RotoTank’s chemical storage tanks are engineered for durability, offering safe and reliable containment for a wide range of chemical substances across domestic, agricultural, industrial, and commercial sectors. Whether you are storing liquid fertilisers, diesel, oil, or high-density chemicals like molasses, RotoTank has a chemical tank solution to match your needs.
Medium-Duty vs Heavy-Duty Chemical Tanks
Our medium-duty chemical tanks are ideal for storing substances with a lower Specific Gravity (SG), such as diesel, oil, and certain liquid fertilisers.
For more corrosive or dense substances, our heavy-duty chemical tanks are designed with extra-thick walls to safely store stronger fertilisers, molasses, and other high-SG chemicals.
What is Specific Gravity (SG) and Why Does It Matter?
Specific Gravity (SG) measures the density of a liquid compared to water. The higher the SG of a chemical, the more pressure it exerts on the tank walls.
At RotoTank, our chemical tanks are SG-rated to match the storage requirements of different chemicals:
Lower SG = Medium-duty tank
Higher SG = Heavy-duty tank with reinforced walls
This ensures structural integrity, chemical resistance, and long-lasting performance under tough conditions.
