Peltier control cabinet cooling and air conditioning in an efficient and reliable way

Peltier cooling units from Dr. Neumann Peltier-Technik GmbH air-condition your control cabinet reliably and precisely. Our cooling units reliably protect electronic components in control cabinets against overheating, moisture and dirt. Our Peltier cooling units allow a hermetic insulation of the switch cabinet interior of the outside world, whereby a trouble-free and efficient temperature control in indoor as well as outdoor areas can be guaranteed.

Our Peltier cooling units for air conditioning of control cabinets and enclosures combine quality with the advantages of Peltier technology. These include, for example, the conversion to heating operation, completely position-independent installation and simple and quick commissioning through the electrical connection.

Peltier cooling units for control cabinet air conditioning can be equipped with sensors and control electronics as required. This avoids the formation of condensation water and achieves a high degree of efficiency of our Peltier control cabinet coolers.

  • Operating temperature: -40°C - +70°C
  • Protection category: IP55
  • Supply voltage: 24 V
  • RU certified

The Mini series control cabinet coolers are the smallest Peltier coolers in our product family. This also allows efficient cooling and heating of small applications such as small control cabinets or electronic boxes. Like our other coolers, our mini cabinet cooler is extremely efficient and offers all the advantages of Peltier technology. Our mini cabinet cooler is also equipped with alarm relays and overheating protection and complies with protection class IP-55.

  • Operating temperature: -40°C - +70°C
  • Protection category: IP67
  • Supply voltage: 24 V
  • RU certified

The control cabinet coolers of the “Standard” series are available in three sizes, each with three performance classes. They are characterised by their compact design and very high efficiency and offer outstanding performance despite their small size. All “Standard” series control cabinet coolers are equipped with overheating protection and alarm relays. The exterior is designed to meet IP67 protection.

  • Operating temperature: -40°C - +70°C
  • Protection category: IP67
  • Supply voltage: 90..305 V-AC | 47..63 Hz
  • RU certified

The AC series control cabinet coolers are available in three sizes, with each size available in two different power ratings. Our AC series units are distinguished from our other units by an integrated wide-range power supply. This means that AC Series units can be used anywhere in the world without further adaptations. 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:

  • Operating temperature: -40°C - +90°C
  • Protection category: IP67
  • Supply voltage: 24 V

The control cabinet coolers of the HL series are available in three different sizes and are characterised by a particularly high operating temperature range. The units of our HL series can therefore be used in a working range from -40°C to +90°C without any problems. Like all our devices, you can obtain a wide range of accessories 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 device of the standard series can be exchanged problem-free against a device of the HL series in the same size. In the following you will find variants of our HL series:

  • Operating temperature: +5°C - +90°C
  • Protection category: IP67
  • Supply voltage: 24 V

The control cabinet coolers of the “LRC” series were specially developed for use in machines. The cooling water usually available in these applications can easily be used to cool the units. The “LRC” series combines high performance with compact size and cooling that is largely independent of ambient temperature. The water path and the position of the hose connections can be freely configured. In addition, the “LRC” series offers all the advantages of Peltier technology, such as position-independent installation and the option of switching to heating.

Control cabinet air conditioning and cooling to meet the requirements of modern production mechanisms and control electronics

Modern production processes require control by means of high-performance electrical components. Switch cabinets house these and other partly sensitive electronics, which must be protected from external influences. In addition to moisture from outside and condensation water inside, this also includes contamination and, above all, overheating of the components. In order to protect the components from overheating, air conditioning or temperature control of control cabinets is generally urgently required.

In many places, the control cabinets to be air-conditioned are installed in places that are subject to particular external influences. A particularly robust control cabinet cooling system is required that can withstand high ambient temperatures, polluted air, vibrations and sudden accelerations. The use of control cabinet cooling units in outdoor applications also places special demands on air conditioning.

Control cabinet heating and cooling combined in one unit to ensure optimum temperature control

In addition to efficient cooling of switch cabinets to prevent overheating and the associated overloading of electronic components, temperature control and air conditioning of switch cabinets also includes heating of the interior of the switch cabinet. This is the only way to prevent the formation of condensation water in the control cabinet when using control cabinets in unheated environments, especially outdoors. The Dr. Neumann Peltier-Technik air conditioning units can easily switch between cooling and heating mode, thus ensuring a constant temperature inside the control cabinet. But even without switching to heating mode, you can use our Peltier control cabinet coolers thanks to our patented drain device without worrying about condensation inside the control cabinet.

Especially in the field of automated production, modern production plants increasingly require the installation of switch cabinets at locations with changing orientation, such as on robot arms or other moving parts. This is only possible with Peltier cooling units, because they can be installed in any position and still allow a reliable and direct cooling of the switch cabinet.
