Dr. Neumann Peltier-Technik GmbH
About us
Dr. Neumann Peltier-Technik is your expert for thermoelectric systems, based on Peltier technology. Our product portfolio has been perfectly complemented by our new, in-house developed DNPT TEC-Controllers from our PELCORE series. These controllers are used to control Peltier-Modules, which can also be found in our portfolio. Also, we manufacture thermoelectric chillers and circulating coolers, temperature control and cooling devices for switch cabinets, housing dehumidification and custom devices according to your needs. And of course, we provide you in addition with the necessary accessories.
Since 1956 - 70 years-, we have been demonstrating our commitment to quality in the marketplace through our experience and expertise in thermoelectric technology. This has earned us an outstanding reputation and the trust of our national and international customers.
For three generations, we have been demonstrating our expertise every day through our thermoelectric devices — whether they are controllers, chillers, control cabinet coolers, dehumidifiers or custom-designed solutions. This experience is what makes us so successful both nationally and internationally.
Our customers value the efficiency and reliability of our thermoelectric solutions — devices that have long been used in industry, laboratories, aerospace, and medical technology.
At Dr. Neumann Peltier-Technik GmbH, we make a clear and uncompromising promise to deliver quality. We are certified to ISO 9001:2015 and OHRIS standards, and we check that all our products are functioning properly several times before handing them over to customers.
Make the most of the benefits of Peltier technology and visit our team at the German Pavilion for personal, expert advice.
Let us provide you with expert advice and show you how to optimally leverage the benefits of thermoelectric solutions for your application. We are your reliable partner in the product areas of TEC controllers, high-quality Peltier modules, recirculating coolers, calibration systems, enclosure coolers, and temperature control plates.

Peltier controllers: series PELCORE
Peltier controllers go by many names, such as TEC, PWR and PID controllers, but they all have one thing in common: they control Peltier elements! This is because every Peltier element must be controlled, just like a refrigerator, heater or heat pump. We developed and built the DNPT-TEC controllers to meet our requirements for control cabinets, laboratories and special equipment construction. They not only control bare Peltier modules, but also fans, pumps, signal transmitters and sensors via analogue and digital protocols, the network and the web.
These controllers are characterized above all by the following features:
- modular design
- interface flexibility
- highest precision
- efficiency across various power classes
Peltier modules
Peltier modules have a simple sandwich-like structure. A series of silicon rods are mounted between two ceramic plates, which are energized as required for heating or cooling.
However, as with anything that seems simple at first, the appeal and advantage lie in the precise design, positioning and control of this technology. Only by mastering these aspects can efficiencies of up to 94 % be achieved with minimized power consumption and a reduced number of modules.
Thermoelectric chillers: PRO- and LABCHILL
Dr. Neumann Peltier-Technik has many years of experience in laboratory technology. In 2023, they successfully introduced two designs of high-precision circulating thermostat: the LABCHILL benchtop and the PROCHILL 19-inch rack-mount solutions. Alongside the powerful 600-watt version, 400-watt solutions have been added to the range by the end of 2026. Other products in the field of laboratory technology include calibration thermostats and temperature control plates.
We design and construct customized solutions for our customers, including individual test benches, incubators for environmental simulation and assemblies for integration into existing products. As well as the thermal and mechanical design of Peltier-based cooling and temperature control solutions, we have extensive expertise in control and regulation technology (see the section on Peltier controllers).
PROTEMP cabinet temperature control / cooling
Our new generation of PROTEMP Peltier devices is being expanded to include PROTEMP 120 M Control System with integrated PELCORE control for automatic temperature control of control cabinets.
The PROTEMP Peltier temperature control devices are characterized by maximum efficiency and time-saving installation. This means not only the highest energy density with minimal space requirements, but also the simplest and fastest installation—all you need to do is connect the power supply.
Since our PROTEMP market launch in 2024, demand has been steadily increasing.
With these product enhancements, we are addressing customer requirements for more compact/smaller Peltier systems, higher cooling capacities, and the need for minimal, timesaving and safe installation of the units.
Control cabinet dehumidifier
The control cabinet dehumidifier, patented by Dr. Neumann Peltier-Technik, not only helps regulate the temperature of your control cabinet but also provides an effective dehumidification system with additional safety features.
With our new generation of professional control cabinet dehumidifier systems in the PRO-XDry series, we are meeting customer demand for high-performance, compact dehumidifiers, equipped with integrated PELCORE control. This ensures a timesaving, simple and safe installation by the user.
The PRO-XDry series of control cabinet dehumidifiers will be available in early 2027 in the following capacity class:
- PRO-XDry 10
- More PRO-XDry with higher capacity will follow shortly next year.
The number following the product name indicates the maximum dehumidification capacity in ml/h.
The dehumidifier's core component is a Peltier cooling plate located inside the switch cabinet. It collects any condensate that has formed inside the cabinet. These droplets then flow out of the cabinet interior via a safe conduit, meaning they no longer pose a threat to sensitive high-performance components. The cooling plate is equipped with intelligent temperature sensors to prevent the collected condensation droplets from freezing. Depending on the size of the control cabinet, several modules can be connected in parallel to achieve optimal results and keep the cabinet dry.
Our switch cabinet dehumidifiers are frequently used for dehumidifying laser housings or switch cabinets in battery production.
