Peter Huber KISS 205B Refrigerated Heating Bath

The Peter Huber KISS 205B (Order No. 2004.0009.98) is a high-quality heating circulation thermostat designed for reliable thermoregulation in laboratory and industrial settings. Featuring a 5-liter stainless steel bath and a powerful 2.0 kW heater, this unit is engineered for the temperature control of objects placed directly in the bath as well as externally connected applications. Managed by the user-friendly KISS controller, the 205B offers a perfect blend of modern technology and simple operation. With its bright OLED display and intuitive 3-button navigation, it serves as an excellent basic solution for routine laboratory tasks such as sample tempering, analysis, and materials testing up to 200°C.

Key Features:

• Temperature Range: Standard heating from +45°C to +200°C. The integrated cooling coil allows for temperatures as low as -30°C when connected to an external cooling source.
• KISS Controller: Features a high-contrast OLED display that simultaneously shows setpoint, actual value, Tmin, and Tmax for easy process monitoring.
• Power Supply: Designed for international compatibility with a 200-240V 1~/2~ 50/60Hz electrical requirement.
• Dual Pump Action: Equipped with a reliable pressure and suction pump that ensures excellent temperature homogeneity and flow for external circuits.
• Safety and Reliability: Rated Safety Class III/FL (DIN 12876) for use with flammable and non-flammable liquids. Includes adjustable over-temperature and low-level protection.
• Robust Construction: The 5-liter bath and all moistened parts are made of high-quality, corrosion-resistant stainless steel.
• Connectivity: Standard USB (Device) and RS232 interfaces allow for digital data logging and basic remote communication.
• Eco-Friendly: Features an energy-efficient design and an Autostart function to resume operation safely after power interruptions.

The KISS 205B is a dependable workhorse for laboratories requiring consistent thermal performance without the complexity of high-end controllers. Its compact design and rear-mounted M16x1 pump connections make it easy to integrate into existing laboratory setups or process plants.

Frequently Asked Questions

1. How do I achieve the lower temperature limit of -30°C?
The 205B is a heating circulator with an integrated cooling coil. To reach sub-ambient temperatures, you must connect the coil to an external cooling source, such as tap water (for temperatures near +20°C) or an immersion cooler/refrigerated chiller for depths down to -30°C.

2. Can I use the KISS 205B for external closed systems?
Yes. The unit is fitted with M16x1 pump connections, making it ideal for the thermoregulation of jacketed reactors, condensers, or other closed-loop laboratory equipment.

3. What is the main difference between the KISS and Pilot ONE models?
The KISS controller is a value-oriented solution with a fixed-speed pump and a 3-button interface. The Pilot ONE models (like the CC-205B) offer a large touchscreen, variable-speed pumps, and advanced programming capabilities.

4. Is the bath suitable for flammable liquids?
Yes, its Safety Class III/FL rating means it is specifically designed
