Multi-Wing launches PressureMAX high pressure fan for Tier 4 engine cooling

Tuesday, March 22nd, 2011

Multi-Wing introduces the PressureMAX blade profile, a high pressure impeller designed specifically to help engine manufacturers meet the Tier 4/Stage III B Standards for off-highway diesel engine applications. The PressureMAX generates up to 20 percent more static pressure than standard airfoil fans. The PressureMAX also has virtually zero blade deflection, and its narrow axial depth makes it a perfect selection for tight installation spaces. Multi-Wing debuted the PressureMAX at the 2011 CONEXPO-ConAgg exhibition at the Las Vegas Convention Center.

Held tri-annually, the show is the epicenter of new technologies, products and services across the construction and agricultural markets, with more than 140,000 attendees. Multi-Wing held a special demonstration at the show, detailing the research and development process that led to the PressureMAX launch. Among the attendees for the demonstration, Matt Rankin, Engineering Manager for AKG Thermal Systems, was impressed with the PressureMAX features. “We’re always looking for any incremental gain that we can achieve for increased performance requirements in the mobile and compressed air markets,” said Rankin. “And the PressureMAX’s ability to deliver 20 percent more static pressure in a compact cooling envelope will give us just the edge we need in those markets.”

Designed to satisfy the high heat rejection requirements that result from Tier 4, the PressureMAX blade profile is also 5-7 percent more efficient than most airfoil blade designs, saving horsepower and fuel. The PressureMAX’s high efficiency profile also reduces air flow turbulence across the blade, resulting in a lower noise signature. With a diameter range of 24.5 to 51 inches , the adjustable pitch PressureMAX is a glass reinforced polyamide fan available in 5, 6, 7, 8, 9, 12 and 16-blade configurations.
