Storing Grain & Keeping it Dry

Storing grain to minimize loss due to moisture is a real-world problem for farmers and wholesalers. 360 products has created a patented passive ventilation system for storage containers that virtually eliminates condensation with only the power of the wind.

Below are the results of a real world field test conducted by John, a customer living near the Dallas, Texas area.  He stores one-ton pallets of grain in containers. Though the containers are directly on the ground, the grain sits on pallets and does not touch the floor. The purpose of the venting is to stop, or at least curtail the grain loss due to damage from moisture created by the container.

The figures below were recorded by John and sent to us as reference points. The numbers are consistent with others we have received from various parts of the country.  All have reported a substantial decrease in both heat buildup and humidity levels after installing our system. The remarks received from customes range from “very good” to “remarkable” and the overwhelming majority have reported that “container rain” is now a  thing of the past! 

John will continue to measure results as the season changes and we are grateful for his time investment. We will publish those results here as they become available.

Moisture Control Field Test Results

Early Spring 2019

  • Prior to installing  the 360 Passive vent system:
  • Outside container temp was 46 degrees F, 41% humidity
  • Inside container – 52 degrees F, 82% humidity
  • Note:  The humidity had reached as high as 93% inside the container

After installation of 360 passive vent system:

Measurement 1:
Outside container – 62 degrees, 78% humidity
Inside container – 74 degrees, 46% humidity

Measurement 2:
Outside container – 73 degrees, 77% humidity
Inside container – 89 degrees, 39% humidity

Measurement 3:
Outside container – 73 degrees, 86% humidity
Inside container – 76 degrees, 63% humidity

**Measurement 4:
Will be covered at the end of this testing report

Measurement 5:
Outside container 55 degrees, 99% humidity
Inside container 57 degrees, 69% humidity

Measurement 6:
Outside container – 68 degrees, 72% humidity
Inside container – 82 degrees, 39% humidity

Measurement 7:
Outside container – 53 degrees. 46% humidity
Inside container – 65 degrees, 43% humidity

**Notes:
Measurement 4 was taken on a day/night temperature swing of over 50 degrees (80+ degrees day and a drop to 30 at night) with very little noticeable wind present.  Some moisture formed on the top inside edges of the ceiling. This is the worst case scenario for all passive vents. None will perform well in this condition although the360 system will continue to create a minor air exchange situation, regardless of outside wind velocity.  For those who need to address this extreme scenario we will be introducing a small, energy efficient fan kit that retrofits to use as a backup and expect to be able to provide them by Late May of 2019.  They will be for either solar or standard electrical power (for those who have it available and just want to run an extension cord) and be a simple installation utilizing the existing exhaust port.  It should take no more than a screwdriver to adapt it.  More on that as we finalize specifications and pricing.

We hope this information is of use to you in looking at your own container situation.  This is an idea of what to expect given the variances of climate conditions that mother nature throws at us.  We also appreciate the feedback of our customers like John, and encourage you to contact us with your questions and concerns.
