Midland, Michigan -- Dow Polyurethanes, in cooperation with Cannon SpA, says the Pascal polyurethane insulation technology, pioneered last year for household refrigerators and freezers, is now available to retrofit to existing production lines.
"We've listened to our customers and created a solution so they can use Pascal technology by upgrading their production lines, but not having to build a brand new line, to meet consumer demand for energy efficient refrigerators," said Mark Bassett, global vice president for Dow Polyurethanes, in a Dow statement.
"With the ability to retrofit Pascal to existing production systems, manufacturers benefit from increased production efficiency and consumers benefit from refrigerators with higher energy efficiency," Bassett added.
Launched in 2011, Pascal PU foam insulation technology raises energy efficiency in refrigerators and freezers by up to 10 percent, the developers claim. The technology also significantly decreases fridge fill time and enables manufacturers to reach up to 50 percent higher productivity rates, while continuing to provide thermal conductivity and adhesion at typical industry-applied density -- two qualities unique to polyurethane insulation, says Dow.
Pascal Retrofit incorporates vacuum equipment from Cannon SpA during the insulation process to bypass the deficiencies of standard insulation. According to Dow, The vacuum, paired with a hydrocarbon blowing agent, allows Pascal polyurethane foam to flow into small spaces traditional insulation foam might miss, especially in modern designs, and also mould to the contours of the appliance, reducing the amount of energy lost during consumer use.
