    KSI

    Description

    The KSI gas heat exchanger by Pietro Fiorentini is designed to preheat gas upstream of pressure regulation systems, counteracting temperature drops caused by the Joule–Thomson effect.
    Featuring a vertical shell-and-tube design, it is suitable for natural gas, air, propane and other non-aggressive gases, using hot water, superheated water or steam as heating medium.

    Optional accessories include pressure gauges, pressure switches, safety valves and an air self-venting device.
