ComparisonFULL FLOORDARMANI CROSS AIR
Static Pressure High - Air is forced from the bottom. Substantially reduced as air has @ 6' less to push as cross air is suspended.
Air Restrictions High - Air is restricted by having to force air through small holes leaving only 17% open area. Zero - All the air is blown out.
Air movement (air travels path of least resistance) Good - Full floor is better than square pits in that it reaches outsides better having perforated material to the ends. Excellent - Cross air is designed to have the air blow evenly on all sides of the bin.
Centre core air movement Good - Full floor aeration allows air to move in all directions. Excellent - With optional cross air tower, the air travelling through the center core and up the center is greatly increased.
Fines/build up
Re-assembly
Problem - At some point in bins life, fines/build up occurs causing air to force fines into floor filling up underneath blocking air flow. This has to be disassembled, cleaned and then reassembled. No problems - never have to reassemble.
Ice/snow build up concern Potential Problem - Center clump build up can cause centre unload gearbox to jam leaving bin unable to be centre unloaded. No problems - As centre is covered with galvanized material, big clumps can't build up.
Cleanout Good - When purchased with a center cleanout system, all customer needs is a broom. Good - Cross air is raised so when purchased with unload system, all customer needs is a broom.
Bin access Hard - Bins with full floor have panels that have to be removed prior to access. Easy - Darmani bin features easy access door with vertical lift chute.
Foundation required Full floor aeration only works with concrete. Cross air works on both steel floor or concrete foundations.
