Key Info
A specially designed cigarette was inserted into a
battery-powered heater equipped with an array of eight blades that heated the tobacco and minimized burning during puffing.
User Experience
A flow sensor initiated the heating circle
for each of the blades as the puff was detected.
The design allowed for greater control
of the available heat resulting in lower
temperatures and less combustion as
compared to combustible lit-end cigarettes.
Experience limited to 8 puffs per cigarette.
*Name in regulatory submissions
Heating Technology
External heating.
The heater was equipped with an array of eight blades made from an iron-aluminide alloy, one blade for each of the eight
possible puffs per cigarette.
With this design, the tobacco reached a peak temperature of approximately 500 °C.

Introduces the bladeless heating technology
ROUNDHEAT TOBACCO SYSTEM™:
a flexible heater surrounds the tobacco stick
and heats its external surface.
With a stronger focus on robustness and ease-of-use,
the all-in-one design allows for a low-maintenance
and easy to use experience.
User Experience
ROUNDHEAT TOBACCO SYSTEM™
Tobacco plug made from tobacco leaves cut in small pieces and processed specifically for the use of Roundheat Tobacco System™. The tobacco stick has a front plug to assist correct use and improve cleanliness, and a cardboard tube with air inlets to enhance aerosol formation.
The resistive heater is made of flexible polyimide stainless-steel tracks wrapped around a stainless-steel tube, with an insulated thermal casing around it.
When the tobacco stick is inserted inside the holder and the device is activated, the tobacco plug is heated externally by the electronically controlled resistive heater wrapped around the stick.
