Square Duct Fan Galvanized Steel Design Suitable For Various HVAC In Central Asia

AC vs. EC
AC motors are designed to operate at a certain point on their performance curve which coincides with their peak efficiency. Either side of this operating point, the efficiency can drop off considerably. EC motors on the other hand have an almost flat efficiency curve which varies relatively little across the speed range, a range which is not limited by synchronous speeds or as susceptible to voltage fluctuations as an AC motor. This makes the EC fan much more flexible in terms of being able to use the same product to match the performance requirements of different applications while still benefitting from increased efficiency.

The available range of AC input EC fans is expanding all of the time. There are axial and centrifugal fans, forward curved and backward curved, single inlet and double inlet, single phase and three phase and they are often directly interchangeable with their AC equivalents. EC offers the OEM more than just energy-efficiency. It is an opportunity to bring new technology and functionality to their products. With ever-increasing demand for energy efficient systems, when it comes to fan based products, there’s no reason for manufacturers not to have any in their portfolio.
