Air Max Air Curtain
[INQ. NO. 2206M09] Air Max Air Curtains are installed on both sides of the entrance and discharge strong airflows in both directions, from left to right and from right to left. These curtains block airflow between the indoors and outside of the building.
It prevents micro-dust and harmful germs from entering the inside of the building. When cooling or heating buildings, unnecessary energy loss can also be prevented. It blocks the inflow of not only dust and odors but also small insects such as flies and mosquitoes. It also shuts off micro-dusts that adhere to the bodies of people entering the building. It sterilizes the indoor environments of building by using UV LED lamps. Only three seconds are required for a clean environment.

Any Clean Mat
Any Clean Mat blocks harmful substances. It automatically absorbs micro-dust, sand, and bacteria that adhere to shoes in the way that a vacuum cleaner does. It also sprays high-performance disinfectant to provide clean indoor air. Made of STS material featuring strength and durability, it can be used for a long time.
Although the initial cost can be a bit burdensome, maintenance is easy and simple with low-cost. Thus, in the long-term it will certainly deliver higher dust-removal effects at lower cost than carpets or sticky mats.
When a person approaches and steps on the mat, a sensor detects his or her movement, and operates the system. So, just walking on the mat blocks the entry of harmful substances.
Made of STS304 stainless steel, which is resistant to external impact and corrosion, it can be used for a long time without problems even in snowy or raining environments. It is easy to operate, and the dust-collecting box and disinfectant solution can be easily replaced without tools.
It not only blocks harmful substances such as fine dust, bacteria, and viruses from outside but also creates a comfortable indoor environment through disinfection/sterilization. Just three seconds are required for a clean environment.

Permanent Magnet Double Exciter Control Synchronous Generator

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

[INQ. NO. 2206M06] Suntech Co., Ltd., has been concentrating on production and R&D of rotary equipment since 1996. Suntech strives to satisfy customers with optimal performance and quality by combining its development of design and production technology of industrial generators, and the technological prowess it has accumulated over the past 26 years.
The permanent magnet double exciter control synchronous generator produced by Suntech is mainly used as a prime or standby generator by public institutions. It is a generator capable of high-efficiency power transfer that can provide the excitation electricity of the excitation rotor to the main rotor of the main generator unit directly by cable (Patent No. 10-1531932).
The double-structure exciting current control applying the permanent magnet improves the efficiency of the generator.


Durability against external factors is improved by separating the power line from the main output terminal. The electromagnetic force of the main field is generated by a permanent magnet to improve power-generation efficiency.
The main field output according to the fluctuating load is controlled by the exciter output to supply fast and stable voltage. By controlling the exciter output applying the permanent magnet through a cable, control stability and reliability are improved. High efficiency is maintained without a permanent magnet in the main rotor by optimization of a permanent magnet.


This generator is a prime/standby power source used independently for a long time, of which the electrical quality is clean. As its power-loss is small due to high efficiency, this product offers great fuel savings. Therefore, it is applied to places requiring a lot of cost in power supply due to lack of electricity infrastructure, such as islands, mountain refuges, disaster areas, or new town construction sites not yet connected by the Korea Electric Power Corporation — or to places operated on a long-term basis for stable power supply, or to places that require temporary power backup.
Suntech seeks to provide the best-quality products to customers with a mindset that customer satisfaction is its top priority. It is investing in development of unrivaled technology and equipment required for generator production, and aims to become a value-creating enterprise with ceaseless change and innovation.

[INQ. NO. 2206M03] Dong Yang EEC Co., Ltd., established in 1998, has focused on developing line-protection switches for the Korea Electric Power Corporation (KEPCO), beginning with inspection of the KEPCO distribution line protector.
As a result, Dong Yang EEC has become one of the few companies in Korea to have developed eco-friendly products such as epoxy insulated load break switches (pad mounted), polymer lightning arresters with lead wire, and eco-friendly pole mounted switches, as well as pad-mounted SF6 gas insulated load break switches, pole-mounted load break switches and automatic sectionalizing switches.
In addition, by establishing an R&D center, Dong Yang EEC ceaselessly strives to implement strategic policies and achieve quality-system assurance.


Eco Load Break Switch (LBS)
This was designed to improve the defects in the SF6 gas insulated load break switch and to enhance electric power distribution lines. Eco LBS consisting of cycloaliphatic epoxy material, is designed to be an explosion-free product, unlike SF6 gas insulated LBS with low gas pressure condition.
Eco LBS pursues not only the protection of the environment but also overcomes its fatal disadvantages. Eco LBS uses a vacuum interrupter and enhanced its switching capability, as well as eliminating any possibility of explosion by adopting the solid dielectric method. In addition, it is free from periodic gas leaks and gas refilling tests.

Polymeric Housing Surge Arrester
This product is a kind of overvoltage limitation. When overvoltage occurs, the voltage between two terminals of the surge arrester does not exceed the designated value, thus ensuring that the electric apparatus avoids damage caused by overvoltage, and thus enables the system to return to normal condition rapidly.
Dong Yang EEC’s polymeric housing surge arrester is a gapless-type that uses a ZnO element with excellent non-linear resistance coefficient characteristics.
With the ZnO element, the operation characteristics for multiple lightning and multiple surge, and anti-pollution features have been significantly improved. In addition, operating duty is available under a large current corresponding to discharge to withstand current rating.
