Wildlife-repelling Device

https://korean-machinery.com///inquiry

[INQ. NO. 2311M09] Since its establishment in 2007, SUNAO Co., Ltd. has carried out projects with public organizations nationwide and is now importing and selling wildlife-repelling devices developed by Japanese technology.
SUNAO has collaborated in product development since two years ago, and DG603, one of the models released in 2021, is a popular product that is equipped with a timer and sold only in Korea.
As the company installs the device and carries out an on-site AS to repel wild animals, it has built up abundant practical experience. In addition, it is still cooperating with the HQs to improve product performance and develop new products.

The DG603, a wildlife-repelling device, runs for more than one month as it is powered by four D-type alkaline batteries. It is a semiconductor-based product that has a standard mode, a power mode, and a timer mode (which runs at a 12-hour interval).
After going through four-year-long experiments in mountainous areas, rice paddies, fields, and golf courses, it was developed and sold to customers in Japan and Korea for five years.
With frequencies ranging from 200 to 800Hz (the human vocal range), wild animals don’t like it at irregular intervals.

One device is able to prevent them from getting inside a radius of 3 to 40 meters. The device needs to be installed in and around the center of the crops to work properly and has a better and wider effect if there are no weeds or obstacles around.

Wildlife-repelling device with superior performance and effect
Because of its superior performance and effect, more than 10,000 units are sold in Japan and Korea each year, driving out wild animals such as elks, wild pigs, birds, bears, and others. As long as it is installed as instructed by the manual, it is an unrivaled product in terms of effectiveness (it has obtained a world patent).
Depending on which mode to use out of the three, it can run for one month, two months, or up to three months, powered by four D-type batteries. To get birds out, it should be installed at the 3rd height and at a place where there are no obstacles around for the sound to easily spread out.

Fuel-saving DeviceFor Automobiles

https://korean-machinery.com///inquiry

[INQ. NO. 2311M08] SAVE Inc., since its founding in 1988, has been carrying out product development, manufacturing, and global trading in six business fields.
SAVE recently proudly launched EnSave” on the global market based on its business philosophy of saving energy and the environment.
SAVE now has global branches and networks in more than 30 countries, and conducts close marketing cooperation with Korean governmental & public agencies, such as KOTRA, KITA, Gobiz, GBC, etc., enabling it to expand its business range worldwide.

Fuel-Saving Device for Automobiles using Wave Energy Catalyst
EnSave™, which has the effect of complete combustion and fuel-saving of a revolutionary automobile engine for economy, eco-friendliness; and safety, radiates the wavelengths of far-infrared wave energy generated from rare earth minerals into the engine, which decomposes the carbon component in the fuel. It acts as a catalyst to reduce fuel consumption and has the effect of improving fuel efficiency and reducing fumes by increasing engine power.

Realization of fuel and fume reduction at the same time
As a catalyst that increases the combustion efficiency close to complete combustion, it is able to reduce fuel and fumes at the same time. In addition, it is an eco-friendly product that removes harmful gases from the inside of the engine by acting as a catalyst in the pre-combustion stage inside the engine.
Unlike similar products that directly affect the existing car engine and internal components, EnSave™ can be installed easily within three minutes by simply putting it in an air filter. It is made of natural harmless materials such as rare earth, so it does not affect the life of automobile engines or parts. As there is no need for any electrical connection, it is safe to use without causing accidents like a vehicle fire.

In order to apply this effect most advantageously, when it is installed in a vehicle with a high fuel ratio, such as a long-distance vehicle, a bus, or a large distribution truck, the economic advantage increases. In addition, for older diesel vehicles with high carbon content in the fuel, it improves the smoke, fuel efficiency, vibration, and noise.
When installing EnSave™, it is better to consult with the manufacturer because the number of installations differs according to the displacement/horsepower of the vehicle used, etc.
