Truck Unload Stations (TUS)

AccesoTruck Unload Stations are used to transfer LPG from supply trucks to the storage tank(s). AES truck unload stations are designed to be anchored in a concrete foundation. They come complete with liquid transfer line and vapor return line. They are equipped with control valves, excess flow valves, vent valves, backcheck valves, and breakaway couplings per NFPA 58. Emergency Shutoff Valves (ESV) with pull cable are standard and pneumatically -operated ESV are available as an option.

Cylinder fill stations, i.e. for filling of forklift cylinders, can be supplied separately, or integrated with the truck unload station.

AES TUSs can also be equipped with Methanol Injection Systems.
