Trerice 91000XTX0120-X75

The Trerice 91000XT tank thermostat is a temperature regulator specifically designed to control the temperature of oil field heaters, OTTRs (oil treater temperature regulators), and separators. 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 91000XT is ruggedly constructed with a heavy duty, die cast aluminum actuator housing and fully enclosed bellows assembly. 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.
