Preventing Condensation in Electrical Enclosures

/in , /by

Condensation is the act of a substance transitioning from its gas form to its liquid form. Condensation is a common phenomenon in nature, and we have all seen condensation of water on a bathroom mirror or on the surface of a glass holding a cold drink. Condensation occurs when the temperature of a surface drops below the dewpoint temperature – a dynamic, not static, temperature point that depends upon the interplay between humidity and ambient temperature.

While condensation may look beautiful in the form of the morning dew, it can wreak havoc with valuable electronic equipment. This moisture can cause rust, corrosion, short circuiting and electric shock – proving at the least to be expensive and at the most to be dangerous.

How to prevent condensation in Electrical Cabinets?

Pfannenberg, which specializes in providing solutions for thermal management systems, has its finger on the pulse of how to prevent condensation in enclosures – such as electrical cabinets – that need to be kept free of moisture.

The first tip has to do with controlling the enclosure temperature. “Traditionally, in an enclosure, we are going to recommend keeping the temperature somewhere between the 85-degree and 95-degree Fahrenheit mark,” says Pfannenberg sales representative Adam Wells. “That generally represents a comfortable place for the electronics as well as for keeping it warm enough to avoid that dew point temperature.”

Pfannenberg experts also recommend using dehumidifiers in enclosures with high humidity or that are not completely sealed to prevent condensation. Typical dehumidifiers use a desiccant or some type of silica gel to wick moisture out of the air. Air conditioning units can also act to collect any condensate that may build up on the internal side of an enclosure and be dispersed into the environment with the help of a condensate evaporator.

Hygrostat FLZ 600

An unusual device known as a hygrostat can also be used to monitor the humidity levels in an enclosure. Originally made of horsehair, hygrostats are now made with synthetic hairs that expand and contract depending on the amount of water in the air. The same can be seen happening in human hair – for example when hair gets curlier on a humid day.

Another way to open the door to condensation is, literally, by opening a door. Pfannenberg sales representative Chris Marlow explains, “If you have an enclosure, and you have a cooling device in there, and you don’t turn off the device when you open the doors, you can get condensation build up inside that enclosure just from exposing air to that decrease in temperature.”

PY L-S LED New Signaling Device to Assist in the Detection of Possible COVID-19 Infections

/in , /by

This device is ideal for a combined use with thermal imaging to convey normal and irregular activity

As more and more organizations return to business as usual – or as close as is possible – in the next phase of the COVID-19 global health crisis, new health and safety measures are critically important. In many settings, from office buildings and commercial centers to schools and medical offices, infection detection technologies are a necessary component of safe reopening.

One such infection detection technology option is that of skin temperature sensing systems. Composed of a thermal imaging camera, computer or other control device, and, often, a signal for flagging elevated temperatures, these systems can help to identify individuals with elevated skin surface temperatures for further health screening. In doing so, the system is part of strategies for ensuring infection containment and community health and safety.

Pfannenberg has developed the PYRA L-S color changing LED visual signal alarm with four selectable colors, part of the PYRA product family, is an ideal addition to skin surface temperature monitoring systems for real-time people flow control and COVID-19 monitoring. In these systems, the signaling device can be incorporated to convey normal and irregular activity to alert operators to alarm conditions so that suitable next steps can be undertaken.

Useful in manufacturing facilities, office buildings, commercial centers, schools, medical centers, and many other settings, such monitoring systems can aid in ensuring infection containment and community health and safety through its color changing blinking and flashing mechanism.

The PY L-S LED Visual Signal Alarm offers flexible, ultra-bright, color changing or single-color LED technology in four selectable colors and three selectable signaling modes. It can be surface or flush-panel mounted, and is a suitable, easy-to-install replacement for stack tower lights. Its IP 66-rated enclosure makes it suitable for use in all weather conditions, and for withstanding hose-directed spray during wash-down procedures.

“With this kind of access control systems, which generally have to be retrofitted, it is important to make handling as simple, efficient and cost-effective as possible for users,” says Volker Matthies, Director Global Product Management Signaling Technology at Pfannenberg. “On the other hand, the solution must work precisely and safely to ensure the health of employees and customers on site.”
