ASCO

What ASCO does

ASCO (ASCO Kohlensäure AG) is a Swiss industrial technology company founded in 1975 and headquartered in Wittenbach, Switzerland, that specializes in CO2 recovery systems and dry ice production and handling equipment. Since 2007, it has operated as a wholly owned subsidiary of the Messer Group, functioning as the group's global competence center for CO2 technologies, with regional offices in Germany (Bad Hönningen) and the USA (Orange Park, Florida) and a customer base spanning more than 160 countries. ASCO serves heavy-industrial customers in cement, steel and metals, oil & refining, power generation, biogas, food & beverage, desalination, and adjacent verticals.

The company's core technology is the proprietary ASCOSORB-RS absorbent, used in modular, fully automatic CO2 recovery plants (SGR for flue gas, BPR for by-product, and RRSI for recovery from dry ice production) that deliver 99.9%+ purity suitable for food-grade applications. On the dry-ice side, ASCO offers the EVO-Series pelletizers (P55, P75i, R70i, BP420i, BP425i), ASCOJET dry-ice blasting machines, packaging and storage systems, and the Active Dry Ice Saw (AAS). In partnership with Landmark Power Holdings and Rolls-Royce Power Systems, ASCO co-developed the FLEXPOWER PLUS modular concept integrating CO2 capture with mtu gas engines, demonstrated at a 10 MW commercial plant in Worksop, UK.

ASCO's revenue model is anchored in capital-equipment sales (CO2 recovery plants, dry ice machines, ASCOJET blasters, storage tanks, dosing and cylinder-filling systems), supplemented by a Carefree rental offering, a global service and remote-maintenance network, and direct dry-ice sales. Distribution is predominantly direct enterprise field sales, supported by website-driven inbound inquiries and the regional offices; pricing is custom-quoted, reflecting the engineered-to-order nature of the equipment.
