GAS PURIFIERS
FSD-T Series twin tower purification systems are completely self-contained, fully automatic, heat-reactivated, closed-loop blower purge desiccant dryers designed to remove water vapor from natural gas.
Using molecular sieve as the drying media, these systems will continuously dry CNG down to an outlet moisture content of 0.5 lbs/MMscf, or lower.Specifically engineered for large flow heavy-duty NGV fleet refueling applications, FSD-T Series Twin Tower systems provide dry CNG 24 hours a day.
