: Insufficient cooling airflow, low oil levels, fouled air/oil heat exchangers, or a faulty thermal valve.
The Micro Nova ES99 is a sophisticated control unit, often used with screw compressors. It is designed to optimize the performance and reliability of your compressed air system by managing operations like loading and unloading cycles, providing protection against fault conditions, and delivering real-time diagnostic feedback. The controller may also be known as part of the series of controllers, which are programmed for energy savings and automatic start/stop functions.
