The role of smoke and heat exhaust ventilators

In the event of a fire, smoke and heat exhaust ventilators are designed to:

• facilitate the evacuation of hot smoke and toxic gases;

• improve visibility along escape routes;

• reduce internal temperatures, limiting the spread of fire;

• support and facilitate the intervention of rescue teams.

For this reason, the choice of an SHEV system must be based on precise technical criteria and on products that comply with current regulations.

Natural smoke and heat exhaust ventilators (ENFC)

Poliform Lucernari natural smoke and heat exhaust ventilators (ENFC) operate according to the principle of natural convection: hot air and smoke rise and are expelled through automatic roof openings.

This solution is characterized by:

• simple construction;

• long-term reliability;

• low operating and maintenance costs;

• seamless integration with skylights and monolithic domes.

ENFC systems are particularly suitable for industrial buildings, warehouses, and large covered areas.

Smoke and heat exhaust ventilators with electric or pneumatic opening

Poliform Lucernari offers exhaust ventilators equipped with electric or pneumatic opening systems, designed to ensure fast and controlled activation in emergency situations.

These solutions allow for:

• precise and immediate opening control;

• integration with fire detection systems;

• combined use for daily ventilation and fire safety.

The versatility of these systems makes them ideal for complex buildings or high-occupancy environments.

Ventilators integrated into domes and skylights

A key strength of the Poliform Lucernari range is the ability to integrate smoke and heat exhaust ventilators directly into domes, skylights, and shed roofs, maintaining both aesthetic and functional continuity.

This integration provides:

• optimized use of roof space;

• dual functionality: natural lighting and fire safety;

• reduction of critical installation points;

• improved overall system efficiency.
