Peter Huber KISS E Immersion Circulator, Temperature Range: 25 To 200°C

The Peter Huber KISS E is a highly versatile and compact immersion circulator designed to transform any laboratory vessel into a high-precision heating bath. This unit combines the user-friendly KISS (Keeping Innovation Safe & Simple) controller with a powerful pressure/suction pump, making it an essential tool for routine tasks such as sample temperature control, analytics, and material testing. The KISS E features a robust screw clamp for easy mounting on a wide variety of bath vessels. When used as a standalone heating unit, it operates from 25 to 200°C; however, its working range can be extended down to -30°C when paired with an external cooling bath or immersion cooler. Engineered for global use, this model supports a broad 200-240V 1~/2~ 50/60Hz power supply, delivering reliable thermal maintenance across diverse laboratory environments.

The KISS E emphasizes simplicity and safety. The OLED display simultaneously shows the setpoint, actual temperature, and safety limits (Tmin/Tmax), while clear status indicators track the pump, cooling, and heating functions. For added reliability, the unit features an autostart function that automatically resumes operation after a power failure, ensuring experimental continuity. Its flexible mounting and high-performance pump make it an ideal choice for both internal bath circulation and the temperature control of external measuring devices.

Frequently Asked Questions

1. How do I reach temperatures below 25°C with the KISS E?
The KISS E is a heating immersion circulator. To achieve temperatures down to -30°C, the unit must be mounted on a refrigerated bath or used in conjunction with an external immersion cooler.

2. Can I use the KISS E for external closed applications?
Yes. While its primary design is for bath immersion, an optional pump adapter can be fitted to the rear to allow the KISS E to control the temperature of external, closed systems.

3. How does the 200-240V power supply affect the heating output?
The heater output is voltage-dependent: it provides 1.5 kW at 200V, 1.6 kW at 208V, 2.0 kW at standard 230V, and up to 2.1 kW at 240V.

4. What safety features are built into this model?
The KISS E is rated Safety Class III (FL), meaning it includes an adjustable overtemperature limit and a low-level sensor. This makes it safe for use with flammable bath fluids.

5. Is the pump speed adjustable on the KISS E?
No, the KISS E features a high-performance pressure/suction pump with a fixed speed. If you require variable speed control for delicate applications, the Huber CC-E model with the Pilot ONE controller would be the recommended alternative.
