HFT Diaphragm Tanks
The Series HFT tank is designed to absorb the force of thermal expansion of heating water and to maintain proper pressurization in a closed hydronic system. The heavy duty butyl diaphragm separates system water from the air in the tank preventing water logging problems.
Features and Benefits- Residential and Light Commercial Applications.
- Helps Prevent Excessive Pressures in Heating Systems.
- Increases System Performance.
- Reduces Oxygen Corrosion.
- In-line and Floor Mount Installation.
