Recirculating Thermostats Accessories
PROChill laboratory thermostats are characterised by their compactness and high power density. This ensures a cooling capacity of 600 watts at the same temperature. A wide range of accessories simplifies the integration of the LabChill Peltier circulator into the laboratory or industrial application.
Glycotherm® heat-transfer liquids
Water-glycol mixtures for use at especially at low temperatures. Our Glycotherm products are available as Glycotherm 5, Glycotherm 20 and Glycotherm 30 with an operating temperature range down to -5 °C, -20 °C and -30 °C, respectively.
Additionally, the composition of the substances prevents algae formation during operation and thus ensures trouble-free use in your application.
Silotherm® Silicone oils
Silotherm silicone oils are especially suitable for use at high temperatures at which water or glycotherm products could outgas. The viscosity of our Silotherm silicone oils is also specifically matched to the operation with LABChill and PROChill recirculating thermostats.
Connection hoses
Our connection hoses enable quick and safe installation of the cooling-heating thermostats to the respective application.
The self-sealing connectors allow for a plug & play connection without the danger of liquid leakage when connecting the hose.
Insulated connection hoses
Insulated connection hoses are particularly suitable for applications with high temperature differences to the ambient temperature. The insulation prevents additional energy input in cooling mode or energy loss in heating mode of the cooling-heating thermostats. Our insulated hoses are also equipped with self-sealing connectors.
Examples of possible applications for the PROChill Peltier recirculating thermostat:
To ensure optimal reliability, process engineering applications and plants depend on dissipating the thermal power loss of some components. In addition to that, temperature consistency and control accuracy are crucial for analytical processes in order to achieve optimal results. The PROChill not only combines these requirements, but also enables uncomplicated installation in standard racks, especially due to its compactness with only four height units as a 19“ rack. Like all our Peltier circulators, our LABChill devices also offer freedom from refrigerants as well as a largely maintenance-free operation.
Laser-Sources
The use of temperature control plays a crucial role in ensuring repeatable operation in many applications. One example are laser sources, which only operate accurately at a specific temperature range. Accurate temperature control ensures stable operation and minimizes the risk of failure. In addition to that, precise temperature control protects the laser source against overheating, preventing potential damage to the equipment. With the right temperature control, reliable and efficient plant control is ensured, enabling optimal results and high process reliability.
Semiconductor industry
Precise temperature control of thermal chucks, as pne example for applications within the semiconductor industry, ensures optimum positioning accuracy within the specific application. Through the use of communication interfaces, extensive monitoring of the process is possible, which enables optimal control of the manufacturing process. Various parameters can be monitored and adjusted if necessary. This not only contributes to efficient operation, but also increases the reliability of the system.
Cooling of UV-lamps
The PROChill offers an ideal solution for cooling UV lamps or during lithographic processes. Waste heat is for example generated when UV lamps are used to illuminate adhesives. Efficient cooling is essential to avoid machine downtime. In addition to that, no maintenance of the cooling solution is required, which keeps the operation efficient.
Medical Applications
Among lithographic processes, imaging and analytical procedures within medical applications also require cooling and temperature control so that the components can work properly and fail-safe. The PROChill offers perfect solutions not only for these problems in medical technology. Especially in analytics, highest precision in temperature control is important. The PROChill ensures precise temperature control in order to deliver reproducible and accurate results even within the most demanding applications.
FAQ
Is the cooling capacity of the PROChill Peltier sufficient for my application?
The PROChill has a cooling capacity of 600 watts with temperature equality between the circulating medium and the ambient temperature. This makes the PROChill the most powerful thermoelectric cold-heat thermostat in its class. It can also be used to cool powerful laser heads. Our experts will be happy to check whether the cooling capacity is suitable for your individual application at any time.
Are there different fittings for connecting the fluid circuit?
On request, both the PROChill itself and the matching connection hoses can be fitted with individual fittings.
Do I need further accessories to operate the PROChill Peltier circulator?
We recommend operating PROChill cooling/heating circulators with the accessories tested for this purpose. These include suitable connection hoses and Glycotherm and Silotherm temperature control fluids.
With which circulating media can the PROChill thermostat be operated?
PROChill thermostats can be operated with water, but also water-glycol mixtures and silicone oils. Here
What do the different operating modes of the PROChill circulation thermostat do?
The ProChill has a silent mode and a boost mode. In silent mode, the fan speed is minimised to ensure the quietest possible operation. In boost mode, the Peltier power is maximised to achieve the steepest possible temperature ramps.
In which performance classes is the PROChill available?
The PROChill cold-heat thermostat is currently available with a cooling capacity of 600 watts. Other variants will follow. If you have an individual application that requires a different cooling capacity, please do not hesitate to contact us.
How accurate is the temperature control of the PROChill?
The PROChill guarantees a temperature stability of better than 0.05 °C. If your application requires a temperature that is as precise as possible, the cold/heat thermostat can also be calibrated to avoid deviations. In addition, an external temperature sensor can be used to measure the temperature directly at the application.
