The curves on the next page shows the characteristics of the dryer. By measuring
or calculating the back pressure of the outlet pipe it is hereby possible to find the
corresonding air flow into the room and through the dryer and exhaust.
It is important that the dryer has the correct air volume compared to each dryer’s effect.
If the air flow is below the minimum, the dryer will be forced to switch the heating off thus
prolonging the time it will take to dry the load.
An air flow above the needed is unnecessary and can result in a cold laundry room and
noise from the piping and outlet and in extreme cases prolonged drying time.
The condensate dryer does not have ventilation (evacuation) into the open.The air is
circulated in a closed system between the dryer and condensing unit.
