From a Humble Workshop to Precision Technology
Prof. Dr. Neumann was among the pioneers who recognized the potential of a technology that few people truly understood at the time. Peltier technology—the direct heating and cooling of objects using electric current, without any moving parts—was considered a promising innovation in the 1950s. Major companies invested heavily, hoping it would one day replace conventional compressor-based cooling systems.
That promise was never fully realized—at least not in the way many had expected. Peltier technology did not replace compressor-based cooling. Instead, it established its own unique strengths: quiet operation, compact design, precise temperature control, and long service life. These characteristics make it the ideal solution for precision applications and installations where space is limited.
DNPT recognized this potential early on and built the company around these advantages. Its first products included compact enclosure cooling units for industrial control cabinets, followed soon after by highly precise ice-point thermostats for laboratory applications.
When Theodor Freundorfer came across a classified ad in the Süddeutsche Zeitung in 2006—”Small electrical engineering company for sale”—he decided to take a closer look. What he found was an entrepreneur who had devoted his life to his inventions but had never truly systematized the business.
What followed were years of intensive research and development: rebuilding technical know-how, establishing robust processes, and creating the foundation for scalable quality and sustainable growth.
A Technology Reveals Its True Strengths
What sets Peltier technology apart from conventional cooling systems? It requires no refrigerants, contains virtually no moving parts, and operates with minimal noise. Instead, it provides direct, electrically controlled temperature regulation with accuracy down to a tenth of a degree. The same system can both cool and heat, integrates easily into compact designs, and delivers exceptional long-term reliability.
DNPT has consistently translated these strengths into products designed for applications where conventional cooling technologies are either unsuitable or unnecessarily complex. Today, its solutions are used across industries where precision, reliability, and compact design are essential:
- Industrial Control Cabinets: The company’s original area of expertise has evolved into today’s PROTEMP series. These thermoelectric cooling units are specifically designed for reliable temperature control in demanding outdoor environments.
- Semiconductor and Electronics Industry: Precise temperature control for sensitive electronic components.
- Laboratory Technology: Temperature control for process chambers and thermoelectric chillers for analytical instruments.
- Defense: Rugged, EMC-optimized cooling solutions designed for demanding and extreme operating environments.
One of DNPT’s proudest achievements is the PELCORE family of TEC controllers. Developed entirely in-house, they bring thermoelectric technology into the digital age with precise control, remote monitoring and maintenance, and support for modern industrial communication protocols.
30 Employees. Decades of Dedication.
When Prof. Dr. Neumann sold his company, it employed just three people. Today, DNPT has grown to around 30 employees—and one of them has been there since before Theodor Freundorfer took over.
Linda, the only employee to remain from the Neumann era, has witnessed the company’s entire transformation. Few people know DNPT’s history as intimately as she does, making her a living link between its past and present.
What makes DNPT a great place to work? Size comes at a cost. In a large corporation, it’s easy to become just another number. At DNPT, everyone knows what their colleagues are working on, and every contribution matters.
The technology is demanding, the projects are highly customized, and every customer request presents a new challenge. This is not mass production or assembly-line work—it’s precision engineering with craftsmanship and personal commitment.
“We don’t believe in off-the-shelf solutions. Every system we build is the answer to a very specific technical challenge. That’s what makes the work demanding—and that’s exactly what our people enjoy.”
From Germany to Europe and Beyond – Precision Without Borders
Today, around 70–80% of DNPT’s revenue is still generated in German-speaking markets. But its technology travels far beyond them. Customers in Germany and Austria integrate DNPT’s systems into equipment that is shipped to Taiwan, China, the United States, and many other countries.
When a service request comes in from East Asia, it is often for a system that was designed and manufactured in Bavaria—demonstrating how German engineering expertise supports critical applications around the world.
Active sales partners in Spain, Finland, Poland, and Italy are helping DNPT expand its presence across Europe and strengthen its international mindset. One partner, after completing specialized product training, placed an order for more than 70 units in a single purchase.
It is a clear demonstration that when the right people understand the technology and know how to apply it, successful partnerships—and successful business—follow.
What sets DNPT apart from its competitors? Focus. While many companies offer Peltier technology as just one product among many, at DNPT it is the company’s sole focus—and has been for decades. 100% thermoelectric. Made in Germany. Engineering expertise and application-focused consulting tailored to your specific requirements. When you choose a thermoelectric solution from DNPT, you gain more than just a product—you benefit from decades of application expertise. As one of the few manufacturers covering the entire spectrum of Peltier technology, DNPT offers everything from thermoelectric modules and complete cooling systems to advanced TEC controllers. Our exclusive focus on thermoelectric technology enables us to deliver deep expertise, innovative solutions, and application-specific support.
70 Years of Experience – Looking Ahead
Seventy years of company history are about more than celebrating a milestone. They reflect decades of technical expertise, trusted partnerships, and a continuous drive to innovate. For DNPT, this anniversary is not just a look back at what has been achieved—it is, above all, a commitment to shaping the future.
Instead of hosting a large anniversary celebration, DNPT is choosing to celebrate through personal connections and genuine appreciation. The focus is on the people who have supported the company over the years and played a vital role in shaping its success.
The roadmap for the years ahead is clear:
- New product groups: Chillers with next-generation refrigerants and communication protocols, as well as the continued development of the PELCORE product family.
- Internationalization: Expanding our global network of distribution partners and increasing our presence in high-growth international markets.
- From Component Manufacturer to System Solutions Provider: Delivering complete thermal management solutions instead of individual cooling modules.
- Sustainable Growth: Growing our team to strengthen development capabilities while preserving the close-knit culture that defines DNPT.
“Our vision is clear: to become the technological leader in industrial thermoelectric solutions. That is an ambitious goal for a company of just 30 people based in southern Germany—but it is exactly what drives us.”
Seventy years of thermoelectric expertise. Twenty years of the modern DNPT. And many more years of proving that precision engineering made in Germany is driven not by company size, but by specialization, innovation, and an unwavering focus.
