Vacuum rated tanks for industrial processes
Vacuum rated tanks are designed to withstand negative pressure without deforming. Unlike standard tanks, these tanks are sized for vacuum conditions that may occur during emptying, cooling or internal process reactions. Processöverskott offers vacuum-rated tanks in stainless steel 304 and acid-resistant 316 in various designs for industrial processes in areas such as food, chemicals, pharmaceuticals and water treatment.
Function and structure
Vacuum rated tanks are reinforced to withstand negative pressure and reduce the risk of deformation.
Common construction details:
– Reinforced tank walls and bottoms
– Stabilizing rings and ribs
– Customized plate thickness depending on vacuum level
– Reinforced welds and connections
– Vacuum valves and pressure relief valves
– Possibility of agitators and internal process equipment
Materials and construction
Vacuum tanks are usually manufactured in:
– 304 stainless steel for standard applications
– 316 or 316L acid-proof for more corrosive environments
The choice of materials has an impact:
– Corrosion resistance
– Resistance to vacuum and pressure variations
– Hygiene and cleanability
– Lifetime and maintenance needs
Documentation linked to, for example, CE and PED may occur depending on the design and specification of the tank.
Pressurized and atmospheric solutions
Vacuum rated tanks are designed for negative pressure and are different from standard atmospheric storage tanks.
In vacuum operation, tanks can be equipped with:
– Vacuum valves
– Pressure relief valves
– Pressure monitoring
– Reinforced structures and fastenings
The choice of tank type is based on process requirements, operating conditions and safety needs.
Applications in industry
– Food industry – vacuum processes and distillation
– Chemical industry – reactors and gas-emitting processes
– Pharmaceutical production – vacuum drying and filtration
– Water treatment – vacuum filtration and degassing
Technical options and equipment
– Vacuum gauges and pressure sensors
– Safety valves for overpressure and underpressure
– Inspection hatches and sample points
– Internal agitators and CIP systems
– Temperature jacketing and insulation
– PLC and SCADA integration
Volumes and capacity
Vacuum rated tanks come in many different sizes depending on the process and application.
Sizing is influenced by, among other things:
– Tank diameter and height
– Vacuum level and operating conditions
– Liquid properties
– Temperature and process requirements
– Possible internal components
Advantages of vacuum rated tanks
– Withstands negative pressure without deformation
– Adapted for industrial vacuum processes
– Hygienic solutions for sensitive processes
– High corrosion resistance and long service life
– Available as both new and used solutions

Availability and documentation vary depending on the site and previous use.
Choosing the right vacuum tank
Vacuum tank selection is usually based on:
– Vacuum level of the process
– Chemical properties of the liquid
– Temperature and hygiene requirements
– Volume and installation environment
– Documentation and certification requirements
Correct sizing is important for safe operation and long service life.
Executive summary
Vacuum-rated tanks are used in industrial processes where negative pressure exists and where standard tanks are not sufficient. With the right design, choice of materials and construction, the tanks can be used in the food, chemical, pharmaceutical and water treatment industries. Processöverskott offers vacuum-rated tanks in stainless steel 304 and acid-proof 316 in several different designs depending on the process and application.
