[INQ. NO. 1609M03] Ever since its founding in July 1993, ADDTEC, as a specialized company of automotive climate 
control components & electronic parts, has been manufacturing and delivering top-quality damper actuators of HVAC modules, water valve actuators, actuators for 2W ~ 4W control and electronic heater system components (PTC pre heater, seat heater control).
To meet the customer requirements in the automotive industry, it made committed efforts to acquire international standard certificates (ISO/TS16949, ISO14001 and ISO9001). Among its customers are KB Auto Tech, Daehan Calsonic, Denso, Dorman products, Robertshaw, MCC, WARN and Bergstrom.
In the upper category where flagship items lead the company’s development in markets domestically and abroad, the company’s damper actuator takes the most upper location among various kinds of its products that are ready to be sold. It is because of its comparatively superior merits to allure more potential buyers than the remaining players. It controls dampers of heater units and blower units at HVAC system of vehicle to control temperature, air direction and air circulation inside of vehicles.
Mode and temp actuators are installed in the heater unit, and an intake actuator is installed in the blower unit. The intake actuator is designed to control incoming wind direction to move damper or circulating inside air. The mode actuator is to control incoming wind direction in 5 modes-vent, b/l, foot, def/foot, def. Temp actuator is used for inside temperature adjustment (aircon/heater).

The engine mount from the company is popular in the industry as it can effectively support the engine between the car body and the engine, and reduce vibration and noise coming from the engine at the same time. Accordingly, vibration isolation for vehicle noise is important. And also, Haeun Tech importantly considers in the process of design of engine mount that it has to be able to support the weight of the power train, limit the displacement from external shocks, and protect the power train from outside shocks.
Located in the heart of Seoul, Insa-dong Street is one of the most memorable attractions in Seoul and represents the focal point of Korean traditional culture and crafts. Stores in Insa-dong specialize in a wide variety of goods that can only be purchased or appreciated in Korea: hanbok (traditional clothing), hanji (traditional paper), traditional teas, pottery, and folk crafts.
basically meeting the demand of customized supply and service. The great advantage of HF (High Frequency) welding is the speed of welding. In comparison with high frequency, in all other kinds of welding methods (with filaments, hot air or infrared radiation) the heat has to be added from the outside. It means the heat must first penetrate the material in order to make it plastic enough to form a weld.
Widely applicable for vacuum packing, food packing, laboratories, medical instruments, vacuum molding, vacuum drying and suction transfer, MVO-630 has a nominal displacement of 630m3/hr at 50Hz or 760m3/hr at 60Hz. Weighing approximately 670 kg, the model off ers a nominal motor rating of 15KW at 50Hz or 18.5KW at 60Hz.
MVO-630 is made under the company’s strict qualitycontrol according to ISO 9001 and CE standards. It is easy to maintain due to its simple design and air-cooling system.
For customer satisfaction, the company has operated its own research institute authenticated by the Korean government. Equipped with CAD/CAM systems, the institute has constantly developed innovative technologies concerning reverse engineering, high-speed machining and 5-axis machining fi elds.
