Peter Huber CC-205B Heating Circulator Bath

The Peter Huber CC-205B (Order No. 2004.0001.01) is a high-precision heating circulator bath designed for demanding laboratory thermoregulation. This "Compatible Control" model features a wide temperature range of +45°C to +200°C, which can be extended down to -30°C using an auxiliary cooling device. Equipped with a 5-liter stainless steel bath and a powerful 2.0 kW heater, it is ideal for the temperature control of both objects placed directly in the bath and externally connected applications. The unit is managed by the sophisticated Pilot ONE controller, which provides a professional suite of functions and a high-resolution 5.7" touchscreen for intuitive process monitoring.

Key Features:

• Professional Control: The Pilot ONE controller features a brilliant 5.7" multi-touch display with graphic functions, an integrated technical glossary, and "Plug & Play" technology.
• Advanced Pump Technology: Features a powerful, continuously variable pressure and suction pump (VPC) to ensure optimal circulation and temperature homogeneity.
• Safety First: Classified as Safety Class III/FL (DIN 12876) for use with flammable and non-flammable fluids. It includes adjustable over-temperature and low-level protection.
• Glassware Protection: The pump pressure can be controlled via an optional pressure sensor to prevent breakage of sensitive external glass reactors.
• Power Supply: Designed for international versatility, operating on a 200-240V 1~/2~ 50/60Hz power supply.
• High Stability: Maintains exceptional temperature stability of ±0.02 K, ensuring precise and reproducible results for sensitive experiments.
• Connectivity: Standard interfaces include Ethernet, USB (Host and Device), and RS232, enabling easy data logging and system integration.
• Scalability: Compatible with E-grade functionality upgrades, allowing users to add features like advanced programming and cascade control as needed.

The CC-205B is the preferred choice for applications such as sample tempering, materials testing, and quality control. Its compact footprint, combined with the robust stainless steel construction of the bath, ensures long-term reliability in busy laboratory environments.

Frequently Asked Questions

1. How does the CC-205B achieve temperatures as low as -30°C?
While primarily a heating circulator, the CC-205B includes a cooling coil. By connecting an external cooling source (like tap water or an immersion cooler), the unit can regulate temperatures below ambient, reaching as low as -30°C depending on the auxiliary device used.

2. Can I use this circulator for an external open system?
Yes. The variable-speed pressure and suction pump makes this model suitable for thermoregulating both closed systems (like jacketed reactors) and external open systems.

3. What is the benefit of the Pilot ONE over the KISS controller?
The Pilot ONE offers a much larger color touchscreen, advanced programming capabilities, data logging via USB, and the "Compatible Control" variable pump, whereas the KISS controller is a basic, non-variable solution.

4. Is the pump speed adjustable?
Yes, the VPC pump speed is steplessly adjustable through the Pilot ONE interface, allowing you to match the flow rate to the specific requirements of your application.

5. What type of thermal fluids can be used?
It is compatible with a variety of fluids including water, water-glycol mixes, and silicone oils (SilOils) rated for temperatures up to 200°C.
