Hydraulic Shutters

Automatic radiator shutters are designed to eliminate overcooling and avoid overheating by regulating the amount of ambient airflow through the radiator.

 

Louvers (also called dampers or shutters) open and close based on a specific trigger, eliminating both overcooling and overheating by regulating the amount of ambient airflow through the generator engine's radiator. Louvers can be thermostat activated, in which case a thermostat is installed inside the generator enclosure and an electronic switch triggers their operation when temperatures rise above a preset threshold. Electronic louvers such as these should always include electronic stall protection. 

 

Louvers can also be hydraulic, being driven directly by the temperature of the engine's coolant. Coolant-driven louvers open gradually, allowing the engine to cool effectively but preventing a sudden influx of cold air that could cause the temperature inside the generator enclosure to drop precipitously. 

 

Hydraulic louvers are a preferred option in extremely cold climates because they do not contain sensitive electronic parts that are prone to seizing and failing in cold weather. Both types of louvers should also be able to prevent snow intrusion into the unit.

 

There are two configurations available. The electric version opens and closes in response to a thermostat installed inside the generator enclosure, the hydraulic version shutters open and close in response to changes in engine coolant temperature and help to maintain optimum engine operating temperatures—all while improving engine performance, durability, and fuel consumption.  Maintaining optimum engine operating temperature results in up to 1.5% improved fuel consumption and longer oil life and provides a quicker interior heat during cold weather operations occurs by the shutter regulated ambient airflow through the radiator.
