Restoring fresh, clean air and
a comfortable indoor environment is a necessity for life.

This is Sungil, a company specializing in waste heat recovery ventilators.
We are diversifying our business areas to become a specialized company based on the management philosophy of putting customers first.
Most modern people spend more than 80% of their day in highly enclosed rooms to save energy, but these enclosed rooms have been shown to be more than three times more polluted than the outside air due to difficulty in air circulation.
The best way to combat this is through ventilation.
Clear, clean air and restoring a comfortable indoor environment are now essential conditions for living.
The installation of waste heat recovery ventilators that can save energy beyond the concept of simple ventilation is an essential equipment that is also mandated through relevant laws and regulations.
Sungil will work with our customers with our valuable experience and differentiated technology in environmental pollution control and energy saving to create a cleaner and healthier indoor environment.
In addition, Sungil's executives and employees will provide you with the best quality and service based on creative technology in all areas of design, construction, and after-sales management.
We will be a company that provides satisfaction with the best quality and best service.
