Peter Huber KISS 225B Refrigerated Heating Bath

The Peter Huber KISS 225B (Order No. 2060.0004.98) is a versatile heating bath circulator featuring an insulated 25-liter stainless steel bath and a bridge-mounted immersion circulator. Designed for precision thermoregulation from +25°C to +200°C, this unit is optimized for both direct immersion of large sample loads and external temperature control tasks. The integrated KISS controller provides a modern, practice-oriented interface with a bright OLED display, ensuring ease of use for routine laboratory applications. With its high heating power of 2.0 kW and robust construction, the KISS 225B is an ideal solution for materials testing, quality control, and large-scale sample tempering.

Key Features:

• Large Insulated Bath: Features a 25-liter high-quality stainless steel bath with premium insulation to minimize heat loss and ensure excellent temperature homogeneity up to 200°C.
• KISS Controller: Intuitive menu navigation on a large, high-contrast OLED display. Simultaneously shows setpoint, actual temperature, and safety limits (Tmin/Tmax).
• Power Supply: Configured for 200-240V 1~/2~ 50/60Hz, allowing for high-performance operation in standard laboratory environments.
• Versatile Circulation: Equipped with a powerful pressure and suction pump. With the use of a pump adapter, the unit can easily manage externally closed applications.
• Integrated Cooling Coil: Includes a standard cooling coil for connection to tap water or an external cooling source, enabling the unit to work near ambient temperatures or reach sub-ambient depths with auxiliary cooling.
• Safety and Reliability: Rated Safety Class III/FL (DIN 12876). Features adjustable over-temperature protection, low-level sensor, and an autostart function for recovery after power failure.
• Connectivity: Standard digital interfaces include USB (Device) and RS232 for straightforward data logging and laboratory documentation.
• Flexible Design: The bridge-mounted immersion circulator can be easily removed or repositioned, offering flexibility for different vessel sizes or cleaning.

The KISS 225B is engineered to provide reliable, long-term performance. By combining a large bath volume with a highly efficient heating system, it offers the thermal inertia required to keep temperature fluctuations to a minimum, even when introducing large or reactive samples into the bath.

Frequently Asked Questions

1. How does the KISS 225B handle cooling?
While primarily a heating bath, it comes with an integrated cooling coil. By circulating tap water through this coil, you can maintain temperatures close to ambient. For lower temperatures, an external refrigerated chiller or immersion cooler can be connected.

2. Can I use this unit with an external open system?
The KISS model has a fixed-speed pump. For external open applications, an optional level control system is required to maintain the fluid balance. For high-demand external open applications, the Pilot ONE version (CC-225B) with variable pump speed is recommended.

3. What are the benefits of the insulated stainless steel bath?
The 25L bath is made of high-grade stainless steel to resist corrosion. The high-quality insulation ensures that the exterior remains safe to touch even at 200°C and reduces energy consumption by maintaining heat within the fluid.

4. Is the immersion circulator removable?
Yes. The immersion circulator is bridge-mounted, meaning it can be moved or used on other compatible tanks, making it a very flexible tool for a growing laboratory.

5. Which thermal fluids should I use for 200°C?
For operation at 200°C, silicone oils (Huber SilOils) are recommended. Always ensure the fluid's flash point is significantly higher than your maximum working temperature.
