Ultrasonic repeller Deramax-Profi

The Deramax-Profi repeller is used to protect indoor and outdoor spaces from martens, rodents and shrews. The device is completely safe and noiseless for humans. Pests are permanently bothered by the ultrasonic signals of the repeller and leave the protected area in a short time. The operation of the device is ecological without the use of chemicals.

Automatic change of frequency and power:
The Deramax-Profi repeller has an automatic change of the ultrasonic frequencies used, which are optimized for the given type of pest. At the same time, there are controlled changes in the repeller's power. Coordinated changes in frequency and power significantly contribute to increasing the effectiveness of the repeller and reducing the possibility of pests becoming accustomed to the repeller's signal.

Resonant amplification of the ultrasonic signal:
The Deramax-Profi repeller uses resonant amplification of the signal, which is important for achieving the highest possible performance with the lowest possible energy consumption. We calibrate the frequencies generated by the electronic circuits of the repeller with the resonant frequencies of the used piezo transducers (ultrasonic "emitters") within each production series.

Power supply of the Deramax-Profi repeller:
The Deramax-Profi is a repeller powered by a mains power supply (socket adapter). The power supply is not included.

Target group of pests:
Martens, mice, rats, shrews, weasels.

Resistance of the repeller:
Indoor and outdoor use. The repeller is resistant to water, snow, humidity, dust, high temperatures and frost (- 25°C to + 80°C).

Safety of the Deramax-Profi scarecrow:
From the point of view of its effect on humans, the Deramax-Profi scarecrow does not disturb its surroundings with unpleasant noise, it is completely silent and safe. It meets the legal limits set for the maximum level of ultrasound. Our internal rules go beyond the scope of applicable laws and take into account current medical scientific work and WHO recommendations for ultrasonic signals transmitted through the air. At the same time, this marten and rodent scarecrow has no negative effect on common domestic or farm animals, such as dogs, cats, horses, poultry, exotic birds, etc.

Comfort of operation:
The device does not need to be set up in any way, it works completely automatically.

Placement of the scarecrow:
A common solution for placing the scarecrow and usually the most practical solution, especially when used indoors, is to place it on the ground in one of the corners of the protected area with the front part directed towards the center of the protected area. However, it is also possible to attach the repeller using screws or double-sided adhesive tape to a fence, wall, post, window, door, etc., which is most suitable for use outdoors. In this case, we also recommend directing the front of the repeller to the center of the protected area. For more information on suitable placement, see the page All about pest repellers.

Effective range of the Deramax-Profi repeller:
The maximum effective distance in front of the repeller is up to 28 meters. The effective area is up to 650 m². The effective angle of coverage is 180 degrees. The repeller therefore not only has high performance, but the special design of the device ensures that a very wide effective angle of coverage of 180 degrees is achieved, and even at the limit of the declared angle of coverage (i.e. outside the main direction of signal radiation), the repeller still generates at least 80% of the declared sound pressure level. The ultrasonic signal of course spreads beyond the stated angle of 180 degrees, but the efficiency is lower here, and therefore, for the sake of objectivity, we indicate an effective angle of "only" 180 degrees.

Number of repellers in one space:
Any number of ultrasonic repellers can be placed in one place and their signals do not negatively affect each other. On the contrary, more repellers are commonly used to protect, especially larger or more structured spaces, because a larger number of repellers (repellers) installed in one place means significantly higher penetration of the protected space by the ultrasonic signal and the overall efficiency increases.

Official measurement:
Sound pressure level of the Deramax-Profi repeller: 106 dB. LAmax value. Effective (TrueRMS) value of the sound pressure level. The measurement was carried out within the TÜV SÜD testing laboratory.
