Filterfan 4.0 New Video

/in , , /by

Trust in the Original

Otto Pfannenberg’s invention of the Filterfan® in 1958 was a milestone in the area of industrial thermal management. From generation to generation, our world-class engineers have been working on the continuous technological development of Pfannenberg Filterfan® products. Numerous improvements are continuously made including several breakthroughs, so valuable that they required international patents. All in all our Filterfans 4.0™ contain 11 field-proven patented features!

Discover below our New Video presenting the great features of our Filterfans 4.0™ line: quick and easy to install, to maintain or to replace and still no tools are required!

Important for the use of Filterfans®:

  • Use Filterfans® to force the surrounding air into the electrical enclosure, so that a slight overpressure builds up inside the enclosure.
  • The surrounding air enters the electrical cabinet exclusively via the Filterfans®, which ensures that it is filtered.
  • Install the Filterfans® in the lower third of the electrical enclosure and the exhaust filter as close to the top as possible. This assists the natural convection of the air and avoids hot spots within the enclosure.

Is your enclosure located in a wash-down area? Then Pfannenberg’s Rainhoods are your to-go choice! Their direct spray barrier and high air-flow baffle allow for superior protection from overspray entering the cabinet while minimizing airflow loss, more info here!

Pfannenberg Filterfans® to Cool the Control Cabinets for a 50 MW Photovoltaic Plant in the Philippines

/in /by

PROinSENER ENERGÍA. Cooling the control cabinets for a 50 MW photovoltaic plant in the Philippines.

The application

A 50 megawatt solar power plant was built in Palo, Leyte Island, and linked to the power grid of the National Grid Corporation of the Philippines in March 2016.

It is the second solar farm built in Eastern Visayas after the one in Ormoc City. Now, with three power sources of NGCP in Leyte, together with the geothermal plant at Tongonan in Kananga town of Leyte, there is enough providers for the energy needs of Leyte and Cebu.

The new solar plant consists of 188,000 solar panels built on a 70 hectar property located about eight kilometers inward from the main highway.

The customer

PROinSENER ENERGÍA is a Spanish provider for containerized solutions They design and manufacture transformer stations, solar inverted stations, electrical rooms, electrical panels and other containerized solutions for different applications: renewable energy, mining, water pumping stations, emergency units, etc.

PROinSENER has more than 400 MW installed worldwide, from the Philippines to Chile, with projects in Jordan, Morocco, Brazil, etc.

Our solution

PROinSENER has supplied 15 inverter stations in 40’HC containers. Each of them generates 2.8 MW for the 50 MW PV plant in Leyte Island. Philippines. Each control cabinet in these stations is provided with Pfannenberg’s  4th Generations Filterfans.

After evaluating different options on the market, PROinSENER’s choice fell on Pfannenberg’s original filterfans. When it comes to safe and cost-effective cooling of control cabinets with filtered ambient air, our filterfans are the first choice. Since Otto Pfannenberg invented it in 1958, they have held a leading position in the market.

The latest generation is even expanding this lead – with no fewer than 11  patent protected features as for example the closed housing, which reaches guaranteed high system of protection IP 54 and IP 55, or the fluted filter mat which, in the IP 55 model, keeps the volume flow constantly high but increases the service life (time between 2 mat changes) by 300 %.

Our εCOOL series sets standards in terms of capacity, cost-efficiency and maintenance friendliness.

The Technology of Cooling Part 1: Cooling with Filterfans®

/in , , /by

If the installation is in a clean, non-hazardous environment with an acceptable ambient (outside the enclosure) temperature range, a simple forced-air cooling system utilizing outside air is usually adequate. Combined with an air filter, such devices generally meet the heat removal needs of typical electronic equipment and many electrical applications. 

How do I know if a Filterfan® is the right product for my application?

  • If the temperature rise inside the enclosure can be higher than the ambient
  • If multiple configurations are needed. Filterfans® can be located in a number of locations within complex enclosure configurations.

Calculating the required airflow

To properly size a Filterfan® it’s important to understand how static pressure effects the performance of a fan.

Understanding CFM

CMF describes the volume flow rate of compressed air. We can define 3 different CFM:

  • CFM1: Fan Only (unfiltered)
  • CFM2: Filterfan® Assembly (uninstalled)
  • CFM3: Filterfan® Installed on an enclosure with one filtered exhaust assembly
    (Note: Always calculate cooling capacity of Filterfans® with the CFM3 value)

Utilizing Filterfans® for Enclosure Cooling 

  • Always use the Filterfans® to propel the cool ambient air into enclosure.
  • Slight positive pressure builds up inside the cabinet so that only air filtered by the Filterfans® flows into the enclosure.
  • The air propelled into the cabinet displaces the warm air which exits through the exhaust filter.
  • When installing a combination of Filterfans® and exhaust filters, fit the Filterfans® in the lower third of the cabinet and the exhaust filter(s) near the top of the cabinet.

Utilization examples

CFM : Filterfan® + Exhaust Filter CFM : Filterfan® + 2 Exhaust Filters CFM : Filterfan® + intake + Filterfan® Exhaust

 

Part 1 of our Thermal Management Solutions, Pfannenberg’s Filterfans® incorporate modern louvers which enable maximal airflow, hold back dust/flour and water particles, protect the filter medium from damage and can be integrated into the design of the application. Filterfans are an ideal cooling solution when the ambient air is always lower than the temperature required in the electrical enclosure. This assists the natural convection of the air and avoids hot spots withing the enclosure.

Selecting the Proper Equipment for Food and Beverage Applications

/in , , , , , , , /by

Proper thermal management is key for saving resources and keeping electronics (and equipment) up and running on a consistent basis. It is important to understand the various types of cooling methods available and how the ambient conditions may effect the product chosen.  Choosing the wrong method may lead to a solution that is undersized or oversized, or fails prematurely due to being specified for incompatible ambient conditions.

How to Choose the Proper Enclosure Cooling Product

/in , , , /by

Reliable Thermal Management:

Understanding the proper thermal management of your electrical enclosures is critical in keeping your production process up and running. Trouble-free production is only guaranteed if the sensitive climate inside your electrical enclosures is maintained, even the slightest overheating of the electronic component units can result in serious consequences such as production downtime and premature aging of parts. It’s important that you choose the proper enclosure cooling

Choosing the Best Solution for Enclosures and Electronics Cooling:

Before choosing the best cooling solution you need to know your environment. Is the control cabinet placement in an environment where the air is full of dust or oil? Is the equipment to be cooled exposed to the weather, i.e. moisture and sunshine? How large are the designated dimensions of the required cooling units? Once these questions have been clarified completely, you can move on to choosing the best cooling solution for your application.

Common Thermal Management Products:


FilterFans®

  • If the ambient temperature is always lower than the temperature required in the electrical enclosure, then  Filterfans® represent an economical solution for thermal management of electrical enclosures.


Enclosure Air Conditioner

  • If cooling cannot be accomplished by the outside air
  • If the temperature required inside the electrical cabinet should be equal to or lower than the ambient temperature
  • If the ambient air is strongly contaminated with oil or conductive dusts
  • When higher ingress protection is required (Type rating)


Air to Water Heat Exchanger

  • If a chilled water supply is available
  • If aggressive ambient air restricts the use of conventional cooling units
  • If a very high IP class is required (up to IP 65)
  • If a maintenance-free cooling unit  is required
  • If energy efficiency is considered at a plant level concern
