Presto A45 and A45t process circulators, which expand Julabo’s portfolio of the newly developed Presto family, are suited for particularly demanding temperature-controls tasks in laboratories and industrial plants; for example, for the temperature control of reactors, material stress tests, or temperature simulations. The units cover a working temperature range from -45 to +250°C (-49 to +482°F) and provide up to 3.4-kW cooling capacity. The heating capacity of the A45 is 6 kW and double for the A45t at 12 kW, permitting the two temperature control systems to compensate exothermic and endothermic reactions extremely fast, the company claims. The units are equipped with maintenance-free pumps delivering up to 3.2 bar (46 psi) pressure and a flow rate of up to 80 L/min (21 gal/min). The pump performance can be controlled either in four stages or via a preset pressure value. The A45 and A45t are operated via an integrated 5.7-in industrial color touch screen, and the units are constructed to save space, allowing placement close to other units or integrating them in a process plant. Interfaces allow for flexible application, e.g. control and regulation via USB interface, data logging via USB or SD card, and integration into bus solution (e.g. Profibus) remote control via Ethernet networks or wireless control with the WirelessTEMP solutions by Julabo. The company provides support with installation, calibration, provision of documents for equipment qualification, and user training.
