Switch cabinet dehumidifier: Switching and control

Nowadays, technology has reached a point where the necessary hardware can be reduced to a minimum – and still fill an entire cabinet. Do you also have a control cabinet in your company, on your company premises, in your production or in your office? Then you face several challenges. The technology in the control cabinet is sometimes so sensitive that even the slightest fluctuations in temperature or contamination could cause a total failure. Temperature in particular is a major concern.

Some like it hot. Some don’t.

Wherever a lot of technology is in operation, heat is generated, and in most cases even heat. This is partly due to the law of conservation of energy in physics and the metals used in the electronic parts. In a switch cabinet, energy flows without end – after all, this is where the most complex processes are coordinated and controlled. Unfortunately, however, the energy used is not 100% and exclusively for the intended purpose – a small part of the energy evaporates from the process in the form of heat energy. This circumstance is almost unavoidable.

Metal not only conducts electricity well, but also heat. These two facts in combination naturally favour a rise in temperature in the switch cabinet. In addition, the door should always be kept closed, because external influences on the extensive systems should be avoided if possible. After all, everything in a control cabinet has its strict order and a fixed concept. Even dirt or small flying insects are undesirable in control cabinets. When the door is closed, i.e. no draught, the natural air cooling that works in everyday life with smaller electrical appliances is therefore not required. The solution is an effective and well thought-out cooling system. If this is not available or poorly installed, there is a danger that is always underestimated: condensation water.

Switch cabinet humidity

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.

With an air conditioning system from Dr. Neumann Peltier-Technik, you are assured of a comprehensive solution for your switchgear cabinet. Cooling, ventilation, dehumidification. Rely on a proven principle combined with years of experience from a team of competent specialists. We take care of your problem and offer you a customized concept.

The Peltier Technology

All our systems for cooling and heating are based on Peltier technology. This is a very proven and safe system whose temperature control effect is easy to control. The big advantage is the structure of the Peltier plates. With one direction of current flow side A heats up, side B cools down. If the direction of current flow is reversed, exactly the opposite happens on sides A and B.

This effect can be reversed within a few seconds, is easy to control and can be installed in almost any format. Thus, Peltier technology is a well suited basis for our products – so well, in fact, that it has been given a part in our company name.

The effective control cabinet dehumidification

The switch cabinet dehumidifier patented by Dr. Neumann Peltier-Technik not only provides support for the temperature control of your switch cabinet, but also offers an effective dehumidification system with safety features.

The basic element of the dehumidifier is a ventilation-free Peltier cooling plate, which is located inside the switch cabinet after installation. It collects any condensate that has formed in the switchboard. The droplets flow out of the cabinet interior via a safe pipe and thus no longer pose a danger to the sensitive high-performance components. The cooling plate is equipped with an intelligent temperature sensor system to prevent the collected condensate droplets from freezing. Depending on the size of the control cabinet, several of these modules can be synchronized to achieve an optimum result and keep the control cabinet dry.

Keep the cabinet cool

Control cabinet Moisture can also be combated when it is already too late – please contact us for this. Of course, it is better to take preventive action, but even if you have already found moisture in your switch cabinet, it is worth installing a dehumidifier in the future to prevent worse from happening.

We at Dr. Neumann Peltier-Technik offer each customer maximum individual service. In this way, we work with you to find the perfect solution for your needs. From simple sketches, initial drafts and complex 3D models to the finished product – when designing your model, we pay great attention to every detail, because this is the only way to guarantee the greatest possible efficiency.

After all, this is what everyone wants – to offer perfect service.

Control cabinet dehumidifier, individual and genuine

Depending on your wishes and needs, a safe and reliable system will be designed for you. In doing so, we use existing products from our range and may complete the system with custom-made products. Because the demands of an electrical cabinet and its environment cannot be satisfied with a single, fixed range of products. Dr. Neumann Peltier-Technik products come from the greater Munich area and are therefore a quality product from the heart of Bavaria.

Switch cabinet dry – efficiency guaranteed.
