Poly and PCO tanks are used for a wide variety of applications, from spraying to long-term storage. If you’ve ever wanted to know more about them, though, you’re not the only one. Here are a few of the most commonly asked questions about poly tanks.

What Is a Poly Tank?

“Poly” is short for polyethylene, a type of durable, nonreactive plastic used to make liquid storage tanks. Poly tanks come in all shapes and sizes.

What Is a PCO Tank?

PCO stands for “pest control operator”. PCO tanks are simply poly tanks that are specially designed for pesticide dispersal.

What Kinds of Liquids Can Be Stored?

Because poly tanks are so strong and resistant to chemical reactions, a variety of different chemicals can be stored within them. Unlike some metal tanks, they won’t corrode or react with the contents. It is important to remember, however, that tanks have a limit when it comes to the weight of the liquid they can carry. It’s generally recommended that liquids with a specific gravity of over 1.7 should not be stored in a poly tank.

A few liquids that can be kept in poly tanks include:

• Water
• Herbicides
• Insecticides
• Cleaning solutions

What Are Some Potential Applications?

Poly tanks can be used for many different purposes; a common one is storage of industrial chemicals. They can also be used as sprayer tanks, working as part of an spray rig designed to disperse pesticides or other liquids.
