The ICBBI36-UID/S incorporates the unmistakeable design elements that make Sub-Zero a design icon — hand-finished wrapped stainless doors, distinctive louvered grille and sleek hinges. And food stays fresher longer thanks to the most advanced food preservation technology available. The dual refrigeration system, pioneered by Sub-Zero, features two separate cooling systems. Fresh foods thrive in a humid yet chilly climate in the refrigerator, while frozen and convenience foods get the dry, frigid air they need. An air purification system inspired by NASA technology scrubs the air of odour and ethylene gas. Bright LED lighting provides and illuminated interior view, while the discreet interior water dispenser has an advanced filtration system.
