The Hydroheater®
is a sophisticated heat transfer device capable of 100% heat transfer
efficiency and precise temperature control. It's rugged design will
provide day-in and day-out operation without scaling, fouling or plugging.
A basic understanding of the Hydroheater and its operation characteristics
will ensure a successful application and complete users satisfaction.
The Hydroheater®
works by injecting precise amounts of steam at a high velocity into
your process fluids, slurries or products. The steam changes the
liquid into very tiny bubbles creating the ideal surface area needed
for rapid and efficient heat transfer. This provides for
instantaneous transfer of heat from steam to the liquid. This rapid
heat transfer that occurs in the Hydroheater causes the steam to
condense and be dispersed into the liquid very quickly, eliminating
the hammer and vibration associated with less sophisticated heaters.
The Hydroheater® employs a unique
internal geometry to control the steam injection process. A variable
area nozzle/stem plug is used to precisely regulate the steam flow.
A movable combining tube offers an adjustable steam condensing region
which maintains hammer free operation as well as providing additional
control of liquid pressure control. Direct
steam injection provides instant heat and precise temperature control
to product and process while at the same time eliminating noise,
vibration, hammer, downtime and high energy costs often associated
with other heat transfer devices.

 Because the Hydroheater injects steam directly into the process liquid, the total heating capacity of the steam, both latent and sensible, is utilized, yielding 100% heat transfer efficiency. Indirect methods of heat transfer (Heat Exchangers) utilize only the latent heat of the steam and can be as much as 15-20% less efficient than the Hydroheater in transferring energy from the steam to the liquid. The higher operating efficiency of the Hydroheater means that less steam will be required for the same heating application.
Unlike indirect methods of heating,
the Hydroheater does not have a "heat transfer barrier"
such as the wall separating the steam and the liquid in a
heat exchanger. Heat transfer barriers have a specific rate
of heat conduction that can slow the response time of the
device to process changes. The Hydroheater has no such barrier,
and consequently can respond instantly to signals from the
temperature controller. In effect, there is almost no lag
time in the Hydroheater. The liquid temperature will change
immediately with changes in stem position. As a result, the
Hydroheater will control as fast and precise as the control
loop is capable of measuring and responding to changes in
temperature. |
