Extrol®
Specialty Models
Fill-Trol®: Boiler System Expansion Tank
Fill-Trol combines a boiler system expansion tank with an automatic fill valve to control system pressure. This eliminates the need for a separate, automatic fill valve.
Radiant Extrol®: Radiant Flooring Expansion Tank
The Radiant Extrol Expansion Tank is specifically designed for low temperature radiant flooring systems. These tanks absorb thermally expanded water to keep the system pressure at safe levels then return that water to the system as the temperature cools.
Solar Extrol®: Solar Heating Expansion Tanks
The Solar Extrol Expansion Tank is specially designed for use in high-efficiency solar systems. These tanks absorb thermally expanded water to keep system pressure at safe levels then return that water to the system as the temperature cools.
