Stainless Steel Evaporator for Chilling And Freezing Applications

Stainless Steel Evaporator for Chilling And Freezing Applications

Working Principle

Direct expansion: The liquid refrigerant evaporates in the evaporator and absorbs the heat of the medium to be cooled (e.g. air or water), thus realizing the cooling or freezing effect. The pressure inside the evaporator is low, which enables the liquid refrigerant to boil and evaporate at a low temperature.

Full-liquid type: the evaporator is filled with liquid refrigerant, the cooled medium flows inside the tube and exchanges heat with the liquid refrigerant outside the tube, and the liquid refrigerant absorbs heat and evaporates into gaseous state.

Structural characteristics

Heat exchanger tube: usually made of stainless steel, such as 304 or 316 stainless steel, with good corrosion resistance and thermal conductivity.

Shell: generally made of stainless steel plate, can withstand a certain pressure and temperature, to protect the internal heat exchanger tube and other components.

Refrigerant distribution device: Ensure the refrigerant can be evenly distributed to each heat exchanger tube to improve the heat exchange efficiency.

Advantages

Strong corrosion resistance: able to resist the erosion of corrosive substances that may occur in the cooling and freezing process, suitable for a variety of harsh environments.

Good thermal conductivity: stainless steel has a high thermal conductivity, can quickly and effectively transfer heat, improve cooling and freezing efficiency.

Good hygiene performance: smooth surface, not easy to breed bacteria and dirt, easy to clean and maintain, in line with the strict requirements of food, medicine and other industries on health.

Long service life: under normal use conditions, the stainless steel evaporator has a long service life, reducing the frequency of equipment replacement and maintenance.

Application fields

Food and beverage industry: used for food refrigeration, freezing, preservation, such as cold storage, freezer, ice cream machine.

Chemical industry: used for cooling and freezing various chemical substances in chemical production, such as cooling of reaction kettle, freezing storage of chemical raw materials, etc.

Pharmaceutical industry: Used for refrigerating and freezing preservation of medicines, as well as cooling and freezing process in pharmaceutical production.
