LOADTEC VAPOUR RECOVERY LOADING ARMS are designed to capture the vapours displaced from the road tanker or rail tanker, during filling operations.

The most common method for collection of vapours during filling, is via a cone shaped plug that closes the open manhole and diverts the vapours back to the loading rack. This could be via a hose, piggybacked onto the liquid arm or via a separate parallel arm.

Alternative methods of vapour recovery can be supplied using two separate loading arms, one for filling and one for vapour return, connected to the  tanker via a flange or coupling. The latter is mainly used when the liquid being loaded has high toxicity.
