551 Series DISCAL® Deaerator – Remove Air Fast | 3X HVAC Efficiency

Deaerators are used to continuously remove the air contained in the hydraulic circuits of heating and cooling systems.

The air discharge capacity of these devices is very high.

They are capable of automatically removing all the air present in the system down to micro-bubble level.

The circulation of fully de-aerated water enables the systems to operate under optimal conditions, free from any noise, corrosion, localized overheating, or mechanical damage. In the threaded versions it is available for installation on horizontal pipes, and with adjustable T-fitting for installation on horizontal and vertical pipes.

Eliminate Air, Enhance Efficiency: Meet the 551 Series DISCAL® Deaerator

Say goodbye to trapped air and hello to seamless heating system performance. The 551 Series DISCAL® Deaerator is your ultimate solution for automatic air removal in closed-loop heating and cooling systems. Designed for precision and reliability, it continuously eliminates microbubbles and air pockets, protecting your system from corrosion, noise, and inefficiency.

This essential component ensures smooth circulation, reduced energy waste, and an extended lifespan for boilers, radiators, and piping. Whether for residential, commercial, or industrial applications, the DISCAL® stands out as a game-changer in HVAC system maintenance.

Engineered for Performance: Advanced Construction & Easy Installation

Crafted with high-resistance brass and corrosion-proof components, the 551 Series DISCAL® is made for longevity and optimal performance under pressure. Its vertical installation design saves space and simplifies integration into existing systems.

Featuring an automatic venting mechanism, it actively purges air without manual intervention, giving technicians and homeowners peace of mind. This deaerator is pressure-rated, leak-tested, and designed to meet the highest industry standards, making it a smart investment for modern mechanical systems.

Protect Your System, Save Money

Air in your system isn’t just annoying—it’s expensive. From pump cavitation to rust and scale buildup, poor air management leads to reduced heat output and higher maintenance costs. The 551 Series DISCAL® Deaerator prevents these problems by maintaining optimal system pressure and heat transfer, resulting in lower energy bills and fewer service calls.

Improve comfort, reduce wear, and maximize efficiency across all HVAC setups—the DISCAL® does the heavy lifting, so your system doesn’t have to.
