“We had 16 new 24,000 bu hoopper bins put up with the recommended aeration in 2015, and when we filled them all the aeration collapsed in all 16 bins, we were very unhappy.

Then one day I was reading the Western Producer and saw an article about a new air system called CrossFlow Aeration and it described how columns ran up the sidewalls and moved air to a center release point; we became very interested.

So I contacted the inventor, Gary Schreiner, and he explained to me that columns run up the side walls up to 60% of the height of the bin and a center tube would come down 24 feet and be tethered to the center of the bin. We decided to buy 2 CrossFlow systems and had them installed in the summer of 2016.

After using the CrossFlow in 2 of the 24,000 bu hopper bins 2016 we were convinced, and found out that this system was truly amazing and does dry and cool grain very quickly.

We also noticed that we have no grain crusting on the interior walls of the grain bins anymore because these columns leave air out of the front and sides of each column and push air along the side walls of the bin and up to the eves, we were very impressed.

In 2017 we had all the other 14 bins converted over to CrossFlow and now put any type of grain in these huge bins, like canola, and never worry anymore.

“Yes it is a bit more money! You get what you pay for! This aeration system is more efficient & effective, it just gives peace of mind during and after harvest.

We totally depend of this crossflow system for our straight cut canola program, we put canola in at 12-14% moisture and dry it down, crossflow completes the straight cut canola program.

We invest a pile of money to grow and protect a crop every year, with little control over the weather or markets. More often than not we have to hold commodities to extract a profit, and with crossflow aeration we can do just that and have peace of mind storage.”

“I had 2 bins of wheat, both flat bottoms, one was 7500 bu with crossflow aeration which I filled with 19.5% wheat, in one week it dried down to 14.5% moisture!At the same time, I filled another bin, 5000 bu with floor aeration, with 17.5% wheat. After 2 weeks it only dried down to 15.5% moisture, and then it wouldn’t dry down anymore, so I moved the wheat to the bin with crossflow and then it dried quickly.

I also had a 12,000 bu bin filled with corn at 25% moisture. I put a heater on the crossflow aeration system, and in 11 days it was down to 14.5%! Drying corn in a bin with crossflow using a diesel fuel heater is cheaper than cunning it through a grain dryer.

After these amazing crossflow results, I put up two 20,000 bu flat bottom bins with crossflow, it’s the only aeration I will install in a bin now.

During a phone call from Gary the farmer who invented crossflow, he started saying, “if I tell people how well it actually works…..” and I finished for him, “people wouldn’t believe that it could work that well, because it sounds too good to be true”, but it is true, it works as well as he says it does, and more.”

We tried the GrainAir Tubes in 2011 with a 5,000 bu. bin of canola. On September 20 we put the canola in the bin at about 42°C (108°F). We left the lid open and let the Tubes cool the bin and when we unloaded the bin December 20 the temperature had dropped to about 17°C (63°F).

It was a warm harvest this year and we had to take some canola off the field hot. We put canola that was about 40°C (104°F) in the bin during early September to let the GrainAir Tube cool it. We kept a pretty close eye on the bin but it cooled off really nice and we didn’t have to turn it or do any work at all. I was surprised and pleased when we hauled our canola in late December and it had cooled down to 15°C (59°F)!

We have a bin of corn gluten meal that has been an absolute nightmare for years. We constantly had issues that required us to break up the clumping and bridging that took place in the bin, even when it was cool. We decided to try a GrainAir Tube in 2010 and have been blown away at the difference. The corn gluten meal is flowing perfectly. The GrainAir Tube has saved us countless hours of work and waste. It is, by far, the best $1,000 we have ever spent.

Perfect corn thanks to GrainAir Tubes!

I have been using the Grain Air Tubes for about three years and have been very happy with them. They don’t dry the grain down all the way, we usually get about one or two points out, but what they do extremely well is cool and keep our bins. I use the Grain Air Tubes to store my canola and it comes out of the bin just the same as the day it went in, and my canola was perfect from top to bottom. I recommend the Grain Air Tubes and plan on buying more.

I bought some Grain Air Tubes in 2008 and tried one tube in a bin of flax. I had another bin of flax right beside it that was heating and needed to be cleaned out. I went to clean the bin with the Grain Air Tube but the flax was cool and running extremely smoothly so I didn’t need to clean it out. Now I use the Grain Air Tube in my canola bins and I don’t even need to check them. With the Grain Air Tube cooling my canola, I can sleep at night.

I decided to try out a Grain Air Tube in 2010 and wanted to see how well it would work. I filled two 6,000 bushel bins with wheat, one with the Grain Air Tube and one without, in late August when the temperature outside was about 80°F (27°C). A month later I probed the bins to check the temperature. The temperature outside was 60°F (16°C) and I found the bin with the Grain Air Tube was already down to 45°F (7°C) but the bin without the tube was 85°F (29°C). The Grain Air Tube had cooled the wheat by 40°F (22°C) in only a month!

I have a 10,000 bu granary with a Schreiner Grain Air Tube, & it cooled down very nicely; no problems with bugs, my smaller 5000 bu bins without pipes have bugs…

We have two 150’x50’ Quonsets that we use for grain storage, we put in warm grain & the tubes helped cool it down very well; we are very pleased in how the tubes performed with cooling down our grain.

I have been a customer for 3 years & return to buy a few tubes every year; very happy with how it cools grain, keeping my wheat & peas in good condition.

I was very happy using Schreiner Grain Air Tubes, very impressed in how it cooled the grain, & simply amazed when it dried the grain down from 16 to 13.5

…52,000 bu grain in a Quonset, 5 air tubes with temperature sensor cables beside the tubes, records showed temperature declined 2 degrees every 5 days; very happy…

Late last fall [2008], I stored 8000 bu malt barley at approximately 15.5% moisture; the next summer, the barley came out dry at 13.5% and sold for malting. I was amazed and extremely happy with the cooling & drying results.

I installed air tubes in some of my bins in August 2008 as a trial. On February 1st 2009, I did bin checks on the 4100 bushel bins filled with canola using a standard laser gun. The bins where air tubes had been installed registered 3 to 5 degrees C cooler than the bin where no air tube had been installed.

The other thing of note was the paper thin layer of ice at the top of the bins with air tubes versus no crust of ice on top of the canola in the other bin. This was proof that the grain was breathing. I am convinced that this is a very feasible and economical safety measure for grain storage enhancement, and intend to install the air tubes in all of my bins.

We piled 750 ton of barley 16 feet high in a poll barn in the middle of harvest, the air vented through the shed naturally with grain air tubes, and by the end of October it had cooled down. It was then removed in Jan / Feb in good condition. I would recommend grain air tubes to anyone as an effective way of cooling down grain.
