3 Operation
3.1 How the Phoenix D850 works
Your Phoenix D850 uses two separate air streams – Process
(Fig. 1) and Reactivation (Fig. 2). Moisture is transferred from
the incoming process air to the outgoing reactivation air. It is
exhausted from the structure as water vapor, so there is no
drain hose or condensate pump.
Note: Check for airflow at all inlets and outlets. DO NOT run
unit if no airflow is detected.
Process Air Stream (Fig. 1):
P1 –
850 CFM of air enters (18” or 12” flex) the machine
and...
P2 –
...water vapor from incoming air is deposited on the
desiccant wheel.
P3 –
850 CFM of warm, dry air exits (10” layflat) the
machine.
Reactivation Air Stream:
R1 –
225 CFM of air enters (6”flex) the machine and...
R2 –
passes over the heater coils.
R3 –
Water vapor is picked up from the desiccant wheel by
the hot air and...
R4 –
...225 CFM of warm, wet air exits (6”flex) the machine.
3.2 Avoiding Secondary Damages
Care must be taken to avoid damage caused by unexpected
condensation, over-drying, or overheating.
Take care to prevent the reactivation exhaust air stream
from causing secondary damage due to condensation.
The reactivation exhaust air is warm and moist. If it cools
below its dewpoint, it will condense inside the ducting,
creating puddles. Minimize this effect by using the shortest,
straightest duct run possible and insulating the duct if
necessary. Slope the duct away from the D850 to prevent
internal damage from condensation running back into
the machine. If the reactivation exhaust air stream is not
exhausted completely, perhaps due to leaks in the ducting,
it can also cause damage to the structure if it condenses on
cool surfaces.
