Economical EC-Motor Fans
Size, weight, longevity, efficiency have all contributed to select EC fans as a standard for Borrum condensers.
EC motors deliver efficiency in the narrow range from 80% to 90%, as opposed to broad efficiency range of 35-60% for AC motors, especially when operating at less than full load. This translates to significant power savings and application flexibility.
Borrum units offer fan speed management in the application using a 0~10V/PWM or 4~20mA input signal to the motor. The fans also provide a soft start and reduced running noise. Different types of diffusers are available optionally.
