The offered system is a cost-effective and reliable solution for loading/unloading of liquefied hydrocarbon gases. Unlike dispensing hoses, rigid pipes help avoid breaking, sagging and condensate accumulation in there.
Application: loading of hydrocarbons, toxic and aggressive liquids.
This system includes a long reach loading arm and a vapour return hose.
Loading through the vapour return hose makes the loading procedure more cost-effective as there is neither product emissions and nor personal injury nor pollution of environment.

Application:bottom unloading of chemical and railway tanks
Application: top unloading from railway tanks
By unloading through the nozzles at the end of the drop pipe hot product will be sprayed into the vessel. Thereby the frozen product in the vessel will be warmed up and can be sucked off through the product pipe. The drop pipe is turnable so that the whole railway tank can be reached with hot product.
It is possible to fasten a movable holding bar (or a covering plate) for a level controller. The up and down movement of the A-length is provided by a pneumatic or hydraulic cylinder.
Application: loading/unloading of chemically aggressive products.
