Single stage pressure reducing regulator equipped with a electrically heated inlet heat exchanger for vaporizing or heating sample streams.

HPR-2 Series Electrically Heated Regulators

The HPR-2 Series Heated Pressure 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.

The modular design of the HPR-2 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 a heat exchange element. The heat exchange element uses GO’s unique spiral wrapped screen as the heat exchange surface. This screen has up to 100 square inches of heat transfer area and careful design forces all sample flow to pass through the element.

The HPR-2 Series of vaporizing pressure reducing regulators enjoy both CSA and KEMA (Cenelec) approvals. 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. Safety considerations can be further enhanced by using the optional TCO (Thermal Cut Out) heater cartridge and proportional controller. These features enable the unit to boast a T3 rating with 150 watts of power!
