DEAERATOR
A Deaerator is a vital component in boiler feedwater systems, designed to remove dissolved gases—primarily oxygen (O₂) and carbon dioxide (CO₂)—from feedwater before it enters the boiler. These gases, if not removed, can cause severe corrosion to boiler tubes, feed lines, and economizers. PP Boilers offers high-performance tray-type and spray-type deaerators engineered to improve feedwater quality, reduce maintenance costs, and extend boiler life.

Key Points
- Oxygen & CO₂ Removal: Strips out corrosive gases to prevent pitting and scaling inside the boiler
- Thermal Conditioning: Heats feedwater upto 150°C, improving boiler efficiency
