The Cyclonic Distributor System™ (CDS) is an innovative vessel technology providing higher flow rates, less pressure loss, improved treatment capacity, product flexibility, and water conservation. Simply put—Smart technology. The CDS creates uniform water distribution in both service and regeneration flow paths to better utilize media surface area and depth, which extends the contaminant removal capacity of the media and subsequently requires less regeneration. Mid plates are available to compartmentalize several different media in a single vessel—eliminating the need for multiple tank systems, reducing system costs, and providing easier installations and servicability. |

BENEFITS |
• |
Conserves water |
• |
Softeners require less salt |
• |
30% less backwashing |
• |
Increased resin capacity of 10 to 15% compared to standard basket distribution systems |
• |
Up to 40% less pressure drop through the system |
• |
Spin-welded plate to inner bottom dome designed to handle over 6500 lbs. of force and differential pressure |
• |
No gravel underbed saves on overall cost and unit weight |
• |
Permanent attachment of the riser tube and distribution plates eliminates rebedding when servicing the valve |
• |
100% corrosion-free |

|
|
Standard Service
leaves "dead zones" of
unused media in the
bed and promotes
channeling. |
|
Cyclonic Service
utilizes the entire
media bed. |
|
Standard Backwash
lifts the bed. |
|
Cyclonic Backwash
utilizes angled plate
slots to expand the
full bed and swirl
the media, resulting in
a more vigorous and
effective cleaning of
the entire media bed. |

CDS VS. STANDARD BASKET DISTRIBUTORS |
(Comparing tanks with one cubic foot of 10 percent resin.) |
CDS Tank |
Standard Tank |
Bed expansion in backwash 10.5 inches of lift |
Bed expansion in backwash 5 inches of lift |
Time to lift bed to full expansion
at 2.0 gpm = 2.0 minutes |
Time to lift bed to full expansion
at 2.0 gpm = 4.25 minutes |
Four minute backwash time = 8.0 gal. |
Eight minute backwash time = 16.0 gal. |
Fast rinse reduced from six to two minutes
at 2.0 gpm = 4.0 gal. |
Fast rinse had to stay at six minutes
at 2.0 gpm = 12.0 gal. |
|
|
BACKWASH TESTING RESULTS OF A 16x65 CDS CARBON SYSTEM |
"Sweet Spot" for backwash is 5.76 gpm/sq.ft. |
Standard specification is 8 to 10 gpm. |
Volume savings and fluidization time with full expansion of bed is less than 2 minutes. |
CDS backwashes for 7 to 8 minutes (compared to typical carbon filters of 14 minutes or more). |

TANK WARRANTY:
Residential polypropylene-lined pressure vessels (up to 13 inch diameter) are warranted to be free of manufacturing and material defects for a period of 10 years if operated within specifications in residential water treatment applications.

VACUUM PROTECTION & FLEX CONNECTORS |
Fiberglass/composite pressure vessels are rated for an internal negative pressure of 5-inches Hg (17 Pa) vacuum below atmospheric. If negative pressure could ever exceed 5-inches Hg (17 Pa), an adequate vacuum breaker must be installed between the pressure vessel inlet and any valves (see illustration right). For enclosed tank applications, the vacuum breaker should be installed at the highest location in the system plumbing.
System connections to the pressure vessel must accomodate vertical expansion between side, top, and bottom openings. Either flexibility in piping or flex connectors, as shown here, are recommended. |
