Improving Boiler System Efficiency O2 Trim

Raypak – INTRODUCING HO2T TRIM SYSTEM

How It Works. HO 2 T continuously monitors the oxygen level of the flue gas in the vent piping. If the O 2 level deviates from the target set point (operating curve), HO 2 T will modulate the fuel gas flow via the actuator and valve and bring the O 2 back to the target set point.. The HO 2 T System is now available in the XVers boiler. It features built-in, automatic system protection that
