Highlights at a glance

LabChill Recirculating Thermostats

Powerful Peltier-Cooling- & Heating unit
The optimised Peltier cooling unit with its cooling capacity of 600 watts forms the heart of the LabChill circulators and thus meets even the most demanding temperature control tasks. The use of Peltier technology enables not only cooling but also heating operation. An integrated boost mode increases the power additionally for a short time to enable a fast approach to the target temperature.


Noise- optimized operation
LabChill Peltier circulators are optimised for use in laboratories and therefore take into account the requirements for efficient working conditions. Low-noise fans avoid disturbing noise emissions. The silent mode of the Peltier chiller ensures that the Peltier chiller emits only the necessary amount of noise and regulates the fan speed depending on the required cooling capacity.


Easy operation
An integrated 2.83″ touch display with intuitive menu navigation enables easy operation of the LabChill Peltier chiller. In addition to the displays for setting and monitoring the temperature, the display has status indicators and thus always provides an overview of the current operating status.

LabChill Recirculating Thermostats

Integrated Peltier-Controller
The specially developed controller of the LabChill Peltier thermostat is the brain of the chiller. It enables precise temperature control with a temperature stability of 0.05 K. Furthermore, critical functions of the Peltier chiller such as critical temperatures and tank levels are constantly monitored to ensure operational safety at all times.


Various communication interfaces
LabChill Peltier circulators can be ideally integrated into the laboratory environment through various communication interfaces. In addition to LAN, RS232 or RS485 is also provided. Possibilities of connection via W-Lan and control via a web-based user interface will follow.


Plug-In Connectors
The LabChill Peltier circulators feature easy connection to your laboratory application. Suitable plug-in fittings are supplied and are self-sealing to prevent unintentional leakage. The tank can also be emptied by means of a plug-in hose.

LabChill Peltier circulators are not only the most powerful systems of their kind, but also take into account contemporary requirements for ecological aspects. The high output of 600 watts also enables LabChill thermostats to be used for recooling rotary evaporators, for example. While conventional compressor systems rely on evaporators and require the use of environmentally harmful refrigerants, Peltier chillers do not require any refrigerants at all. The heart of the LabChill thermostats is the performance-optimised Peltier unit, which uses semiconductor modules to create the temperature gradient. This also enables almost vibration-free operation, as no rotating components are necessary.
Peltier thermostats of the LabChill series also use current as a control variable for temperature control. Since this can be precisely controlled, temperature stability is possible, which can only be achieved with Peltier technology. Peltier technology guarantees a temperature stability of < 0.05 K and is also suitable for use in highly temperature-sensitive applications such as test benches. Since the operating mode of the LabChill Peltier thermostat can be easily switched between cooling and heating mode, a wide temperature range can be realised. Temperatures between -20°C and + 70°C can be freely set.
The integrated Peltier controller takes care of the precise control. The specially developed controller has extensive functions and safety features. Temperatures are not only precisely controlled, but also constantly monitored and downtimes are avoided by early warnings. Several communication interfaces, including RS232, LAN, W-Lan and control via web server offer endless possibilities for integration. In this way, the LabChill Peltier circulation thermostat can be integrated into any application and at the same time offers the possibility of achieving a high degree of automation to increase productivity.

Examples of possible applications for the LABChill Peltier circulation thermostat:

LabChill Recirculating Thermostats

Re-cooling of rotational evaporators

The LABChill ensures a constant and low temperature of the cooling medium during the immersion of the flask in the heated water bath. The condensate precipitates at the cooling coil through which the cooling medium flows. The Peltier cooler enables fast and efficient condensation. Compared to compressor coolers, the LABChill thus reaches the target temperature much faster and can reduce process times. The use of Peltier coolers without refrigerants enables largely maintenance-free operation and meets the ecological requirements of modern laboratories.
