Durability and Performance

The Deltech WM heatless desiccant air dryer is the smallest dryer ranging in capacity from 7-50 scfm and the choice of -40°F to -100°F pressure dew point performance as standard. The WM is wall mounted to save space and comes already assembled and ready to be plugged in.

As a heatless dryer, the WM has the least amount of maintenance cost of any dryer.  The desiccant last much longer in heatless air dryers than it lasts in heated air dryers.  This saves the user money by not having to buy replacement desiccant as often.

The WM also uses two alternating vessels that allow for continuous efficient use as one vessel dries the air while the other uses purge air to get rid of the water molecules in the desiccant of the other vessel.  The WM has a simple operating procedure with a timer either set for a 4 minute or 10 minute cycle.

Control:

• -40°F dew points...choose the 10 minute cycle mode (factory setting)
• -100°F dew points...choose the 4 minute cycle mode
• Power On Light
• On/off toggle switch
• Left Tower pressure gauge
• Right Tower pressure gauge
• 6 foot grounded 115 vac cord set included

Design:

• Energy saving heat of adsorption is retained to reduce operating costs
• Controlled repressurization rate prevents desiccant deterioration
• Heavy-duty purge muffler delivers quiet operation
• Removable stainless steel support screens won't corrode
• Upper and lower stainless steel air diffusers protect valves and prevent channeling
• Premium quality activated alumina for dry air and long life

Easy Installation:

• Shipped with full charge of desiccant
• Completely assembled, piped and wired
• Simple set up
  1. Mount cabinet
  2. Pipe air-in, pipe air-out
  3. Plug in the power

How the WM Series Works

See Figure 1. Compressed air enters the dryer and is directed to Tower 1 by valve (A) and then to the dryer outlet through shuttle valve (B). A portion of the dried air is throttled to near atmospheric pressure by means of orifice (C). This extremely dry, low pressure air flows through and regenerates the desiccant in Tower 2 and is exhausted through purge/repressurization valve (D) and exhaust muffler (E) to atmosphere. After a set time, the automatic solid state timer closes purge/repressurization valve (D) allowing Tower 2 to repressurize slowly. At the end of 5 minutes (when operating on a 10 minute cycle, 2 minutes on a 4 minute cycle), valve (A) shifts and purge/repressurization valve (D) re-opens. See Figure 2. The main air flow is now dried by Tower 2 while Tower 1 is being regenerated.
