INTRODUCTION (Continued):
While the DAC control system is capable of providing an outlet temperature within 0.3°C
of the desired PROCESS SETPOINT, the maximum possible temperature rise through
the heater is dependant upon the wattage of the unit and the water flow rate through the
unit. The following table illustrates the maximum temperature rise of various models
based upon the water flow rate through the unit.
