floor-standingdigitalelectronic

Product overview The Proline Kryomate RP 3090 C is a thermostatic bath/circulator designed for industrial and laboratory temperature control with integrated cooling. It features a large bath opening and a nominal bath volume range suited to applications requiring precise control from deep cryogenic to elevated temperatures.

Features

• Thermostatic bath/circulator with microprocessor control and integrated cooling system (air-cooled or water-cooled versions)
• Input via cursor keys and numeric soft keys; additional Tmax key for overtemperature protection
• SelfCheck Assistant for system diagnostics
• Low-level and overtemperature protection for use with non-flammable liquids
• Programmer: 150 temperature/time segments, up to 5 separate programs
• Adjustable bath circulation to match application requirements
• Electronically controlled heating of bath edge and bridge to prevent condensation and freezing
• Uses permitted HFC refrigerants in accordance with EU regulation (F-gases) 573/2024
• Back-lit graphic LCD with multiple display modes
• Detachable command console for remote operation
• Fully electronic continuous controller with PID control for internal and external regulation
• Optically isolated RS‑232/485 interface as standard
• Timer for switch-on, standby or program execution
• Pump connectors on side and rear; installed bypass
• Condenser cooling: Air
• Additional green LED temperature display
• EasyUse system for simplified operation
• PowerAdapt system to maximise usable heating within power-supply limits
• Upgradeable with up to two interfaces (RS‑232/485, Profibus, analogue/contact modules, Ethernet‑USB)
• LAUDA Vario pump with 4 selectable output steps
• SmartCool energy-saving digital cooling management with compressor on/off control
• Additional pump for external application (Thread M38x1.5 O)
