Chiller/Heater Performance Data
This manual uses a typical 120-ton water-cooled chiller/
heater consisting of four modules with brazed plate heat
exchangers and condensers for example purposes. (See
Table below) The model number and a chiller/heater’s
precise configuration can be found on the model
nameplate. See Figure 1, p. 7.
