Emerson Commercial & Residential Solutions

In today’s dynamic commercial refrigeration and AC markets, contractors are faced with an ever-increasing variety and complexity of applications. Whether you’re a seasoned technician or new to the trade, you need every advantage when troubleshooting and diagnosing issues for your customers. Service technicians have access to the latest technologies in their toolkits available to them on their mobile devices.

One such tool is the Copeland Mobile app.

Access the product database

The Copeland Mobile app connects contractors to the Emerson Online Product Information database for on-the-go access to 30 years of Copeland compressor product specifications. This feature-rich app helps contractors perform the following actions in the field:

  • View product specification and application engineering manuals
  • Cross-reference Copeland products with other compressor brands/models
  • Quickly troubleshoot and diagnose Copeland compressors
  • Check the availability of local product replacements

The Copeland Mobile app is designed to give you instant access to the product, installation and service information you need to service your customers. Simply scan the barcode on any Copeland compressor to pull up its specifications or quickly find the Copeland replacement of a competitor’s model.

Connect to the industry’s largest support network

When you launch the Copeland Mobile app, you’ll immediately connect to the industry’s largest support network, comprised of more than 1,000 Copeland-authorized locations and over 600 certified Copeland technical specialists. If you have additional questions about customer service, product support or availability, representatives from our American base of operations can quickly deliver the product and technical assistance you need.

Make your job easier and our products better

While the Copeland Mobile app is designed to make your job easier in the field, it’s also contributing to the research and development of future Copeland compressors. Every time you use the Copeland Mobile app, you’re helping us contribute to a database of product and competitive information that we’re using to build better compressors.

So, if you’re ready to learn more and add valuable tools to your utility belt, view our Copeland Mobile app video, and then click the link to download it.

Electronics Help Get the Job Done

The HVACR industry continues to see advancements in electronic technologies and these advancements are quickly changing the game for contractors in the field. For example, when Emerson began transitioning from mechanical to electronic controls in refrigeration equipment in 2012 by replacing mechanical controls on Copeland™ condensing units with its Electronic Unit Controller, contractors and technicians quickly experienced the impact.

Today, Emerson has more than 60,000 Electronic Unit Controllers installed nationwide on its new Copeland Scroll™ FFAP condensing unit and its currently offered Copeland Scroll™ Outdoor condensing unit (XJ Series), and it is easy to understand how everyone in the service channel benefits from this simple switch. The technology is designed to enhance productivity without sacrificing accuracy. Contrary to the traditional, 25-minute set-up time required for mechanical control switches, the Electronic Unit Controller requires only one minute or less. Wholesalers also see firsthand the impact the transition has made. For years, equipment and service problems were associated with increased cost and time. Today, electronic technologies, like the Electronic Unit Controller, eliminate common equipment problems and reduce callbacks, making it possible to provide unprecedented levels of customer service and support.

Compressor Electronics Provide Protection for Adverse Operating Conditions

Many of us are familiar with the metaphor that the compressor is like the heart of an HVAC system.  The “heart” behaves inefficiently with irregular patterns when particular conditions exist within the system that drives the compressor outside of its normal operating parameters.   CoreSense™ technology for Copeland Scroll™ compressors is designed to detect this irregular heart beat much like an EKG monitor does during a visit to the doctor.  Many of the common excursions outside of the operating envelope, like loss of charge, low suction pressure, high discharge pressure, and overcharge, can be detected and ultimately prevented with the proper application of CoreSense technology.  Protecting the compressor and shutting it down before a catastrophic incident saves valuable time and money throughout the service channel.

The following graphic depicts a typical compressor operating envelope for a residential air conditioning application.  The area highlighted in green is where the compressor is designed to operates in the most efficient and optimal way.  Prolonged operation outside this region can lead to significant compressor and system damage.  Four typical operating excursions, the possible causes, and the end of life compressor scenario are denoted around the perimeter of the envelope.  The application of CoreSense technology will proactively detect these excursions and prevent them from causing unwanted damage and costly repairs.

59-Year-Old Finally Retires

You may not think that retiring at 59 is a big deal, but when you are talking about a Copeland™ brand condensing unit, that’s pretty special.  I recently received an email from a retired owner/contractor, Tom Hall from Owen Sound, Ontario inquiring about the age of a Copeland brand condensing unit (“Copelametic”) he has had in is home walk-in for over 41 years!  He rescued it from a meat market all those years ago after a fire consumed the building.  We get these type of inquiries from time to time, and it’s always enjoyable talking with our long time customers and digging into our archives to try to uncover the manufacturing date of the equipment.

To the best of our knowledge this ¼ HP Copelametic condensing unit was built in 1954 meaning it has been in operation for almost 60 years!  Tom recently retired the unit due to the relay finally giving out, but the compressor was still running strong. 

Is anyone in need of a Copelametic compressor replacement Part #HF25I for a 1954 condensing unit?  I have Tom’s number (just kidding). 

It’s great to hear the stories of longevity of our products.  Tell us your best Copeland brand story!  Can you beat Tom’s?

“Drop In” Refrigerants Can Drop You Out of Warranty: Why Refrigerants Matter

Usually anything promoted as a quick fix tends to lead to a long term problem. We think that’s the case with the so called “drop in” R-22 replacement refrigerants. These “drop ins” claim to offer the same performance characteristics regardless of whatever remaining mineral oil is left in the system from the previous R-22 charge. While certain OEM applications have been approved for use with certain Copeland™ brand compressors, this is far from a ‘blanket’ approval for use in all compressors and you should proceed with caution.

Our Position
Copeland™ brand products are not recognized by U.L. when used with these R-22 replacement refrigerants in air conditioning applications.

It is also noted that these refrigerants are immiscible with 100% mineral oil and that this can lead to insufficient oil return from the system and potentially inadequate oil level in the compressor during operation. For these reasons, Emerson will not be granting “blanket” application approval of refrigerants for use with100% mineral oil in air conditioning service applications.

Emerson further recommends that refrigerant guidelines provided by the OEM should be followed in all cases. In fact, the non-authorized use of alternate refrigerants may have significant detrimental effects on the operation of the unit and may void the OEM compressor warranty.

In cases when OEM guidance is not available, or an emergency retrofit is required because of critical cooling needs, Emerson recommends the use of R-407C with POE oil as the best available option when transitioning away from R-22 in service applications. This refrigerant-oil combination is fully miscible and has performance characteristics that are close to R-22. For more detailed information on this subject we encourage you to visit Emerson’s Contractor Connection™.
