Frequently Asked Questions

1. What is the benefit of the 20-liter bath in the KISS 220B?
The large 20-liter capacity and the generous 290 x 329 mm opening allow for the immersion of large samples or multiple laboratory vessels simultaneously, making it ideal for high-volume testing.

2. Can I use this circulator for external applications?
Yes, the KISS 220B includes a pump adapter and M16x1 connections at the rear, making it suitable for the temperature control of external, closed laboratory applications.

3. How does the KISS controller help in daily laboratory work?
The KISS controller is designed for maximum simplicity. The large OLED display is readable from a distance, and the 3-button interface allows for quick adjustments without the need for complex menu diving.

4. Is it possible to reach temperatures below 25°C?
Yes. While the standard heating range starts at 25°C, an optional cooling coil can be connected to a tap water supply to remove excess heat and reach temperatures as low as 20°C.

5. Is this model safe for use with flammable thermofluids?
Yes, the KISS 220B is rated Safety Class III (FL) according to DIN 12876, featuring the necessary adjustable overtemperature protection and low-level sensors for safe operation with flammable fluids.
