Emspro 0

The EMS PRO is a flexible all-in-one customizable unit that meets the needs of engine-driven pumping equipment applications.

The EMS PRO is a dedicated microprocessor-based, single-engine controller. It offers field-adjustable operating parameters that can be changed without the need for a computer. It is also able to support both mechanical and J1939 electronic engines. The EMS PRO has selectable auto start/stop features with several throttling options. The auto start/stop options (single contact, floats, momentary, transducer and clock) are available at the touch of a button. The transducer start/stop option includes three settings: pressure, level and temperature. In addition, there are many performance-enhancing features, all of which are available through an operator interface that is easy to learn and use.
