Outdoor condensing units (OCUs) have been a mainstay for small refrigeration applications for decades. In an upcoming webinar, we will review recent OCU technology innovations that utilize digital compressors to achieve the many benefits of variable-capacity modulation. This informative webinar will take place on Tuesday, June 9 at 2 p.m. EDT/11 a.m. PDT.
Commonly used by small-format grocers, convenience stores and restaurants, OCUs have traditionally provided refrigeration for walk-in coolers, display cases and food preparation rooms. By equipping this proven refrigeration strategy with digital compressors, OCUs can provide a greatly expanded role in refrigeration applications. We will explore these new possibilities by taking a closer look at Emerson’s Copeland Digital Outdoor Refrigeration Unit, X-Line Series.
Instead of providing one refrigeration load per unit, the digital X-Line allows operators to service multiple refrigeration loads with one unit — potentially eliminating the need for multiple condensing units. In addition, their ability to modulate capacity per refrigerated load requirements enables precise temperature control and load matching for maximum energy efficiencies.
Webinar attendees will learn how the digital X-Line delivers major advancements to outdoor refrigeration:
Fewer units to install and maintain
Tight temperature precision
Simple and quick commissioning
Lightweight and flexible installation options
Reduced costly call-backs via advanced diagnostics
Lowered refrigerant charge and line sets
Unlike traditional OCUs that utilize a fixed-capacity compressor, the digital X-Line enables continuous capacity modulation from 20 to 100 percent to deliver significant reductions in energy consumption and refrigeration improvements. This advanced compression technology — combined with variable-speed fan motor control, large-capacity condenser coils, and smart protection and diagnostics — provides operators with a state-of-the-art OCU solution that’s ideal for meeting today’s challenging refrigeration requirements.

National STEM Day is Nov. 8. From Emerson’s perspective, it’s a day to recognize the importance of science, technology, engineering and math — not only in our education curriculum, but also in the heating, ventilation, air conditioning and refrigeration (HVACR) industries.
Bringing the Need for Qualified Technicians Into Focus on National STEM Day
With the commercial refrigeration industry evolving to utilize more sophisticated technologies, technician jobs are becoming more technological than mechanical — and becoming viable options for those pursuing a STEM career path. A new workforce recruitment initiative by the Heating, Air-conditioning and Refrigeration Distributors International (HARDI) is addressing the technician shortage head-on via a new full-length documentary.
HVACR supply chain feeling the impacts
The impacts of the service technician shortage are being felt throughout the HVACR supply chain. While the vast majority of HVACR contracting business owners today are actively looking for technicians, this pain has far-reaching consequences — from wholesaler distributors to end users, owners and operators. Whether you’re operating a supermarket, c-store, restaurant or virtually any facility that has HVACR needs, the lack of qualified technicians is making it increasingly difficult to find reliable sources for new installations, routine servicing or emergency repairs.
And while industry stakeholders have been sounding the alarms for nearly a decade, it’s a problem that’s not going away. According to the U.S. Bureau of Labor Statistics, HVACR mechanic and installer jobs are expected to grow at a rate of 15 percent nationwide through 2026.
A perfect storm of market trends, technological advancements and demographic changes are compounding the issue. This is especially true in refrigeration, where shifting store formats and environmental regulations have led to a proliferation of system types. These systems are introducing connected technologies, electronics and alternative refrigerants, many of which represent completely new servicing procedures. As the industry struggles to attract a new generation of recruits, many of our current service technicians are scrambling to keep pace with these system changes, or are planning for retirement.
HARDI releases “Hot Commodity”
The goal of HARDI’s new workforce recruitment initiative is to spread awareness of the HVACR wholesale distribution industry to the younger generation and encourage these individuals to pursue an HVACR career path. To spearhead this effort, HARDI is releasing a documentary that exemplifies their mission and explores the many HVACR-related career opportunities.
While the full-length film has yet to be released, HARDI is currently promoting a short trailer of the documentary. As one of the professionals featured in the film states, now’s the time “for the younger generation to carry the ball” forward.
The themes presented in the documentary include:
Alternative to traditional college — Many high school students are encouraged to attend college, even if it’s not necessarily the best fit. Vocational and technical schools offer an alternative to traditional college, while allowing attendees to begin earning a living as they learn.
Financial viability — With a median annual salary of $47,080, HVACR technician profession earnings are significantly higher than other occupations, even though the job doesn’t require a four-year degree. As one of the contractors in the film explained, it’s possible for service technicians with 10 years of experience to earn as much $100K per year. Increased demand for these jobs is driving salaries upward.
Variety of career paths — Whether you’re coming out of high school, or college, or seeking a career change, there are multiple opportunities and positions to explore. For example, the film mentions a microbiologist who sought a career change offering the potential to achieve ideal indoor air quality.
Changing perceptions — The perception of working in a dirty, dark and dangerous environment is changing. The next generation of HVACR technicians will work with rapidly changing, emerging technologies, electronics, computers and more.
Evergreen market — Achieving ideal air quality and reliable refrigeration in a dynamic market is an evergreen opportunity. As a result, HVACR professions are among the most sustainable across all occupations.
As a HARDI supporter and long-time champion of this cause, Emerson will continue to do its part to raise awareness of the technician shortage facing our industry. Our Educational Services group frequently partners with vocational and technical schools to donate equipment, offer training and career advice, and even judge HVACR-related competitions. Look for the full HARDI documentary to be released later this year.

