Flame Smart Ei+

The Flame Smart Ei+

Reliable. Advanced. Proficient. 

The Flame Smart Ei+ is designed for use with the ASHCOR combustor and can be used with various combustor and flare applications. Requiring only minimal set point adjustments, the Ei+ monitors the pilot utilizing the igniter or thermocouple as the flame-sensing device. The relighting capability ensures flame presence to maintain compliance and safe operation. 

The Ei+ is able to control both first and second stage valve as well as combustor operation based on emission vent line pressure. The temperature safety shutdown feature protects equipment and maintains optimal operation conditions. Easy startup and features such as data logging make the Ei+ an ideal choice for operations with burner management needs.
