Description Pressure sentinels are support heater units designed to transfer technical gases from their liquid to gaseous state. Primarily used to maintain or increase the pressure in a storage vessel or closed loop process, VPB's angular design enables the differential pressure between the vapour and liquid columns to drive the system without the use of an external pump. VPB vaporizers are available in both direct and indirect contact arrangements using select materials to suit the fluid at handAll VPB units are insulated and are available in various configurations to suit the technical gas application.

Direct contact :  Ammonia (NH3)  Carbon dioxide (CO2)  Sulphur hexafluoride (SF6)

Indirect contact :  Chlorine (Cl2)  Nitrous oxide (N2O)  Liquified petroleum gases (LPG)
