Why does the heat exchanger air temperature feel cooler than a direct flame burner?
The DRYAIR Heat Exchanger has been designed to eliminate “Hot spots” in a building by using high air flow. Example: a direct flame burner of equivalent size or rating will output 236 L/sec of air at 205 °C while a DRYAIR PHE-60EU portable heat exchanger will output 1,085 L/sec of air at 49 °C. This is an equal amount of KW output, but the effect is different. The low air flow and high temperature of the direct flame burner will create a hot spot around itself and cause an uneven distribution of heat throughout the building. The DRYAIR fan is designed to move much more air at a lower temperature and creates a more even temperature throughout the building without the use of additional fans.
