Smoke extraction & air quality

Smoke extraction managed, pollution monitored.
A car park built to withstand.

In the event of a fire, Hesion Eole provides smoke extraction in accordance with PS2006 regulations — the No.1 requirement for any enclosed car park. Day to day, Hesion Sense measures pollution levels (CO, NO₂) zone by zone. Together, they protect your users, ensure compliance and keep costs under control.

The Hesion partnership

Smoke extraction and pollution under control: a single decision-making chain

Hesion Eole provides PS2006-compliant smoke extraction and ventilation; Hesion Sense measures the pollution levels that inform every command. Two proprietary solutions designed from the outset to work together.

Smoke extraction · Ventilation

Hesion Eole

PS2006-compliant smoke extraction and ventilation

  • Controls smoke extraction fans in accordance with current PS2006 regulations
  • Prioritised commands: in an emergency, smoke extraction takes precedence over everything else
  • Airflows calculated to remove gases and smoke, tailored to your car park
  • A true central hub: analyses data in real time and issues commands to fans
  • Thresholds, command priorities, remote control panels, event history
  • Limits peak energy consumption — hardware and software updates included
Pollution control

Hesion Sense

Gas detection and pollution control for underground car parks

  • Multi-zone (1 to 11 zones), multi-channel (1 to 8 per zone) and multi-gas (1 to 2 per zone) control unit
  • Three detector families: CO, NO₂ and flammable LPG gases
  • Detectors installed along traffic lanes, at the appropriate height for each gas's density
  • Concentrations displayed by channel and gas on the detection control unit dashboard
  • Sends ventilation commands to control devices (Eolparc) based on detected levels
  • Monitoring, reporting tools, shared Hesion ecosystem
PS2006 smoke extraction

Smoke extraction: your car park's No.1 requirement

In the event of a fire, comfort ventilation immediately gives way to smoke extraction. Hesion Eole controls extraction fans in accordance with current PS2006 regulations — a mandatory, priority system for user safety — and places the fans at the disposal of firefighters, who can take control in any circumstances.

  • Prioritised commands: firefighter control takes precedence over all others
  • Fans are placed at the disposal of firefighters in all circumstances
  • Smoke extraction airflow calculated to suit your car park's characteristics
  • Verifiable PS2006 compliance: event history, reporting
  • Remote control panels for operators and emergency services

How it works

From molecule to fan, in real time

Detectors measure

Along traffic lanes, CO, NO₂ and LPG detectors continuously measure gas levels — up to 11 zones and 8 channels per zone.

The network diagnoses

Networked operation ensures reliable diagnostics and accurate information, relayed to the supervisory system.

Hesion Eole decides

The Hesion Sense gas detection controller transmits ventilation commands: the Hesion Eole concentrator analyses them and controls the fans — sequenced starts, adjusted speeds and command priorities respected.

Fans adapt

Airflows adjusted to actual gas and smoke extraction needs. In an emergency, PS2006 smoke extraction takes over.

Use cases, made simple

From compliant smoke extraction to energy savings

Four real-world situations, four measurable benefits.

Smoke extraction

Smoke extraction, a vital requirement

In the event of a fire, smoke must be extracted in the right place and at the right rate — PS2006 regulations require it, and your users' safety depends on it.

See the solution

Solution: Hesion Eole controls smoke extraction fans in accordance with current PS2006 regulations: prioritised commands, airflow rates calculated for your car park, remote control panels and a complete event history. Benefit: protected users, verifiable compliance during inspections, and continuously monitored equipment.

Crisis management

An emergency declared? The response is immediate

Smoke detected: comfort ventilation must give way to safety smoke extraction, with no misdirected commands and not a second lost.

See the solution

Solution: Hesion Eole automatically switches to smoke extraction mode: predefined command priorities, absolute priority for smoke extraction, and events logged in real time. Benefit: a coordinated response within seconds, fully traceable for post-incident analysis and insurance purposes.

Energy

Smarter ventilation, lower energy use

Ventilation runs at full power day and night while the car park is almost empty: electricity bills soar.

See the solution

Solution: Hesion Sense activates ventilation only when truly needed, and at low speed, by analysing detector readings collectively. Benefit: significantly lower electricity bills, and a ventilation profile tailored to your car park, with an « energy-saving » mode featuring an adjustable power limit.

Durability

Long-lasting equipment, controlled costs

Extensive cabling, corrective maintenance, unexpected operating costs: deployment can quickly put pressure on your budget.

See the solution

Solution: Hesion Sense and Hesion Eole run on a single communication bus, with less hardware and less labour — connected supervision included. Benefit: savings from deployment onwards, preventive rather than corrective maintenance, and longer-lasting motors.

Operations

Automated, traceable operations

Manual readings, late alerts, reports that are difficult to produce for regulatory inspections.

See the solution

Solution: all measurements and commands are relayed to a central supervisory system: event history, reporting tools, remote control panels, and hardware and software updates included. Benefit: automated operations, longer-lasting motors, and inspection-ready reports.

Compliance & benefits

Compliant yesterday, adaptable tomorrow

Ventilation and smoke extraction motor control must first meet regulatory requirements. Hesion solutions go further: reprogrammable as standards evolve, they support your car parks for the long term.

Regulatory compliance

PS2006 and harmful gas monitoring: compliant, auditable and traceable car parks.

Energy efficiency

Ventilation runs only when needed — no more consumption peaks.

Motor lifespan

Sequenced starts and adjusted speeds: your fans last longer.

Risk prevention

Early CO/NO₂ detection, alerts and supervision: stay ahead of operational risks, rather than reacting to them.

The Hesion ecosystem
