Recuperators with EC fan

EC fan

— this term refers to fans with synchronous brushless motors, also known as EC motors. Such motors are more advanced than traditional asynchronous ones: in particular, they provide very uniform rotation, allow precise speed control, have high efficiency, generate almost no heat (which is extremely important in the presence of a cooler), and also operate efficiently over a fairly wide temperature range. In addition, the noise level of such motors is noticeably lower, and the service life is longer. The main disadvantage of EC fans is the traditionally high price.
