Supply water
The quality of the water supplied to the intensifier has a direct effect on the life of the intensifier and
the consumables. Bad water quality increases operating costs by causing unnecessary wear on
pump parts and shortening maintenance intervals. Mineral deposits can clog the cooling fins in the
heat exchanger.
Softened water is necessary for most systems. Get advice from a specialist for recommendations
for choosing a water treatment system. Reverse osmosis systems are available from Hypertherm.
Water quality
Refer to Test the water quality on page 93.
Water temperature
If the cooling water or the supply water temperature is higher than 24°C (75°F), cool the water
before use. Water that is too warm can shorten high-pressure seal life.
Compressed air
Air pressure that is too low can prevent the bleed-down valve from closing and can cause the
intensifier to overstroke.
Air pressure that is too high can cause damage to the needle and the seat in the bleed-down valve.
