Air Balance and Ventilation System

In non-climate controlled warehouses, the weather and its change can be the hidden enemy.  Due to the enormous cubic size of bulk warehousing, the effect of radical seasonal changes outside (i.e. dew point to pressure/temperature) will stratify air layers within the warehouse.  Stratification results in high eves temperatures, cool floor surface temperatures and mid-layer air temperatures between eves and floor.  The stratified layer will become moisture-laden and through uncontrolled circulation, it will move slowly downward towards the cooler surface air (i.e. concrete floor).

Once the moisture-laden air reaches the floor surface, it must be redirected or it will stagnate and the moisture will be released to the cooler surface.  This results in condensation.  If left unchecked, the condensation will transfer to the inventory and can result in costly damage.

Liberty, however, has turned a negative into a positive.  As you are aware, climate control can eliminate condensation.  However, costs associated with it can increase operational costs to a point where the economics would exceed normal budget limits for bulk warehousing.  Liberty contracted the service of a retired NASA engineer and jointly developed a system of "air balance and ventilation exchange" which virtually eliminates the danger of condensation damage to inventory. After several weeks of monitoring and testing the interior environment, the air balance and ventilation exchange system was designed and installed.  The resulting balance and exchange mixed the air, closed the temperature variables and eliminated the possibility of air stratification.  This was accomplished by strategically placing air balance systems throughout the warehouses.

Once in operation, the system utilizing in-line 27M CFM downdraft blowers would pull down warmer air from the eves and through a system of in-line ducts, distribute warm eves air across the floor at 3/4" static pressure.  This flow warms the floor surface and reduces eves-to-floor surface temperatures to +/- 7 degrees Fahrenheit.  When fully operational, the reduction of temperature variables prevent moisture from escaping from the air in the form of condensation.  To that end, LIBERTY WAREHOUSING, INC. brings a new meaning to "dry public warehousing".
