Circulation cryostat Proline Kryomate RP 3090 CW

Product overview
The Proline Kryomate RP 3090 CW is an industrial cryothermostat available in air- and water-cooled versions. It features large bath openings and bath volumes typically 23–31 L (variants up to ≈30–40 L), providing controlled tempering from -90 °C to 200 °C.

Key features

• Thermostatic circulating bath with microprocessor control and integrated cooling
• User input via cursor keys and numeric softkeys; additional Tmax key for overtemperature
• SelfCheck Assistant for system diagnosis and fault indication
• Low-level and overtemperature protection for use with non-flammable heat transfer liquids
• Programmer with 150 temperature/time segments, configurable as up to 5 programs
• Adjustable bath circulation to match application needs; LAUDA Vario pump with 4 selectable output steps
• Electronically controlled heating of bath edge and bridge to prevent condensation and icing
• High-resolution back-lit graphic LCD with multiple display modes; detachable command console for remote operation
• Fully electronic continuous controller with PID action; standard optically decoupled RS-232/485 interface
• Timer function for switch-on, standby or program execution; pump connectors side and rear with installed bypass
• SmartCool energy-saving digital cooling management; PowerAdapt for optimized heat usage within supply limits
• Optionally upgradable with up to 2 additional interfaces (Profibus, analogue/contact modules, Ethernet-USB)
• Uses traditional refrigerants (HFCs) in accordance with EU regulation 573/2024

Working range
