The WaterWizard automatically, internally, and without a single moving part, subcools its own condensate in a 2-pass vertical cross-flow heat exchange configuration. Saturated steam pressures up to 125 PSIG are suitable for use with the WaterWizard WITHOUT pressure reducing stations. No condensate traps (the unit is supplied standard with a drilled orifice) are required with cold water inlet temperatures below 110 degrees F.
