The demands on engine cooling systems have risen dramatically over the past two decades. Factors that have driven this rising demand are an increase in the number of fluids that need cooling, a push for higher power output, and the implementation of stricter emissions regulations.
As both initial capital costs and operating costs continue to increase for cooling systems, so has the awareness of the importance of properly optimizing these systems. Cooling system designers must ensure that engines do not overheat during peak ambient conditions when running at full power, while considering the cost and parasitic power lost to the cooling system.
Flexxaire produces variable pitch fan systems that provide total airflow control, allowing cooling system designers to meet the cooling requirements of peak ambient conditions in addition to minimizing the parasitic losses inherent to standard cooling fans.
