PU insulation for industrial containers and process solutions
PU insulation, or polyurethane insulation, is used in industrial containers to maintain temperature and improve energy efficiency in industrial processes. The insulation protects the contents from heat loss, freeze damage and condensation while contributing to stable operation and reduced energy consumption.
Process Surplus offers stainless steel tanks in AISI 304 and 316 with PU insulation in volumes from 100-250,000 liters for the food industry, chemical industry, pharmaceutical production and water treatment.
Function and structure
PU insulation acts as a thermal shield between the tank contents and the surrounding environment.
The construction usually consists of:
Stainless steel inner tank
Polyurethane foam with low thermal conductivity
Stainless steel outer casing or cladding
Seals and connections adapted for hygiene and temperature control
The insulation is placed between the inner and outer jacket of the tank to reduce heat transfer and stabilize the process temperature.
Materials and construction
PU insulated tanks are usually made of stainless steel AISI 304 or AISI 316 depending on the chemical properties and hygiene requirements of the liquid.
AISI 304 is often used in food production and water treatment, while AISI 316 or 316L is used for corrosive liquids and chemical processes.
Polyurethane insulation is lightweight and has good insulating properties while contributing to energy-efficient operation.
Pressurized and atmospheric solutions
PU insulation can be used on both atmospheric and pressurized tanks.
Pressurized tanks require construction and seals that can withstand design pressures, working pressures and temperature variations according to applicable requirements and documentation.
Atmospheric tanks often use insulation to reduce energy losses and protect the contents from external temperature influences.
Applications in industry
PU insulated tanks are used in several industrial areas where temperature control is important.
Common uses are:
Food production for dairy products, oils and syrups
Chemical industry for temperature sensitive liquids
Pharmaceutical production with stable storage temperature requirements
Water treatment where freeze protection and energy efficiency are important
Process industry where temperature stability affects product quality and operation
Technical options and equipment
PU insulated tanks can be equipped with:
Temperature monitoring and level measurement
Agitators and mixing equipment
Insulated caps and pipe connections
Cooling or heating jacket
CIP system for hygienic cleaning
PLC and SCADA integration for monitoring and control
Volumes and capacity
Process Surplus offers PU insulated tanks in volumes from 100-250,000 liters.
Smaller tanks are often used in laboratories and pilot plants, while larger tanks are used in full-scale production and storage.
The thickness and design of the insulation is adapted to the tank size, temperature requirements and operating environment.
The benefits of PU insulation
PU insulation offers several technical and operational advantages:
Reduces heat loss and energy consumption
Protects against frostbite and temperature fluctuations
Reduces condensation
Provides more stable process temperature
Low weight in relation to insulation capacity
Can be used on both pressurized and atmospheric tanks

Choosing the right PU insulation
The choice of insulation is based on several factors such as:
Tank volume
Temperature requirements
Properties of the liquid
Pressure conditions
Operating environment and climate
Hygiene requirements and cleaning needs
Processöverskott offers advice on the choice of tank, insulation and technical options depending on the application and process requirements.
Executive summary
PU insulation is used in industrial containers to maintain temperature, reduce energy losses and protect contents from freeze damage and condensation.
AISI 304 and 316 stainless steel tanks with PU insulation are used in the food, chemical, pharmaceutical and water treatment industries where temperature control and energy efficiency are important parts of the process.
