Polyurethane has unmatched efficiency for cold food chain and it’s more than ever used in refrigeration systems throughout the world. Mastering innovation, Ekosystem designs and manufactures specially-made foaming machines and plants.

The transformative impact of polyurethane foam for refrigeration

As demands for energy efficient transportation and preservation of food continue to rise in cooling industry, rigid polyurethane foam for refrigeration emerges as ideal solution. Its excellent properties as thermal insulating material play a fundamental role allowing for heat retention and preservation of low temperature. This contributes to energy saving and sustainability, that is reduced operational costs and environmental footprint. This is not all: its lightweight and low volume enables the creation of compact and space-saving solutions by using smaller thickness while achieving the same insulation efficiency as with other materials. Nonetheless, its innate structural strength and self-adhesive capability to a variety of substrate ensures a prolonged service life for refrigeration systems.

Polyurethane foam can be adapted to different shapes, sizes and refrigeration requirements making it a suitable choice for both households and industrial cool chain. No matter its end use, Ekosystem designs and manufactures different PU foaming machines and plants for any refrigeration system.

From field to table: PU foam for commercial and domestic refrigerators

Application of rigid polyurethane foam for refrigeration passes through the entire cold food chain as quality must be maintained from production to consumption. First of all, it’s found in refrigeration systems in food processing and storage facilities. Then, when it comes to distribution, containers and truck bodies can be built from polyurethane foam cored panels to ensure food preservation even over long distances. At this point, storage continues in shops and supermarkets before coming at the last chain loop that is consumers’ houses where the most house appliances brands promote the use of polyurethane foam for refrigeration.

In short, rigid polyurethane foam can be injected in doors, panels or gaskets of industrial and domestic refrigeration systems like:

  • cold stores and refrigerated warehouses
  • walk-in coolers
  • blast chillers
  • refrigerated containers
  • refrigerated transport vehicles
  • vertical or horizontal display refrigerated cabinets
  • refrigerated counters
  • vending machines
  • home refrigerators and freezers
  • picnic boxes and coolers

Insulation corner panels

Industrial and domestic refrigeration systems can be manufactured by either an injection method or constructed using panels similar to those used for cold rooms. In particular, corner panels are an essential application of polyurethane foam for refrigeration. When we think about sandwich panels, our mind usually thinks of their best-known version, that is a construction material made of two layers, a PU core and equipped with joints and fasteners making it a simple and construction-friendly solution. In cold rooms and refrigerated storages, thermal dispersion is a critical point: especially on corners, the use of joints to connect panels creates thermal bridges affecting insulation properties. In fact, if junctions are not excellent and the panels not perfectly aligned, the outside temperature will affect the inside one with significant consequences on the cold room purpose and use and causing waste of energy. Corner panels are the perfect solutions to avoid this problem: the lack of fastening and joints eliminates any risk of thermal dispersion.
