Insulation is best
The results showed that the 70-L PUR container with lid performed by far the best
Dr Björn Margeirsson, Research Manager at RPC Sæplast and Assistant Professor at the University of Iceland together with three of his students performed an ice melt study, comparing the Sæplast 70-L PUR container, with and without a lid, with 70-L single walled PE boxes. They monitored the ambient temperatures and the melting of the ice and calculated the insulation values for the three different formats.
The results showed that the 70-L PUR container with lid performed by far the best, the insulation value being notably higher than even the double-walled version without a lid. By far the lowest insulation value came from the single walled PE container, with the 70-L PUR container with lid providing five times better insulation.
“The huge difference in insulation capabilities was one of the reasons for the quick transition from single walled boxes to these insulated containers in Icelandic fishing fleets in the 80s,” explains Dr Margeirsson. “The other main reasons were easier, faster and better handling onboard and ashore, and these benefits remain critical to the continued success of our ranges today.”
The Sæplast 70-L PUR container features a seamless roto moulded construction that ensures a robust and reliable long-term performance. PUR refers to the polyurethane insulation injected into the walls of the tub that delivers a very high insulation factor for effective temperature retention and control.
