Peter Huber KISS K20 Refrigerated Heating Bath Circulator

The Peter Huber KISS K20 is an economical, high-capacity refrigerated heating bath combination designed for reliable thermoregulation within a temperature range of -30°C to +200°C. By pairing a robust immersion circulator with a 20-liter insulated stainless steel bath, the K20 offers a spacious workspace for direct sample tempering and laboratory procedures requiring deep cooling. This unit features a 2.0 kW heating capacity and utilizes the user-friendly KISS controller, which focuses on essential functionality and safety. Designed 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 the cooling depth required for specialized refrigeration tasks.
• Heating Capacity: 2.0 kW for steady heat-up and effective thermal maintenance.
• Power Supply: 220-240V 1~/2~ 50/60Hz (Universal single-phase/two-phase compatibility).
• Controller: KISS controller with a large, bright OLED display and simple 3-button operation for ease of use.
• Safety: Class III/FL (DIN 12876) rated for use with flammable fluids; includes over-temperature and low-level protection.
• Eco-Friendly: Refrigeration bath operates with natural refrigerants to minimize environmental impact and comply with F-gas regulations.
• Stability: Reliable temperature stability of 0.05K, ideal for standard laboratory research and quality control.
• Bath Volume: 20-liter insulated stainless steel bath, offering significant immersion space and high thermal mass.

The KISS K20 is the ideal choice for laboratories that require a medium-to-large volume bath with a straightforward "set-and-forget" interface. While it excels at direct immersion tasks within the bath, the integrated pressure pump ensures efficient circulation and temperature uniformity. The rugged stainless steel construction ensures long-term durability and resistance to various thermal fluids, making it a dependable workhorse for modern chemistry and biology labs.

Frequently Asked Questions

1. What power infrastructure is required for the KISS K20?
This model is designed for a 220-240V 1~/2~ 50/60Hz supply. Its dual-frequency support (50/60Hz) makes it internationally versatile for use in various global regions without additional electrical conversion.

2. Can I use the KISS K20 for external applications?
Yes. While optimized for direct immersion work, an optional pump adapter can be fitted to the immersion circulator to allow connection to externally closed applications like jacketed reactors.

3. Why choose the KISS K20 over the K15 model?
The K20 provides a larger 20-liter bath capacity and reaches a lower minimum temperature of -30°C, whereas the K15 has a 15-liter bath and typically reaches -20°C.

4. Are natural refrigerants standard for this unit?
Yes. Huber uses natural refrigerants in the K20 refrigeration bath to ensure high cooling efficiency while significantly reducing the Global Warming Potential (GWP) compared to synthetic alternatives.

5. How do I maintain the stainless steel bath?
The bath is easily cleaned with standard laboratory detergents. It features a front-mounted drain for safe and convenient fluid changes after the system has reached a safe handling temperature.
