TECHNOLOGY AND FUNCTIONALITY


In the beginning the thermal insulation between refrigerator door and cabinet was ensured by means of tube-shaped extruded profiles made of vulcanized rubber and welded together by using filling materials, which are squeezed in between the closing frames by a ratchet closure mechanism.
ILPEA designed and manufactured a sealing system that used a PVC compound gasket profile with no plasticizer migration, which, thanks to the insertion of a flexible magnetic strip inside the gasket, allowed the perfect closing of the door, thereby overcoming the need of a ratchet closure. This solution has dramatically changed the concept of thermal insulation in the refrigerator and freezer sector and has allowed ILPEA to reach a position as worldwide market leader . The company is constantly researching new and groundebraking solutions and has developed four main product lines.

Magnetic and non-magnetic soft PVC or TPE (PVC-free) gaskets. This is the first product line developed by company’s plastics division. The gasket profile design is constantly being updated and improved so that we can always offer to our customers innovative products, both in terms of performances and materials, which possess the highest sealing, springback and rolling effect properties.
"Push-in" type, tri-extruded magnetized TRIO gasket. This gasket profile is made from coextruded rigid and soft PVC and PU compounds, which besides providing excellent sealing properties also enhance energy-saving characteristics on refrigerator and freezer doors. Solutions for the automatic assembly of refrigerator and freezer doors. The Trio profile is protected by an international patent. For use on refrigerator doors, upright and combined freezers.

PVC or TPE (PVC-free) Twin gaskets (Ilpea’s patent) The Twin gasket line is the most innovative range of products in the industry. The gaskets consist of coextruded profiles which are made by combining soft and rigid material in one single piece. The rigid part of the profile is the mounting piece and is fitted with a flexible clip for snap fastening of the gasket to the door liner. The soft part has a flexible balloon shaped design and is the sealing bellow the door shuts onto. These gaskets allow the automatic assembly onto the door liner, as well as making spares parts replacement extremely easy. In addition, they have improved aesthetics and performances compared to ordinary gaskets, and have an increased life expectancy.

PVC or TPE (PVC-free) Trio gasket. Ilpea’s patent. This state-of-the-art gasket has been designed and patented by Ilpea to meet the need of enhanced  sealing capabilities and energy consumption reduction of refrigerators. The gasket is made by coextruding three different materials, a rigid one, a soft one and one that remains flexible also at very low temperatures. The rigid profile section consitutes the mounting piece and may have any shape, ranging from a Twin gasket to a Push-in gasket to an ordinary foamed gasket. The flexible bellow is made by using a soft material, just like an ordinary gasket. The material , withstanding very low temperatures, is used to provide a further bellow that closes the gap between door liner and case liner in a more deep-seated area compared to the first gasket, thereby reducing to a minimum the exchange of heat with the environment and compensating for any misalignments between the door and fridge case surfaces. The energy consumption of the refrigerators on which the Trio gaskets have been tested has been cut down by 1 to 7%.

Rigid frames for chest freezers and refrigerated display cabinets. ILPEA offers a wide range of hard, shockproof PVC gasket frames. Thanks to a special process developed by our company, it is now possible to round off the 90° corners of the frames, with internal and external radiuses of up to 30 mm, on three dimensions.
