Reliable performance for flexible applications
The DYNEO system impresses with advanced technology solutions that make handling different temperature control fluids much easier. Its multilingual 3.5-inch color display enables intuitive control of all functions. The thermostat's pump delivers up to 27 l/min and achieves a pressure of up to 0.7 bar. This makes the device ideal for external applications where constant liquid temperature control is required, for example in chemical or pharmaceutical laboratories.
The most important features at a glance:
- Working temperature range from -30 to +200 °C
- Filling volume of 3 to 4 liters for flexible baths
- Optimized cooling coil for more space inside
- Adjustable pump capacity with 8 to 27 l/min
- Integrated Pt100 connection for external measurements
- 3-point calibration for exact temperature accuracy
- Integrated drain cock for safe draining
In addition, the device has a USB interface that can be easily connected for data logging or remote control. Other interfaces such as RS232 or analog I/O are optionally available. The removable ventilation grille reduces maintenance requirements and the integrated bath cover protects the medium from contamination.
High safety and compliance with standards
The device complies with the requirements of DIN 12876 and is classified as III (FL). With protection class IP 21, it is protected against foreign bodies and dripping water. The temperature control is based on the PID3 control algorithm and guarantees extremely stable control even with rapid temperature jumps. Thanks to the high-quality stainless steel bath tub, a long service life is guaranteed even with intensive use.
In addition, the model works very precisely in an ambient temperature range of +5 to +40 °C, so that the performance data can be reliably retrieved even in more demanding process environments.
Practical application examples
- Chemical synthesis: Precise cooling and heating react to the smallest temperature fluctuations, for example in reactions with ethanol or methanol.
- Pharmaceutical test procedures: Maintaining constant temperature conditions during solubility testing or storage tests.
- Research and development: Temperature control of samples in bioreactors or reactor systems for reliable test results.
- Industrial quality assurance: Reproducible temperature control for testing materials such as plastics and metals.
FAQs
How is temperature stability achieved
?
The device uses a PID3 control algorithm. This constantly measures the deviation of the actual temperature from the set temperature and continuously adjusts the heating and cooling output to enable a deviation of just ±0.01 °C.
Can I use different temperature control fluids?
Yes, the system is versatile. The requirements are a maximum viscosity of 50 cSt and compatibility with the materials of the device. Typical media are ethanol, water-glycol mixtures or silicone oils.
How does the external application work?
Hoses with an internal diameter of 8 or 12 mm are connected to the application via connections (M16x1). It is easy to switch between internal and external circulation so that the cooling circulation thermostat can be used for a wide range of scenarios.
Are there any special safety functions?
In addition to the solid technical design, the model has an alarm function and a cut-out in the event of overtemperature. Stable operation is also guaranteed at ambient temperatures of up to +40 °C.
How does maintenance work?
The removable ventilation grille allows for easy cleaning. The drain tap makes it easier to empty and change the medium. This minimizes downtimes and increases operational safety.
Conclusion
This model offers extremely flexible and precise temperature control. Thanks to its wide operating temperature range, powerful pressure pump and intuitive controls, it is ideal for use in chemical, pharmaceutical and industrial laboratories. Temperature stability is maintained even under demanding ambient conditions, which is particularly appreciated in quality assurance and research. With its sophisticated design and extensive interface solutions, this device represents a future-proof investment for many areas of application.
