STM’s ATEX-Certified Gearboxes adapt core series designs (A, PT, EX, RXP, etc.) for safe operation in explosive atmospheres under ATEX 2014/34/EU. These specialised units incorporate flame-proof housings, explosion-proof seals, and tested lubricants to prevent ignition of surrounding gases or dust. They maintain the performance and durability of their base series, ensuring minimal compromise on efficiency or torque capacity. Available in inline, right-angle, shaft-mount, and planetary formats, ATEX gearboxes provide comprehensive coverage for Zones 1, 2, 21, and 22 applications. Compliance is backed by full certification and traceability, simplifying risk assessments and equipment approval processes.

ATEX Gearboxes Features

ATEX versions include flame-arresting joints, stamped marking plates, and specialised gaskets to contain any internal ignition. Standard performance specifications (torque, ratio, mounting) match non-ATEX variants, ensuring drop-in replacement where hazardous-area certification is required. Approved lubricants and sealed bearings prevent contaminant ingress while maintaining gear performance. Optional features include purge gas connections for Zone 1/21 use and integrated temperature sensors for condition monitoring. All units undergo rigorous testing to ATEX and IECEx standards before dispatch, providing documented safety assurance.
