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.
Certified Quality Assurance - ASME Section VIII designed pressure vessels and piping designed per ASME B31.3
Three-valve block and bypass piping for dryer isolation
Ease of Service & Superior Corrosion Resistance - Removable stainless steel diffusers
Downflow Drying - eliminates fluidization to extend desiccant life
No Gas Lost to Purge - closed loop convection regeneration
Energy Savings & Complete Diagnostics - microprocessor based
Safe, Reliable & Dependable Operation -
- Electrical Enclosures for Class 1, Division 2, Group C and D classifications (Optional Class 1, Division 1)
- Heater Element and Over-Temperature Shutdowns
- Blower and Heater Interlocks
Air-cooled heat exchanger with TEFC fan motor, non-sparking fan blades, fan cycling control
Complete Purification System - Factory mounted and piped coalescing 0.0014 ppmw oil & aerosol removal prefilter and 0.9m absolute particulate removal afterfilter
Moisture separator and condensate collection vessel
Heavy-Duty blower ensures reliable operation
Incoloy sheathed, low watt density heater and insulated heater housing, dual set point temperature controller for monitoring and over-temperature protection
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.
