Peltier cooling units offer far more than just efficient control cabinet cooling. In addition to cooling, they also enable targeted heating of control cabinets, ensuring reliable enclosure climate control under a wide range of operating conditions. In unheated environments and outdoor applications in particular, controlled temperature regulation is essential. Only through active heating can the formation of condensation inside the control cabinet be effectively prevented – a key factor for the operational safety of sensitive control electronics.
The enclosure climate control units from Dr. Neumann Peltier-Technik enable an easy switch between cooling and heating modes, ensuring a constant internal temperature. Alternatively, our Peltier control cabinet coolers can also be operated without heating functionality: thanks to an integrated condensate drainage system, moisture formation inside the enclosure is reliably controlled. Another advantage of Peltier technology is the hermetic separation of the enclosure interior from the surrounding environment. This enables particularly clean, low-maintenance, and efficient climate control in both indoor and outdoor applications.
Our Peltier cooling units are fully orientation-independent, making them an ideal choice for modern production systems, particularly in automated manufacturing. Control cabinets are increasingly installed on moving components such as robotic arms and other dynamic machine elements. Even in these challenging environments, our systems provide reliable direct cooling while effectively managing condensation risk.

Our series switch cabinet coolers cover a wide range of applications. The different series differ in size, operating temperature and cooling capacity. If you are not sure which one is the right one for you, you can use our calculation tool.
The PROTEMP series control cabinet coolers are available in various sizes with an output range from 45 to 220 watts. They feature a compact design and very high efficiency, delivering excellent performance despite their small size.
The switch cabinet coolers of the “Standard” series are available in three sizes, each with three performance classes. They are characterized by their compact design and very high efficiency and offer excellent performance despite their small size. All switch cabinet coolers of the “Standard” series are equipped with overheating protection and alarm relays. The exterior has been designed to meet IP-67 protection class.
The switch cabinet coolers of the HL series are available in three different sizes and are characterized by a particularly high operating temperature range. This means that the units in our HL series can be used in a working range from -40°C to +90°C without any problems. Like all our units, a wide range of accessories is available on request. Of course we are also happy to adapt our switch cabinet coolers to your specific application! The units of our HL series are partly based on the units of the Standard series. Thus, a unit of the Standard Series can be easily exchanged for a unit of the HL Series of the same size. In the following you will find variants of our HL series:
The switch cabinet coolers of the AC series are available in three sizes, whereby each size in turn can be designed in two different performance levels. Our units of the AC series differ from our other units by an already integrated wide range power supply. This means that AC series units can be used worldwide without further adjustments. Like our Standard Series Cabinet Coolers, our AC Series Cabinet Coolers are designed with overheat protection, alarm relays and an IP-67-rated exterior. Below you will find the variants of our AC series:
The LRC series control cabinet coolers have been specifically developed for use in machinery applications. The cooling water typically available in these environments can be easily used to operate the units. The LRC series combines high performance with a compact design and provides cooling that is largely independent of ambient temperature.
The water circuit and the position of the hose connections can be configured freely. In addition, the LRC series offers all the advantages of Peltier technology, such as installation in any orientation and the option to switch to heating mode.
Our surface coolers extend the application range of Peltier temperature control technology, enabling reliable and precise cooling and heating of surfaces, liquids, containers, and a wide variety of other materials.
Especially under changing operating conditions, but also during regular operation, condensation can form inside the control cabinet. Even if the enclosure is highly water-tight, any accumulated moisture poses a significant risk to sensitive internal electronics.
In addition to stable temperature control, one factor is therefore crucial: effective control cabinet dehumidification.

Modern production processes require the use of high-performance electrical components for precise control. Control cabinets serve as protective enclosures for sensitive electronic systems and must be reliably safeguarded against external influences. These include external moisture, internal condensation, contamination, and, in particular, the risk of overheating.
Professional control cabinet climate control or enclosure cooling is therefore essential in most applications to ensure the functionality and long service life of the installed components.
In many applications, control cabinets are installed in demanding environments with increased operational stress. In such conditions, robust cooling solutions are required to ensure reliable performance even under extreme circumstances. These include high ambient temperatures, dust- and dirt-laden air, as well as vibrations or sudden mechanical impacts.
In outdoor applications in particular, enclosure cooling systems must meet additional requirements. The cooling units used need to be not only powerful but also highly resistant to weather influences and temperature fluctuations.
