Environmental Protection


Mainly use to avoid foreign object to enter the turbine, screens are usually categorized between 3 categories:

Insect Screens: 

In areas where the swarming insect season is intense, a galvanized mesh outside the air inlet prevents insects to block the louver or load the filters too quickly. They are designed at an air flow that allows insects to fly away, facilitating the cleaning up.  If required by the site environment, they can also be design to be removed in the winter, to avoid snow or ice accumulation, thus pressure drop increase.

Bird Screens:

On the same principle as the insect screens, bird screens are built with a wider mesh.

Trash Screens:

Usually the larger mesh screen, trash screen can be location in the ducting, following the silencer, as a last protection against FOD (foreign object damage) to the turbine. 

Weather Protection:

Weather louvers and weather hoods are used to prevent entry from water (rain or sea water in offshore environment) and snow in the air inlet. Water entering the filter house can wet the filters and cause higher pressure drop and dirt over.

Weather louver, or droplet separator, are recommended on most air inlet. Available in PVC, Aluminum or SST, they can be heat traced in colder environment.  See our Camvane specifications.

Rain hoods are used to avoid over drainage on the louver, when water debit is over 4g/m per sqft.

Snow hoods can be used if there is a snow build up on the filter house. Larger than regular hoods, the lower air velocity prevents the flakes being entrain the inlet.
