Peter Huber KISS K12 Refrigerated Heating Bath

The Peter Huber KISS K12 (Order No. 2009.0020.98) is an economical and highly efficient refrigerated heating bath designed for direct thermoregulation within the laboratory. By combining a powerful immersion circulator with a high-quality insulated refrigeration bath, the K12 offers a versatile temperature range of -20°C to +200°C. This model is specifically engineered to use natural refrigerants, making it an environmentally friendly choice for modern research facilities. Managed by the intuitive KISS controller, it features a large, bright OLED display and simple menu navigation, providing a reliable solution for routine tasks like sample cooling, materials testing, and chemical analysis.

Key Features:

• Eco-Friendly Cooling: Utilizes natural refrigerants in compliance with environmental standards, providing efficient cooling down to -20°C without harmful CFCs.
• Wide Temperature Spectrum: Seamlessly transitions from cooling at -20°C to heating at +200°C, suitable for a vast array of laboratory protocols.
• KISS Controller: User-friendly interface with an OLED display that simultaneously shows setpoint, actual temperature, and safety status (Tmin/Tmax).
• High Heating Power: A 2.0 kW heating system ensures rapid heat-up times and excellent recovery after adding cold samples.
• Power Supply: Configured for 200-240V 1~/2~ 50/60Hz, ensuring stable performance on standard high-voltage laboratory circuits.
• Insulated Stainless Steel Bath: The 12-liter bath is constructed from corrosion-resistant stainless steel and features premium insulation to maximize thermal efficiency and stability.
• Safety and Reliability: Classified as Safety Class III/FL (DIN 12876). Includes adjustable over-temperature protection and a low-level sensor for unattended operation.
• Digital Connectivity: Equipped with USB and RS232 interfaces for straightforward data logging and laboratory documentation via PC.

The KISS K12 is a "Plug & Play" solution that balances low-cost ownership with professional-grade performance. While optimized for internal bath applications, it can be easily adapted for externally closed circuits using an optional pump adapter, making it a flexible asset for any growing laboratory.

Frequently Asked Questions

1. Can the KISS K12 be used for external applications?
Yes. While its primary design is for internal bath use, you can fit an optional pump adapter (Order No. 6140) to control the temperature of externally closed systems, such as a small jacketed reactor.

2. What is the difference between the KISS and Pilot ONE versions of this unit?
The KISS model offers a stability of ±0.05 K and a fixed-speed pump. The Pilot ONE version (CC-K12) provides higher stability (±0.02 K), a touchscreen interface, and a variable-speed pump suitable for external open applications.

3. Is the refrigeration system always running?
The refrigeration system is manually or automatically engaged depending on your setpoint. For temperatures significantly above ambient, the compressor is typically turned off to save energy and extend the life of the unit.

4. Does this unit require specialized maintenance for the natural refrigerant?
No, natural refrigerants are treated similarly to standard ones in terms of maintenance. However, they have the advantage of being exempt from many of the strict F-gas regulations, simplifying long-term compliance.

5. Which thermal fluid is best for the full -20°C to +200°C range?
A multi-grade silicone oil like Huber SilOil M40.165/220.10 is often used, but you must ensure the fluid’s viscosity remains manageable at -20°C while remaining stable at +200°C.
