California has long been an epicenter of food manufacturing in the United States. With more refrigerated warehouses looking to become sustainable in the 2020s, California is primed to be a major market where cold storage facilities transition to natural refrigerants.
However, “The Golden State” has unique regulations that refrigerated warehouses must follow when updating their systems. Most critically, there are strict regulations on ammonia, which traditionally has been the preferred refrigerant because of its efficiency, low cost and safety when the system is properly designed.
Busting the myth that “another compressor” is always the answer

Compressed air is a commonly used power source in manufacturing facilities, but it isn’t necessarily a cheap one. Aided by the Compressed Air Challenge movement, which started 20 years ago, users have started treating compressed air as a utility with supply and demand.
This has led to a greater understanding of how to use compressed air efficiently, but many facilities are still running on systems that are not optimized.

Stellar – Compressor Rebuild & Repair Facility (How It’s Done) from Stellar on Vimeo.
We recently updated our refrigeration parts and compressor shops in Jacksonville, Florida, and Fort Worth, Texas. (Stellar also has shops in Modesto, California and York, Pennsylvania.) Each facility offers climate-controlled storage spaces and a compressor shop with a separate teardown room, clean room and paint booth.
From the time a compressor arrives at one of Stellar’s service facilities to the time it leaves, it undergoes an unrivaled 75-point quality inspection — a rigorous examination unlike any in the industry.

When it comes to ammonia refrigeration machine rooms, ventilation updates can often be overlooked.
Current and new mechanical codes — International Mechanical Code (IMC) and Uniform Mechanical Code (UMC) — defer to IIAR 2 (and sometimes ASHRAE 15) as the referenced code for ammonia refrigeration systems, including the machine room ventilation.
Just because your ammonia system was designed to code years ago it may not necessarily be code compliant today.
If you have updated your refrigeration system recently, did you update your machine room’s ventilation as well?

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.

Summer is around the corner, which means now is the time to ensure your refrigeration system is ready for the upcoming hot months. Summertime is when these systems work their hardest, so how can you make sure yours is running efficiently and at peak performance levels?
Here’s a short checklist to prepare your refrigeration system for the summer:
