Aqueous solutions of propylene glycol display excellent antifree2e properties and are therefore valuable as low temperature heat-transfer fluids. For apphcations involving indirect food contact, heat-transfer fluids formulated with the USP grade product are preferred, since there could be inadvertent contact with a food product. These fluids are commonly used in the brewing and dairy industries as well as in refrigerated display cases in retail grocery stores. 

In the next figure (Fig. H-72) basic refrigeration systems are displayed more detailed. More elaborated approach is presented in the text. 

The effects of trends toward lower efficiency and higher energy-consuming features and the countervailing force of policy inteiwentions is illustrated in Figurel, which displays the history of refrigerator energy consumption. 

Radiant heat is not a serious factor in commercial or industrial refrigeration systems, being confined to sunshine through refrigerated display windows (which should have blinds) and radiation into open shop display cabinets from lighting. (See also Chapter 26.)... 

Food could be stored in refrigerators or freezers, which can recognize the type and date of the goods stored. If some goods reach their use-by date, it is brought to the attention of the user. When food is taken out of the freezer, a reminder will be displayed to buy more, or, if the user has subscribed to a re-stocking service, it may even automatically order from the supplier.

Figure 3.9. Generalized overview of the industrial-scale manufacture of recombinant E2 classical swine fever-based vaccine, using insect cell culture production systems. Clean (uninfected) cells are initially cultured in 500-1000 litre bioreactors for several days, followed by viral addition. Upon product recovery, viral inactivating agents such as /i-propiolactone or 2-bromoethyl-iminebromide are added in order to destroy any free viral particles in the product stream. No chromatographic purification is generally undertaken as the product is substantially pure the cell culture media is protein-free and the recombinant product is the only protein exported in any quantity by the producer cells. Excipients added can include liquid paraffin and polysorbate 80 (required to generate an emulsion). Thiomersal may also be added as a preservative. The final product generally displays a shelf-life of 18 months when stored refrigerated...

Purification entails use of an immunoaffinity column containing immobilized murine antifactor VII antibody. It is initially produced as an unactivated, single chain 406 amino acid polypeptide, which is subsequently proteolytically converted into the two-chain active factor Vila complex. After sterilization by filtration, the final product is aseptically filled into its final product containers and freeze-dried. The excipients present in the product include sodium chloride, calcium chloride, polysorbate 80, mannitol and glycylglycine. When freeze-dried in the presence of these stabilizing substances and stored under refrigerated conditions, the product displays a shelf-life of at least 2 years. It has proved effective in the treatment of serious bleeding events in patients displaying anti-factor VIII or IX antibodies. 

Small pieces find many diverse applications, for example in toys, door latches, display boards, TV tube correction magnets, etc., and the plastic composite variety is best known as a refrigerator door seal (Fig. 9.59(c)).
