AMETEK Dynamic Fluid Solutions (DFS) is proud to launch the Nautilair® Enhanced 12.3" High Energy Brushless Blowers to provide hydronic system manufacturers a more powerful blower with up to a 14 db reduction in sound!
GET THREE TIMES MORE POWER AND ELIMINATE DEMAGNETIZATION WITH A NEODYMIUM MAGNET
AMETEK DFS upgraded the original Nautilair® 12.3" blowers from a Ferrite magnet to a Neodymium magnet, which offers three times more power.
You get all this power, plus Neodymium magnets also minimize the risk of demagnetization by outside magnetic fields or high temperatures.
INCREASE OVERALL EFFICIENCY AND REDUCE SOUND UP TO 14 dB AT TYPICAL OPERATING SPEEDS
AMETEK DFS replaced its original plastic cooling fan containing 20 straight blades with an aluminum fan which features only eight backward curve blades.
The new design can also incorporate an impact-resistant plastic cover with an exhaust tube as compared to the original metal powder coated enclosure without an exhaust tube.
These design upgrades increase overall efficiency and reduce sound. Here is how:
|ORIGINAL DESIGN||ENHANCED DESIGN|
|The metal enclosure exhausts the cooling air through a series of louvers radially using a radial fan with 20 straight blades.||The plastic enclosure exhausts the cooling air by scrolling it tangentially through an exhaust tube using a backward curved fan with only eight blades.|
|The exhaust louvers broadcast motor and fan noise radially outward and the multiple straight blades create more blade pass noise.||The backward curved cooling fan with
significantly less blades reduces noise as well as improves motor efficiency without compromising motor cooling.
|The motor exhaust louvers create the possibility of motor cooling air recirculation and elevating motor operating temperatures.||The motor exhaust tube prevents any recirculation of motor cooling air and provides customers with an option for ducting the air out of their system.|
LEVERAGE AMETEK DFS HYDRONIC SYSTEM BLOWER EXPERTISE
For decades, AMETEK DFS has been manufacturing Nautilair® brushless blowers for hydronic systems. We know that all water heater system designs are not the same. That is why AMETEK DFS also offers a professional service to optimize the Nautilair® Brushless Blower design within its customers’ systems to provide more power, less sound and greater efficiency.
