Peter Huber Refrigerated Bath K12

The Peter Huber K12 is a compact, high-performance refrigerated bath designed to provide a reliable cooling foundation for laboratory thermoregulation. With a 12-liter capacity and a broad temperature range of -20°C to +200°C, this unit is engineered for versatility. Part of Huber's eco-conscious lineup, the K12 utilizes natural refrigerants, ensuring a minimal environmental footprint while complying with strict F-gas regulations. While the bath provides the refrigeration power, it is designed to be paired with a Huber immersion circulator, which provides the precise PID temperature control and fluid agitation.

Key Features:

• Brand: Peter Huber
• Temperature Range: -20°C to +200°C (operational range dependent on immersion circulator)
• Bath Capacity: 12 Liters
• Refrigerant: Natural R290 (Propane) with low GWP
• Active Cooling: Continuous refrigeration system for counter-cooling across the entire range
• Cooling Capacity: 0.25 kW at 20°C; 0.2 kW at 0°C; 0.12 kW at -10°C; 0.05 kW at -20°C
• Construction: Premium stainless steel bath with high-quality insulation
• Compact Dimensions: 350 x 560 x 215 mm, ideal for crowded laboratory benches

The K12 is particularly effective for applications requiring temperature stability near or below ambient. Its active cooling system allows it to quickly dissipate heat even when working at the upper end of its temperature range. By choosing a separate immersion circulator, users can customize the level of control sophistication to meet the specific demands of their research, whether it involves internal sample tempering or external circulation.

Frequently Asked Questions

1. Why is an immersion circulator required for this bath?
The K12 is a "refrigerated base." It provides the cooling power but does not have a heating element or a temperature controller. Pairing it with an immersion circulator adds the necessary heating, pumping, and sensor logic.

2. Can this bath reach -20°C with any thermal fluid?
No. To reach the lower limits, you must use a thermal fluid with a sufficiently low freezing point, such as a water-glycol mixture or specialized Huber SilOil.

3. Is the cooling always "on"?
The unit features an active refrigeration system designed for continuous operation. This is beneficial for applications where constant heat removal is required, providing better stability than cycling systems.

4. How much space do I need for this unit?
The K12 has a footprint of 350x560 mm. Ensure you leave adequate space around the ventilation grilles to maintain optimal cooling performance.

5. Is this bath compatible with the KISS immersion circulator?
Yes. The K12 is designed to be compatible with the entire range of Huber immersion thermostats, from the simple KISS to the advanced Pilot ONE models.
