  • Amount of water sprayed from truck mount tm3447dc

    Dear Donald,
    We have TM3447DC with Kohler Engine.
    When the machine is set up for Carpet Cleaning;
    (1.000 psi and 2 Gph chemical flow)
    1) What ratio is the water added to the chemical?
    In other word, while we get 2 gallons of chemical per hour, HOW MANY GALLONS OF WATER IS ADDED TO IT? How much ratio of water is added to it?

    The reason for this question is;
    Many of the cleaning chemicals requires 15 times more chemicals for the truck mount equipment comparing to the portable equipment with flow meter at 2 gph (written on it) This gave us an idea that truck mount equipment is adding 15 times more water to the chemical.
    BUT
    When we tested and sprayed with:
    15" (5 jets) wand at 1.000 psi with 2 gph flow we've got:
    7,5 lt (2 gal) in 1 minute time = 450 lt (119 gal) per hour.
    Which means; 442,5 lt (117 gal) of it is water and 7,5 lt (2 gal) of it is the chemical. In this case we are getting 59 times more water for the chemical.
    12" (4 jets) wand at 1.000 psi with 2 gph flow we've got:
    6 lt (1,5 gal) in 1 minute time = 360 lt (95 gal) per hour.
    Which means; 352,5 lt (93 gal) of it is water and 7,5 lt (2 gal) of it is the chemical. In this case we are getting 47 times more water for the chemical.

    All those does not match the standards written on the chemicals like; shazaam kryptonium (1 oz for portable versus 32 oz for truck mount) which is 15 times more for the truck mount, but the machine sprays 59 times (15" wand) 47 times for (12" wand). Also same goes for shazaam flush ultra rinse aide chemical.

    Other questions in addition to the above;
    2) How can we reduce the AMOUNT of water sprayed while at 1.000 psi and 2 gph flow?
    3) What amount are the jet sprays are adjusted to spray normally?

    Metering in formulated rinse aid

    Step one, determine the orifice size of the jet you are using.
    Example two jet wand X 02 jets = total 04 opening.
    If I am cleaning at 500 psi, my machine will spray 1.41 gallon in one minute or 84.60 gallons per hour.
    If my flow meter was set to 2 gpm then I am at 2 gallons of injected product and 82.60 gallons of water.
    OR a 1 to 41.3 ratio.
    Normally all presprays are injected with an injection sprayer.
    Example
    http://www.steam-brite.com/advanced_...ection+sprayer
    Only the formulated rinse aid is injected into the truckmount during the rinsing of the carpet.
    Typically a quart of rinse aid is added to 4.75 gallons of water. This in turn is metered into the truckmount at 1 to 41.

    As a side note the last number on a jet refers to the gallon per minute flow at 4000 psi. See chart.
