The Nexus Fridge NX-235 Red/Flower from Nexus Brand is efficient, durable and reliable too. It consists of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical). This transfers heat from the inside of the fridge to its external environment. The fridge then cools to a temperature below the ambient temperature of the room. The Nexus Fridge NX-235 Red/Flower maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).  The refrigerator also comes with an icebox which is used in cooling food and also a freezer for food storage.
