RW3-3035P Refrigerated / Heating Bath Circulator (30L), 230V / 50Hz

RW3-3035P Refrigerated / Heating Bath Circulator (30L, 230V / 50Hz)

Overview The RW3-3035P is a premium, high-performance refrigerated and heating bath circulator engineered for laboratory applications demanding precise and stable temperature control across an expansive range. Capable of maintaining temperatures from as low as -35°C up to 150°C, this 30-liter unit is optimized for rapid heating and cooling cycles. Its exceptional stability and uniformity make it the ideal thermal solution for sensitive equipment such as refractometers, viscometers, rotary evaporators, and for material testing where temperature accuracy is non-negotiable.

The powerful circulation pump not only guarantees consistent temperature throughout the bath but also delivers robust external circulation for a wide array of closed-loop applications, making it a versatile cornerstone for any modern laboratory. Paired with an intuitive full-color touchscreen controller and sophisticated programming capabilities, the RW3-3035P offers unparalleled control, automation, and ease of use.

Intelligent Program Control Unlock advanced automation and process repeatability with our sophisticated program controller, designed to minimize manual oversight and maximize efficiency.

• Advanced Programming: Effortlessly create, store, and recall up to 10 distinct temperature programs directly on the controller.
• Complex Multi-Step Protocols: Each program can be configured with up to 100 individual steps, allowing for intricate thermal profiles. Set each step's duration for up to 99 hours and 59 minutes.
• Seamless Operation: Stored programs can be linked together to execute complex, long-duration experiments without interruption.
• Assured Repeatability: Programs can be set to repeat for up to 99 cycles, ensuring consistent conditions for batch testing and quality control procedures.
• Time-Saving Automation: Schedule pre-heating and pre-cooling times to ensure your bath reaches the target temperature precisely when you need it, streamlining your daily workflow.

Performance & Precision

• Wide Temperature Range: Operates from -35°C to 150°C (-31°F to 302°F) with exceptional stability of ±0.05°C, ensuring reliable and repeatable results.
• Powerful Cooling Capacity: A robust 1 LBP, R-404A refrigerator delivers exceptional cooling power: 440W at -20°C, 700W at 0°C, and 880W at +20°C.
• Microprocessor PID Control: This advanced control system guarantees precise temperature management. It features automatic tuning (auto-tuning) for optimal performance under varying conditions and a three-point calibration function for enhanced accuracy.
• Adjustable 5-Speed Pump: The powerful pump (28 L/min, 5.9 PSI) can be adjusted across five speeds. Lower speeds (1-3) minimize turbulence for delicate internal applications, while higher speeds (4-5) provide powerful flow for efficient external circulation.
• Built-in Cooling Coil: An integrated cooling coil allows for rapid cooling using tap or chilled water, which is ideal for managing exothermic reactions and accelerating cool-down times from high temperatures.

Convenience & Usability

• Intuitive Touchscreen Controller: The 5.7” full-color LCD controller provides a graphical interface with clear icons and logical menus, making setup, programming, and real-time monitoring effortless.
• Dual Timer Functionality: Automate your workflow with dual wait on/off timers, configurable from 1 minute up to 99 hours and 59 minutes.
• Durable & Easy-to-Clean Construction: The 30L bath is constructed from corrosion-resistant #304 stainless steel with rounded corners to simplify cleaning. A front-access drain valve allows for convenient and mess-free draining.
• Simplified Maintenance: A detachable condenser air filter and a quick-release front grill facilitate simple, routine cleaning to maintain peak refrigerating efficiency and prolong the life of the unit.
• Eco-Friendly Design: Utilizes CFC-free refrigerants (R-507, R-404A) to comply with environmental standards. A double service valve is integrated to prevent refrigerant leakage during servicing.
• Enhanced Mobility: Equipped with heavy-duty side handles and smooth-rolling casters (with brakes) for easy transport and secure installation within your lab.
• Data Connectivity & Remote Control: An RS-232 interface is included for external PC control and data logging (a USB converter is provided). The unit is also compatible with the LC Connected mobile monitoring system (requires optional LC GreenBox) for remote monitoring via your smartphone.

Uncompromising Safety

• Isolated Design: A strategically placed baffle plate isolates the agitator, heater, and sensors from the primary work area, protecting users from direct contact with moving parts and minimizing turbulence for sensitive samples.
• At-a-Glance Visual Alerts: A three-color LED bar provides an immediate visual status of the reservoir temperature: Blue for cooling, Red for heating, and Green for in-range.
• Comprehensive Alarm System: Protects the unit and your valuable samples with audible and visual alarms for low fluid level, dry-running pump, over-temperature conditions, and over-current faults.
• Enhanced Security: A keypad lock function prevents unauthorized or accidental changes to critical settings. The keypad itself is splash-proof for durability in a lab environment.
