Pascal technology is a “breakthrough it is truly revolutionary fridge technology” claimed Vanni Parenti Dow’s PU global appliance technology leader based in Coreggio in Italy.
Parenti was making his pitch for Dow’s development of the patented Pascal approach to win the Innovations Award at the 2011 meeting of the Center for the Polyurethanes Industry held in Nashville Tennessee.
Parenti explained that Pascal raises the energy efficiency of refrigerators and freezers by up to 10 percent and cuts fridge demoulding time by up to 50 percent.
Pascal does this by using fast-reacting PU systems based on polyols specially developed by Dow and by filling the appliance cabinets under vacuum to give rapid efficient flow into every part of complex shapes.
The resulting fine-celled foam gives better insulation with all types of blowing agents.
Dow Polyurethanes in cooperation with Cannon SpA who developed the equipment for Vacuum Assisted Injection (VAI) and a Rotojig for fast demoulding officially launched Pascal 9 Sept at a Shanghai Summit 2011 held immediately after the UTECH Asia/PU China 2011 event.
The technology was also a highlight at the World Appliance Expo in Shanghai in March 2011. At this event Qingdao Haier Co. Ltd showed a household refrigerator using the technology made at its Chongqing plant in western China.
This domestic two-door fridge the first A**** rated device made in China consumes 0.19 kwh/24h (average 0.30 – 0.40 kwh/24h for comparable competitor’s models).
Dow has sold Haier a license for Pascal/VAI technology and the Chinese group has converted one line.
