Atlas Copco’s latest expansion of its rotary drum dryer range introduces new options for food manufacturers seeking reliable, energy-efficient air treatment solutions that comply with ISO 8573-1:2010 Class 2 air quality standards.
The MDG, iMDG, and XDG series of dryers ensure -40°C pressure dew points with minimal energy input. This guarantees compliance without incurring the high operational costs typically associated with such stringent air quality requirements.
“Our dryers meet the demanding -40°C air quality standard with minimal energy input, allowing industries to comply with ISO 8573-1:2010 Class 2 requirements at a fraction of the cost,” said Michael Pingram, product specialist at Atlas Copco. “The addition of the MDG 450 air-cooled dryer, along with the MDG1050 and MDG2100 water-cooled models, enhances our offering and provides greater flexibility to meet specific operational needs.”
Atlas Copco’s MDG, iMDG, and XDG dryers utilize heat-of-compression technology, which regenerates the adsorptive desiccant material by harnessing waste heat from the compression process. The compressed air used for regeneration is pushed back into the discharge compressed air stream. This innovative approach eliminates energy wastage, negating the need for additional energy-consuming components such as external heaters and blowers, while also reducing parasitic compressed air losses. Consequently, moisture is effectively removed from the air stream, achieving up to 90% energy savings, and significantly lowering operational costs. Additionally, this method ensures compliance with the required -40°C pressure dew point and reduces environmental impact, making it a more sustainable solution compared to traditional drying technologies.
Designed specifically for the food manufacturing industry, Atlas Copco’s dryers comply with ISO 8573-1:2010 Class 2 standards, a critical requirement where even minimal moisture in compressed air can lead to contamination, spoilage, and equipment damage.
The MDG 450 air-cooled dryer, combined with the MDG1050 and MDG2100 water-cooled models, represents the latest additions to the Class 2 dryer range, offering food manufacturers enhanced flexibility. The MDG 450 air-cooled dryer eliminates the need for a water-cooling system, making it an ideal choice for environments where water is scarce.
In contrast, the MDG 2100 water-cooled model addresses the needs of industries requiring larger flow capacities while ensuring energy efficiency.
Atlas Copco’s heat-of-compression dryers provide significant energy savings compared to traditional systems reliant on external heaters and blowers. Unlike conventional dryers, which are often paired with oil-injected compressors, the MDG, iMDG, and XDG series can be effectively used with oil-free compressors. This offers food manufacturers improved air quality and further reduces operational costs.
