INTRODUCTION (CONTINUED):
Performance Data:
The SHC series inline heaters are designed to be used in either single pass or multi-pass
(recirculating) flow applications. An application is defined as single pass when the solution will
enter the heating chamber only once and must be heated to the desired temperature when it
exits the heater. A multi-pass application is one in which the solution will be recirculated
through the process and returned to the chamber heater, and may take several cycles through
the heater to reach the desired temperature.
Single Pass Flow Application:
For single pass applications, the SHC heater is designed to provide a specified temperature
increase at a given flow rate. Table 1 shows the theoretical maximum temperature increase
(∆T) that can be achieved for continuous flow conditions from an 1400 Watt heater.
Note: Maximum operating temperature is 80°C. Values based on the specific heat/weight of
water.
