Fouling factor
Performance tables are based on water with a fouling factor of

per ARI 550/590-98. As fouling increases,
performance decreases. For performance at other than 0.0001 (0.0176) fouling factor see Table 3.
Foreign matter in the chilled water system will adversely affect the heat transfer capability of the
evaporator, and could increase the pressure drop and reduce the water flow. To ensure optimum unit
operation, maintain proper water treatment.
