AUTOMATIC AIR-VENT VALVE ECO 1/2''
Automatic Air‑Vent Valve ECO
Float‑operated automatic deaerator valve for solar thermal circuits
The Automatic Air‑Vent Valve ECO is engineered to continuously and autonomously purge air from solar thermal systems—especially glycol loops—preserving efficiency and preventing common issues like corrosion, noise, overheating, and pump cavitation. Designed for high-temperature applications (up to 180 °C) and reliable operation under up to 10 bar pressure, it’s a maintenance-minimal solution for installations at high points such as panel headers or buffer tank tops.
