Electric heat exchangers for natural gas (CNG)

scambiatore CNG -heat-exchanger CNG
scambiatore CNG-heat-exchanger-CNG 2


Traditional systems provide the water preheating by hot water producing unit: our solution provide an electric resistance already assembled on board that preheat the water in the vessel of the heat exchanger.

Our solution excludes external hot water producing unit as thermal plants, boilers and circulating pumps. This solution reduces drastically installation and maintenance costs.

Our range provides heat exchangers with Max. Design Pressure of 250 bar. These equipments are suitable to preheat the gas compressed (CNG) on trailers and CNG must be preheated before to be reduced.

We have many installations in Italy, Bulgaria and Vietnam.

These devices are designed and produced in accordance to 2014/68/UE PED Pressure Equipment Directive.
