Global flightcase and loudspeaker component manufacturer Penn Elcom has launched a new, low-noise, 3U heat extraction unit, which can be fitted to the front or back of any 19-inch racking unit to quickly and silently suck the heat out of an enclosure.
The solution is expected to be of particular benefit to any environment where noise is a potential issue, distraction or annoyance, e.g. conference and presentation spaces, theatres, concert halls, lecture theatres, interactive AV displays, boardrooms and demonstration facilities utilising AV equipment.
The versatile FP02-Q-3U fan unit emits 22.5 dB(A) with a Sone (loudness) value of 0.3. It can be fitted to any existing 19 inch racking unit, ideally at the top, which is the optimum position as heat rises and can be extracted most efficiently.
The two nine-blade fans measure 120mm, and each fan unit can be controlled by a CRC-TEMP thermal sensor accessory plugged into the Temp socket on the front. This is set to operate at 40 degrees Celsius and will re-set at 30 degrees Celsius (plus or minus two degrees).
Using an acrylic adhesive pad, the sensor can be attached to whichever area it will best detect the overall ambient temperature of the equipment being cooled - rather than directly to the main heat source.
As with all Penn Elcom products, the heat extraction unit has been designed to last and withstand harsh operating conditions. The lifespan of the Swiss-designed fans has been further extended through the use of robust Japanese dual ball-bearing brushes and high precision lubricants.
This ensures that dust, smoke/fog, high temperatures and other contamination has less effect than when using standard bearings, making the product ideal for ‘fit-and-forget’ scenarios and installations.
