DOMESTIC DISTRIBUTION OF GAS

CUSTOMER CHALLENGE

In domestic distribution of gas, it is required that the output pressure remains constant for a period if the power to the unit fails or is cut.  If during a power failure the gas lines fail to zero, the start up of these lines is extremely costly with the re-purging/cleaning of the lines before the system can be restarted.

NORGREN SOLUTION

The type 422 failfreeze IP electronic converter has unique characteristics in a stand-alone package, in that the output pressure remains constant for a set period if the power to the unit fails or is cut.

The time that the unit keeps the pressure at a constant level has proved critical to the customer in getting the distribution of gas to homes back to normal in as quick a time and as efficiently as possible.

These units are typically also used in damper valves and cooling systems to ensure that the pressure and so coolant remains constant even if a failure occurs to the power system, which in thermal power plants is critical.
