Heated Regulator is designed to supply heat to samples entering instrumentation systems. It can be used to preheat liquids, to prevent condensation of gases or to vaporize liquids prior to gas analysis. It consists of heat exchanger and pressure control sections. The pressure control section is patterned after the time proven design of the PR-1 pressure-reducing regulator and provides the same excellent outlet pressure stability. The heat exchanger section is made up of a body and heat exchange element. The electrical components of this unit are securely housed in a Class A, B, C, D condulet assuring that there is always an adequate flame path between the environment and the controller. Its operating temperature is up to 380° F (193° C). It has modular pressure control and heat exchanger assemblies for easy maintenance. These are available in 110VAC or 240VAC.
