How it works - Natural Gas Flow
Fluid at atmospheric pressure gravity feeds down from the surge tank through the exchanger efficiently absorbing the catalytic heater’s radiant heat energy. Hot fluid is then transferred to the suction of the pump which circulates 1 - 5 gal/min through the heat-tracing loop returning cool fluid back to the surge tank where it is temperature controlled and preheated before repeating its cycle.
Surge tank is equipped with a built in thermowell where the catalytic heater’s thermostat temperature controller’s sensing bulb is inserted to sense and maintain system return fluid temperature of 10-40 C. When system reaches set temperature, the thermostat controller will adjust fuel supply to catalytic heater, utilizing only what it needs from catalytic heater to maintain system temperature.
The Radiant Tracer is also equipped with a built in high temperature shut down controller designed to completely shut off fuel supply to catalytic heater in an event the system is overheated, protecting the system and associated components.
