CW3-30P Heating Bath Circulator (30L)

CW3-30P Heating Bath Circulator (30L)

Introducing the CW3-30P Heating Bath Circulator, a high-capacity 30-liter unit designed for superior temperature precision and versatile laboratory use. This model is engineered for both internal immersion applications and for controlling the temperature of external instruments. It integrates a powerful, variable-speed pump with an intelligent, programmable controller to ensure your processes are executed with exceptional accuracy, stability, and efficiency.

Key Features:

Advanced Programmable Control:

• Intelligent Programming: Craft and save up to 10 unique programs, each containing up to 10 distinct steps. Define precise temperature ramps and dwell times, with each step programmable for up to 99 hours and 59 minutes, perfect for complex thermal cycling.
• Effortless Program Linking: Seamlessly link your stored programs to automate sophisticated, multi-stage experiments. You can also repeat program cycles up to 99 times for extended testing.
• Scheduled Start: Set pre-heating and heating times to ensure your bath reaches the target temperature exactly when your experiment needs to begin, saving valuable time.

Exceptional Performance:

• Wide Temperature Range: Operates reliably from ambient +5°C up to 150°C (Ambient +9°F to 302°F), covering a broad spectrum of heating applications.
• Outstanding Stability: Achieves a temperature stability of ±0.08°C, thanks to advanced microprocessor PID control, automatic tuning capabilities, and a three-point temperature calibration function.
• Powerful Pumping System: The robust, variable-speed pump delivers high pressure (up to 5.9 PSI) and flow rates (up to 7.4 gal/min or 28 L/min) consistently across the entire temperature range. It features 5 adjustable steps: 3 for gentle internal circulation to maintain bath uniformity, and 2 higher-power steps for circulating fluid to external devices.

User-Centric Design and Convenience:

• Intuitive Touchscreen Interface: A large, full-color LCD touchscreen with clear, easy-to-understand icons and logical menus simplifies operation, programming, and monitoring.
• Dual Timers: Features two wait on/off timer modes, programmable from 1 minute to 99 hours and 59 minutes, for enhanced operational flexibility.
• Durable and Easy-to-Clean Construction: The 30-liter bath is crafted from corrosion-resistant stainless steel. Its seamless, round-cornered design prevents leaks and makes cleaning simple. A front-access drain valve facilitates safe and easy fluid changes.
• Enhanced Connectivity: Comes standard with an RS-232 interface and an included RS-232 to USB converter for external computer control and real-time data collection. Digital input/output ports allow for interlocking with other laboratory equipment for integrated, automated workflows.
• Easy Mobility: Equipped with built-in casters and sturdy side handles, making it effortless to transport and position the circulator within your lab.

Uncompromising Safety:

• Isolated Component Design: A strategically placed baffle plate isolates the agitator, heater, and sensors from the main working area. This design minimizes fluid turbulence and protects both the user and delicate samples from direct contact with heating elements.
• Comprehensive Alarm System: A complete safety protection system provides audible and visual warnings for critical issues, including low fluid levels (to prevent dry-running), over-temperature conditions, and over-current faults, ensuring safe, unattended operation.
• Operational Security: A keypad lock function prevents accidental setting changes during critical processes. The splash-proof keypad protects the internal electronics from minor spills and splashes.
