INFRA SOUND TECHNOLOGY
Röshults Booster BBQ Grill is a charcoal grill ignited by infrasound.
Infrasound, also known as low frequency sound, cannot be heard by human beings. Yet the infrasound is very powerful. With infrasound technology, we control the movements of molecules each brick of charcoal. Pushed with energy, the molecules move faster, making the heat increase and the glow grow stronger. All within seconds.

With Röshults Booster BBQ Grill, you can start barbecuing faster than ever before. The rapid ignition process results in a perfect glow, after only 3-5 minutes.
The infrasound technology gives you full control of the intensity of the heat, enabling you to instantaneously achieve the perfect temperature for your barbecuing.
Röshults Booster BBQ Grill is not only faster than an ordinary charcoal barbecue, it is also safer and more environmentally friendly. The barbecue is ignited without the use of lighter fluid, which probably will be banned in Europe within a few years. In addition to this, the smoke emission is minimized and any unexpected flaming is prevented.
Thanks to the infrasound, the grill is heated in a few minutes. Just like a gas grill. The food can be put on the grill within some 6 to 7 minutes.
The grill can be lit without using lighter fluid, which probably will be banned throughout Europe within a few years. Use a couple of small paraffin bags to light the grill.
The enhancement of the glow bed depends of the power, or volume, of the infrasound. That makes it possible to regulate the intensity of the glow bed and hence the grilling temperature.

ORDINARY CHARCOAL GRILL
THE BOOSTER GRILL
It usually takes between 5 and 10 minutes to light an ordinary barbecue. Once ignited, the barbecue needs another 20 minutes to heat up. All in all, an ordinary charcoal barbecue requires roughly 25-35 minutes until the temperature is fit for barbecuing. The slow ignition process is not the only problem an ordinary charcoal grill has. As the graph shows, the temperature continues to steadily increase, reducing the chance of achieving perfect results.
In contrast, Röshults Booster BBQ Grill can reach temperatures up to 400°C in only 5 minutes. In this time, an ordinary charcoal barbecue might not even be ignited yet. The intensity of the heat is easily regulated, as the Booster BBQ Grill operates with the use of infrasound technology. By increasing or decreasing the level of infrasound, the temperature can be altered instantaneously, allowing for perfect barbecuing conditions throughout the entire session. Consequently, the results are impeccable.
INFRA SOUND TECHNOLOGY
The Röshults Booster Grill is a charcoal grill where the glow bed is agitated by inaudible infrasound. Infrasound is sound with extremely low frequencies. A human being cannot hear those low frequencies, but still the infrasound can be very powerful. With infra-sound technology, we can control the movements of the molecules in the layers of charcoal. We push them to move faster, making the heat rise and the glow grow stronger. All within seconds.
FORM & FUNCTION
FORM & FUNCTION
THE CONTROL KNOB
By turning the control knob, you can easily regulate the level of infrasound. The temperature of the barbecue is adjusted instantaneously.
Taking airflow as well as aesthetics into account, parts of the body are covered with a carefully selected, perforated pattern of stainless steel.
THE DESIGN PHILOSOPHY
“In the beginning of the design process, we established some basic guidelines regarding the Booster Grill’s appearance and function. We wanted it to stand out with a new look, communicating its function and suggesting a connection to the aesthetics of classic Hi-fidelity objects. The work by the great German designer Dieter Rams in the 60s and 70s served as a source of inspiration.
At the same time, it was important that the Booster BBQ Grill would fit in with the present family of barbecues and outdoor furniture collections of Röshults. Consequently, we decided to continue working with the same external dimensions and top-grate that the other grill modules have. We also decided to make an all-stainless body. However, we modified the mid section covering the acoustic parts, and the front panel where the electronic controls are placed. We added cassettes with a carefully selected, perforated pattern, taking airflow as well as aesthetics into account. Together with the distinct volume knob as a power-light source, these alterations and details make a fine bridge between this new product and the other collections of Röshults.”

Designers of Röshuls Booster BBQ Grill
THE POWER-LIGHT SOURCE
Similar to an amplifier, the control knob in combination with the power-light source guides the user in how the barbecue operates. The construction indicates the barbecue’s function and shows when the power is switched on or off.
THE LEATHER GRIP
The grip of the cooking grate is made of premium full-grain leather, carefully selected for just the right feeling. As it ages, the leather takes on a unique patina, demonstrating its high quality and durability.
“Many years ago, I discovered the large impact that infrasound has on a combustion process. When charcoal burns, it normally has a long flame. However, infrasound changes the combustion process dramatically. The intensity of the combustion increases, the flames become shorter and unburnt smoke on top of the flames is no longer visible. All in all, infrasound has a significant effect on the combustion of charcoal.
I discovered this phenomenon perhaps 30 years ago. At that time, I was managing a project in Japan and I started to develop a prototype of an infrasound barbecue there. We made many different designs, but we also ran into a lot of problems. We had problems with noise, with vibrations, with electronics that didn’t work… However, the biggest problem was that the market was not prepared for new grill designs with advanced technology. It simply was the wrong timing. And so, I put the project on hold for many years.
Four years ago, I decided to continue with the project of making a new and more advanced charcoal barbecue, with sophisticated technology. The market was ready. Starting from the beginning again, I now had a lot of experience in enhancing combustion processes with the use of infrasound. After developing the construction to perfection, and after many tests and evaluations, it has resulted in the Röshults Booster BBQ Grill.”

14. How does altitude affect the performance of my barbecue?
At altitudes of 1800 meters/5000 ft, the cooking time may need to be extended in order to compensate for the low level of oxygen. However, the quality of the food is not affected. The ability to cook delicious food is further enhanced by opening all the vents of the charcoal grill, maximizing the airflow to the charcoal.
