Safest Way to Cool with Water

/in , , ,

Electronics Cooling with an Air to Water Heat Exchanger

Water is the most efficient form of heat removal. Using an air to water heat exchanger allows you to safely cool your electronics using water, while also keeping external contaminants from entering your enclosure. Air to water heat exchangers also offer the advantage of being low maintenance while using significantly less energy than traditional methods.

Advantages of Pfannenberg’s Air to Water Heat Exchangers:

How do we safely cool with water?

#1: Bulkhead fitting for condensate drain providing superior ingress protection.
#2: Solenoid valve – controls liquid flow for capacity control and energy conservation.
#3: Color-coded water lines easily identify water supply & return lines.
#4: Air flow path designed to prevent condensate water from entering the enclosure.
#5: Internal design guarantees  full separation of water lines from airflow paths.
#6: Electronic thermostat for more accurate control of temperatures. Manual purge feature eases winterization.
#7: One-piece cover with sloped top for better protection of internal components and easy cleaning in wash-down applications (not pictured).

CONCLUSION:

Water has been used for years around sensitive electronics.  There’s no reason to be afraid of using water to cool your electronics. This is a great option to consider when your looking for safe and efficient solution to manage your cooling.

Pfannenberg Illuminates the Tallest Christmas Tree in Paris

Flashing lights make the “Place de la Concorde” shine

Hamburg, December 2012 – The tallest Christmas tree in Paris, which stands at 35 metres high, has been shining at the Place de la Concorde since the 6th December.

Equipped and illuminated with Pfannenberg 52 Quadro F12 flashing lights and inaugurated in an official opening ceremony by Paris’ mayor, Betrand Delanoë, the extraordinary light spectacle can be admired by inhabitants and visitors for a whole month longer.

Once again, Pfannenberg has proven that it is a competent partner in terms of art illuminations. As early as 2003, 20,000 Pfannenberg flashlights put the Paris landmark, the Eiffel Tower spectacularly in the limelight. Pfannenberg as a Hamburg company it was an absolute must to illuminate the Hamburg City Hall in 2004. And in 2008 9,500 flashing lights illuminated the Trinity Bridge, the television tower and the summer night sky in St. Petersburg.The French company SAF MAGNUM was commissioned by the City of Paris and is thus responsible for the Parisian Christmas Tree illuminations. The company is, amongst other things, a specialist for the illumination of events. Whilst searching for a manufacturer of flashing light circuit boards, SAF MAGNUM encountered the Quadro flashing light used in the Parisian Eiffel Tower which was produced by Pfannenberg. SAF MAGNUM then used this to build a prototype for the Paris Christmas tree.

For the flashing lights on the Christmas tree the circuit boards of the flashing light Quadro F12 were built into a plastic ball with a diameter of 50 cm. The ball is then, in addition, illuminated permanently from the inside by 12 red high-performance LEDs. The red permanent glow of the balls is made to sparkle by the Pfannenberg flash circuit board by means of a white flash once every second. This light generates 13 joules flash energy, 140 candela light intensity and an internal random generator creates a unique champagne pearl effect.
