OPERATION

4.1
GENERAL
Ensure that all heater interlock and safety devices are functional prior to
operation (refer to Section 2, Safety Requirements).
The ID heater is designed to heat DI water in either single pass (trim) or
recirculation applications up to 100°C (minimum flow of 2lpm for IDA
configuration). Figure 4-1 shows approximate flow capacity versus temperature
rise per fluid pass of water.
Water should maintain at least 2 lpm (.53 gpm) of flow and .10 MPa (15 psig) of
pressure to prevent boiling of the fluid near the element.
WARNING: Heater is capable of supplying liquids beyond 200°C. Safety
precautions should be taken (refer to Section 2, Safety Requirements).
