Hydro engine fan shrouds increase air flow for improved engine cooling

The engines used in both light- and heavy-duty trucks, as well as construction equipment, generate an enormous amount of heat. Improving something as simple as an engine fan shroud to increase airflow can make a significant impact on engine life and operating efficiency. The traditional approach has been to attach a plastic fan shroud to the radiator, but this requires an opening much larger than the fan to avoid interference due to relative motion. The result is air pressure loss at the fan tips and reduced airflow to the engine.

Hydro worked closely with its customers to produce an aluminum fan shroud that mounts directly to the engine block, like the fan, (more)
