AHR EXPO HIGHLIGHTS life, low-temperature “brushless” DC motors are controlled by maintenance-free electronic circuitry. In pressure-control applications, they can be direct connected to a pressure sensor. In main/secondary designs, the output of the main fan controls the speed of the secondary units. Networking is simple using a computer with an RS485 interface. Speed regulation can be achieved with a 0 to 10 V input signal or a rheostat.

The laminar airflow improves the accuracy of the airflow sensor enabling better turndown as well, the company says. Enter 319 Or email: info@tek-air.com Wellington Drive Technologies Ltd. The electronically commutated reluctance (ECR) motors and fans were designed as energy-saving replacements of shaded-pole motors used in commercial refrigerators, freezers, and vending equipment. The brushless dc motors can achieve efficiency rates up to 65 percent and ensure quiet and reliable operation, the company says. The motors and fans use the same accessories as traditional shaded-pole motors, and are available in standard refrigeration sizes and pitches for easy replacement.

Vpro is recommended for applications where high air volume at low noise levels and medium pressure is required such as roof fan units for supply and exhaust air movement, air-water heat pumps, precision air conditioning cabinets and Filter-FanUnits in clean room technology. The Vpro fans will be launched as motorized impellers with external rotor motor (in both AC and EC technology), and come in 12 sizes from 190 mm to 630 mm with air volume flow rates of 300 cfm to 8.800 cfm, and static pressure up to 4 in.

They can be produced in different shapes, including various sizes of cylindrical burners, to meet the heating needs of a diverse range of equipment manufacturers. Using both infrared and blue-flame technology, the company’s advanced gas burner systems are preferred over conventional gas burners for their high efficiency, rapid transfer and low pollutant emissions, the company says. With low-flame temperatures, the infrared burners have the lowest NOx emissions of any other gas burner available, the company says.

It offers low-pressure drop for energy reduction and savings along with safety by utilizing true airflow measurement. The AV2000 is designed for use in applications where turndowns of up to 8 to 1 are required while maintaining accuracies of 5 percent of reading over that flow range, ensuring precise airflow control.
