The Stainless Tumbler from Zojirushi’s SX-DD series is the perfect mate to your hot and cold beverages. The vacuum insulation technique used to create the tumbler allows the beverage to preserve its original temperature for hours meanwhile keeping the exterior of the product cool to the touch, even when filled with scorching hot drinks or condensation-free while carrying frosty cold beverages, surpassing traditional mugs and cups in practicality and style.
The vacuum insulation technology keeps the temperature of the beverage at a constant for hours by completely removing the air from in between the two layers of stainless steel that make up the walls of the tumbler. By doing so, a vacuum is created disabling any heat from travelling through air thus creating an advanced way of preserving heat. To strengthen this retention of temperatures, the insulated products feature a layer of copper or aluminum which help reflect the heat. The insulation of the body of product is aided by an airtight, insulated lid. The heat retention achieved through this technique helps keep the hot beverages still hot (rather than lukewarm) and cold beverages cool (rather than room temperature) for hours after filling when compared with products using either foam or double wall insulation.
A production ingenuity of Zojirushi vacuum insulated products, the brand’s proprietary SlickSteel® (electrolysis polishing method) is used in manufacturing the tumbler to achieve the sleek interior. With this technique, the inner surface becomes highly resilient against corrosion and stains making it both durable and easy to clean without having to worry about unsightly markings that occur over time. Another special manufacturing detail of the tumbler comes in the form of a round, smooth rim of the model’s wide mouth which makes the SX-DD easy to fill and clean and permits comfortable drinking.
