Julabo PRESTO W58x highly dynamic temperature control system
The most powerful, 1-stage, highly dynamic temperature control systems
The water-cooled PRESTO W58x can temperature control applications with high performance requirements very quickly and efficiently.
It has a very high cooling capacity of 33 kW at 20 °C and therefore offers large power reserves across the entire operating temperature range, particularly at temperatures between -30 °C and -40 °C, as is often required in the automotive testing sector.
The PRESTO W58x process thermostat is equipped with a gear pump.
This means that even highly viscous media such as water-glycol mixtures can be used at low temperatures of down to -45 °C.
The magnetically coupled pump allows the user to optimise the pump performance to the application, even over long distances and heights and for pressure-sensitive applications.
Thanks to the use of the latest thermodynamic technologies, the cooling capacity is automatically adapted to the current power requirement.
In conjunction with other optimisations, the PRESTO W58x is very economical and energy-efficient.

* Performance data measured in accordance with DIN 12876. Cooling capacities up to 20 °C measured with ethanol, above 20 °C measured with thermal oil, unless otherwise specified. Performance data apply at an ambient temperature of 20 °C. Performance values may deviate with other temperature control fluids.
** The cooling water consumption outside the recommended cooling water properties may deviate.
*** At cooling water temperatures of 25 °C and higher, the minimum differential pressure is 1 bar
