The secret to Drink Now Technology™ is BURNOUT’s Dual Chamber Design and HeatZorb™
Vacuum mugs have a single vacuum chamber: two stainless-steel walls between which is a vacuum. Vacuums are devoid of matter, meaning there is nothing to transfer heat. That’s how they keep your coffee hot. The only place to lose heat is through the lid. BURNOUT features Dual Chamber Design, two chambers configured from three layers of 18/8 stainless steel. The first is an aerospace-grade vacuum chamber to the outside of the mug, while the second chamber resides to the inside of the mug and is filled with HeatZorb™, a special wax-like, bio-based substance that quickly absorbs and stores the heat from the coffee, bringing it to optimal drinking temperature (approximately 140°F) in just minutes. HeatZorb™ is technically referred to as a “phase change material” (PCM), meaning it is calibrated to change from a solid waxy substance to a liquid at a designated temperature (140°F). It is at this temperature that heat absorption stops and your coffee enjoyment begins. And because the HeatZorb™ chamber is surrounded by a vacuum chamber on one side, and coffee on the other, and the material has stored a lot of thermal energy, the transfer of this heat back to the coffee, to keep it at a zone of perfect drinking temperature. So, no burned mouth, coffee that you can drink right away and coffee that stays at that optimal drinking temperature for many hours!
