Application
SGR-420T tropical display cooler can work normally at 43℃ and is mainly applied in tropical area. It has a storage volume of 420 L and has 4 layers of display shelves. The power is 280 W. This model of fridge is mainly used for the preservation, display and sale of food, drinks, vegetables and fruits. It is widely applied in shopping malls, supermarkets, and convenience stores.

Materials of SGR-420T tropical display cooler
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 used high-quality copper tube condenser is resistant to corrosion, high temperature and high pressure, so it's very sturdy and durable.
• SGR-420T display cooler is equipped with a high-quality compressor which is less noisy, highly resistant to temperature, environmentally friendly and energy saving.
• Swivel casters are equipped on the bottom and they can rotate by 360 degree, so you can move the fridge conveniently.
• The inner shelves can be adjusted to any height according to the sizes of objects. So it's convenient to preserve objects and can show a better display effect.
• The canopy and inner lights are both LED tubes whose light is so soft that it doesn't hurt eyes. Besides, LED light is also energy saving.
• A safety lock is equipped, 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-420T display cooler. 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.
