We are passionate about heat exchange and challenging projects. ABB Switzerland offered one of those challenges when they wanted a temperature-controlled Air-Cooled Water Cooler.
Our customer wanted to control the duty of their system by keeping the outlet temperature between certain threshold values to protect the rest of site equipment. We used a system that regulates the duty of the Air-Cooled Cooler based on the outlet temperature by varying the fan speed. This system reduces sound emission as well as the power consumption throughout the year.
Bronswerk Heat Transfer had already helped ABB Switzerland with several projects. They know that we can deliver more than just the equipment. We therefore started engineering a solution that fully met all their needs and requirements.
We designed a temperature sensor that measures the temperature at the outlet of the Air-Cooled Cooler. This information is transferred to a programmable logic controller or PLC. This PLC uses the information to calculate the necessary fan speed, which is translated to a control signal and sent to the VSD, keeping the outlet temperature between the required values. The result: they can now control the duty of their system.
