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.

SIX MINUTES

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.

CHARCOAL GRILL
VS BOOSTER GRILL

____________________________

The graph showing the heating up of an ordinary charcoal grill. Here you see the time and the grilling temperature. It takes some 20 – 30 minutes until you can start to grill, depending on how you ignite the grill. There are two problems: The heating up time is very long, and the temperature continuous to increase.

At the Röshults Booster grill, the heating up time is only some 5 – 7 minutes. 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.

At high infrasound level, the grilling temperature is above of 350 Centigrades. By lowering the infrasound level, the grilling temperature can be decreased down to 150 Centigrades.

THE DESIGN PHILOSOPHY

_____________________________

In the beginning of the design process we made some basic guidelines regarding in which direction the Booster Grill would go regarding look and function. We wanted it to stand out and take on a new look that communicates the function and suggests a connection to the aesthetics of classic Hi-fidelity objects.

But at the same time it was important for the Booster grill to fit in with the family of grills and outdoor furniture collection that Röshults presently consists of. We therefore decided to continue working with the same external dimensions and top-grate that all grill modules are based on, but we change the mid sections covering the acoustic parts and the front panel where the electric controls are placed. We went for an all stainless body and cassettes with a carefully selected perforated pattern for both airflow and aesthetics. Together with the distinct volume knob and power-light-source these alterations and details makes a fine bridge between this new breed and the existing collection.

THE POWER-LIGHT-SOURCE

The control knob and the power-light-source on the front panel makes the similarity to an amplifier and helps the user to get a sense of how it operates and when the power is switched on or off.

THE LEATHER GRIP

The grip on 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.

THE INVENTOR’S
OWN WORD

____________________________

Many years ago I discovered the impact of the infrasound on a combustion process. When charcoal burns normally it has a long flame. When the infrasound is put on, the combustion process changes dramatically. The intensity of the combustion increases, the flames become shorter and you cannot longer see any unburnt smoke at the top of the flame.

I discovered this phenome some 30 years ago. At that time I managed a project in Japan and I started to develop an infrasound grill there. We made a lot of different designs, but we run into a lot of problems; we had problems with noise, with vibrations and the electronics didn’t work. But the biggest problem was that the market was not prepared for new grill designs. Wrong timing so to say. I put the project on hold for many years.

Four years ago I imagined that the market was ready for a new advanced charcoal grill and I started the development from the beginning again. But with the difference that now I have a lot of experiences of enhancing combustion by infrasound in garbage incinerators and other combustion processes. I have made a lot of different test designs which now has resulted in the Röshults Booster Grill.

FAQS

_______________________________

1. WHICH CONNECTIONS REQUIRES THE BOOSTER GRILL?
It requires a power supply. The grill has Euro standard. When used in countries outside Europe, contact us for correct installation

2. WHAT CAN I USE TO IGNITE THE GRILL?
We recommend you to use Parrafin tablets, looftlighter or an electric charcoal starter. Warning! You may not use lighter fluid or liquid igniters.

3. WHAT TYPE OF FUEL CAN I USE TO MY GRILL?
Only charcoal should be used to the Booster Grill. For fastest ingition we recommend using regular charcoal. In order to provide the most consistent heat and predictable burn time while grilling place som briquettes on top.

4. ARE THERE ANY HEALTH RISKS USING INFRA SOUND? 
The Booster Grill uses infra sound. which provides low decibels like normal human ear not can perceive. The low frequencies in the Booster grill has no known risks to humans. It has no impact on those who use a hearing aid. There are no known risks for people with pacemakers.

5. CAN THE INFRA SOUND FROM THE BOOSTER GRILL BE HARMFUL TO ANIMALS?
Infra sound is not harmful to our pets.

6. HOW HOT COULD MY GRILL GET? 
At the maximum level of infra sound the grill can reach up to 400°. We recommend limiting the full effect of up to maximum 10 minutes.

7. WILL THE GRILL GET HOT ON THE SIDES? 
Yes it gets hot. Consider it as a regular charcoal grill. Children should be supervised.

8. WHICH COUNTRIES CAN THE GRILL BE DELIVERED TO?
The grill can be shipped to all countries. There might be some cases where an adjustment of the electrical connection is needed. Local deviations may occur. Check with us before ordering.

9 CAN I BUILD MY GRILL IN? 
Yes it can be built in. The grill should be at least 60 cm away from combustible materials. Notice: You must be able to access the emptying of the ash that occurs from the back.

10. DOES MY GRILL COME WITH A COVER?
When buying the Booster Grill the cover is not included. Covers are available as a separate accessory.

11. HOW FAR AWAY SHOULD MY GRILL BE FROM MY HOUSE?
The grill should be 24 inches away from any combustible material.

12. CAN I GET MY GRILL ASSEMLED?
The Booster Grill comes fully assembled with electrical connection via cord. We recommend contacting your local dealer about assembly services for assistance with the assembly process.

13. SHOULD I COVER MY GRILL?
We recommend covering your grill to keep it clean and protect it from the elements. The Booster Grill is weatherproof. The components in the grill can withstand outdoor environments and it´s IP classified with lowest IP65.

14. How does altitude affect my grill’s performance?
At altitudes above 5,000 ft, the level of oxygen in the atmosphere may be low enough to affect cooking times, but not the ability to cook delicious food. Typically, extending the cooking time of the food is all that is required to compensate for the reduced oxygen levels of higher altitude locations. For charcoal grills, it may be necessary to open all the vents on the grill fully to provide the maximum amount of oxygen possible to the coals.
