Circulation cryostat Proline Kryomate RP 4050 C

Product overview
The Proline Kryomate RP 4050 C is a thermostatic bath/circulator for industrial and laboratory temperature control. Available in air- or water-cooled versions with large bath openings and bath volumes corresponding to 30 or 40 L (technical data: 32.0 / 44.0 L). Designed for use with non-flammable heat transfer fluids and configurable for different pump/output options.

Key features

• Microprocessor-controlled bath/circulator with integrated refrigeration
• Input via cursor keys and numeric softkeys; additional Tmax key for overtemperature
• SelfCheck assistant for system diagnosis
• Low-level and overtemperature protection for non-flammable liquids
• Programmer with 150 temperature/time segments (up to 5 programs)
• Adjustable bath circulation and LAUDA Vario pump with 4 selectable output steps
• Electronically controlled bath-edge and bridge heating to prevent condensation and icing
• Back-lit graphic LCD display and detachable command console for remote operation
• Fully electronic PID controller and standard optically isolated RS 232/485 interface
• SmartCool digital cooling management and PowerAdapt power management
