### Dual Refrigeration The PRO 48 continues the Sub-Zero tradition of superior quality and reliability. Sub-Zero pioneered the development of ourdual refrigeration system, giving you optimum fresh and freezerfood storage in ideal self-contained sections. Both refrigerator and freezer maintain accurate, consistent temperatures. Dual refrigeration keeps your food fresh longerthan any othersystem available. With dual refrigeration, thefreezer maintains a constant temperature within one degree ofthetemperature you set within our range of -soF (-21'C) to +soF (-15'C), without unwanted moisture and odorfrom the refrigerator. Similarly, you can adjustthe refrigerator temperature within a range of 34°F WC) to 4soF (7'C), for proper humidity levels tailored for longerfood life expectancy. The dual refrigeration system also means there is no transfer offresh food odorsto frozen food or ice. The Sub-Zero system does not freeze the moisture out ofthe air in the fresh food section. Sub-Zero dual refrigeration is also more energy efficient than old-fashioned single refrigeration systems. When the refrigerator is used frequently during the day it does not require the freezer to circulate its very cold, dry airto the refrigerator. Instead, the refrigerator uses moist airto keep fresh foodsfresh and energy use minimal.
