HB Series

Van Air HB Series heated regenerative compressed air dryers are designed to protect pneumatic equipment and processes from the harmful effects of moisture within compressed air lines. When you don't have compressed air to spare, Van Air HB Series air dryers provide the solution requiring no purge air for adsorbent desiccant regeneration.

HI Series

Van Air HI Series internally heated regenerative compressed air dryers utilize a multiple-element heater located within the desiccant tower to heat the purge air for the regeneration of the adsorbent desiccant. The -40° F / C dew point achieved with these compressed air dryers virtually eliminates internal pipe corrosion, adding years to your air system piping.

HP Series

Van Air HP Series heated purge regenerative compressed air dryers provide a low -40° F/C pressure dew point for superior air line moisture protection while offering the efficiency of convection-heated desiccant regeneration with minimal purge air

HL Series

Instead of using an external heat source, the HL Series heatless regenerative compressed air dryer utilizes a percentage of dry purge air to regenerate the moisture laden desiccant.

HLS Series

The little brother of our highly recommended HL Series heatless regenerative compressed air dryer, our HLS Series air dryers provide a low -40° or -100° F dew point between 55 and 150 SCFM.

MHL Series

Van Air MHL Series mini heatless regenerative compressed air dryers provide a -40° or -65° F dew point while operating between 10 to 25 SCFM. With simple twist-off desiccant cartridges, the MHL Series compressed air dryer is dependable and very easy to maintain.

For air line protection, Van Air RD Series refrigerated compressed air dryers combine the newest technology in heat transfer with a proven refrigeration system to keep your pneumatic equipment running at peak efficiency. Providing a constant 35 - 38° F dew point and low initial cost, an RD Series refrigerated air dryer provides the best combination of performance and economy.

All the components of an RD Series refrigerated compressed air dry are housed in a powder coated cabinet to ensure a long useful life. All units include a refrigerant analyzer light, non-cycling refrigerant compressors, a compressor run light, and a built-in drain.

A capacity control valve allows the dryer to operate efficiently at low loads by preventing heat exchanger freeze-ups. The control valve also keeps the dew point steady when the air flow changes. For maximum performance, it is recommended that a pre-filter be installed.

Van Air EMD Series cycling refrigerated compressed air dryers provide a consistent dew point when running at less than the design capacity. Since the actual energy cost is directly related to the amount of air dried, energy savings is maximized. For example, in a pneumatic system designed to dry 1000 SCFM, a cycling refrigerated air dryer running at 75% of the design capacity would save approximately $1,000 per year in electrical energy costs versus a non-cycling dryer. At 50% of design capacity, the savings would increase to $2,000 per year.

EMD Series cycling refrigerated compressed air dryers use direct expansion cooling to prevent dew point spikes, an inherent problem for competitive models using a thermal mass design. In thermal mass dryers, a refrigerant is used to cool a mass. This mass is then used to cool the compressed air. The time required to cool the mass delays cooling of the compressed air, resulting in dew point spikes up to 60° F that last 30 minutes or longer. These dew point spikes allow for extensive moisture carryover throughout the system.

In contrast, the Van Air cycling refrigerated dryer maintains a constant dew point temperature which helps eliminate moisture carryover. The constant dew point temperature provided by our EMD Series cycling refrigerated air dryers can be achieved because of its unique flooded evaporator design. Unlike competitive thermal mass dryers, we display a digital readout of the air dew point temperature on the cycling refrigerated dryer and issue a written guarantee of dew point performance.

Standard units are available from 80 through 8,000 SCFM. Custom units are available up to 25,000 SCFM. The capacity of the EMD Series cycling refrigerated compressed air dryer is based on operating conditions of 100° F inlet air temperature, 100° F ambient temperature and 100 PSIG operating pressure. Dryers rated for higher pressures or other operating conditions are available.

While Van Air Systems provides an extensive line of compressed air dryers, filters and other dehydration equipment, there are times when our existing product lines will not fulfill your unique requirements. Therefore, we have taken great pride in engineering and manufacturing one-off solutions to meet customer requirements. With our extensive knowledge, experience, and on-site engineering and manufacturing facilities, we are able to create custom solutions for both the most simple and demanding applications.

We are recognized worldwide as a leader in the design and manufacture of custom-d esigned solutions for compressed air dehydration. Sixty-five years experience, qualified engineers, and state-of-the-art manufacturing equipment ensure that we provide only the highest quality products to our customers.
