What are Ratiometric Formulas? Ratiometric Formulas are simply formulas that can process different sized loads in the same washer with the same chemical processes. This is done by varying the reactants (water and chemical) to the size of the load. The scientific term for this is stoichiometry. If the water and chemicals are varied with the load size, the same chemical process should be carried out without regard to the size of the load.

Many customers ask "What is needed to do Ratiometric Formulas? Do I need an automatic chemical system?". To implement a Ratiometric formula on a MicroPulse based washing machine, all that is required is a water meter to measure the water and a method for obtaining the weight of the load (automatically or prompted from keypad). An automatic chemical system is not required to do Ratiometric formulas as the MicroPulse can even prompt the operator to add the adjusted amount of chemical manually.

Many customers also ask "Do I need the Softrol Catalyst Chemical System to receive the full benefit of the Ratiometric Formulas available on the MicroPulse?". The answer is no. As stated above, no chemical system is required at all. As long as the chemicals can be administered accurately by the operator when prompted, the full benefit of Ratiometric Formulas will be realized.

However, one must have a Softrol Catalyst Chemical System to receive the full benefits of a Softrol Catalyst Chemical System!

Many chemical suppliers ask "Can we implement Ratiometric formulas using our chemical feed systems? ". The answer is yes. If chemical pumps or other devices are wired to the chemical outputs of a MicroPulse based washer, the duration of the outputs will be varied according to the formula thus automatically adjusting the quantity of chemical added to the machine.

In the next article we will cover how to actually create Ratiometric formulas with some examples. In the mean time, please review the features discussed in the article Add 0 oz. pH 7.0 Buffer:
