Mitzvah present importance of air curtains in warehouses

Warehouses are crucial pieces of logistical equipment. Almost all of the things you buy everyday pass through a warehouse at some point. These items are often carried by truck through a loading dock. These cargo docks feature big doors that are always open. When these doors are opened, the outside climate may wreak havoc on the warehouses inside. Warehouse managers may struggle to regulate the internal temperature of a warehouse because the flow of air can drastically change the temperature inside. Using air curtains is a simple approach for warehouse managers to stay ahead of the competition.
