Airleader has been instrumental in commissioning air management controls to minimize down time and reduce maintenance cost. The Airleader controller was installed in 2014 and has helped greatly to achieve compressor management and efficiency of 90 to 95% reducing loading and unloading cost. The controller needed a new firmware upgrade and Air leader service engineer Jan Hotzel was prompt and thorough in performing the upgrade. His knowledge and help were greatly appreciated to get the controller up and running. Jan is extremely knowledgeable of the controllers and provided information regarding new features, upgrades implemented in the lates 4th gen controller. We are really delighted to receive the personal prompt and dedicated response from the knowledgeable team at Airleader.
