HIGH CHEMICAL RESISTANCE
INDUSTRIAL STRENGTH
INDUSTRY LEADER
When it comes to complete liquid drainage and easy maintenance, RotoTank™ Decant Tanks set the standard. Unlike traditional water tanks that retain a small amount of liquid at the base, our decant range is specially designed to empty fully — saving time, reducing waste, and improving hygiene across a wide range of applications.
RotoTank™ Decant Tanks are engineered with a built-in pallet base that sits at a precise angle, allowing the contents to flow naturally toward the outlet point. This clever design ensures that 100% of the liquid drains out, without needing to tilt or manually flush the tank.
This feature makes them the preferred choice in industries where cleanliness, product purity, and efficiency are critical — including chemical handling, food and beverage processing, agriculture, and water management.
Where to Use RotoTank™ Decant Tanks
✅ 100% Drainable Design – No leftover residue or standing liquid. Perfect for applications where product integrity matters.
✅ Easy to Clean & Maintain – The sloped base allows for effortless rinsing and sanitation.
✅ Durable Construction – Manufactured using high-quality, UV-resistant polyethylene designed to withstand South African conditions.
✅ Chemical-Resistant Options – Available in materials suitable for storing fertilizers, chemicals, and other non-potable liquids.
✅ Versatile Use – Ideal for industrial processes, farms, workshops, or any setup where full drainage is required.
✅ Available in Vertical and Horizontal Designs – Choose the configuration that best fits your installation or transport needs.
With decades of local expertise, RotoTank™ manufactures tanks that meet the highest quality and safety standards. Each Decant Tank is rotationally moulded in one piece, ensuring seamless strength and long-term reliability.
We back our products with expert support, free delivery across South Africa, and a reputation built on trust, innovation, and performance.