The family-owned Kelley’s Market chain, founded in 1926 and based in Rockford, Ill., prides itself on running crisp, clean stores offering top-quality products and outstanding service. They’re also astute businesspersons, highly focused on operational issues such as energy efficiency, maintenance and product protection. But they had another priority when designing and building a new store in their hometown: being a good neighbor. Read the full Convenience Store News article here.
Kelly’s Market put a high value on finding a refrigeration solution that would be efficient, attractive and quiet for the best possible customer — and neighborhood — experience. So when their refrigeration contractor walked them through the energy efficiency, maintenance and product protection of the Emerson product line, one aspect of Copeland Scroll™ Outdoor Refrigeration X-Line Units caught their attention: their ultra-quiet operation. They operate up to 16 dB quieter than traditional outdoor units — roughly the difference in volume between a vacuum cleaner and a friendly conversation. They were intrigued by the idea that by moving units outdoors they would also reduce noise in both their neighborhood and their store and wanted to learn more.
Lowering the volume while lowering energy costs
Emerson’s Copeland Scroll outdoor walk-in refrigerator technology offered energy-efficiency levels that could lower their energy bills by nearly 33 percent, plus built-in diagnostics to enable better service. Their ultra-quiet, variable-speed fan motors and internal baffling cut compressor noise by more than 50 percent.
Advances in walk-in refrigeration technology in a single unit
Copeland Scroll Outdoor Refrigeration X-Line Units range in power from ¾ to 6 HP, making them a great fit for the needs of Kelley’s Market. They chose one X-Line unit to power their walk-in freezer, one for their walk-in cooler, and one dedicated for a merchandising display case. By using outdoor units instead of self-contained or other indoor refrigeration systems, they would lower the heat load on their building’s HVAC system — further lowering energy bills.
Designed to be great outdoors
The new X-Line units were encased in a lightweight, slim enclosure that could be wall mounted, so they could place their units in locations previously not available, without the need to rent a crane for installation. In addition, the clean design of the outdoor units offered a more aesthetic atmosphere for neighbors and customers alike.
Walking into savings
The Copeland Scroll Outdoor Refrigeration X-Line Units at the new Kelley’s Market store was their first foray into scroll compressor technology. From the day the store opened, the company saw major operational benefits. In just one year, the X-Line Units delivered energy savings of 29 percent compared to their legacy store technology, with the three Copeland Scroll X-Line Units inside saving about $2,500 in energy costs per year — a significant long-term savings for a company operating nearly 50 stores.
In the market and throughout the neighborhood, the energy efficiency and optimum performance of the Copeland Scroll Outdoor Refrigeration X-Line Units are humming along quietly — just the way Kelley’s Market likes it.

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.
GWP by refrigerant
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.
