Certified smoke control architecture

Natural roof opening vents

Utilizing thermal buoyancy and aerodynamic louvers to extract high-temperature gas reservoirs without fan power, maintaining the mandatory 2.5-meter clear escape layer.

Powered mechanical exhaust

High-temperature powered extraction fans engineered for basements, multi-level concourses, and complex corridors requiring active CFM volumetric displacement.

Differential pressure systems

Variable speed pressurization units maintaining positive airflow across escape stairwells, preventing smoke infiltration through open doors during active evacuation.

Control centers and active barriers

Drop-tested automatic smoke curtains

Flexible fire-rated fiberglass aprons deployed automatically by gravity fall to form smoke reservoirs in open commercial atriums and concourses.

Emergency battery backup control panels

Microprocessor-driven central control panels with 72-hour battery standby, monitoring thermal sensors, break-glass stations, and EN 12101 pneumatic triggers.

Verified airflow calculation for every square meter of escape route

Life-safety hardware is only as reliable as the engineering parameters behind it. SHEVS calculates every volumetric velocity and thermal rise vector for full EN 12101 compliance.

Our life-safety engineering desk assists with EN 12101 calculations and CAD drawing packages.
