New High Wall Ductless System
Carrier recently launched a new Performance™ Series high wall ductless system including the 40MAHB indoor unit and 38MARB outdoor unit, and the multi-poise 40MBAA air handler. As the latest, fully communicative additions in Carrier’s evolving ductless line of heating and cooling offerings, the products provide versatility and energy efficiency, as well as single and multi-zone capabilities. The indoor high wall 40MAHB unit provides seasonal energy efficiency ratio (SEER) ratings up to 28.1 and heating seasonal performance factor (HSPF) ratings up to 13.0 and is available in sizes 9k through 36k. The 40MBAA boasts SEER ratings up to 20.0 and HSPF ratings up to 10.0, and is available in sizes 24k, 36k and 48k. Carrier is a part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe and sustainable building and cold chain solutions.
The 40MAHB indoor high wall unit includes the Airflow Direction feature, which automatically controls the louver direction up and down, or left and right. Other standard features include a built-in relative humidity sensor; the Follow Me feature, which allows the temperature to be changed from the handheld remote; an auto restart function; three modes of standard operation; and occupancy sensors.
The 40MAHB offers simplified installation and maintenance. Plus, increased total piping length and enhanced piping lift enable greater breadth of application and installation. There are also a wide variety of control options including a wireless remote controller, an optional wired remote controller, 24V interface and Wi-Fi kit.
The 40MAHB is backward compatible with the 38MA*R and the 38MARB is
ductless indoor fan coils. With increased flexibility and performance, including temperature control and zone air circulation, these systems can adjust motor speeds and comfort capacity as conditions change, delivering soothing, consistent temperatures and quiet operation, which can help save on energy bills.

Carrier Ductless 24V interface for the 40MBAA can be built in or stand alone.
Both options allow single and multi-zone systems to be compatible with third-party thermostats. Included features like customizable airflow adjustments and self-configuring capabilities provide application flexibility and easier servicing.
“We’re pleased to introduce both the Performance Series high wall ductless system and the 40MBAA air handler as they provide versatile and efficient choices to complement our existing line of ductless solutions,” said Paul Rebelo, Managing Director North America, Ductless and VRF, Carrier. “These models offer ease of installation, maintenance and flexibility for the contractor, while providing installation versatility, energy efficiency and multi-zone capabilities for the homeowner.”
Variable Speed Reciprocating Hermetic Compressors for Refrigeration
Emerson has introduced its Copeland™ variable speed reciprocating hermetic compressors for commercial refrigeration applications. The new models are specifically engineered to save energy and provide performance improvements in a variety of demanding commercial refrigeration applications.
Original equipment manufacturers (OEMs) in the commercial refrigeration space have faced increasingly stringent energy requirements. Medium- and low-temperature stand-alone coolers and freezers, commonly used in restaurants, convenience stores (C-stores) and small-format food retailers, have been key targets of the Department of Energy’s (DOE) energy-efficiency standards. Additionally, targeted are units used in the life science market and for small industrial applications such as process chillers. The DOE will also soon be proposing its next phase-down in energy reductions for these applications, likely to take effect in 2024. This means that OEMs are seeking a competitive edge by offering equipment that helps them achieve ENERGY STAR® certification and delivers the energy-efficiency levels that will allow refrigeration units to meet upcoming DOE requirements.
Copeland variable speed reciprocating hermetic compressors for refrigeration are comprised of two components:
- Copeland variable speed reciprocating hermetic compressor, available in ranges from 1/8 to 7/8 horsepower, which features a brushless permanent magnet motor, versus a standard induction motor.
- Copeland variable speed drive which has a smart controller integrated within it.
“The wide availability of operating ranges, combined with the breadth of the low-profile Copeland variable speed reciprocating hermetic compressor line, gives system design engineers options to select compressors that deliver optimum energy efficiency for equipment of varying types and sizes,” said Derek Langenkamp, hermetic reciprocating product manager for Emerson’s cold chain business.
Variable speed capabilities with smart controls can help deliver significant energy and performance improvements that far exceed fixed capacity options. While assisting customers in the redesign of their systems at Emerson’s test labs, they have increased system energy efficiency by 13 percent, reduced compressor cycling by 90 percent and lowered compression ratios by 43 percent compared to a high efficiency fixed speed system using propane (R-290). This means faster pulldowns to setpoint temperatures, more precise temperature holding, less wear and tear on system components and lower energy bills.
By utilizing the natural refrigerant R-290 with a low global warming potential (GWP) of 3, OEMs can offer their customers a more sustainable refrigeration option that meets some of the most stringent refrigerant and energy-efficiency regulations, including the potential impending 2024 DOE standard, California Air Resources Board standards and potential Environmental Protection Agency refrigeration requirements.

Largest Jaw Pipe Clamps for HVACR
Fieldpiece Instruments, HVACR tools and test instruments specialist, announces the launch of the largest jaw pipe clamps for the HVACR industry, the wired TC48 and the wireless system JL3LC. With an unprecedented 4 1/8-in. jaw opening the new pipe clamps are perfect for commercial and refrigeration field service professionals and also serve the residential market. The clamps, sporting a ¾- to 4 1/8-in. range, can be used on a wide variety of pipe sizes, especially in large commercial and refrigeration applications.
The new pipe clamps incorporate Fieldpiece-patented Rapid RailTM Sensor Technology making the response time to get an accurate temperature reading merely seconds, thereby enabling the HVACR pro to be more productive. With this proprietary technology, temperature readings are not affected by ambient air as the thermocouple is thermally isolated and the clamps will perform immediate reaction to changes in system adjustments as the technician is working. This can greatly facilitate taking a superheat and/or subcooling measurement on most commercial refrigeration appliances or commercial/residential air conditioners.
The versatile clamps fit virtually anywhere they need to and offer a secure connection even on wet or damp pipes. They are compact, and have an easy-to-open design that allows for quick single-handed placement.
When used with the Fieldpiece Job Link mobile app, the JL3LC makes it easy to record and share data. Their compatibility with Job Link means that the data can be displayed in a professional report to be emailed to the customer or home office.
Evac Pump for A2L Refrigerants
Ritchie Engineering Company, Inc., recently introduced the next generation of SuperEvac™ Vacuum Pumps – the SuperEvac™ PLUS II. Designed for use with A2L
systems, the integration of a brushless DC (BLDC) motor to drive the vacuum pump provides several technological advantages over AC motor driven vacuum pumps. While maintaining an ultimate vacuum of 15 microns and many of the other unique characteristics of the SuperEvac™ Vacuum Pump, the high torque BLDC motor in the SuperEvac™ PLUS II is more efficient and has a longer life. Add the ability to start and operate in severe low voltage conditions and extreme temperatures, the service tech now has a premium vacuum pump that is ready every time.
The BLDC motor is lighter weight than AC motor designs. Offered in 4, 6, 8 and 11 CFM models, the SuperEvac™ PLUS II has a 2-year warranty and is made in the USA. Ritchie Engineering Company/YELLOW JACKET® continues to strengthen its position as the premier vacuum pump manufacturer in the HVAC/R market. yellowjacket.com/products
