Your new Aquarius
D.I. Water Heating System is engineered to offer a safe, reliable,
and effective solution to de-ionized heating needs by providing at temperature ultra-
pure D.I. water. These systems are designed to reduce water usage as well as
maintain high purity requirements. This has been achieved using our patented
HEATEFLEX
heaters and Power-to-Flow
Control system.
Heateflex’s patented Power-to-Flow
Control system eliminates undesirable
overshoots or drops in temperature, which are commonly the result of inadequate PID
temperature controllers. The Aquarius
D.I. Water Heating Systems are designed to
maintain accurate user-specified temperature even with process flow rate variations
and during recirculation (Systems equipped the recirculation option only). The Power-
to-Flow
Control system compensates for changes in the process flow rate by
measuring the flow rate of the fluid as it enters the heaters, measuring the temperature
at various stages in the heating process, and adjusting the proportion of power applied
to each heating zone based on those measurements. This integrated control method
is advancement to previous methods of temperature control that reacts quickly and
robustly to any variations in flow, providing a steady supply of ultra-pure D.I. water at
a stable temperature.
High purity is maintained throughout the heating process due to the use of PVDF, FEP,
and PFA wetted surfaces. The Aquarius
D.I. Water Heating Systems are equipped
with many safeties and components such as thermocouples, a liquid level sensor, a
flow sensor, a pressure transducer, high limit sensors, and thermal cut-off sensors to
protect the heater modules from unnecessary damage due to overheating. All
Aquarius
D.I. Water Heating Systems come standard with a pressure by-pass protect
against over pressurization of the unit. Shorted SCR sensing has been incorporated
in the Aquarius
for added heater protection. A Safety Relay, Safety PLC and GFCI
are standard on the Aquarius
which provides added protection to the unit and for
operators. To monitor the purity level of the exiting heated D.I. water, a resistivity
sensor is available as an option on the Aquarius
D.I. Water Heating Systems. The
Power-to-Flow
Control system also incorporates the use of a visual touch screen user
interface which is straightforward and easy to operate with only a few adjustments
needed after initial settings are entered.
Our Aquarius
systems satisfy all CE and SEMI'S Safety Standards and they are
equipped with safety devices to protect the users as well as the products that they are
processing. These safety devices include
