Through a the U.S. Department of Energy (DOE) Small Business Innovation Research (SBIR) grant, Kansas City, Missouri-based QM Power recently commercialized a high-efficiency motor for commercial refrigerators that has the potential to transform the market.

The motor’s design uses permanent magnets in a synchronous motor topology with a controller that quickly gets the motor to its targeted speed and then efficiently shifts the motor to AC power (50 or 60 Hz) supplied directly from the grid. 

The Circulator Pumps Working Group is an offshoot of the Commercial/Industrial Pumps Working Group, which convened two years ago to set standards on larger pumps.

This heavy-duty, hot-dipped, galvanized steel wall bracket is fully adjustable. It features a sliding crossbar, built-in level, and rubber isolation vibration mounts. 

This device is designed for automatic collection and removal of condensate from air conditioning, refrigeration, and dehumidification equipment installed in air-handling and plenum applications. 

This factory-mounted and wired variable-speed control is used for three-phase motors up to 10 horsepower. 

This lead-free electric automated shutoff ball valve package meets all requirements of the Safe Drinking Water Act (SDWA) and is available in ¼-inch through 1-¼ inch sizes. 

Fractional horsepower permanent split capacitor (PSC) fan motors are one of the most popular single-phase motors used in our industry, and then they fail, technicians must be able to troubleshoot and replace them.
