to the EPA final rule:
- On January 1, 2018, R22 production dropped 30% from the 2017 supply to 9 million pounds
- On January 1, 2019, production dropped 55% from the 2018 supply to 4 million pounds
- On January 1, 2020, R22 will be phased out completely with no new or imported R22 allowed in the U.S.
If your refrigeration system uses R22, you have some decisions to make — and the clock is ticking.

Stellar is gearing up for ATMOsphere America 2017, the leading forum for discussion about the business case for natural refrigerants in North America. The three-day conference next month will host more than 400 industry stakeholders in San Diego, California, and will feature discussions about the latest in refrigeration technology and regulation. Among the hot-button issues in the industry: the diminishing role of hydrochlorofluorocarbons (HCFCS).

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.
Takeaways from the Process Cooling webinar
Sep 3, 2015
Recently, Process Cooling hosted a fantastic webinar on ammonia safety, discussing practical advice for industrial refrigeration system operators. As ammonia usage continues to grow with the changing refrigeration landscape, it’s important for all of us to understand ways to keep our plants and personnel safe.
5 key sessions from the annual refrigeration conference
Jul 16, 2015
I recently joined hundreds of refrigeration stakeholders in Atlanta for ATMOsphere America 2015, an annual natural refrigerants conference. Stellar was among the 37 sponsors, and I among the group of 60-plus speakers, leading a presentation on the advantages of packaged refrigeration equipment. I also attended several sessions myself, leaving the conference with valuable takeaways on the refrigeration industry, including my favorites below:
