Secondary containment system for DEF storage container

Abstract

A secondary containment system used to transport and store a tank containing diesel exhaust fluid. The secondary containment system having a containment body comprising an end wall, a back wall, two side walls, a bottom, and a top, wherein the walls are integral to the bottom, and wherein the top can be displaced from the containment body. The containment body is constructed of a three-layer configuration comprising an inner layer, an outer layer, and a central layer sandwiched therebetween. The inner layer defines a chamber in which the tank containing diesel exhaust fluid is stored. The chamber is sized and shaped so that the tank is positioned in the chamber and defines a void between walls of the inner layer and the tank containing diesel exhaust fluid. The inner layer and outer layer are preferably constructed of a UV protected polyethylene, and the central layer is constructed of a 2″-2 lb. density polyurethane insulation material having an R17 value.

AI Technical Summary

Benefits of technology

[0015]The inner, outer and central layers that define the secondary containment system have the primary task of maintaining the temperature of the DEF storage tank during transport and storage. The secondary containment system including the central layer assists in insulating all sides of the DEF tank from varying temperature conditions. In addition, the three-layer containment system protects the DEF storage tank during transport and storage.

Problems solved by technology

PM has been linked to higher incidences of childhood asthma, among other health hazards.
