Planning Your Horizontal Tank Purchase

Purchasing a liquid storage tank for your rural home, farm, or business is unlikely to be a frequent purchase. That’s why we want to make sure you have all of the resources needed to make a confident and educated purchase decision. 

Below you’ll find some of the most commonly asked questions we get from our customers regarding Horizontal Tanks.

Why choose a Horizontal Tank?

Horizontal Tanks are available in multiple shapes, including free-standing with moulded in legs, round – requiring a metal stand, and lower profile elliptical with moulded in legs. Horizontal tanks are designed with thicker walls and a lower center of gravity that make it the tank of choice for mobile applications. Most commonly, they’re used in the back of a truck, on a flatbed trailer for towing on a farm, or for water delivery vehicles. If you’re looking for a stationary tank, Vertical Liquid Storage Tanks may be the better option for you.

Which tank is (likely) best for your needs?

Depending on the purpose of your tank, you may have different considerations. The obvious being size, where pickup trucks will tend to have smaller tanks, farmers and water delivery trucks will likely end up with tanks in the 2000 USG to 4000 USG range. 

Towing capacity is a major consideration. You want to ensure the vehicle is capable of consistently hauling your tank once it is full.

As a basic example, water weighs 8.34lbs or 3.785 kgs per US Gallon, and an average pickup truck bed is 72” x 60”. This means the FS0335-44, a 335 US Gallon Free Standing Horizontal Tank measuring 44″ x 44″ x 56”, with a weight of 118 lbs would easily fit in the back of most trucks. However, once that tank is full it will hold 2793.9 lbs or 1267.98 kgs or water, making the total weight 2911.9 lbs. As an example, the Ford F150 regular bed truck is rated for 2900 lbs. That means that this water tank alone would require this truck bed to be at capacity every time it’s being used.

The bottom line with weight is to understand your vehicle, trailer, or flatbed capacity and take it into consideration when choosing your tank.

What chemicals can I store in Ace Roto-Mold liquid storage tanks?

The most accurate resource for this is the Chemical Resistance Data Chart on pages 21-23 of this pdf. This will determine if the chemical to be stored is compatible with polyethylene. If this resistance data does not list the chemical you intend to store in the tank, contact the chemical manufacturer for recommendations regarding storage in polyethylene tanks. The most common uses of these tanks include fertilizer for farms, oils or petroleum, and water.
