5 Common Oversights in Industrial Refrigeration Compressor Maintenance (and How to Combat Them)

Compressors play a vital role in industrial refrigeration systems, serving as indispensable components. As time passes, both compressors and their bearings undergo degradation, posing a potential threat of facility downtime and consequent negative impact on your financial performance. To guarantee the consistent and efficient operation of this equipment, the implementation of a rigorous maintenance program becomes imperative.

Staying on top (or even ahead) of maintenance will prolong the compressor’s life and avoid a shutdown. In fact, 82% of manufacturing companies have experienced unplanned downtime, costing as much as $260,000 an hour, according to one study

Choosing the Right Oil-Cooling Method for Your Industrial Refrigeration Compressor

As any industrial engineer will tell you, screw compressors play a vital role in the food and beverage industry, where temperature control is critical to ensure product safety and quality. 

They’ll also tell you that these compressors require a lot of oil to work properly. This oil serves several functions, including sealing the rotors, lubricating the bearings and cooling the discharge gas. Because of this, nearly all food processors and beverage manufacturers will be in the market for a refrigeration compressor rebuild or replacement at some point or another. 

And while regular maintenance can help, designing a system with the proper oil-cooling technique can also extend a compressor’s lifespan by thousands of operating hours — but how do you determine what method makes the most sense for your system?

How Stocking Up (or Not) on Spare Refrigeration Parts Can Impact IIAR 6 Compliance

When using ammonia refrigeration in a facility of any kind — whether it be meat or poultry processing, frozen food production or cold storage — compliance with ammonia safety standards is a must.

The International Institute of Ammonia Refrigeration (IIAR) is a membership-based technical society focused on ammonia refrigeration advocacy, education and standards. As an accredited American National Standards Institute (ANSI) Developer, IIAR establishes the minimum requirements for safely inspecting, testing and maintaining closed-circuit ammonia refrigeration systems.

Is Your Refrigeration Contractor Pencil-Whipping Your Preventive Maintenance Program?

Temperature control is vital in the food and beverage industry, where slight fluctuations can threaten product integrity and put consumer health at risk. 

Preventive maintenance programs (PMPs) help ensure refrigeration equipment operates at peak performance, regardless of a system’s age or the refrigerant it uses.

Unfortunately, the repetitive nature of maintenance work can elevate the risk of complacency. This is extremely dangerous in the context of industrial refrigeration because even a single oversight can quickly become life-threatening.

Have you noticed your technician or contractor mindlessly checking boxes on inspection forms, failing to report daily or weekly anomalies in equipment run data, or generally failing to give your system their undivided professional attention? If so, I have bad news: you may be dealing with a pencil whipper, and you’ll want to address the issue sooner rather than later.

Is Your Refrigeration Automation Up to Par for 2023?

The development of advanced automation controls and technology for industrial refrigeration systems have made critical upgrades possible for owners who want to improve the efficiency, performance, safety and reliability of their systems and overall operations.

However, a refrigeration system running on outdated controls and hardware is like a ticking time bomb and can get quite expensive to repair — not to mention the cost of downtime.

Industrial Refrigeration Basics: Synthetic vs. Natural Refrigerants

Operable refrigerant systems have been in use since the 1830s, with ether as the original refrigerant. Over the years, the use of refrigerants has evolved as technology has advanced and research has revealed more about the impacts these substances have on the environment. 

New restrictions continue to be placed on the use of refrigerants, making it more important than ever for manufacturers, as well as commercial and industrial owners, to stay up-to-date with the latest trends and changes.

What Refrigerated Warehouses Need to Know About Ammonia Utilization in California

Source: CalARP Resource Compliance

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.

The Secret to Optimizing Your Compressed Air System

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.

How Stellar Services Industrial Refrigeration Compressors [VIDEO]

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. Continue Reading “How Stellar Services Industrial Refrigeration Compressors [VIDEO]”

Ammonia Refrigeration: Is Your Machine Room Ventilation Up to Code?

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?
