Clearly, it is crucially important for the refrigeration industry to use the most thermally efficient insulation material available, in order to keep the thickness of the insulation to a minimum, and to maximise internal storage space.
IFS have developed a range of refrigeration-grade polyurethane foams which offer outstanding insulation performance with exceptional flowability, allowing the foam to fill complex shapes at relatively low densities. In 1988, we introduced the first commercially available PU foam to use blowing agents with zero ODP (ozone depletion potential), and our Envirofoam Z series of products has become the industry standard for environmentally acceptable polyurethanes.
In addition we are now extending our technical leadership with foams manufactured from rapeseed oil polyols. Conversion of the vegetable oil uses only around 10% of the energy required to convert petroleum-based products, and another huge energy saving is achieved by local sourcing of the raw materials, allowing manufacturers of commercial refrigeration equipment to achieve significant reductions in the size of their carbon footprint. Refrigeration-grade resins are supplied in 200 and 1,000 litre containers, and in 20,000 litre bulk tanks.
