Product description
The Proline Kryomate RP 4090 CW is a thermostatic bath and circulator with integrated cooling (water-cooled condenser). Available in air- and water-cooled versions, it offers large bath openings and nominal bath volumes between approx. 30 and 40 liters, suitable for demanding laboratory and industrial temperature control tasks.

Features

• Microprocessor-controlled thermostatic bath with integrated cooling system
• Input via cursor keys and numeric soft keys; additional Tmax key for overtemperature
• SelfCheck Assistant for system diagnosis and fault indication
• Low-level and overtemperature protection for use with non-flammable liquids
• Programmer: up to 150 temperature/time segments, up to 5 separable programs
• Adjustable bath circulation to suit the application
• SmartCool energy-saving digital cooling management with compressor on/off control
• Uses conventional refrigerants (HFCs) in compliance with EU Regulation 573/2024 on F-gases
• Back-lit graphic LCD with multiple display modes
