• Amazing cooling results

    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).

  • Cooled canola from 40°C (104°)

    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)!

  • The Best Thousand Dollars We’ve Ever Spent

    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

    Perfect corn thanks to GrainAir Tubes!

  • My canola was perfect from top to bottom

    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 can sleep at night!

    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.

  • Cooled the wheat 40°F (22°C) in only a month!

    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!

  • No bugs

    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…

  • Very pleased

    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.

  • Repeat customer

    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.

  • Simply amazed

    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

  • Declined 2 degrees every 5 days

    …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…

  • Amazed and extremely 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.

  • Proof that the grain was breathing

    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.

  • Recommend grain air tubes to anyone

    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.
