Nearly 61,000 HVAC industry representatives enjoyed sun and reasonable temperatures as the 2016 AHR Expo rolled into Orlando, Florida. Preliminary numbers show that more than 18,254 exhibitor personnel welcomed 42,672 visitors.

While there are still a significant number of single-speed motors still in operation, many OEMs are making a concerted move toward variable-speed equipment in order to meet a growing demand for higher efficiency. To help OEMs meet their goals, and to meet increasingly stringent motor efficiency regulations from the U.S. Department of Energy (DOE), motor and drive manufacturers have introduced their smartest, most efficient products yet.

Eaton’s B-Line Series KwikWire Hanging System is a flexible replacement for jack chain or all threaded rod (ATR) for hanging items such as HVAC duct, a wire basket cable tray, lightweight air-handling equipment, and more.

As the DOE mandates minimum efficiency performance and the EPA delists ozone-depleting refrigerants, manufacturers are being tapped to create speed-controlled compressors that run on an array of natural refrigerants. 

Armstrong Fluid Technology introduced two new series of horizontal end suction pumps featuring integrated controls for greater energy savings. 

Hartell introduced its high-temperature, low-profile, commercial-grade PlenumPlus Series condensate pump series. 

The Little Giant Speedi Duct line set duct and accessories cover, protect, and aesthetically hide refrigeration line sets for both mini-split and ducted air conditioning systems. 

NOARK introduced the latest edition to its B1N miniature circuit breaker family: the UL 489 B1NQT. 

The second-generation Copeland Scroll variable-speed ZPV2 compressor features intermediate discharge valves to boost efficiency, optimized scroll elements for variable-speed performance, a positive displacement oil pump for enhanced reliability in low-speed operation, and brushless permanent magnet (BPM) motor technology. 

This smart actuator for Venturi air valves includes a quiet, brushless motor that includes cycle count tracking, which provides predictive analytics about the actuator and valve to facility managers.
