Key Applications

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.
