FSD-A Series - Single Tower Natural Gas Dryers

AIR & GAS TREATMENT / DESICCANT COMPRESSED AIR DRYERS

FSD-A Series dryers are designed to efficiently remove water vapor and extraneous contaminants from Compressed Natural Gas. FSD-A Series dryers include a stationary regeneration package for convenience, eliminating rental costs and scheduling delays for third party regeneration.

Certified Quality Assurance - ASME Section VIII designed pressure vessels and piping designed per ASME B31.3

Dryer isolation during regeneration cycle - three-valve block and bypass piping

Optimized footprint provides ease of service

Superior Corrosion Resistance - 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

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

Moisture separator and condensate collection vessel

The FSD-A Series dryers are an economical alternative to twin tower drying systems in CNG vehicular fueling stations. Coalescing and particulate filters are included for, scale, liquid aerosol and desiccant fine removal, further enhancing drying performance and gas quality. Specifically engineered for NGV fleet refueling applications with low to medium flow.
