Atlas Copco expands Class 2 rotary drum dryer range
Atlas Copco’s latest expansion of its rotary drum dryer range introduces new options for food manufacturers who need reliable, energy-efficient air treatment solutions that meet ISO 8573-1:2010 Class 2 air quality standards.
The MDG, iMDG, and XDG series of dryers guarantee -40°C pressure dew points with minimal energy input, ensuring compliance without the high operational costs typically associated with such strict 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 expands our offering and provides greater flexibility to meet specific operational needs.”
The heat-of-compression technology used in Atlas Copco’s MDG, iMDG, and XDG dryers regenerates the adsorptive desiccant material by using the waste heat generated by the compression process from the compressor. The compressed air used for regeneration is then pushed back in to the discharge compressed air stream, ensuring there are no losses or wastage of energy, eliminating the need for additional energy-consuming components like external heaters and blowers, or parasitic compressed air losses. This method ensures that moisture is effectively removed from the air stream while reducing energy consumption by up to 90%, resulting in a significant reduction in operational costs. This innovative approach not only ensures that compressed air meets the required -40°C pressure dew point but also reduces environmental impact, offering a more sustainable solution compared to traditional drying technologies.
Atlas Copco’s dryers are specifically designed to meet ISO 8573-1:2010 Class 2 standards, which are critical for the food production industry, where even small amounts of moisture in compressed air can lead to contamination, spoilage, and equipment damage.
The MDG 450 air-cooled dryer along with the MDG1050 and MDG 2100 water-cooled models are the newest additions to the Class 2 dryer range, offering industries even more flexibility. These dryers are designed to deliver the same guaranteed -40°C air quality, while the MDG 450 air-cooled dryer eliminates the need for a water-cooling system, ideal for environments where water is a limited resource.
The MDG 2100 water-cooled model, on the other hand, caters to industries requiring larger flow capacities while maintaining energy efficiency.
Atlas Copco’s heat-of-compression dryers offer significant energy savings over traditional systems that rely on external heaters and blowers. Unlike conventional dryers, which are often paired with oil-injected compressors, Atlas Copco’s MDG, iMDG, and XDG series can be used with oil-free compressors, providing businesses with improved air quality and even lower operational costs.
