The proof: Case Studies
The estimated investment cost in the comparison with current energy prices takes into account e.g., the increased insulation and cladding material costs and inflation, and therefore an estimated increase has been added to the cost of insulation investment.
# 1. Refinery | Oil storage tank roof
Storage temperature: 60°C / 140°F
The situation: The roof of an aged storage tank containing oil at 60 °C was heavily corroded.
The solution: The roof was replaced with a basic 30 mm insulation solution equivalent to the VDI Energy Class G, applied with a long-lasting and effective corrosion protection system.
