With a heating performance of up to 2.7 kW and a cooling performance of up to 1.2 kW, these PRESTO systems over an operating temperature range between -40°C and 250°C. The systems are very quiet in operation; thanks to the inte- grated handles and castors, they are easy to move around in the lab. Digital and analog interfaces are included as a standard. 4 PRESTO highly dynamic temperature control systems down to -50°C The PRESTO A45 and W50 are the most powerful PRESTO models with one-stage cold control. The systems combine maximum heating and cooling power with strong pumps. In the extended version A45T and W50t, they even have a heating performance of 12 kW. The pump pressure is adjustable and is indicated at the display. Typical applications in- clude temperature control for double-walled reaction vessels, reactor systems, auto- claves, distillations, pilot systems, semiconductor industry etc. Technical data: Temperature stability: ±0.05 – ±0.1°C External Pt100 sensor connection: yes w e b c o d e WW2KN011 1 PRESTO Highly Dynamic Temperature Control Systems, JULABO An entirely new generation of highly dynamic temperature control systems by JULABO. The new PRESTO ® systems are designed for precise temperature control as well as rap- id temperature changes, making them ideal for reactor vessels, material stress tests, or temperature simulations. These instruments cover a working temperature of -92 to +250°C with high cooling and heating capacity. Highly efficient components give these instru- ments the ability to compensate for exothermic and endothermic reactions with extraor- dinary speed. Permanent internal monitoring and self-lubricating pumps contribute to the new PRESTO ® ’s long service life. The integrated 5.7-inch color 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-friendli- ness. Once in operation, the new PRESTO ® units are whisper quiet and barely audible in a laboratory. The new PRESTO ® units are extremely robust and work reliably even if the ambient temperature climbs as high as +40°C. Multiple interfaces permit remote control of the PRESTO ® across networks and in superordinated control systems. Closed side panels without ventilation slits reduce the required footprint of the devices to a minimum. Benefits and functions: • Operating temperature range from -92°C to 250°C • Extremely rapid heating and cooling • Heating performance from 1.8 kW to 19 kW • Cooling performance from 0.5 kW to 19 kW • Magnet-coupled pumps (capacity flow rate up to 80 l/min, pump pressure up to 5.5 bar) • Air- or water-cooled • Large, intuitive 5.7 ″ TFT touchscreen • Short service times Heating Units, Refrigerating Units Temperature Controllers
