Refrigeration Controls FAQs

Wednesday, December 3rd, 2025

The controls systems that operate in industrial manufacturing facilities, cold storage units, and ice arenas often go unnoticed, carefully maintaining the critical temperatures required by the product inside. Knowing your refrigeration controls equipment and software inside and out is key to effectively managing it and maximizing its capabilities. Plant managers, equipment operators, and trusted system integrators all play a critical role in keeping the equipment in the best condition. Find answers to commonly asked questions regarding industrial refrigeration control systems.

Who can service my controls equipment?

Depending on the type of equipment you have installed in your facility, only certain local contractors and system integrators are qualified to work on your systems. Proprietary controls restrict service contractors to the original installer of the equipment. No other contractors are allowed to work on proprietary equipment. Non-proprietary systems, however, can be serviced by any trusted, local controls contractor and system integrator

Can one control system manage all my industrial equipment?

Depending on the size of your facility, yes, one controls system can integrate with your entire setup. Egan Company’s Refrigeration-IQ™ controls can manage a variety of equipment in industrial manufacturing facilities, food and beverage processing plants, and even ice arenas. Every industrial facility comes with its own unique equipment and controls needs, and Egan’s trusted system integration team works closely with plant managers to understand the goals of the facility and how a custom refrigeration controls system can improve the operations in the building.

How do custom refrigeration controls improve the food and beverage manufacturing process?

By maintaining control of critical temperatures throughout the food and beverage manufacturing process, operators can ensure a higher level of quality, food safety, and consistency in their product. Custom refrigeration controls meet the needs of each individual plant, integrating equipment, processes, and temperature requirements for your processes. Monitoring the temperature range in the facility can help maintain compliance with the standards regulated by the FDA, while also reducing spoilage and costly emergencies. 

Can Refrigeration-IQ controls help ice arena management? 

Yes! Egan’s refrigeration controls experts have partnered with multiple municipal ice arenas to provide solutions for facility management. Both indoor and outdoor arenas require user-friendly controls to keep ice smooth and ensure easy management for operators. Egan has installed a number of different systems for ice rinks, based on the needs of each one. From new motor controls and glycol cooling systems to smart pulsing compressors, each ice arena may benefit from different equipment and approaches. 

What temperatures do cold storage facilities need to stay within? 

Temperature requirements will vary depending on the individual facility and the product within. The United States Pharmacopeia (USP) designates freezer storage as climate controlled facilities that maintain temperatures between -4°F and 14°F, while cold storage temperatures should stay between 14°F and 46°F.

What temperature should perishable products be stored at?

Specific products, such as pharmaceuticals, meat, dairy, or produce, each require its own storage temperature ranges. In compliance with FDA standards, keeping meats, dairy, and produce between 36°F to 39°F can help ensure safety and quality during storage and shipping of products. Keeping up to date with the latest guidelines and individual product specifications can help protect your cold storage facility and inventory. 

What happens if the temperature in my facility goes out of its set range? 

If the temperatures in your manufacturing plant, cold storage facility, or ice arena begin to increase or otherwise go out of the set range, it is critical to begin troubleshooting immediately. In many cases, the issue may be a faulty temperature sensor, a compressor not cycling properly, or a door left open, which can often be resolved by replacing the sensor, checking control parameters, or verifying door seals and alarms.

Egan Company’s Refrigeration-IQ™ controls automatically alert your team when temperatures exceed limits, helping you quickly identify and correct issues before they impact product quality, safety, or system efficiency.

Calling the company that installed the system, or another local electrical contractor and system integrator, can help solve the issue and get everything back on track quickly. Because maintaining key temperatures is so critical for industrial manufacturing and cold storage facilities, having a plan in place in case of emergencies is important. Integrating alarm monitoring, remote troubleshooting, and maintaining key contacts with local contractors are all steps you can take to keep track of the temperatures in your facility and get ahead of potential problems. 

Is ammonia refrigeration the best option for my facility?

While ammonia cooling systems are common for maintaining refrigeration temperatures in industrial settings, they are not the only option, and in some cases are not the best option for processing plants and storage facilities. 

The benefits of ammonia systems include effective heat transfer, energy efficiency, and low environmental impact, making it an ideal solution for many large-scale manufacturers and industrial plants. Alternative options include glycol cooling, carbon dioxide systems, and synthetic refrigeration systems. Each industrial refrigeration system has its own benefits, including energy efficiency, safety, and low-temperature capability.

The End of an Era

Tuesday, November 14th, 2017

Since 1946, a Minnesota manufacturing facility has relied on the same two synchronous motors to power its plant. But now, after 70 years, the time has come to get an upgrade. Egan provided its expertise in constructing the electrical installation of two, newer, more modern squirrel cage motors at the manufacturing plant.

“Given the age of the motors, the price to replace instead of repair them was actually more cost effective,” said Paul Meier, Egan Company Project Manager.

Facts about the motors:

  • The synchronous motors had a voltage rating of 2300 volts and ran at a constant rate of 200rpm. These have now been replaced with modernized conventional motors that can function up to a rate of 1800rpm.
  • In addition, the new motors have a voltage rating of 480 volts. With the help of gear reduction, they can still maintain the desired rate of 200rpm while providing much less stress on the machine.
  • The horsepower of the synchronous motors was 350hp and 500hp while the new motors are each 400hp.
  • Lastly, the new motors are half the size! The synchronous motors towered at seven feet high while the squirrel cage motors stand around three feet.

