Main Materials Of Commercial Water Dispensers

Commercial water dispensers are primarily made of stainless steel, with a particular emphasis on food-grade 304 stainless steel to ensure durability, corrosion resistance, and drinking water safety.

 

Inner Tank and Water Container: Generally made of 304 food-grade stainless steel. Some models use 201 stainless steel (such as some Chigo models), but 304 is superior, offering higher corrosion resistance and food safety.

 

Outer Shell: Mostly made of stainless steel (including brushed stainless steel or 304 stainless steel), balancing aesthetics and durability.

 

Heating Element: Commonly uses 304 stainless steel heating elements. High-end models may use copper heating cores or a combination of nickel-chromium wire heating elements.

 

Filter Cartridge and Piping System: Some models are equipped with RO reverse osmosis or ultrafiltration systems. The piping uses a fully enclosed design, and the materials are mostly food-grade plastic or stainless steel to prevent secondary contamination.

 

In summary, 304 stainless steel is the most core and commonly used material in commercial water dispensers, especially for the inner tank, water container, and water outlet components that come into direct contact with hot water, meeting relevant national hygiene and safety standards.
