Tier 4 axial fans featuring the PressureMAX, sickle and airfoil blade profiles
Multi-Wing America has been working in the industrial heat exchanger markets since we opened our doors in 1972, and that hands-on experience is why our customers rely on Multi-Wing in addressing their air moving needs for Tier 4 emissions compliance. Tier 4 emissions requirements have brought significant challenges for our partners in engine power units, buses and motor coaches, and a wide range of off-highway applications. Multi-Wing’s Tier 4 emissions strategy for axial fans combines our custom design capabilities with products engineered for these demanding performance requirements. And using the combination of Multi-Wing’s innovation process and vital input from our partners in the off-highway diesel engine markets, our new PressureMAX blade profile is specifically designed as a Tier 4 cooling package solution.
- PressureMAX blade profile
- Sickle fan blades
- Low noise fans
- High efficiency fans
- Airfoil fan blades
- Engine cooling and radiator fans
The Tier 4 emissions standards call for stringent reductions in particulate matter (PM) and nitrogen oxide (NOx) levels, resulting in unprecedented challenges for cooling packages. Multi-Wing has the broad product range necessary to customize axial fans for Tier 4’s high heat rejection requirements. Our airfoil and sickle axial fans have the narrow axial depth necessary to accommodate the limited cooling envelopes created by reduced installation space in engine compartments. And our sales engineering staff can design a high efficiency, low noise fan that will save money in fuel consumption while reducing decibel levels in compliance with the Occupational Safety & Health Administration’s (OSHA) Noise and Hearing Conservation Standards for workplace noise. Multi-Wing can also customize durable, lightweight nylon fans that reduce wear on mechanical drive systems and water pumps, eliminating failures and resulting down time.
Under the EPA’s Tier 4 Requirements for Non-Road Mobile Diesel Engines, Tier 4 final in 2015 will result in particulate matter (PM) and nitrogen oxide (NOx) levels near zero. An expert at a 2010 Tier 4 emissions seminar drove the point home by saying, “Engine’s will have cleaner air coming out, than they will have going in.” While engine manufacturers have various combinations of emission technologies to choose from including exhaust gas recirculation (EGR), diesel particulate filters (DPF), selective catalytic reduction (SCR), diesel oxidation catalyst (DOC) and high pressure common rail fuel systems (HPCR), a custom designed axial fan is still a vital component of any Tier 4 emissions strategy. As one of Multi-Wing America’s heat exchanger partners said, “Outside of the core, the fan is the most important component in the cooling package.”
