Hydraulically Sealed Systems
Product Details:
Unistats. should not be compared to conventional technology. Thermodynamically there is no alternative. Unistats® embody capacity and dynamics. Small in size, big in power.
The Unistat System combines the efficiencies of effective thermodynamics and modern microelectronics, making it a highly efficient alternative to open bath temperature control technology. Unistats are circulation thermostats without a bath. An expansion vessel for thermal expansion and contraction replaces the conventional bath. The expansion vessel is isolated from the thermoregulation of open baths (F). Being hydraulically sealed they can be located below or above the application. The Unistat principle uses minimal heat transfer fluid (HTF) volume and increased thermal transfer abilities through higher HTF flow rates, reduced HTF pressure and highly efficient heat exchange surfaces. This Increases the systems speed of response to changes in demand. Unistats have the most rapid ramping rates, and are capable of cooling rates of more than 100 K/ hr. For comparisons in cooling power densities (Watt/ litre) please refer to DIN 12876.
