Thermodynamic Power

The new PRESTO^® from JULABO represents the state-of-the-art for modern laboratories. The first models in this redesigned line of temperature-control instruments are the air-cooled A30 and A40 as well as the water-cooled W40. These instruments cover a working temperature range of -40 to +250 °C with 1.2 kW of cooling capacity and 2.8 kW of heating capacity. Maximum heating capacity can also be adapted to fluctuations in the mains power supply. Highly efficient components give these instruments the ability to compensate for exothermic and endothermic reactions with extraordinary speed. The new PRESTO® units are extremely robust and work reliably even if the ambient temperature climbs as high as +40 °C.

Magnetically-coupled pumps in the PRESTO^® units are powerful and maintenance-free. Lab users benefit from high flow rates, constant pressure, and a controlled build-up of pump pressure. The pump in the A30 has a rated pressure of 0.5 bar and a maximum flow rate of 20 Lpm. The A40 and W40 have more powerful pumps with pressure up to 1.7 bar and a flow rate as high as 40 Lpm. The operator can adjust pump capacity by selecting one of four stages or by entering a specific pressure. The closed pumping loop isolates the heat transfer liquid from ambient air, preventing penetration of moisture and oxidation.

The integrated 5.7-inch industrial-grade touch panel is one of the identifying characteristics of the new PRESTO^®. It gives the user a clear and well-organized view of important information while greatly improving user-friendliness. Fingertip control via the new touchscreen makes it incredibly easy to operate the new PRESTO^® units.

Password management for one administrator and up to two additional levels of authorization makes it easier to manage laboratory procedures.

For example, the new PRESTO^® units use one and the same heat transfer liquid across the entire working temperature range. The filling opening for the liquid is easily accessible on the top side of the unit.

Once in operation, the new PRESTO^® units are whisper quiet and barely audible in a laboratory. Like all JULABO instruments, the new PRESTOs^® have closed side panels without ventilation slits. This reduces to a minimum the amount of space needed to operate the units because any other lab instruments may be placed directly next to the PRESTO^®.

Multiple interfaces permit remote control of the PRESTO® across networks and in superordinated control systems. The integrated Ethernet interface provides complete access to all of PRESTO^®’s operating functions.

Yet another control option is the USB interface, a first in dynamic temperature control systems. When combined with the proven JULABO WirelessTEMP solution, it permits completely wireless control of the instrument.
