Founded in 1993, ADDTEC Co., Ltd. is a South Korean manufacturer specializing in automotive climate control and electronic components. ADDTEC’s main products include HVAC actuators, PTC heaters, and ECU & blower motors for ventilated seats.
ADDTEC is recognized as the first company in Korea to develop and mass-produce the auto flush door system. Continuing its tradition of innovation, the company is expanding into the electric vehicle sector with advanced solutions such as the driver’s refrigerant module and charge door module.

Motor Actuators
Motor actuators are largely divided into AFD actuators, HVAC actuators, and valve actuators.
AFD actuators are used to drive auto pop-ups for opening and closing auto flush door handles in automobiles and comes in two types — swing type and pop-up type.
HVAC actuator is used to control HVAC dampers to control cooling/heating, wind direction, switching of internal/external air, and temperature, and is applied to not only passenger cars but also commercial vehicles and special vehicles.
Valve actuator is used to control airflow for the HVAC system, but is mainly used as coolant valves that open and close valve to circulate external coolant.

BLDC Motor
BLDC motor is used to blow external wind for heat-exchange between the condenser and evaporator, and is mainly applied to buses.

 Driver Refrigerant Module
The driver refrigerant module is a control unit for EV thermal systems. It regulates refrigerant flow via valves and sensor feedback, working with the Vehicle Power Controller (VPC) to maintain optimal temperatures.

As a leading company in automotive electronic parts, specializing in components like seat ventilation ECUs, HVAC systems, blower motors, actuators (HVAC, valve, auto flush door handles), and PTC heaters, ADDTEC is growing into a global specialist in in-vehicle electronic components by developing and manufacturing these key products.
As a trusted supplier in the domestic market, ADDTEC is also actively extending its reach to global customers, delivering high-quality, reliable automotive components for the vehicles of today and tomorrow.
