We have the right solution for you! Do not hesitate to ask our experts to advise you which product is the most suitable for your application.
This is the only way to prevent the formation of condensed water in the switch cabinet when using switch cabinets in non-heated environments and especially in outdoor areas. The switchgear cabinet air conditioning units from Dr. Neumann Peltier-Technik can easily switch between cooling and heating mode, thus ensuring a constant temperature inside the switchgear cabinet. But even without switching to heating mode, you can use our Peltier switch cabinet coolers thanks to our drain device without worrying about condensation inside the switch cabinet. Our Peltier cooling units enable hermetic insulation of the switch cabinet interior from the outside world, which guarantees trouble-free and efficient temperature control in indoor as well as outdoor areas.
Modern production facilities, especially in the field of automated manufacturing, increasingly require the installation of control cabinets at locations with changing alignment, such as on robot arms or other moving components. With our Peltier cooling units a reliable and direct cooling of the switch cabinet is possible even under these challenges (condensation must be taken care of) .

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 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 IP67 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 Mini series are the smallest Peltier coolers in our product family. This also allows efficient cooling and heating of very small applications such as small switch cabinets or electronic boxes. Like our other coolers, our Mini switch cabinet cooler is characterized by extreme efficiency and offers all the advantages of Peltier technology. For example, our mini switch cabinet cooler is also equipped with alarm relays and overheating protection and complies with protection class IP-55.
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 switch cabinet coolers of the “LRC” series were developed especially for use in machines. The cooling water usually available in these applications can be used to cool the devices without any problems. The “LRC” series combines high performance with compact size and cooling that is largely independent of the ambient temperature. The water path and the position of the hose connections can be configured as required. In addition, the “LRC” series offers all the advantages of Peltier technology, such as installation in any position and the possibility of switching to heating.
Our surface coolers extend the range of applications for Peltier temperature control technology and enable reliable and accurate cooling and heating of surfaces, liquids, containers and of course a wide variety of other materials.
Particularly under changing operating conditions, but also during regular operation, it cannot be ruled out that condensate may form inside the control cabinet. No matter how watertight the control cabinet may be – as soon as liquid has formed, it represents an immense potential danger for sensitive technology in the control cabinet. In addition to balanced temperature control, one thing is therefore of particular importance: the dehumidification of the switch cabinet.
In order to ensure the optimal functionality of your Peltier switch cabinet cooler and thus to ensure an optimal temperature control of your switch cabinet, please visit the accessories page. Here you will find many helpful accessories, which help you to control, monitor, start up and control your Peltier cooling unit.

Modern production processes require control by means of high-performance electrical components. Switch cabinets house these and other partially sensitive electronics, which must be protected from external influences. These include humidity from outside and condensation inside, as well as contamination and, above all, overheating of the components. In order to protect the components from overheating, air conditioning or temperature control of switch cabinets is usually urgently required.
In many places, the switch cabinets to be air-conditioned are located in places that are subject to special external influences. This requires a particularly robust switch cabinet cooling system that can withstand high ambient temperatures, polluted air, vibrations and sudden acceleration. The use of switch cabinet cooling units in outdoor areas also makes special demands on the air conditioning.
As Dr. Neumann Peltier-Technik GmbH, we place special emphasis on the quality of our products and thus also fulfill the requirements of the ISO 9001-2015 and OHRIS certifications and grant a 2-year warranty on all our products.
