Overview
The Tecna ATEX Balancer 9521AX 952 is engineered for safe and efficient tool handling in environments where explosive gases, vapors, or dust may be present. Fully compliant with ATEX directives, this balancer provides secure operation in II 2D Ex h IIIC T85°C Db locations, making it ideal for high-risk industries including petrochemical, refining, chemical processing, and hazardous manufacturing.
With a load capacity of 20 - 30 kg and a stroke length of 2700 mm, the unit delivers stable, predictable movement that keeps tools positioned at the ideal working height. This reduces operator strain, minimizes repetitive-motion fatigue, and enhances overall productivity.
The balancer’s internal mechanism provides precise tension regulation, ensuring consistent performance across continuous operation. Its corrosion-resistant housing and sealed components are built to withstand harsh environments, airborne contaminants, and demanding duty cycles.
Designed for low maintenance and long service life, the Tecna ATEX Balancer 9521AX 952 supports reliable day-to-day use in safety-critical applications. Whether installed on production lines, assembly stations, or maintenance areas, it helps improve workflow efficiency while maintaining strict compliance requirements.
