Storing materials in drums and barrels can be problematic for all but the most shelf-stable products. Foods, chemicals, spray foam, epoxies, resins, and other industrial materials often have stringent temperature-range storage requirements. It's important to store these chemicals at optimal temperatures. Effective drum and barrel heaters eliminate waste and lower costs that arise from damaged materials caused by improper storage. If these fragile materials spend time outside of the ideal temperature zone, the longevity can be drastically reduced, which results in and wasted product. This inflates costs and strains budgets.
