Thermos Stalgast 382200

A professional beverage thermos holds liquids at serving temperature without an external heat source. The flask uses a double-walled stainless-steel construction: an inner vessel holds the drink, while an outer shell surrounds it with an insulating air gap. This gap slows heat transfer, keeping hot drinks hot and cold drinks cold for hours. The method relies on conduction and radiation being blocked by the vacuum-like space, so no energy is consumed once the liquid is poured in.

To use the thermos, pre-heat or pre-chill the flask with hot or cold water for a few minutes, then empty it and fill with the beverage. Seal the lid tightly to prevent air exchange. The liquid remains at the desired temperature until the lid is opened for pouring. The flask is designed for repeated filling and emptying during a service shift, so it has a wide mouth that allows quick pouring and easy cleaning.

The flask is made entirely of stainless steel, chosen for its resistance to corrosion, odour retention and staining. The material is also approved for dishwasher cleaning, which simplifies daily upkeep in a professional kitchen. No internal parts need disassembly; the entire flask can be placed in a commercial dishwasher after use.

The 2.0 L capacity allows the flask to hold enough beverage for multiple servings, reducing the frequency of refills during busy periods. The volume is sized to fit under most counter-top taps and on standard worktops without overcrowding.

The thermos is categorised as a beverage service accessory in the Stalgast professional catering range.
