Choosing the Right Tank: FDO vs. Conical Tanks

In the world of industrial storage solutions, not all tanks are created equal. Different applications require different designs, and two popular options often considered are Full Drain Outlet (FDO) tanks and Conical tanks.

Understanding FDO and Conical Tanks

Full Drain Outlet (FDO) Tanks: FDO tanks are engineered with a unique design feature – a full drain outlet at the base of the tank. This design allows for the complete drainage of the tank’s contents, leaving no residue behind. It’s a cylindrical tank with a flat bottom and a specially designed outlet to ensure efficient emptying.

Conical Tanks: Conical tanks are characterized by their conical or sloped bottom design. They come in various sizes and are often equipped with a separate outlet at the apex of the cone. This design promotes the natural flow of liquids towards the outlet, facilitating easy drainage.

Benefits and Ideal Applications

Full Drain Outlet (FDO) Tanks:

  • Complete Drainage: FDO tanks are perfect for applications where you need to ensure that every drop of the stored liquid is used, without any residue left behind. This is crucial in industries where product quality and consistency are paramount.
  • Easy Cleaning: Thanks to their full drainage feature, FDO tanks are relatively easy to clean, minimizing the risk of contamination. This makes them suitable for industries where hygiene is a concern.
  • Batch Processing: FDO tanks are often used in batch processing applications, where it’s essential to completely empty the tank between batches.

Conical Tanks:

  • Gravity Flow: The conical design promotes natural gravity flow towards the outlet, which can be advantageous for applications that require constant, slow draining. It’s ideal for situations where maintaining a consistent liquid level is crucial.
  • Settling Solids: Conical tanks are well-suited for processes involving settling solids. The conical shape allows solids to settle at the bottom while facilitating liquid removal from the top.
  • Waste Collection: They are often used as waste collection tanks due to their efficient drainage and ease of handling waste liquids.

Choosing the Right Tank for Your Needs

To determine whether an FDO tank or a Conical tank is the right choice for your business, consider various factors:

  • Cost: FDO tanks tend to be more cost-effective for their specific applications, while conical tanks may be the better choice if you need their unique benefits.
  • Maintenance: FDO tanks are easier to clean, which reduces maintenance efforts. Conical tanks, while efficient, may require additional maintenance for thorough cleaning.
  • Longevity: Both tank types are durable, but your choice should align with your intended use. Consider whether complete drainage or settling solids are more important for your application’s longevity.

Understanding the distinctions between FDO and Conical tanks is crucial for making informed decisions about your storage needs. Whether you prioritize complete drainage, gravity flow, or other specific features, both tank types have their unique advantages. Assmann’s experts can assist in choosing which tanks will work to optimize your industrial processes.
