Equipped for extreme weather conditions
Insulated tanks Outdoor tanks are often exposed to extreme temperature fluctuations and weather conditions. In Siberia it can get -40° cold and in Congo +40° heat is possible. Insulation is an important part of tank production to ensure that the contents of the tank are not affected.
Thermal insulation
Rock or mineral wool is used for insulation as it is resistant to high temperatures. The insulating materials must be chlorite-free in order not to attack the stainless steel. After installation, the insulation is covered with trapezoidal or smooth sheet metal made of aluminium or stainless steel. However, it can also be welded gas-tight with a stainless steel jacket.
Cold insulation
1. PU foam: A high-quality polyurethane foam is foamed onto the tank. This requires approx. 45 to 50 kg PU foam per cubic metre. Foaming requires a high level of expertise and is only carried out by experienced specialists at GROSS. Otherwise, the insulation material may be distributed irregularly, which at the same time results in irregular insulation. For this reason, the AGI standard stipulates that foaming may only take place at a certain temperature in order to avoid irregularities.
2. Armaflex: These insulation boards made of flexible foam plastic are glued onto the tanks. Then a trapezoidal or smooth sheet metal cladding is mounted over them.
