A stratification tank, also known as a heat recovery tank, is a specially designed stainless steel tank that stores liquids at different temperatures by creating distinct thermal layers. This stratification improves energy efficiency by minimizing the need for additional heating or cooling, making these tanks ideal for heat recovery applications across various industries.
Gpi designs and manufactures custom stratification tanks, fully tailored to your process requirements. Our tanks maximise energy recovery and contribute to your sustainability goals.

FAQ
What is a stratification tank?
A stratification tank, also called a heat recovery tank, is a stainless steel tank that stores liquids at different temperatures in distinct thermal layers. This makes it possible to store and recover heat with minimal additional heating or cooling.
How is a thermal storage tank sized?
The volume depends on the amount of energy to be stored, the temperature difference between the hot and cold layers, the charge and discharge flows and the available space. Gpi Tanks XL calculates the optimal volume and connections for your process.
Can a stratification tank store both hot and chilled water?
Yes. Gpi Tanks XL designs stratification tanks for storing hot and cold liquids and for managing thermal buffers within an installation
