Alfa Laval SB Anti Vacuum House

The Alfa Laval SB Anti Vacuum House is a hygienic safety valve housing designed to prevent tank implosion caused by internal vacuum conditions in closed process systems.

Vacuum conditions commonly occur during tank filling, draining, post CIP cooling, or CO2 cleaning cycles. This anti vacuum solution allows controlled air intake into the tank, protecting equipment and maintaining stable operation.

Designed for integration with SCANDI BREW tank top systems, it is suitable for brewery, food, dairy, and beverage applications.

Features		Benefits
Constructed with high-grade AISI 316L stainless steel, vacuum tail, and EPDM seal Compliant with PED 97/23/EU regulations Designed for integration into SCANDI BREW® tank top systems		Minimizes risk of implosion from vacuum conditions in closed tanks Equipped with a CIP nozzle for thorough Cleaning-in-Place capability Easy to integrate and configure with other tank top valves Low initial cost for a highly effective safety valve solution Enhances long-term system safety and process uptime

How does SB Anti Vacuum House work?

The SB Anti Vacuum House allows controlled air intake when internal tank pressure drops below a safe level.

When used together with safety or regulating valves, it helps balance pressure inside the tank by:

allowing air in during vacuum conditions
releasing pressure when it exceeds the preset limit

This ensures consistent protection and stable tank operation throughout production and cleaning cycles.

FAQ

How can I prevent tank implosion?
