Evacuation is often called “vacuum” or “pulling a vacuum,” and it’s one of the most important parts of the HVACR installation and repair process where the refrigerant circuit is involved. Our goal should be to keep the closed refrigeration circuit clean, dry, and tight — just like I was taught since the very first week of HVAC school.
Regal Beloit Corp. has become an expert in FER compliance by redesigning its products to meet the new standards, including the Genteq® Ensite® motor, DEC Star® blower assemblies, and a new electronically commutated motor (ECM) to provide FER compliance for entry-level fans. These products were on display at the 2019 AHR Expo.
Location isn’t everything, but it helps. Just ask homeowners selling their property, or restaurant owners. In the HVAC world, it also rings true for some motors and drives and the professionals who work with them. That includes contractors, even if maybe not in the way that one would expect. Some current and next-gen drives will make location matter in a new way: Contractors can spend more time further away from the equipment itself.
For HVAC pros interested in motors and drives, Tuesday afternoon at this year’s AHR Expo in Atlanta featured a good chance to give the feet a rest and focus on the mind for a while. Air-Conditioning, Heating and Refrigeration Institute (AHRI) presented a three-phase session called VFDs: Method of Laboratory Test and a Case Study.
When Independence Day rolls around this year, many manufacturing leaders will fire up the grill with a sigh of relief. Not only will they have the day off, but they will enjoy the first day of freedom from what has been five years of preparations for the first national efficiency standards for furnace fans.
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.
Judging by the emphasis in the AHR booth, Panasonic is working to differentiate itself by putting considerable emphasis on health and IAQ. Even though it is not scheduled to reach the U.S. market until early 2020, the offering getting the most attention this year was nanoe™X.
Nortek is celebrating its 100th birthday this year, but judging by the breadth of activity across its various operations, it’s moving like a company half its age. It is also using some perspective in an effort to position itself to make the most of facility trends.
