Frequently Asked Questions

1. How does the 208-240V power supply affect the heating capacity?
The heating output scales with the voltage: it provides 1.6 kW when running on 208V, 2.0 kW on standard 230V, and can reach up to 2.1 kW when connected to a 240V supply.

2. Can I use the KISS K6s for cooling experiments?
Yes, the integrated refrigeration system allows for active cooling down to -25°C, making it suitable for removing heat from exothermic reactions or maintaining low-temperature environments.

3. What makes the KISS controller user-friendly?
The KISS controller emphasizes "Safe & Simple" operation, featuring a bright OLED display that is easy to read from a distance and a 3-button interface that makes setting temperatures and safety limits straightforward.

4. Is this unit suitable for external applications?
Yes, the KISS K6s includes a pump adapter and M16x1 connections, making it ideal for the temperature control of external, closed-loop systems such as small reactors or refractometers.

5. Is the refrigerant used in this model environmentally safe?
Absolutely. The unit uses R290 (Propane), which is a natural refrigerant with no ozone depletion potential (ODP) and a negligible global warming potential (GWP).
