The oil cooler is designed to heat the air and create a comfortable atmosphere in the cold season. The metal case contains oil heated to a high temperature by means of a heating element. Next, the radiator gives off heat to the room. The oil cooler is equipped with a thermostat, which allows it to automatically maintain the temperature set by the user in the room. A significant plus is that it has a low body temperature, due to which it practically does not burn out oxygen in the room.
