The Problem
Fans Running 24/7 at Full Speed
Most car park jet fans across the UAE run at full speed 24 hours a day, regardless of how many cars are parked or what CO levels actually are. This wastes 30–50% of the energy these systems use.
Manual CO checks by security or FM teams provide a point-in-time snapshot — not continuous protection. Authority inspections require purge cycle logbooks that are often filled manually or not at all.
Our Solution
CO-Sensor-Driven VFD Control
Multi-zone CO sensors feed real-time readings into the BMS, which modulates jet fan speeds via VFDs — running at minimum speed when CO is low, ramping up proportionally as concentrations rise.
📡
Multi-Zone CO Sensors
Coverage at each parking level. Automatic threshold zone mapping.
⚡
VFD Speed Modulation
Proportional fan speed to CO level — not binary on/off.
🔥
Fire Alarm Integration
On fire signal, fans go to full purge speed automatically.
📋
Automatic Purge Logging
Timestamped purge cycle log — satisfies authority inspection without manual record-keeping.
