  • COKE PETROLEUM CALCINED RS-3 LORESCO - 50 LB BAG (68#/CUFT) IMPRESSED CURRENT BACKFILL

    RS-3®, due to its maufacturing process, is simple to install by either mixing and pumping or by pouring dry. With deep anode systems, pumping from the bottom up is recommended. RS-3® has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of super heavy mud. Time before energizing is greatly reduced after installing RS-3®. The modified surface of the carbon particles coupled with the action of the surfactants in RS-3® will achieve positive electrical contact by settling.Vibrating or compacting is not necessary. See installation section on cd or in the catalog for additional pumping data.

    Material Description:
    Loresco RS-3® is a surface modified, blended, and sized carbon backfill with surfactants.

    Specifications:

    • Bulk Density: 68 lbs. per cubic foot
    • All particles shaped and surface modified for maximum electrical conductivity and high-current applications
    • Particle sized to facilitate pumping and pouring applications with rapid settling
    • Maximum particle size 2.5mm
    • Minimum calcination temperature of base materials is 1250° C
    • Base materials are calcined under ISO 9002:2000 quality control
    • No de-dusting oils are used during the manufacture of base particles

    Shipping Data:
    Loresco RS-3® is shipped in fifty (50) pound (22.7 kg) coated, woven polypropylene bags. RS-3® may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fifty bags per pallet. Proven export packaging is also available.

  • COKE PETROLEUM CALCINED DW-1 LORESCO - 2000 LB BAG IMPRESSED CURRENT BACKFILL

    • Loresco DW-1® may be poured freely into dry applications. Tamping is not required. When it is applied by pumping, the recommended method is to pump from the bottom of the bored hole upward. After the application pipe (a one-inch steel pipe) is lowered down to the bottom of the bored hole, it is coupled to a 20 GPM pump with a minimum capacity of 250 psi. Normally, the application pipe does not have to be raised during pumping procedures.

    Horizontal Installation Procedure:

    • Have a reasonably clean ditch (design usually calls for a ditch one foot wide).
    • Pour Loresco DW-1® in a continuous layer six inches deep (or as specified).
    • Place anodes on top of DW-1®.
    • Pour DW-1® in a continuous layer six inches deep until anodes are covered by a six inch backfill cover (or as specified).
    • Fill the remainder of the ditch as specified.

    Vertical Installation Procedure

    • Have a reasonably clean hole (depth depending on soil resistivity).
    • Place one foot of DW-1® in bottom of hole.
    • Lower and center anode in proper position.
    • Pour DW-1® over anode until design level is reached.
    • Fill remainder of hole as design specifies.

    Specifications:

    • Bulk density: 74 lbs. per cubic foot.
    • Particle sizing ranging from 0.1 to 1 mm.

    Shipping Data:

    • Loresco DW-1® is shipped in fifty (50) pound (22.7 kg) coated, woven polypropylene bags. DW-1® may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fifty bags per pallet. Proven export packaging is also available.

  • COKE PETROLEUM CALCINED SC-3 LORESCO - 50 LB BAG (74#/cuft) IMPRESSED CURRRENT BACKFILL

    Loresco SC-3®, due to its dust-free manufacture, is simple to install by either mixing and pumping or by pouring. With deep anode systems, pumping from the bottom up is recommended. Loresco SC-3® has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of heavy mud. A recommended mix is seven gallons of water per one hundred pounds. After installing SC-3®, allow twenty-four hours settling time before energizing. The modified surface of the carbon particles coupled with the action of the surfactants in SC-3® will achieve positive electrical contact by settling. Vibrating or compacting is not necessary.

    Material Description:

    Loresco SC-3® is a surface modified, blended, and sized carbon backfill with surfactants.

    Specifications:

    • Bulk Density: 74 lbs. per cubic foot
    • Predominantly round particles
    • All particles surface modified for maximum electrical conductivity

    • Minimum calcination temperature of base materials is 1250° C
    • Base materials are calcined under ISO 9002 quality control
    • Surfactants are added to assist pumping and settling
    • No de-dusting oils are used during the manufacture of base particles
