STEAM BOILER FEEDWATER QUALITY

INS 61301607027 Rev A US
For optimum results, the feedwater supply should be tested prior to initial
startup. If the mineral content exceeds the following recommended limits,
various external treatment processes (water softener, RO, etc.) may be
used to correct the problem. Routine manual blow-down or automatic
blow-down option lowers concentrations of impurities and maintains the
pH level above 7.0.
Feedwater quality:
• Hardness: 0.5 to 5.0 grains/gallon (8 to 85 ppm)
• Resistivity: Not to exceed 50 Kohms/cm
• Temperature: 100°F to 150°F (38°C to 65°C)
• pH: 6.8 to 7.5
An analysis of the on-site boiler feedwater should be made by a recognized
and reliable water treatment company to ascertain the existing condition
and treatment required.
Reverse osmosis (RO) water treatment systems of various capacities may
be purchased from Getinge. The Model HS-300 Water Treatment System
(Figure 7–3) meets the requirements of one 633HC Steam Sterilizer. For
installations where one water treatment system will supply multiple
sterilizers, consult your Getinge representative.
