Tank Thermostat 91000XT Series
for Oil Field Heaters, Treaters & Separators

The 91000XT Tank Thermostat is especially designed to control the temperature of heaters, treaters and separators within the petroleum industry. It is entirely self-contained, requires no external power source, and is the most widely preferred unit of its kind. When installed in a treater, the normally open valve will automatically close off the flow of gas as temperature increases, thereby regulating temperature within the treater. The Trerice 91000XT is ruggedly constructed with a heavy duty, die cast aluminum actuator housing. Its single seated, cast-iron valve body is fitted with a stainless steel plug assembly and soft seating Viton® o-ring to provide tight shut-off.
