Hi-Level Alarm- An effective means to prevent overfilling of tank is always suggested. In many cases both a primary (metering, scale/weight) and secondary (Hi-Level Alarm on Loading Arm) may be in place.

• For Clear, Light Non-Viscous Materials Civacon Optic Cane Probe (Model 1300/1400)

• For Dark, Viscous Materials A variety of probe styles, manufacturers can be adapted to fit on your OPW Loading Arm. We have experience with most major overfill brands.

Vapor Recovery- Concern for the environment and your employees is of utmost concern. Several options are available to help retain and recover harmful vapors and avoid excessive splashing, each customized to fit your application. Click here for more information on OPW Vapor Recovery Solutions. Heating – Loading Arms can be fully or partially jacketed for efficient handling of asphalt, molten sulfur, waxes, resins and other products that are highly viscous or tend to solidify at ambient temperatures. Click here for more information on OPW Heated Loading Solutions. Loading Arm Insulation – OPW can provide a Custom Insulation Package designed specifically for your loading arm. Unlike field-applied insulation, these packages are completely removable and reusable, making them the ideal solution for loading arm use.

Grounding/Bonding – Suggested for many top/splash loading applications. Available as an option on all Loading Arm designs. 

Electronic Ground Verification

The Civacon model 8030 Ground Verification Monitor is compatible with today’s transport ground systems. The monitor is equipped to provide a permissive signal to allow load rack operation and, if ground is lost, to indicate a non-permissive signal and shut down the loading operation.   Safety Breakaway Coupling Protects your equipment, piping and personnel in the event of an unintended pull-away. A consideration whenever you are making a tight connection to a truck or railcar.   Quick & Dry Disconnect Couplings – With OPW, you have many options at your disposal for your loading arm termination connections. From the original quick-disconnect Kamlok® coupling to our Epsilon™ dry disconnect coupling, we have a coupling to meet your needs.  Vacuum Breaker – OPW Engineered Systems Vacuum Breakers permit quick, positive evacuation of the arm after the loading operation is complete. Suggested for any top load/submerged fill application.  Lockdown- available to help insure that your loading arm stays securely in vehicle during loading operation. Several options available depending on your application.  Deflectors – Loading arm drop tube can be provided with deflector to help minimize the risk of static build-up and/or product foaming. Can also be used to redirect the upward pressure in order to keep the arm from attempting to rise out of tank during loading.
