Attention compressed air equipment distributors! You need total application versatility. Deliquescent air dryers have no moving parts or power requirements. In some cases these qualities are of unique and overriding value. There are times when no other dryer technology is quite right. That’s when you call Van Air Systems.

Here are five clues that it might be a good application for a “deli.”

1. The installation is outdoors or in a minimally conditioned building.

We all have a customer who keeps the air compressor in a shack outback. When it rains the enclosure might leak. When the wind blows dust gets everywhere. When it’s cold the customer puts a heat lamp on his compressor to make sure it starts up. You know the type. I’ve been to this kind of operation in a lot of industries. Examples can include: lumber yards, saw mills, metal fabricators, equipment yards, concrete plants, rail yards, mines, quarries, paint shops. The customer wants dry compressed air. A refrigerated dryer won’t survive long in these conditions. A regenerative desiccant dryer is too complex and too expensive and too wasteful. This is a great application for a deli dryer. Pro tip: In the winter switch this customer to 10BF desiccant to get a below freezing dew point.

2. The air system is portable.

Not every air system sits still. Truck mounted and towable diesel air compressors are everywhere. Is the air being used to spay paint, sandblast, run pneumatic pumps, recharge air brakes, or any other process that is sensitive to moisture? If so, this just might be a deli dryer application.

3. The operating environment has a lot of dust.

We have a D12 air dryer running at a shop that grinds limestone for monuments. Spend five minutes in this place and your eyebrows will be powdered white. Even though the compressor is in a room with inlet air filters the limestone dust inevitably intrudes. Ambient dust coats the condenser on a refrigerated dryer, making the deli dryer a compelling alternative.

4. The air usage is highly intermittent.

For whatever reason this customer only needs dry compressed air in brief or very intermittent bursts. For most of the day the air compressor is off. The receiver tank sits there fully charged, cool, and ready to deliver air. Putting a deli dryer after the receiver tank is an excellent and economic solution. Dry-O-Lite consumption will be close to nil, as will maintenance costs.

5. There are electrical restrictions.

Challenges related to electrical power come up often enough. Not enough amps on the circuit? No power at all? Hazardous area electrical classification that would require a costly enclosure? Get around all of these problems with a deli dryer.
