It ensures that the exhaust air that needs to be removed from the environment is discharged to the outside environment, as well as the fresh air needed by the indoor environment through the same device.

While expelling the cooled air in the environment in the summer, it cools the fresh air to be taken in. In the winter, while expelling the hot air in the environment, it provides energy savings by heating the fresh air to be taken in.

Heat recovery units save energy by reducing the load on the air conditioning system, thus returning the installation cost to the operation in a short time.
