IBC tank venting set

We always recommend venting IBC containers! But especially when IBC tanks are stacked and connected by a tank connection set, venting of the container below is advisable.

But why do I need a vent for stacked IBC tanks? - We enlighten you!

1. If you stack several IBC tanks and connect them with each other, the lid of the IBC below must in any case be sealed water- or air-tight! If this is not the case, as soon as the maximum filling level has been reached, the water will leak through the lid at the top of the IBC. This case also occurs with vented lids, since water can escape from the vent as well as air.

2. If the lid on the IBC container is now closed watertight or airtight, the air is consequently held in the IBC inner container and a counterpressure is formed to the inflowing water. When the two stacked IBC tanks are connected to each other via the valves attached to the tap, the inflowing water prevents the air from escaping from the tank connection.

As the process continues, the internal pressure of the air bubble of the lower IBC container becomes at least as great as the water pressure of the inflowing water. Therefore no more water can flow in afterwards and the lower tank can be damaged.

The solution: Our tank venting set!

You mount a tank feedthrough at the top of the lower IBC container and connect a vent hose to it with the help of a cable tie. You attach the hose to the upper IBC tank (see illustration!). By mounting the venting hose, the air can escape first.

If the maximum filling level is now reached in the lower IBC container, the water in the hose starts to rise. Thus, you can fill both IBC tanks to the maximum without any problems.
