Pryco’s Sub-base Tanks are designed specifically for generator set mounting.  The physical
size of each depends upon the foot print of the gen set and required capacity.  Sub-base Tanks
are available in a
Basic or a Custom design.   

  • Basic Sub-base tanks will always have a closed-top, double wall Secondary
    Containment area.   This group of tanks may be U/L Listed if it constructed within the
    U/L Listing requirements of U/L Label #142, File #MH17469.  A Basic sub-base tank
    may be fitted with any options except a 200% rupture basin or any option that would
    violate the provisions of the U/L label cite above.  

  • Custom Sub-base tanks may be of single-wall construction or be designed with a
    Secondary Containment area (an open-top Rupture Basin or a  Double Wall).  These
    tanks may also be U/L Listed as above if the design fits within the U/L Label provisions.  
    A Custom sub-base tank  may be fitted with any options including a 200% rupture basin
    except any that would violate the provisions of its U/L label.

All sub-base tanks comply with NFPA 30, Flammable and Combustible Liquids Code and
NFPA 110, Standard or Emergency and Standby Power Systems.  When the secondary
container “double wall”  is added, the tank also complies with NFPA 37 - Standard for
Installation and Use of Stationary Combustible Engine and Gas Turbine.

Since Sub-base tanks differ depending upon factors such as gen-set model, capacity (number
of gallons), and any physical limitation you might have, please ...

This is a Basic 75 gallon, U/L Listed, double walled, sub-base tank with a stub-up area.  
It is on its side to get a better view of connection ports.  The two rails running the length
are mounting rails (Option 533) for gen-sets not as wide as the sub-base tank.  Also
shown at the end of the tank extending into the double wall area (inside the stub-up area)
, is a secondary containment leak detector (Option 509RB).
This is a Custom Single Wall Sub-base Tank with vent and fill caps in place.  The
square enclosure is where level sensors are located.  The sensors my be for high and
low level alarms and switches.  Four lift lugs are located at each corner.  Also seen here
are support brackets located at each gen-set mounting point.  These support brackets
are within the secondary containment area of a double wall sub-base tank.
