Peter Huber CC-405 Refrigerated Heating Bath Circulator, Temperature Range: -40 to 200°C

The Peter Huber CC-405 is a robust and high-precision refrigerated heating bath circulator designed for demanding laboratory and industrial thermal management. Part of the Compatible Control series, this unit offers a versatile temperature range from -40 to 200°C, making it suitable for both high-temperature heating and deep-cooling tasks. It features the state-of-the-art Pilot ONE multi-touch controller with a 5.7" TFT color display, providing smartphone-like navigation, a technical glossary, and support for over 10 languages. With a 5-liter stainless steel bath and a powerful variable-speed pressure/suction pump, the CC-405 is ideal for the thermoregulation of external closed systems—such as double-jacketed reactors, autoclaves, and viscometers—as well as direct sample control within the bath. Its VPC (Variable Pressure Control) system ensures optimal circulation while protecting delicate glass apparatus from overpressure.

Frequently Asked Questions

1. Can this model be used as a calibration bath?
Yes, with an optional calibration insert, the CC-405 provides the high temperature uniformity and stability (±0.01 K) required for precise sensor and thermometer calibration.

2. How does the Variable Pressure Control (VPC) work?
When paired with an optional pressure sensor, VPC allows you to set a maximum pressure limit. The controller will then automatically adjust the pump speed to ensure the limit is not exceeded, protecting fragile external glassware.

3. Is this unit suitable for continuous, unsupervised operation?
Absolutely. It complies with DIN 12876 Safety Class III (FL) standards, meaning it is designed for safe, long-term operation even with flammable thermal fluids.

4. What is the benefit of the thermoregulated cover plate?
The cover plate is kept at a specific temperature to prevent the formation of condensation or ice around the bath opening, which helps maintain the integrity of the thermal fluid and keeps the workspace clean.

5. Can the controller be used remotely?
Yes. The Pilot ONE features "Plug & Play" technology and can be detached from the unit and used as a remote control via a data cable, allowing you to monitor and adjust settings from a distance.
