Vacuum Breakers – Essential Protection for Industrial Storage Tanks

Ae Wasser provides reliable vacuum breakers, critical safety devices designed to protect industrial storage tanks from the damaging effects of vacuum conditions. These devices automatically vent ambient air into the tank when negative pressure occurs, preventing structural collapse during emptying operations.

Function & Application

• Preventing Tank Collapse: Vacuum can form during rapid fluid withdrawal (e.g., pump suction during emptying). This negative pressure can exceed the tank’s structural integrity, leading to deformation or collapse.
• Automatic Air Entry: Vacuum breakers are precisely calibrated to open at a minimal negative pressure setpoint. Upon activation, they allow atmospheric air to enter the tank, equalizing the internal pressure and preventing vacuum buildup.
• Broad Applicability: Suitable for a wide range of industrial storage tanks, including those for chemicals, fuels, oils, water, and other process liquids.

Sizing & Standards

• API 2000 Compliance: The sizing and selection of Ae Wasser vacuum breakers are performed in accordance with the API 2000 standard (“Venting Atmospheric and Low-Pressure Storage Tanks”). This ensures that the devices are appropriately sized to handle the maximum emptying rates and prevent over-pressurization or vacuum conditions.
• Customized Solutions: We offer a range of vacuum breaker sizes and types to meet specific tank volumes, emptying rates, and operational requirements.

Key Benefits

• Structural Integrity: Safeguards tank walls and roofs from vacuum-induced damage.
• Operational Reliability: Ensures uninterrupted storage and processing operations by maintaining tank stability.
• Safety: Prevents potential catastrophic failures associated with vacuum conditions.
• Low Maintenance: As devices with no moving parts that are subject to vacuum actuation, they require minimal upkeep.
