Refrigerated thermostatic bath RB series

stainless steeldigital displaycirculation

Product description
RB series low-temperature thermostatic water baths use a fluorine-free refrigeration system with imported key components to provide stable performance. They provide a controlled liquid environment for uniform heating and cooling, suitable for constant-temperature testing and as a temperature source for processes such as reaction kettles, synthesis instruments, extraction and condensation devices across petroleum, chemical, electronics, life sciences, pharmaceuticals, food and testing laboratories.

Main features

• Digital display resolution: 0.01°C
• Temperature fluctuation: ±0.05°C
• Temperature uniformity: ±0.05°C (horizontal/vertical)
• Temperature control range: models available from -60°C up to +100°C

Technical features

• Totally enclosed, CFC-free compressor refrigeration system
• Selectable temperature ranges from -60°C to +100°C (recommended heat transfer fluids: water, ethylene glycol, alcohols depending on range)
• PID automatic temperature control with high-precision PT100 AAA sensor, large high-brightness LCD and 0.01°C display resolution
• Capacity options: 6 L to 100 L; customized tanks available
• Internal circulation: heatless centrifugal pump and porous U-shaped reflux design for turbulent flow and high temperature uniformity
• Construction: S304 brushed stainless steel tank; anti-aging electrostatic spray exterior
• Ergonomics: rounded R-corner front panel and countertop
• Drain system for easy fluid change
• Safety protections: power-off, upper/lower temperature alarms, low-liquid-level alarm, runaway temperature alarm, anti-dry-burn heating, compressor overheat/overcurrent protection

Optional functions / accessories

• External PT100 sensor for monitoring/controlling external system temperature during external circulation
• Built-in 1–30 segment program control or constant-speed program for automated temperature profiles
• RS232/RS485 communication (ModbusRTU) for PC connection
• Integrated magnetic stirring for direct stirring of beaker samples
• Built-in cooling coil for rapid cooling and control of exothermic reactions
• Height-adjustable immersion loading platform
• Horizontal configuration for compact footprint and lower center of gravity
