PRESTO & Magnum91 - High Dynamic Temperature Control Systems

Instruments of the PRESTO series are the ideal solution for highly precise, external temperature applications. They offer rapid heating and cooling, wide working temperature ranges without changing fluids. The self-optimizing controller (ICC - Intelligent Cascade Control) provides excellent temperature stability and optimized control. The classic PID control parameters are available at the touch of a button for modification at any time. All models have an interactive 4-line LCD display as well as a bright VFD-Info-Display. Reciprocal sensor monitoring, self-test after switch-on, pump motor and compressor overload protection guarantee reliable performance and provide high safety for your samples.

With the ,Magnum 91‘ JULABO offers a powerful highly dynamic temperature control system for demanding external temperature applications, like e.g. temperature control of reactors up to 50 liters. The advantages are rapid heat-up and cool-down within the working temperature range from –91 to +250°C. The water-cooled unit offers a heating capacity of 6 kW as well as a cooling capacity of 5 kW at +20°C, 4 kW at 40°C, 2.5 kW at –60°C and 0.6 kW at –80°C. The circulation pump is electronically adjustable and reaches a flow rate of 24 to 35 l/min resp. a pressure of 0.8 to 2.2 bar. With the intelligent ICC cascade temperature control rapid results with high precision are reached. The temperature stability is between +/-0.05 and +/-0.2°C. Further features are an RS232/RS485 interface, a connection for external Pt100 sensor and an early warning system for temperature limit values.
