Product Introduction

The Legacy of Reliability: The SEB Series

The SEB Series is a time-tested pillar of Oleo’s elevator safety portfolio. With over 20 years of successful global installations, this range has protected passengers in diverse environments across the world. By utilising advanced gas-spring technology, the SEB provides a premium, robust safety solution for slow-to-medium speed elevators, combining decades of field-proven endurance with modern engineering precision.

Why the SEB Series Remains a Global Trusted Choice:

Proven Endurance: With a mass range of 450 kg to 4,545 kg, the SEB has a 20-year track record of performance. It is the “tried and tested” solution for consultants and contractors who prioritise long-term reliability.
Compact Gas-Spring Performance: Engineered to provide a sophisticated, controlled deceleration, the SEB offers the premium safety characteristics of a gas-spring system in a design that remains highly efficient and durable.
Logistics & Installation Efficiency: Designed to simplify your project, SEB units can be shipped in a compressed state to reduce transportation costs. Furthermore, they can be supplied pre-filled with oil, eliminating on-site errors and ensuring a fast, seamless commissioning process.
Universal Approval: Manufactured to Oleo’s rigorous “Zero-Failure” standards, the SEB range is universally approved and globally certified, making it a “plug-and-play” safety solution for international projects.

The SEB Series: Two decades of global success, protecting the world’s mobility one floor at a time.
