PRESTO – Highly Dynamic Powerhouses


The PRESTO series is designed for precise temperature control as well as rapid cool-down and heat-up phases, making it ideal for reactor temperature control, material stress tests, or temperature simulations.

PRESTO W91/W92 – High-end Thermo-dynamical Product



PRESTO models W91, W92 as well as W91x and W92x benefit in particular from a significant increase in the refrigeration-heating capacity. The heating capacity increased from previously 12 kW to 18 kW, The W92tt(x) models offer even twice the heating capacity. The cooling capacity also increased considerably for all W92 models, for example, to 25 kW at 20 °C.

Special models PRESTO W92x and PRESTO W92ttx are additionally available with a powerful gear pump.  The magnetic coupling of the pumps ensures a hydraulically sealed cooling circuit avoiding condensation and odors. Using highly efficient components, the models of the PRESTO W91 and W91 series impress as outstanding high-end product with high heating, refrigeration, and pump capacities.

The integrated 5.7-inch color industrial-grade touch panel is one of the identifying characteristics of the PRESTO models. It gives the user a clear and well-organized view of important information while greatly improving user-friendliness through intuitive control with the tip of a finger. The PRESTO ® models are whisper quiet and barely audible in a laboratory. They are extremely robust and work reliably even if the ambient temperature climbs as high as +40 °C. Numerous interfaces permit new remote control possibilities across networks and in superordinate control systems. In the case of a malfunction, an integrated black box enables quick support by the JULABO service team.

Functional and Space Saving

Thanks to free side panels without ventilation slits, the required footprint is reduced to a minimum. The instruments can be installed directly next to each other or the application. The PRESTO systems are available in three voltage variants for flexible usage worldwide.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Demonstration of a single molecule piezoelectric effect

Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
