TEMPERATURE CONTROL UNITS
SINGLE FLUID HEATING & COOLING SYSTEMS


      The Thermal Fluid Engineering Division of GMM Pfaudler Ltd., the world's leading manufacturer of glassed-steel vessels has developed a range of innovative and advanced single fluid temperature controls loops for reactor heating and cooling.


      Working at the leading edge of thermal fluid technology, these systems are designed to be affordable, self contained, compact units, which incorporate all the essential functions of the heating and cooling process.


      Single fluid heating and cooling systems operate with only one heat transfer fluid circulating through out the reactor jacket. The temperature of the fluid, and therefore the reactor temperature, are adjusted for heating or cooling by external means. Often in the case of heating, this would be steam or via electric elements. In the case of cooling, this could be cooling water, glycol, and for our advance heater/chiller units, mechanical refrigeration.


      The modular design of the systems means that GMM Pfaudler engineers can propose an individually designed solution to meet the requirements of even the most complicated processes in your project. This also minimises installation time and cost and provides a factory-tested system.


Advantages of Temperature Control Unit in Reactor Operations:
Accurate temperature control to +/- 1º C without risk to your reactor.
Rapid heating and chilling profiles can be designed, reducing batch times.
Reapitability and accurate recordable measurement for meeting FDA requiremets.
Programmable heating and cooling ramps for accurate unsupervised operation.
No switiching between jacket service fulids, preventing cross-contamination, corrosion or thermal shocks to the vessel.
Smooth, continuous temperature control, with no gaps because there is no fluid changeovers.
No interruption of process and no hot spots, resulting in higher product yields and quality. Off-batches are minimized, if not eliminated.
Savings on expensive raw materials can be made because the yield is maximized without adding excess reactions.
Suitable for the very cold operating temperatures required by today's new chemical formulae and reactions.
Fully automatic capability, hence less manpower required.
