Peter Huber KISS K25 Refrigerated Heating Bath Circulator

The Peter Huber KISS K25 is a high-capacity, economical refrigerated heating bath combination designed for direct thermoregulation within a temperature range of -30°C to +200°C. By pairing a robust immersion circulator with a large 25-liter insulated stainless steel refrigeration bath, the K25 offers an expansive workspace for bulk sample tempering and laboratory procedures requiring deeper cooling. This unit features a powerful 2.0 kW heating capacity and utilizes the straightforward KISS controller, providing essential functions and reliable safety. To ensure global laboratory compatibility, this model supports a power supply of 220-240V 1~/2~ 50/60Hz and utilizes eco-friendly natural refrigerants as standard.

Key Features:

• Temp Range: -30°C to +200°C, providing the cooling depth needed for more demanding refrigeration tasks.
• Heating Capacity: 2.0 kW for efficient heat-up and high thermal stability.
• Power Supply: 220-240V 1~/2~ 50/60Hz (Universal single-phase/two-phase compatibility).
• Controller: KISS controller with a large, bright OLED display and intuitive 3-button navigation.
• Safety: Class III/FL (DIN 12876) compliant; includes adjustable over-temperature and low-level protection for use with flammable fluids.
• Eco-Friendly: Refrigeration bath charged with natural refrigerants to meet modern sustainability and F-gas standards.
• Stability: Reliable temperature stability of 0.05K, ensuring consistent results for standard research and quality control.
• Bath Construction: Large 25-liter insulated stainless steel bath designed to minimize energy loss and prevent condensation at low temperatures.

The KISS K25 is the perfect solution for users who need a large-volume bath with a simple "set-and-forget" interface. While it is primarily optimized for direct immersion work within the bath, the integrated pressure pump facilitates fluid movement for uniform temperature distribution. Its robust design and durable materials make it a long-lasting staple for heavy-duty laboratory environments.

Frequently Asked Questions

1. Why choose the KISS K25 over the K15 model?
The K25 offers a significantly larger 25-liter bath (vs 15L) and reaches a lower minimum temperature of -30°C, making it better suited for larger sample loads and deeper cooling requirements.

2. Can I connect the KISS K25 to an external jacketed vessel?
Yes. Although optimized for bath work, an optional pump adapter can be fitted to the immersion circulator to allow the thermoregulation of externally closed applications.

3. What are the advantages of natural refrigerants?
Natural refrigerants have a very low Global Warming Potential (GWP), helping laboratories comply with environmental regulations while providing efficient cooling performance.

4. How does the KISS controller handle frequency changes?
This specific model is engineered for 50/60Hz operation, meaning it can be moved between different regions (such as Europe and parts of the Americas or Asia) without requiring electrical conversion.

5. Is the bath easy to drain?
Yes, the unit features a front-facing drain port, allowing you to quickly and safely empty the 25-liter bath for fluid changes or cleaning.
