This LAUDA® Proline RP 1845 Refrigerating Circulator with a stainless steel bath has a filling volume of 12.5 to 19.0L and temperature range of -50 to 200°C. This refrigerating circulator has a particularly high cooling capacity of 1.6kW at 20°C. It is equipped with a Master Control Head with a 3.5kW heater power that is designed for high thermostating accuracy and reliability for applications where operating parameters are not changed or modified frequently.
The Master control head has an easy-to-read green LED display that enables convenient setting of set-temperature and control of the Varioflex pump via three operation buttons. It features indicator lights for heating, cooling, external control, and alarm, with a resolution of indication of 0.01°C and a setting resolution selectable as 0.1 or 0.01°C. The device has a selectable operating temperature range and an additional button for over-temperature protection. Graphical user guidance provides easy and intuitive operation, with adaptive control that saves time-consuming calculation of control parameters. External temperature control is provided via Pt100. Master version devices can be retrofitted with the Command remote control, which are simply connected to the control head. The thermostat automatically recognizes and controls all newly installed modules.
The Proline RP 1845 uses the patented SmartCool system for up to 75 percent energy saving with digital cooling management. The PowerAdapt system adjusts power consumption allowing use of the maximum available output from the power supply system. It also has an optical and audible alarm function, a simple temperature probe calibration, two insert ports for LiBus modules, and an integrated mains network safety device. Start mode control can be automatic or manual. The pump flow can be easily distributed by means of a bypass valve, allowing simultaneous connection of two external applications. Pump connections are located on both the side and the rear for flexible connection of external applications from different sides.
The Varioflex pump is a high-performance pressure-suction pump with eight pump capacity settings to be connected to open and closed circuits. It is suitable for internal and external applications, and the pump power can be readily adapted to respective applications. Its low energy input makes working at the lowest temperatures possible. The patented low-level protection (DGM) is an additional safety advantage.
Standard features of the Proline RP 1845 Refrigerating Circulator include a bath cover and 2 nipples and 4 closing plugs for pump connections. Applications include temperature control for chemical synthesis, tests on electronic components at different temperatures, temperature control of measuring structures in process technology, and heating and cooling of glass reactors. It is designated Safety Class II, FL for use with flammable liquids.
