2 Operation

2.1 How the Phoenix D385 works

Your Phoenix D385 has two separate air streams that run through it – Process (Fig. 1) and Reactivation (Fig. 2).

Process Air Stream:

P1 – 385 CFM of air enters (12”flex) the top of the machine and...

P2 – ...water vapor from incoming air is deposited on the desiccant wheel.

P3 – 385 CFM of dry air exits (10” lay flat) the machine.

Reactivation Air Stream:

R1 – 75 CFM of air enters (6”flex) the lower-side of 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 – ...75 CFM of wet air exits (6”flex) the machine.

2.2 Avoiding Secondary Damages

The D385 is a powerful tool capable of removing a great deal of water from most environments. Care must be taken to avoid secondary damages of over-drying and or unexpected condensation.

Your Phoenix D385 removes vapor water from the incoming process air stream (Fig. 1) and transfers it to the outgoing reactivation air stream (Fig. 2). The reactivation exhaust air is hot and wet.

Take care to prevent the reactivation exhaust air stream from causing secondary damage due to condensation.

If the reactivation exhaust air stream cools below its dewpoint liquid water will condense inside the duct work creating puddles. If the reactivation exhaust air stream is not exhausted completely from the structure it can also cause secondary water damage.

Your Phoenix D385 does not produce liquid water internal to the machine. There is no condensate pump and no drain hose.

The D385 desiccant dehumidifier will continue to remove water from already dry, cold air. It is possible to over-dry objects and or structures.

Care must be taken to avoid secondary damages due to over-drying.

2.3 Universal Use Set-Up

When conditions warrant the use of a desiccant dehumidifier, use the set-up shown below (Fig. 3). This universal set-up will produce efficient drying, while avoiding secondary damages. The Phoenix D385 has been designed with the goal of being easy to use every time.
