Request Information
The heart of the LNG Vaporizer Assembly is the well-known HPR-2 Series heated pressure control valve. This unit has been used in many successful applications requiring heating of a process stream sample prior to analysis to prevent freeze up or for vaporization. The HPR-2 is a modularized unit consisting of a heated section and pressure control section. A field demonstration has now shown this vaporizer assembly to be serviceable in the vaporization of LNG product for analytical purposes and that homogeneous samples can be obtained under steady state operating conditions.

The HPR-2 pressure control valve is contained in a painted, insulated sheet metal enclosure and combined with an insulated input line plus a pressure gauge and relief valve. The heater section of the electric version is equipped with a thermostat for temperature control and is constructed to meet standard Division 1 Electrical Code requirements.

Note

Note

 N/A
  1. Contact the factory for any additional requirements.
  2. Units that will be used for flammable liquid or gas with fire point at 200ºC or below require the TCO Thermistor. It is also recommended to use the 1-PC body option. In addition, Tefzel® and PCTFE seats in these units are recommended to use the captured vent cap option which provides for venting to a safe location.
