Alfa Laval SB Anti Vacuum House

The SB Anti Vacuum House is a robust and hygienic safety valve housing designed to prevent tank implosion caused by internal vacuum conditions in closed process systems. These vacuum events typically occur during dynamic production phases such as tank filling, draining, post-CIP cooling or CO₂-based cleaning cycles. In such scenarios, a reliable vacuum protection valve is essential to safeguard both product integrity and equipment longevity.

Built for integration into SCANDI BREW® tank top systems, the anti vacuum house is ideal for hygienic operations in the brewery, food, dairy and beverage industries. It serves as a critical component of your tank safety valve setup, ensuring long-term reliability, process safety and compliance.

How does SB Anti Vacuum House work?

The SB Anti Vacuum House protects against tank collapse by enabling controlled air intake when internal pressure drops dangerously low. In combination with safety valves, it allows pressure discharge once it exceeds the preset value. When paired with regulating valves, this vacuum protection valve ensures balanced pressure relief and maintains optimal tank safety under vacuum conditions.

FAQ

How can I prevent tank implosion in the beverage industry?
Using a reliable anti-vacuum device like the SB Anti Vacuum House helps prevent implosions by functioning as a vacuum protection valve. It allows controlled air intake into the tank as part of a vacuum relief system, maintaining structural integrity and operational safety in hygienic beverage production tanks.

What is the best vacuum protection valve for food processing tanks?
The Alfa Laval SB Anti Vacuum House is widely recognized as a trusted tank safety valve and hygienic tank vacuum valve for food, beverage, dairy, and brewery applications. It ensures vacuum protection by maintaining consistent internal pressure during processes like cool rinsing and tank emptying, which can cause internal vacuum conditions.

What are the symptoms of a bad vacuum control valve?
Symptoms of a failing vacuum control valve include unexpected pressure build-up, delayed air intake during tank emptying and abnormal vacuum-related stress on the tank structure. Using a reliable solution like the SB Anti Vacuum House ensures consistent performance and long-term tank protection.
