Polar King Past Project: Automotive Chemical Storage. Polar King built this customized 6’x12’ explosion proof trailer for an automotive company in Arizona. They required a mobile trailer unit that could provide safe and effective chemical storage. The called for several additional safety features as well as a unit that complied with chapter 5 of the National Electric Code. 

Polar King Past Project: Automotive Chemical Storage

Class 1, Division 2 Explosion Proof Unit

This refrigerated trailer unit was required to store temperature sensitive chemicals for the automotive industry. In order to safely store these chemicals, our client required a class 1, division 2, explosion proof refrigerated trailer.

Class 1: Flammable gases or vapors are present in the air in quantities sufficient to produce explosive or ignitable mixtures.

Division 2: The substance referred to by class is present only in abnormal conditions, such as a container failure or system breakdown.

Lift Gate and Stabilizer Jacks

Due to an employee safety program, our client elected to include a rear lift gate with stabilizer jacks. The lift gate allows users to easily move heavy or large barrels of chemicals in and out of the unit. They can also raise or lower the barrels, rather than haul them up a ramp.

For stability purposes, there are two stabilizer jacks. These ensure the unit will not tip backwards while loading and unloading.
