The Chef Base series is equipped with innovative features that protect from heat-induced distortion of the work top surface caused by prolonged exposure to mounted cooking equipment. Unique only to Everest, dual air chambers, exhaust vents and additional insulation material diffuse and redirect heat away from the work top preserving its structural integrity. Equipped with the Blizzard R290 system, a fully self-contained and detachable condensing unit which uses natural, environmentally friendly, EPA-compliant R290 refrigerant with zero (0) Ozone Depletion Potential (ODP) and three (3) Global Warming Potential (GWP). Blizzard R290 is easily replaceable and requires no on-site brazing.
