A loading system should have sufficient horizontal range to reach the farthest compartment without re-spotting the vehicle. Sufficient vertical movement and drop-pipe lengths for servicing vehicles of varying heights are also necessary. A properly designed top-loading system can achieve this requirement. Top-loading can also be used for tight-fill and vapor-recovery applications when used with specially designed and engineered components, such as vapor plates, tapered hatch plugs, and inflatable hatch seals. The 7300 IHS Inflatable Hatch Seal is a device for sealing different hatch openings on tank trucks and railcars to prevent the release of vapors into the atmosphere. Special top loading designs also can be supplied with a wide range of valves, fittings, and instrumentation equipment. OPW Engineered Systems has a long, established reputation in the petroleum, chemical and food industries for providing effective loading and unloading systems to handle liquids safely and efficiently. We work closely with you to design the best system for your application. T O P L O A D I N G O V E R V I E W
