Water Quality Settings on the DewPoint Machine
It is critical that water quality settings in the DewPoint control system are set up correctly. Failure to do so may
result in poor water quality conditions in the boiler. Poor boiler water quality can cause water carry-over into
hay during the baling process, which will damage the hay and may create a risk of stack fires.
● Obtain water test and recommendations report for your operation.
□ Your water samples should have been processed and the report should be available from your
dealer
● ENTER water quality settings based on water test and recommendations report
Water Quality/Blowdown Principles
● Boiler Blowdown
□ Boiler water quality maintenance is critical in maintaining the health and longevity of your boiler
system. Proper blowdown settings and procedures are a critical element in maintaining boiler water
quality
□ Blowdown frequency and volume
• Frequency of blowdown is dependent upon your water quality test
• Water tests prior to the use of the DewPoint machine provide the information you need to
enter in the water quality screen for an appropriate blowdown schedule.
• If you notice water carryover or “foaming” during field operation you should check your supply
water source to be sure your water treatment is working properly. You may also need change
the settings in the water quality screen.
• “Foaming” or water “carry-over” occurs because of high surface tension on the surface of the
boiler water. It is the same reaction that occurs when a pan of spaghetti noodles cooking on the
stove boils over. Surface tension is increased because of high concentrations of contaminants
left behind in the boiler water as steam is produced and discharged from the boiler during field
operation.
• The blowdown process removes some of the contaminated water in a controlled manner and
allows new clean supply water to replace the old.
