In cooling storage system, the grain cooler is not enough to keep the low temperature condition inside the silo, the cool energy could be lost within a few days, we must insulate the silo and that's why Alminco has developed insulation system. After time to time, Alminco keeps improved the insulation and obtain the patent. However, Alminco has given-up the patent and allow everyone using it on their silos, we feel proud of the way we are doing it because we believe this technology should bring benefits to all the users. The silo insulation has an bonus, the user can use the same color like the factory or put the logos and names on the insulation sidewall, it has excellent effect to use as an commercial advertisement.
 

There are 3 parts of silo that should be taking care of, the roof, the sidewall, and the bottom. For the round silo, Alminco use PU spraying under the roof sheets for insulation (left photo). For the rectangular bins, because it has the insulation sheets on the top of bins (right photo), so there is no need to use PU anymore.
 

The sidewall should be covered by insulation sheets, for the round silo, it needs to add extra frames so the insulation sheets can be screwed on the frames, the it helps the structure of sidewall to be more stronger.
 

The sidewall of rectangular bins has frames already, so the insulation sheets can be screwed on directly.
 

Only the hopper bins need to do the insulation. Alminco use special PU to spray on the hopper, and it would be better if the ducting can be covered by PU also.
