The Julabo range of Presto temperature control systems includes the air-cooled A30 and A40 and the water-cooled W40. The units have been specifically designed for highly precise, temperature control applications as well as rapid temperature changes, making them suitable for reactor vessels, material stress tests or temperature simulations.

The range features large heating (2.8 kW) and cooling (1.2 kW) capacities and a wide working temperature range of -40 to +250°C (only requires one bath fluid for the entire working temperature range). These systems are capable of compensating for exothermic and endothermic reactions and work reliably even in ambient temperatures up to +40°C.

Magnetically coupled pumps in the Presto units are powerful and maintenance free. Laboratory 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 L/min. The A40 and W40 have more powerful pumps with pressure up to 1.7 bar and a flow rate as high as 40 L/min. The operator can adjust pump capacity by selecting one of five 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. Once in operation, the units are quiet.

The integrated 5.7 industrial grade touch screen provides users with a clear and well-organised view of important information while improving user friendliness. Fingertip control via the touch screen makes the unit easy to operate.

The Prestos have closed side panels without ventilation slits, thereby reducing the overall footprint. A retractable handle and integrated rollers make it easy for one person to move the device.
