AUMA PROFOX actuators are proving themselves in the district cooling network of Qatar Cool, one of the leading district cooling suppliers in the Middle East. The compact and smart actuators are installed in the district cooling network for Pearl-Qatar, an artificial island close to Doha, Qatar.

The PROFOX actuators replace actuators of a different brand which, although only a few years old, did not stand up to the process conditions. Failures in the actuator electronics were frequent, and the hard plastic gears were worn out and could no longer deliver the required torque.

PROFOX actuators proved to be the perfect solution for the requirements of Qatar Cool, thanks to their high-quality, high-precision mechanics and their innovative design. A key benefit for the customer is easy operation of the actuators via Bluetooth, using the AUMA Assistant App. This means that the actuators can be easily operated locally, even though they are installed at a height that is difficult to access. In addition, the FOX-EYE indicator light clearly shows the actuator status, even from a distance. Another key reason to opt for PROFOX actuators was their numerous feedback signals, which the customer uses for process supervision.

Five PROFOX PF Q-300 part-turn actuators are currently in operation at Cool Qatar. They control the supply of chilled water from the district cooling network to the main heat exchanger of one of the connected buildings. More are to follow.

AUMA launched the PROFOX actuator series only last year. Providing fast and precise positioning, utmost flexibility and an excellent cost-benefit ratio, the high-performance, compact actuators are suitable for all industry sectors, including water treatment, combined heat and power plants, district heating and cooling, process industries, and shipbuilding.
