True’s horizontal bottle coolers are designed with enduring quality and value. Our commitment to using the highest quality materials and oversized refrigeration assures colder product temperatures and years of trouble-free service. Factory-engineered, self-contained, capillary tube system using environmentally friendly R290 hydrocarbon refrigerant that has zero (0) ozone depletion potential (ODP), & three (3) global warming potential (GWP). Forced-air cooling. Positively guided airflow cools bottles on top first. The evaporator coil virtually runs the length of cooler for balanced temperatures throughout the cabinet. High capacity, factory-balanced refrigeration system that maintains cabinet temperatures of 33°F to 38°F (.5°C to 3.3°C) for the best in food preservation. Exterior – all stainless steel countertops, lids, cabinet front and sides, and back. Interior – long-lasting, heavy-duty galvanized steel. NSF/ANSI Standard 7 approved for packaged and bottled products. The evaporator is epoxy-coated to eliminate the potential for corrosion. Heavy duty, 10 mil thick pure grade PVC coated adjustable bin dividers. The entire cabinet structure is foamed-in-place using a high-density, polyurethane insulation that has zero ozone depletion potential (ODP) and zero global warming potential (GWP).
