Peter Huber CC-K25 Refrigerated Heating Bath Circulator

The Peter Huber CC-K25 is a high-capacity refrigerated heating bath combination designed for precise thermoregulation within a temperature range of -30°C to 200°C. By integrating a high-performance immersion circulator with an expansive 25-liter insulated stainless steel bath, the CC-K25 provides a versatile workspace for direct sample immersion and sufficient reservoir capacity for external systems. This unit features a 2.0 kW heating capacity and is managed by the premier Pilot ONE controller, which offers a 5.7" touchscreen interface and industry-leading temperature stability of 0.02K. Engineered for global laboratory standards, this model is compatible with 220-240V 1~/2~ 50/60Hz power supplies and utilizes eco-friendly natural refrigerants as standard.

Key Features:

• Temp Range: -30°C to 200°C, providing deep refrigeration and high-heat versatility.
• Heating Capacity: 2.0 kW for rapid temperature ramping and stable thermal maintenance.
• Power Supply: 220-240V 1~/2~ 50/60Hz (Universal compatibility for single and two-phase grids).
• Large Capacity: 25-liter insulated stainless steel bath, ideal for bulk samples or as an external reservoir.
• Controller: Pilot ONE with TFT color touchscreen, featuring "Plug & Play" technology and E-grade "Professional" functionality.
• Pump System: High-performance variable speed pressure/suction pump, suitable for both internal tasks and external open applications.
• Eco-Friendly: Charged with natural refrigerants to ensure a sustainable and future-proof laboratory operation.
• Precision: Superior temperature stability of 0.02K for high-sensitivity "Compatible Control" (CC) applications.
• Safety: Class III/FL (DIN 12876) compliant; includes adjustable over-temperature and low-level protection.

The CC-K25 is specifically designed for laboratories that require a large immersion volume without sacrificing the precision of high-end circulators. The variable speed pump allows for fine-tuning of the flow to match the resistance of external loops or the fragility of glassware. With the Pilot ONE’s integrated data logging and ramp functions, the CC-K25 is a complete solution for complex thermal profiles in research and industrial production.

Frequently Asked Questions

1. What power infrastructure is required for the CC-K25?
This specific model is designed to operate on a 220-240V 1~/2~ 50/60Hz supply. This makes it highly versatile for different international electrical standards, supporting both 50Hz and 60Hz frequencies.

2. Can the CC-K25 handle external closed applications?
Yes. While it is standardly equipped for bath and external open work, a pump adapter (optional) can be easily fitted for the thermoregulation of externally closed systems like reactor jackets.

3. Why choose the CC-K25 over a smaller K12 or K15 model?
The K25 offers a larger 25-liter bath and reaches a lower minimum temperature of -30°C, providing more workspace and deeper cooling capacity than the smaller 12 and 15-liter units.

4. How does the variable speed pump benefit my work?
The Pilot ONE's variable pump control allows you to reduce turbulence for delicate samples within the bath or increase pressure to maintain high flow rates in long external hoses.

5. Is the bath insulated?
Yes, the refrigeration bath is high-quality insulated stainless steel. This prevents energy loss at high temperatures and eliminates ice buildup on the bath exterior during low-temperature operation.
