UT99 AG

Based in Andelfingen, Switzerland, UT99 AG is a specialized engineering enterprise recognized for its contributions to the field of filtration technology, particularly within the maritime and power generation sectors. The company operates as a dedicated designer and manufacturer of systems intended to optimize the performance and safety of internal combustion engines. While its engineering principles apply to various industrial applications, the firm has established a significant footprint in the global shipping industry by addressing the critical challenge of crankcase emission management. The company’s primary focus lies in the treatment of blow-by gases generated by large diesel and gas engines. In the harsh environment of a marine engine room, these gases contain oil mist, which poses severe environmental and safety hazards. Uncontrolled oil aerosols can coat machinery, create slip hazards for crew members, and significantly increase the risk of engine room fires or crankcase explosions. UT99 AG addresses these issues through the development of oil mist separators that filter these hazardous particles from the gas stream. The firm’s technology is designed to coalesce oil droplets, returning valuable lubricant to the engine’s sump while ensuring that the vented air remains clean and compliant with environmental standards. Collaborating closely with Original Equipment Manufacturers (OEMs), UT99 AG integrates its solutions directly into the architecture of marine propulsion and auxiliary engines. This partnership model ensures that new vessels enter service with compliant emission control systems already in place. The company serves a diverse maritime clientele, with its engineering found on container ships, cruise liners, special purpose offshore vessels, and tankers. The operational philosophy emphasizes durability and low maintenance, acknowledging the logistical difficulties of servicing equipment while a vessel is at sea. Beyond immediate safety concerns, the company plays a role in the maritime industry's broader push toward sustainability. As international regulations regarding emissions become stricter, the efficiency of crankcase ventilation systems becomes increasingly relevant. UT99 AG supports this transition by engineering units that reduce lubricant consumption and prevent atmospheric pollution. Through a combination of Swiss precision manufacturing and a specific focus on the physics of aerosol separation, the company functions as an essential link in the supply chain for safe and clean marine power.
