Troubleshooting the high side of a refrigeration system will often give service technicians valuable information. That’s because what happens in the condenser is a direct reflection of what is happening in the rest of the refrigeration system.

SPX Corporation has completed the acquisition of SGS Refrigeration Inc., based in Dixon, Illinois.

A look around the world of condensers these days shows three factors driving changes.

There are several reasons why the compressor discharge temperature of a refrigeration system can be high when the condensing temperature is not, and a checklist can help a technician figure out the root problem.

Bacharach has been in acquisition mode lately, and the company was showing off the new products and relationships that resulted from that at this year’s AHR Expo in Atlanta.

At the AHR Expo, RectorSeal LLC highlighted several new products designed to combat leaks and corrosion, both on the inside of the unit and from salty sea breezes on the coast.

Spectronics Corporation is a 60-year-old company with a new generation of Made in the USA refrigerant leak detection dye — AR-GLO 5.

While servicing equipment, technicians should be on the lookout for sources of potential future leaks, as well as follow good service practices to prevent creating leaks.

Refrigerant regulations are another reason why change is coming, as HCFCs will be phased out by 2020, and given their high global warming potential (GWP), HFCs will likely be phased down in the near future as well. At some point, supermarkets will need to start considering low GWP alternatives such as HFO blends, as well as so-called “future-proof” refrigerants such as ammonia, CO2, or propane.

Manufacturers are rolling out a wide array of new equipment that utilizes all types of refrigerants, providing end users with a number of new options to consider.

These products have refrigerator and freezer model selections including both swing and slide door refrigerators and swing door freezers.

According to the Environmental Protection Agency (EPA), a typical food retail store leaks an estimated 25 percent of refrigerant, or approximately 1,000 pounds, annually.

The Environmental Investigation Agency (EIA) unveiled a new initiative identifying U.S. retailers committed to taking leadership action to reduce HFCs.

The Refrigeration Showcase educates contractors about new refrigeration products, so they can help customers make the right choice.

As refrigerant regulations grow more stringent, manufacturers are beginning to offer new refrigeration architectures that utilize low-GWP refrigerants.

While large grocery stores are not going away any time soon, there is a new trend taking hold in the marketplace: the small-format grocery store.

Grocers are becoming more vigilant in keeping their refrigeration equipment as clean as possible.

The equipment and components in this showcase are designed to appeal to both end users and the people who work on them in the field.

The Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available.

Target and Amazon have both recently announced plans to construct new stores that contain CO2 refrigeration systems, which will help the retailers significantly reduce carbon emissions and energy use.

From ice machines to reach-ins to controls to components, the Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available, so they can help their customers make the right choice for their application.

In an informative session at the NASRC’s Sustainable Refrigeration Summit, Publix and Coborn’s shared the pros and cons of incorporating CO₂ refrigeration systems into their stores.

These Emerson half-day CO₂ transcritical booster supermarket refrigeration courses will take place March 28, 29, and 30 at the Energy Education Center in Irwindale, California.

EPA recently expanded its list of acceptable refrigerant substitutes for new refrigeration equipment to include R-471A and R-515B.

At the AHR Expo, manufacturers displayed their latest commercial refrigeration equipment, which included condensing units, components, controls, and other solutions.

A New Hampshire grocer installed the innovative FlexCube refrigeration system, a modular technology using the A2L refrigerant R-454C, in his new store.

Air conditioning and refrigeration are marvelous inventions and have a transformative impact on comfort and health, underscoring their irreplaceable role in modern living.

The most important features of electronic measuring devices have been established in customer surveys and are discussed in this article.

Technicians have the choice of using either a digital or mechanical manifold gauge. Each one has its benefits and disadvantages, which is why it may pay to own one of each kind.

Troubleshooting refrigeration systems can be complex and frustrating, so put aside any assumptions and inspect the system thoroughly before making any diagnosis.

Timely refrigeration repairs are crucial to avoid product loss; temporary fixes can sometimes keep systems running until parts arrive.

Four core components work together to control when refrigerant is absorbing heat, and when it is releasing heat.

CO₂ refrigeration systems demand both classroom knowledge and hands-on experience, which is why blending theory with practice creates top-notch technicians.

In supermarkets, where HVAC and refrigeration equipment use 50 to 60 percent of all electricity consumed, new technologies and advanced control strategies have been developed to help boost energy efficiency as well as reduce emissions.

Last year was a notable one for Testo Inc. as the test and measurement manufacturing company celebrated its 60th anniversary. However, 2018 promises to be just as momentous as Testo US will reach its 35th anniversary milestone.

Grocers are looking to their refrigeration contractor partners to be the experts and make suggestions about how they can transition smoothly to the new low-GWP refrigeration technologies.

In this episode Markus discusses with Chris Read basics and some advanced topics in the space of continuous integration. We cover concepts, some tools, as well as a number of best practices.

In this episode Michael interviews one of our regular listeners: Petri Ahonen. Petri introduces Software Configuration Management by defining key terms and describing relevant concepts.

Jeremy Jung talks with David Calavera about zero-downtime migrations and rollbacks with Kubernetes. In this episode we define migrations, rollbacks, and discuss how Netlify was able to migrate to Kubernetes and roll back off of it multiple times without impacting their users. David explains how developers can run old and new systems simultaneously, the importance of defining errors in your system, and when to apply fixes vs rolling back. We also discuss their decision to move to Kubernetes, and the benefits they received.
