Advantages

• Very high degree of efficiency UP to 90%

• Integrated controller (continuous control)

• Additional functions (pressure control, airflow, speed, temperature, air quality, etc.)

• Smaller-sized motor for the same level of performance

• Less power consumption

EC-fans are up to 30% more efficient than AC-fans

EC motor efficiency ranges between 80% and 90%. To put this into perspective, a three phase induction motors maximum efficiency is at 75%, and PSC (permanent split capacitor) motors have a maximum efficiency of between 60% and 70%.

EC-fans have a longer lifespan

EC motors’ high efficiency also means that the motors run "cool", and dramatically reduce the amount of waste heat produced. Reduced waste heat at the evaporator motor level also typically results in reduced operation at the compressor level, which allows further energy savings. Further, running cooler improves the life of highly loaded motor parts like windings and bearings.

EC-fans have a wider operating range

EC motors also have a wider operating range than traditional induction motors, which means that one ECM motor can replace a number of induction motor models. In this case, the number of models required by a typical customer is significantly decreased, which decreases and simplifies inventory. This is the main reason why ECM product lines usually include less motor models than their induction. counterparts.
