Application
SGR-220N glass door display fridge isn't equipped with light box. It has 3 layers of display shelves and its storage volume is 220 L and the power is 160 W. This model of fridge is mainly used for the preservation, display and sale of food, drinks, milk, vegetables and fruits. It is often used in shopping malls, supermarkets and convenience stores.

Materials of SGR-220N display fridge
Inner material
The inner material is pre-painted aluminum sheet, which is highly resistant to acid, alkali and corrosion.

Outer material
Pre-painted steel sheet is used as the outer material due to its sturdy property and the advantage of long service life.

Glass door
Two layers hollow tempered glass is used to produce the display fridge door, which has the function of efficiently demisting, so that the objects inside can be shown clearly. The material of door frame can be plastic or aluminum alloy.

Features of SGR-220N display fridge

Swivel casters are equipped and they can rotate by 360 degree, so you can move the fridge conveniently. Besides, there are adjustable leveling feet on the bottom and the fridge can be adjusted to a horizontal level and kept from falling.

Plastic coated fridge shelves are used to preserve foods, showing better display effect. The shelves can be conveniently adjusted to any height according to the sizes of objects.

SGR-220N display fridge is equipped with a safety lock, which can reduce unnecessary losses. So it's much safer and you don't need to worry about its safety.

Finned evaporator and a set of air duct parts are equipped in this SGR-220N display fridge. The fan makes the air which is cooled in evaporator form an up-down cycle to refrigerate the cabinet. Since air in is cooled, it will not absorb water from the food stored, so frost can be avoided. The scientific and effective configuration enables the whole stable refrigeration system to work steadily, and meantime, it features low carbon, energy saving and environmentally friendly.

Inner components

Fan
A fan is equipped to cool objects in the cabinet more quickly and more uniformly compared to direct cooling system. In addition, it is helpful for automatic defrosting and can avoid freezing effectively.

Aluminium finned evaporator
Liquid refrigerant vaporizes and evaporates when flowing through the cooling tubes of evaporator. This is a process of heat consumption and then the temperature in cabinet decreases gradually so that the food inside can be frozen or cooled.

Compressor
The low-pressure refrigerant steam flowing out of the evaporator is compressed in the compressor and then the steam pressure is increased to the condensing pressure corresponding to condensing temperature. Under this circumstance, the refrigerant steam can be and liquefied and condensed at normal temperature.

Aluminium finned condenser
As a heat exchanger, the condenser can enable the steam refrigerant to release heat to environment medium and then be condensed to liquid. Then the refrigerant can be evaporated in next turn and be used again and again.
