Benefits of OPW Top Loading Arms

A good loading system will invariably require the ability to load and unload products without having to move a service vehicle. You’ll need two things to make this happen.

1)Your loading system has to have enough horizontal range to reach the farthest compartment from a single point.

2)Your system will also need enough vertical movement and drop-pipe lengths, so they can reach the service vehicles of varying heights.

OPW top loading arms fulfill both of these features, making your bulk loading and unloading operations much more efficient.

OPW truck loading arms can do more than simplify the loading process.

It can also increase the amount of product that gets successfully transferred. These loading systems can be fitted with tight fill and vapor recovery applications when they are used with other components such as tapered hatch plugs, Civacon overfill and ground monitoring, vapor plates, and inflatable hatch seals to do this, keeping hazardous materials out of the environment and in your compartments. Special OPW top loading arms can also be supplied with other types of valves, fittings, and instrumentation equipment to make them more efficient and versatile, including safety breakaway connections, steam jacketing, heat trace, and ground monitoring.
