Gas heaters (PG series)

Application and design of PG gas heaters


PG gas heaters
that are manufactured by BatysMunaiGazZhabdyktary, LLP can be installed in gas supply facilities both indoors and outdoors. For outdoors operation the gas heater is insulated from environment by a metal heated shell. ThePG gas heaters are designed to warm natural gas without any aggressive foreign materials to the set temperature. Gas is warmed up by coolant (a low-freezing liquid) or by a treated water from an external source.

A simple structure of the gas heater manufactured by BatysMunaiGazZhabdyrkary, LLP decreases operation costs and increases service life. The heater structure is shell and tube heat exchangers with U-shape tube bundle. The tube bundle is produced from stainless steel. This tube bundle is tested both separately and in assembly with the gas heater.
