Circulation cryostat Proline Kryomate RP 4090 CW

Description
The air- and water-cooled Proline Kryomate RP 4090 CW are refrigerated circulators (cryothermostats) with large bath openings and selectable bath volumes (32.0 or 44.0 L). They combine microprocessor control with integrated cooling for precise temperature control in laboratory and industrial tempering applications.

Features

• Thermostatic bath/circulator with latest microprocessor technology and integrated cooling system
• Input via cursor keys, numeric soft keys or both; additional Tmax key for overtemperature
• SelfCheck assistant for system diagnosis
• Low-level and overtemperature protection for use with non-flammable liquids
• Programmer with 150 temperature/time segments, up to 5 separable programs
• Adjustable bath circulation to suit the application
• SmartCool system for energy-saving digital cooling management with compressor on/off control
• Uses traditional refrigerants (HFCs) in accordance with EU regulation (EU) 573/2024
• Back-lit graphic LCD display with selectable display modes
• Detachable command console for remote operation
• Fully electronic continuous PID controller for internal and external control
• Optically isolated RS232/485 interface standard
• Timer function for switch-on, standby or program execution
• Pump connectors on side and rear with installed bypass
• Electronically controlled heating of bath edge and bridge to prevent condensation and freezing
• Additional green LED temperature display
• EasyUse system for simple operation
• PowerAdapt system to optimize heating use within the available power supply
• Upgradeable with up to 2 interface modules (RS232/485, Profibus, analogue/contact modules, Ethernet-USB)
