In this month’s troubleshooting situation, we have a customer who has called to say that their condominium has no heat. The particular equipment in this case is a thru-the-wall package unit that provides cooling in the summer and employs a natural gas system to heat the building in the winter.
Driven by variable-frequency drives, the Gen2.0 PremiumPlus+™ brushless permanent magnet motors have motor-only rated point efficiencies of 93 percent and 92 percent for 3- and 5-hp versions respectively. They are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution.
When it comes to motors, drives, and variable speed technology, manufacturers keep rolling out new products designed to increase efficiency. Here are just a few of the latest offerings that contractors may want to consider.
Today’s high-efficiency furnaces rely on high-tech components to run efficiently. Although maintenance tips are few and simple, it never hurts to keep these tips fresh in the minds of service technicians.
The Eon 42 is a more energy efficient solution for the standard PSC motor found in many fan coils and blower deck applications today, saving up to 56 percent of the electricity consumed by the motor, says the company.
High-efficiency furnace motor Rescue EcoTech® dramatically upgrades the electrical efficiency of a furnace while lowering operating costs and improving comfort. Through its patented design, an ECM motor connects directly to the furnace board in just the same way as the existing PSC motor it is replacing.
The Eon 42 variable-speed, constant-torque motor is designed for direct-drive blower applications such as fan coils, kitchen ventilators, air curtains, and unit heaters/coolers. According to the manufacturer, the motor saves up to 56 percent of the electricity consumed by the motor.
Four replacement iMotors have been added to the iMotor line of electronically commutated motor (ECM) products. The motor design now has a total of 14 motors.
