This is good news for any environment e.g. conference and presentation spaces, theatres, concert halls, lectures theatres, interactive AV displays, boardrooms and demonstration facilities, etc. utilizing AV equipment where noise is a potential issue, distraction or annoyance, says the company.
Penn's R 'n' D team has pooled its considerable experience and practical knowledge of the racking market and produced an ultimate and well-engineered solution.
The versatile FP02-Q-3U fan unit emits 22.5 dB(A) - with a Sone (loudness) value of 0.3 - and can be fitted to any existing 19 inch racking unlit. At the top is the optimum position as the heat rises and will be extracted most efficiently.
The two 9-bladed fans measure 120 mm, 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 C and will re-set at 30 degrees C plus or minus 2 degrees.
Using a neat acrylic adhesive pad, the sensor can be attached to an area where it will best detect the overall ambient temperature of the equipment being cooled - rather than directly to the main heat source.
The lifespan of the Swiss-designed fans has been further extended - by at least five times that of a standard fan - with the use of robust Japanese dual ball-bearing brushes and high precision lubricants, which facilitates continuous rotation 24/7 with no compromises.
Dust, smoke / fog, other detritus, high temperatures and other contamination has less effect than when using standard bearings, so the product is super-reliable and ideal for 'fit-and-forget' scenarios and installations.
