Peter Huber KISS 202C Refrigerated Heating Bath

The Peter Huber KISS 202C (Order No. 2003.0007.98) is a compact and versatile heating circulation thermostat designed for high-precision thermoregulation in research and industrial laboratories. Featuring a durable 2-liter stainless steel bath and a robust 2.0 kW heater, this unit is engineered for both the temperature control of objects placed directly in the bath and externally connected applications. Managed by the user-friendly KISS controller, the 202C provides a functional and stylish interface with an exceptionally bright OLED display, making it the ideal practice-oriented basic equipment for routine laboratory tasks such as sample preparation, analysis, and materials testing.

Key Features:

• Compact Performance: Small footprint and low bath volume allow for rapid heating and high-speed thermal response, perfect for small-volume external applications.
• KISS Controller: A simple, intuitive menu navigation displayed on a large OLED screen. Simultaneously view setpoint, actual temperature, Tmin, and Tmax.
• Integrated Cooling Coil: Comes standard with a cooling coil for connection to (tap) water or an external refrigerator, extending the operating range down to -30°C.
• Power Supply: Configured for 200-240V 1~/2~ 50/60Hz, ensuring compatibility with standard international laboratory power outlets.
• Dual Pump Action: Equipped with a powerful pressure and suction pump made of high-resistant industrial plastic to ensure temperature homogeneity throughout the bath.
• Safety and Compliance: Classified as Safety Class III/FL (DIN 12876) for use with flammable and non-flammable fluids. Includes adjustable over-temperature and low-level protection.
• Robust Build: High-quality stainless steel bath and moistened parts ensure chemical resistance and long-term durability.
• Modern Connectivity: Includes USB (Device) and RS232 digital interfaces for easy documentation and data transfer.

The KISS 202C is the perfect balance of affordability and technical excellence. With its "Plug & Play" design and autostart function for power failures, it ensures reliable, unattended operation for your most critical thermal processes.

Frequently Asked Questions

1. How does the KISS 202C reach -30°C?
The unit features an integrated cooling coil. When connected to an external refrigerated circulator or a powerful immersion cooler, the system can regulate temperatures as low as -30°C. Using tap water alone allows for temperatures near +20°C.

2. Can I adjust the pump speed on this model?
No. Unlike the "Pilot ONE" models, the KISS 202C features a powerful pump with a fixed speed. This provides consistent, reliable flow for routine applications without the need for manual adjustment.

3. Is the bath large enough for direct sample immersion?
Yes. While compact, the 202C has a bath opening of 25mm in diameter and a depth of 150mm, making it suitable for small vials, sensors, or tubes placed directly in the thermal fluid.

4. Can the controller display the temperature of my external process?
As an optional extra (Order No. 10519), a Pt100 sensor connection can be factory-fitted to the KISS controller to display an external process temperature on the OLED screen.

5. What thermal fluids are recommended for this unit?
For temperatures up to 200°C, we recommend using Huber SilOils (such as M40.165/220.10). Always ensure the fluid's flash point is appropriate for your operating temperature.
