3 Solutions to Protect your Electrical Enclosures From Condensation and Humidity

/in , , , , , , ,

What is condensation?

Formation of condensation is one of the biggest dangers for electrical enclosures. Condensation is caused by hot, humid air coming into contact with a colder surface than the air dew point.

With Spring’s typical variable weather conditions, outdoor enclosures are even more exposed to the risk of condensation. Condensation can also occur indoors if the humidity is too high.

When the humidity is high is does not take a large change in temperature to cause condensate to form inside the cabinet.

How to prevent condensation?

The most efficient solution is to combine Filterfans® and Heaters with control devices such as Hygrostats and Thermostats. Fan Heaters are typically used in outdoor applications where ambient temperature can threaten sensitive electronics. Radiant Heaters are often used to reduce humidity and control condensate within the enclosure.

1. Filterfans® + Rainhoods

Filterfans® are the ideal solution for clean, non-hazardous environments with an acceptable ambient (outside the enclosure) temperature range.

Designed for use with standard Filterfans®, Pfannenberg’s new Rainhoods (Patent Pending) protect your application from harsh environments like rain, water spray, snow or fluids from being drawn into the enclosure.  This product feature a robust design rated to NEMA TYPE 3R/4/4x and IPx6 when used with Pfannenberg Filterfans®.

Adding a Heater to your Filterfan® + Rainhood solution will ensure a proper humidity control. This combination is the optimum solution for the economical and energy efficient cooling of electrical enclosure components.

2. Fan Heaters

Pfannenberg Heaters prevent condensate build up and therefore protect against corrosion.

The PRH-M Mini Radiant Heaters are ideal for small outdoor enclosures, preventing condensate formation.

The FLH Heaters are ideal for use in larger electrical enclosures.

3. Thermostats / Hygrostats

Pfannenberg’s Hygrostats allow you to effectively control the humidity level inside the enclosure. These devices are used to start the heater or filterfan® if the predetermined humidity threshold is reached.

When combining a Pfannenberg Thermostat with a Filterfan®, the fan can be controlled to turn on and off based on the temperature inside the cabinet.

The benefits to this combined system are:
• Extended fan life.
• Reduced energy consumption.
• Reduced consumables and maintenance.

As a system; Filterfans, Heaters, Thermostats and Hygrostats will ensure that the environment within the enclosure is ideal for the performance and service life of the critical electronics.

Pfannenberg – Global Solutions and Support for OEMS

/in , , , , , ,

When it comes down to the final decision on whether or not to purchase new equipment for a plant, the decision tends to fall down to three major concerns:

  1. What preventative yearly/monthly/weekly/daily maintenance is required?
  2. Is it able to withstand the environment?
  3. How much time and money will it save?

For OEMS to be competitve and meet the needs of their end use customers, there are 3 main areas that are looked at when choosing the supporting components for their equipment.

Control Enclosure Temperatures in a Food & Beverage Manufacturing Plant

/in , , , , ,

Controlling enclosure temperature is crucial in the food and beverage industry.  If the temperature is too warm or too cold, condensation and higher risks of contamination arises. 

Pfannenberg’s Heaters, Thermostats & Hygrostats detect and keep ambient conditions above dew point to avoid the harmful effects of condensation on your electronics and products. They can be used as standalone or in partnership with our other Thermal Management solutions specifically our Filterfan® and Cooling Unit product lines.

  • Thermostats are used for alarming, fan control and heater control
  • Hygrostats can control humidity levels within enclosure when used with small heaters
  • Heaters are available for cabinets in cold storage areas as well as for condensate management

For over 60 years, Pfannenberg has been helping to cool and maintain temperatures for your electronics.
