Equally, de-ionized water should not be used as the load coolant.
De-ionization allows the removal of particles as small as ions from
a solution and is used to purify water and remove salts and other
impurities. However, since this water is ion-starved, it will chemically
attack the brass, copper and aluminum found in the water
system and re-deposit some of the metals on the resistor. As a
result, the load will overheat and fail rapidly. |

Distilled water is water which has been heated to the boiling point
so that impurities are separated from the water, which becomes
vapor or steam at 212ï F (100ï C). The steam is then cooled and
condensed back into pure liquid form. The impurities remain as
residue in the steam kettle. This distillation system removes
organic and inorganic chemicals, heavy metals, volatile gasses,
and other contaminants. Distilled water used as the coolant will
yield the maximum life expectancy of the load and is the best
solution if water quality is in question. Softened or de-mineralized
water is also acceptable due to the lower amount of dissolved
solids present |