Egan’s team provided all pre-installation wiring of distribution gear and soft starters for the project. The soft starters temporarily reduce the load and torque of the power and electrical surge of a motor during start-up. In turn, this reduces the mechanical stress on the motor and shaft, which extends the lifespan of the system.

“The soft starters for these motors are an important piece to this project,” said Meier. “These will be a big factor in the longevity of the new systems.”

In addition, Egan helped coordinate the facility shut downs to install each of the motors. This included the logistics and functionality of allowing the facility to run off of one old motor and one new motor congruently in-between the two shutdown periods.

Local Expansion Helps CHS Grow

Thursday, December 17th, 2015

150721_Egan_L_191Minnesota is the fourth-largest agricultural exporting state in the country. About 54 percent (or 27.6M acres) of the state consists of farmland. That’s close to the total acreage of Tennessee (26.9M acres). For home-grown grain products, Cenex Harvest States (CHS), a Minnesota-based multinational agricultural cooperative, relies on a vast network of roads, railways, and river transit to export around the world.

An important step in the distribution process is the system of grain-handling terminals, or “grain elevators,” where corn, soybean, and wheat can be stored and later moved onto river barges by conveyors. In 1982, CHS opened a multiple commodity grain-handling terminal in Savage, Minn., with a storage capacity of 560,000 bushels (or roughly 31.4 million lbs. if using only corn). That capacity more than doubled this past year with the construction of a new 801,000-bushel bin.

CHS moves more than two billion bushels of grain annually, so efficiency is key. Without an efficient transportation network, farmers could not compete on an international scale. That’s why expansions must be strategic and well executed.

When it came time to choose who would provide automation for the new bin, CHS Savage Terminal Manager Greg Oberle knew Egan held a distinct advantage.

“The work that Paul Meier [Project Manager], Todd Voth [Electrical Foreman], Darin Shaw [Electrical Foremen], Joe Trosen [Controls Engineer], and Mark Thomas [Electrical Foreman] have performed for us is outstanding,” said Oberle. “We already knew they were a good fit for the expansion, based on past experience.”

The experience Oberle mentions is in reference to a full-scale software update that occurred in 1999. The then-current PLC/3 control system had become out-of-date. CHS hired technicians from Industrial Electric (since acquired by Egan) to upgrade the system with new ControlLogix and RSView software. After a successful installation, the business relationship continued to stay strong through the years.

“The whole operation has been Egan’s baby since the update,” said Oberle. “The Egan crew works hard to make sure they come to me with solutions, not just issues. That kind of relationship is what wins you the first major expansion to this facility since it opened in 1982.”

The new bin is a 105150721_Egan_L_202-foot wide cylinder that stands 99-feet tall at the eve and 128 feet at its peak. Egan installed two new motor control centers for product supply and control motors for conveyance to-and-from the new bin. Todd Voth, who lives in the area and is frequently called on by CHS to tend to the facility’s many-faceted needs, played a key role in the technology integration effort.

“Automation-wise, grain elevators are definitely more complex than most people might think,” Voth said. “It’s a process with many coordinated steps to move grain that efficiently, and any missteps can lead to angry grain haulers and lost business.”

The substantial increase in storage frees up business options for CHS. Deliveries that used to have to wait until a barge arrived can now freely move product to the facility without delay. The new bin is also designed to help railroad cars load more efficiently.

The bin officially opened in May 2015, after five months of construction. The facility can now efficiently store and manage about 1.36 million bushels of grain product, and continues to receive dedicated service from Egan personnel.

Summit Brews in Newest Expansion

Tuesday, June 9th, 2015

2015_SummitBrewingExpansion (9)The Summit Brewing Company has seen popularity and demand skyrocket in recent years. Though they’re well-known for producing craft beer, they are by no means a small operation. The Summit headquarters in St. Paul, Minn., is the 28th largest brewery in the U.S., and it’s where Egan recently completed a revamp of electrical infrastructure for their newest expansion.

Summit began their ambitious development initiative in 2012, which included construction of a brand-new cellar (prior to Egan involvement) and then the purchasing and repurposing of an adjacent facility. The refurbished facility contains several new additions, and the entire electrical layout needed to be rearranged to accommodate the new equipment.

“Summit leaned on us to make the facility mesh together well,” said Mitch Schanus, Egan Company Foreman, “which is crucial when you’re looking to house an office, bar, and brewery environment in one building.”

When Summit’s primary electrical person retired several years ago, Egan was brought on thanks, in part, to an old connection. Egan Project Manager Randy Kalthoff and Summit COO Tom Thomasser had worked on a construction project together twenty years earlier in La Cross, Wisc. Kalthoff recognized the name on a project bid and reached out soon after.

“Tom and the Summit team started with a pretty general layout in mind for the building,” said Kalthoff. “Our expertise helped fill in the gaps to get them the most out of the space available.”

Egan worked with Summit’s broad specifications to essentially design and build the entire facility’s refurbishments.
The grand opening for the revamped facility took place in April, with Egan and Summit employees, beer enthusiasts, and St. Paul Mayor Chris Coleman in attendance. All of Summit’s facilities now receive regular maintenance from Egan electricians, a pleasant task when paired with a quick trip to the beer hall after a hard day’s work.

The Summit Brewing Project is a refurbished, 40,000 square foot, industrial/office facility with 3.5 acres of land. The work entailed complete rewiring, upgraded main service, new LED lighting, and a remodel of infrastructure for the office, training room, kitchen, and bar areas.
