Can stainless steel tanks be left outside during winter?
Stainless steel tanks can in many cases be placed outdoors even in winter conditions, depending on their insulation, construction and use in the process industry.
Tanks can be equipped with, for example, insulation such as PU or other solutions, together with tight lid construction and in some cases heating cables. These measures can help to reduce the impact of low temperatures and manage freezing risk in different applications.
Processöverskott offers stainless steel tanks in stainless steel 304 and acid-proof 316/316L in various sizes and designs. Tanks with insulation are available in the range, where the design and specifications vary depending on the model and previous use. Documentation linked to PED and CE, for example, may be available where indicated.
Function and structure
Outdoor tanks can be designed to cope with the impact of low temperatures and weather conditions, depending on their design and use in the process industry.
The construction may consist of several parts:
- Inner tank in stainless steel 304 or acid-proof 316/316L
- Insulation layer, for example PU or mineral wool
- Outer sheet, often stainless steel, to protect against the weather
- Seals and covers that can help reduce the impact of cold and moisture
The design and choice of materials will vary depending on the tank design, model and previous use.
Materials and construction
Acid resistant 316/316L is often used in applications where chemical stress or corrosive environments occur in the process industry.
Insulation in the form of PU or mineral wool can be used depending on the needs and design. PU is used in solutions where low weight and thermal insulation are relevant, while mineral wool is used in applications where, for example, temperature resistance, moisture or fire protection may be factors to consider.
Material selection and design can affect durability, cleanability and performance of the tank over time, depending on the application and operating conditions.
Pressurized and atmospheric solutions
Outdoor tanks can be pressurized or atmospheric. Pressurized tanks must be sized for design pressure and temperature variations. The insulation should protect against both heat loss and the risk of condensation and frost.
Applications in industry
- Food industry – storage of liquids such as milk, syrups and oils
- Chemical industry – temperature sensitive chemicals
- Pharmaceutical production – liquids requiring constant temperature
- Water treatment – hot water and chemicals during cold periods
Technical options and equipment
- Insulated caps and pipe connections
- Heating cables for frost protection
- Temperature and level sensors
- Moisture and condensation protection
- PLC or SCADA integration
Volumes and capacity
Insulation and protection in tanks is usually customized based on factors such as tank volume, fluid properties and operating environment in the process industry.
Processöverskott offers tanks in different sizes and designs. Tanks with insulation are included in the range, where the design and solutions vary depending on the construction, application and previous use.

Which material is best for outdoor tanks?
Acid resistant 316/316L is often used in applications where the environment can be more corrosive or where tanks are exposed to varying operating conditions, for example in the process industry.
Insulation in the form of PU or mineral wool can be used depending on the design and needs. These solutions can help limit heat loss and manage temperature impacts, including cold in certain environments.
Stainless steel outer shells are used in many structures and can be important for protection against external influences and maintenance, depending on the application.
Can pressurized tanks be left outdoors?
Yes, pressurized tanks can be left outdoors if the design pressure, seals and insulation are dimensioned for temperature variations. The insulation should protect against both heat loss and condensation.
Do outdoor tanks need extra protection in winter?
Yes, insulated lids, heating cables and proper insulation are important to prevent freeze damage. The location of the tank should also be protected from direct wind and precipitation.
Can used tanks be used outdoors?
Used stainless steel tanks can in some cases be supplemented with insulation, such as PU or mineral wool, and in some cases be equipped with heating cables depending on the design and application.
Process surplus offers tanks where different solutions for temperature management can be present or adapted as needed. Possibilities for execution, completion and documentation vary depending on the condition of the tank, previous use and technical conditions.
