DNPT introduces the new TEC controllers! - Dr. Neumann Peltier-Technik GmbH

Modular, precise, powerful, and scalable – temperature management that pushes boundaries.

We are proud to announce the launch of our latest innovation: the DNPT TEC controllers — a response to the growing demands for precision, performance, connectivity, and integration in thermoelectric systems. Building on decades of expertise and close collaboration with our customers, these controllers offer exceptional flexibility for a wide range of applications where maximum accuracy, stability, and process control are essential.

Our Goal: Thermal Excellence in Every Application

Our TEC controllers benefit from nearly 70 years of expertise at Dr. Neumann Peltier-Technik GmbH in the field of thermoelectric technology. They are designed not only for current developments in active, coolant-free temperature control but, thanks to their flexibility, also for areas that do not yet exist today.
At the same time, they already perform everyday tasks within our systems with reliability and precision.

The PWR-CTRL System

At the heart of the DNPT TEC Controllers are the Peltier modules, which we also supply. Developed in Germany and manufactured within the EU, our controllers are available in three performance levels (XS, M, and L, ranging from 150 to 1,500 watts of Peltier output power) and offer:

Outstanding temperature stability: Our PWR-CTRL systems achieve temperature stability and precision of up to ≤ 0.01 K – essential for critical applications in medical technology, analytics, and precision manufacturing.
Consistent power output:A precise output current with a ripple of less than 1% increases the lifespan and efficiency of your Peltier elements.
High integrability: Integrated GPIOs enable versatile control of both the controller itself and its peripherals. This opens up a wide range of customization and integration options to meet specific application requirements.
Precise measurements: A 24-bit dual ADC enables highly accurate temperature measurements using Pt100, Pt1000, AD590, or NTC sensors, ensuring you always maintain full control over your thermal processes.
Seamless peripheral integration: PWR-CTRL TEC controllers come with integrated drivers for peripheral components, allowing fans, pumps, signal transmitters, and, for example, level sensors to be connected directly without additional effort.
Industry standards: With our plug-on accessory boards, communication is available via UART, RS232, RS422/485, and USB. With our COMM-PRO communication extension, additional interfaces such as REST API and a web server are provided. For direct control, a 2.83″ membrane keypad or a touchscreen of the same size can be used. Additional boards include a DC/DC converter, an I²C/Aout board, and a PWR/Aout module.

Our priority: Full control over your application.
Our TEC controllers feature active and seamless monitoring, which gives you full control over your temperature control application. The integrated auto-tuning enables control that is ideally tailored to your application, without manual and time-consuming fine-tuning.

Several NTC temperature sensors monitor temperatures at different positions in your system, giving you a complete overview of the current system status. Two high-resolution temperature sensors (choice of PT100 or PT1000 in 2 or 4-wire circuit) precisely reflect the control variable to be tempered – you choose which of the sensors is to be controlled and can place them in the position that is most profitable for your application.

Also for critical processes: Absolute security and fallback mechanisms

Even perfectly designed systems can be subject to malfunctions. We have integrated a multi-level warning system that can be configured for your application so that these can be checked quickly:

All critical functions – both temperature control and monitoring as well as all peripheral connections – can be equipped with warning and safety shutoff levels.

This allows you to maintain an overview even in critical situations and counter errors in the setup or external disruptions as quickly as possible without risking long downtimes.

Networking and communication: COMM-PRO for intelligent systems

Peltier-based applications are complex and often interconnected. TEC controllers frequently provide the foundation for precise temperature control, but they do not enable user-friendly or seamless system integration.

We think so: It could be better!

The COMM-PRO communication module takes the DNPT TEC controller to a new level and enables integration into modern, networked environments:

Remote control: The integrated web server and REST API allow users to control and monitor the system remotely. This is particularly advantageous in distributed environments or for systems that are difficult to access.
Multi-node management: A central function of the COMM-PRO module is the ability to monitor and control up to 16 interconnected nodes. This enables efficient management of complex thermoelectric systems, for example in the temperature control of medical reactors.
Data logging: The real-time clock and file system enable seamless 24/7 data logging with a capacity of over a year. This ensures comprehensive analysis and documentation of the thermal processes.
Touch display: The COMM-PRO module enables the connection of a 2.83-inch touch display with which up to 2 nodes can be controlled directly – ideal for use in laboratory environments or in field service.

For applications that only require a reduced communication capability or no HMI, our PWR-CTRL TEC controllers can alternatively be combined with specialized, compact and cost-optimized communication modules. Serial protocols such as RS232, RS485 or RS422 are available as standard.

Modular architecture for maximum flexibility

TEC controllers from DNPT are characterized by a modular design, which is complemented by a large selection of accessories and interface boards. This allows you to tailor the system precisely to your needs and implement the optimum solution for your individual application.

Areas of application

The DNPT TEC controller is predestined for a wide range of applications:

Analytical instruments: Precise temperature control is essential for accurate and reliable measurements or analytical processes such as PCR tests.
Medical technology: In the cooling of medical devices and in patient-oriented diagnostics.
Industrial automation: For temperature stabilization of lasers, optical systems and electronic components.
Telecommunications: In the cooling of sensitive components in telecommunications systems in the smallest of installation spaces, such as in the field of satellite communications.
Research and development: For experiments that require high-precision temperature control.

The DNPT TEC controller represents more than just an improvement – it’s a paradigm shift in thermoelectric control technology. Contact us today to discuss your specific requirements and learn how the TEC controller can optimize your applications!
