TYTANu DI Water Heater

1.2 Performance Data:
The TYTANu DI Water Heater is designed for inline heating of DI water. It will perform both as a recirculating heater, and as a
one-pass heater. The TYTANu DI Water Heater is designed to provide a specified temperature increase at a given flow rate.
Table 1 shows the maximum temperature increase (∆T) that can be achieved for continuous flow conditions at the specific
heater power ratings varying from 24kW to 144 kW (Higher wattage systems available upon request). The temperature control
system provided with the heater will modulate the power to the heating columns in order to maintain your specific outlet
temperature setting.

1.3 Safety Network:
The TYTANu DI Water Heater is protected from accidental damage or unsafe operating conditions with a network of safety
interlocks. The safety interlocks will disengage power to the heaters until power is manually restored at the control. The safety
interlocks offered on the TYTANu DI Water Heater are listed below.
Bi-Metallic Heater Over-Temperature Sensor:
The temperature of the heating elements is continuously monitored by these bimetallic sensors. Any over-temperature situation
will cause the main load contactor to disengage, and sound the audible alarm. This will require a manual reset of the heater
once the overheat event has been corrected. The over temperature sensors are provided with a fixed setting of 262°F (128°C).
(Maximum Element Surface Temperature)
High Temperature Alarm:
The High Temperature Alarm setting on the OMRON E5CK is factory set at 248°F (120°C). If this temperature is detected at the
process sensor. the controller will disengage the main load contactor and sound the audible alarm. This will require a manual
reset of the heater once the overheat event has been corrected.
Over-Temperature Controller:
This over-temperature controller is a separate controller mounted inside the control enclosure. It uses a separate temperature
sensor to monitor the hot-zone temperature in one of the heating columns.
This over-temperature controller has two different settings:
1. Over-temperature cutoff (SP2). This setting needs to be adjusted manually by the customer, to be set 18°F
(10°C) higher than the set point of the Omron Temperature controller. This setting will cutoff power to the heaters
if the internal temperature rises above this value, but will automatically re-engage the heaters when the
temperature drops below this value. This is not an alarm set point.
