OPTIMIZED AIRFLOW AND MAXIMUM EFFICIENCY
Axial fans used in Ultracompact II design have outstanding characteristics in every respect, including performance and efficiency, weight, noise pollutions, and robustness.
EC fan technology is an excellent solution for demand-responsive cooling, and we equip Ultracompact II chillers with the latest EC motors which demonstrate impressive performance, low energy consumption, high torque, and durable design. EC fans with integrated electronic control can easily be varied in speed to match airflow demand. For the same air volume, they consume distinctly less energy than AC motors.
The most common cause of fan motor failure and consequent capacity reduction of the chiller is overheating. EC fans of Ultracompact II chiller have temperature sensors built into the internal electronics package that act as a safety device in the event of overheating.
Compared to AC motors, EC-type motors have a longer service life due to lower winding temperatures resulting in lower wear and tear. Comprehensive corrosion protection measures have been taken to allow the fans to be used in almost all climatic applications with outstanding operating reliability.
