The Copeland™ Hermetic CS compressor line has been extended for use with leading alternative refrigerants. To learn more about this important update, read our recent E360 product spotlight.

Copeland Hermetic CS compressors are commonly used in self-contained and remote walk-in coolers, as well as in ice, soft serve and frozen carbonated beverage applications. Most recently, we’ve updated this industry-standard compressor platform to qualify for use with modern refrigerant alternatives — which include R-407A, R-448A and R-449A — to offer lower glower warming potential (GWP) while providing the same reliable performance.

Found in a wide range of commercial refrigeration applications, R-404A is one of the most commonly used hydrofluorocarbon (HFC) refrigerants. In recent years, HFCs like R-404A have been targeted for phase-down via global, federal and state regulatory efforts to limit the use of high-GWP refrigerants. Throughout the industry, many operators are actively seeking lower-GWP options to help them achieve regulatory compliance and meet corporate sustainability initiatives.

Many factors must be taken into account when considering how to transition to a lower-GWP alternative refrigerant, including service, maintenance and operational requirements. It’s no surprise that many operators are hesitant to transition to an option that will force them to overhaul their current refrigeration architecture or introduce a new compression platform. Emerson is helping those familiar with the Copeland Hermetic CS compressor line move from R-404A to one of these approved alternatives — without introducing new system complexities.

For those seeking to comply with regulatory targets or meet sustainability objectives, Copeland Hermetic CS compressors are qualified to use R-407A, R-448A and R-449A in medium-temperature applications. This will enable significant GWP reductions compared to R-404A.

R-404A 3,922 GWP
R-407A 2,107 GWP
R-448A 1,273 GWP
R-449A 1,282 GWP

Retrofit vs. new: considerations
With these new refrigerant qualifications, operators now have the option to retrofit their legacy Copeland Hermetic CS compressors. It’s important to understand that R-407A, R-448A and R-449A are not considered true “drop-in” replacements.

Even though operators can keep the same compression platform, switching from R-404A to one of these lower-GWP options requires adherence to Emerson’s Refrigerant Changeover Guidelines to help ensure optimum system performance. Expansion valve adjustments, proper lubrication and filter changes must be followed per the application engineering bulletin.

For new applications, this newly qualified Copeland Hermetic CS line of compressors grants operators the flexibility of determining which replacement options are best suited to meet their external regulatory requirements and/or internal sustainability initiatives. Emerson recommends consulting its application engineering bulletin or a certified compression expert to help better understand the performance characteristics of each low-GWP refrigerant option.

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.

Back to the Future

Twenty-five years ago The Last Emperor won the Academy Award, gas was less than a dollar a gallon and the U.S. Department of Energy was establishing new efficiency regulations for the HVAC industry.

At the time, the industry was using reciprocating compressors in 8 SEER systems. Proponents for the new efficiency standards acknowledged the limitations of existing compressors and it was clear we needed a breakthrough technology that could deliver higher efficiency levels.

On November 14, 1987, Copeland officially became the first U.S. manufacturer to produce scroll compressors for use in the residential air conditioning and heat-pump systems. The industry quickly recognized Copeland Scroll™ compressors as the revolutionary leap in technology needed to achieve the efficiency levels required by the government.

copelandFast forward to today. The minimum standard is now 13 SEER, although manufacturers, still using Copeland Scroll technology, are producing AC and heat pump systems that surpass 20 SEER. The technology that helped revolutionize an industry 25 years ago is still going strong; over this period Emerson has produced 100 million Copeland Scroll compressors in nine manufacturing facilities spanning three continents.

As we have celebrated our milestones these past few months, the most exciting conversations I’ve had with manufacturers and contractors are focused on where we’re going with the future of scroll technology. Copeland Scroll compressors continue to play an important role in improving efficiency in the industry. We see modulating technology as a key part of our present and future strategy to offer high energy efficiency without compromising comfort. And compressor electronics, including Emerson’s innovations, are becoming critical as we look to use the compressor as a sensor to offer enhanced diagnostics, communication and protection capabilities.

I’m proud to have been part of the team that brought Copeland Scroll technology to market. The industry was at a turning point and we knew we had developed something that would change the future of HVAC.
