CO Car Park Ventilation System: Smart Carbon Monoxide Detection & Automatic Fan Control

Carbon Monoxide (CO) detection and automatic ventilation are essential for maintaining a safer environment in enclosed and basement parking areas. Vehicle exhaust can cause CO levels to increase, particularly in enclosed car parks where natural ventilation is limited. A properly designed CO-based ventilation system can continuously monitor CO concentration and automatically operate exhaust fans according to programmed set points.

Complete Solution from Detection to Automation

At ALVI Automation India Pvt. Ltd. – GasAlarm, we provide integrated solutions combining MSR Electronic, Germany CO Gas Detection technology with PLC/HMI-based control and electrical starter panels for automated car park ventilation systems.

How Does a CO Car Park Ventilation System Work?

The system works as a continuous monitoring and automatic control loop:

MSR CO Detector → ALVI PLC/HMI Panel → Starter/VFD Panel → Exhaust Fans → Ventilation

1. CO Detection

MSR-GasAlarm CO sensor transmitters are installed at appropriate locations throughout the basement parking area on coloum heeight 1.5m-1.8m.

The detectors continuously monitor the CO concentration and transmit the measured signal to the control panel through the configured communication/output interface.

Depending on the system design, multiple detectors can be connected to a central monitoring and control system.

2. PLC & HMI Control Panel

The ALVI PLC Control Panel with HMI receives the detector signals and displays the status of individual sensors.

The HMI can provide information such as:

• AI – Sensor-wise CO concentration
• Alarm status
• First/second alarm indication
• Fan operating status
• Auto/Manual operation
• Basement or zone identification
• System fault/status indication

This gives facility and maintenance teams a centralized view of the parking ventilation system.

3. Automatic Fan Control

When the measured CO concentration reaches the programmed ventilation/alarm set point, the PLC generates the required control signal.

The signal is sent to the DOL starter or VFD starter panel, which operates the ventilation fans according to the system design.

With VFD-based systems, fan speed can be controlled according to the ventilation requirement, where applicable.

4. Exhaust & Fresh-Air Ventilation

The ventilation fans extract contaminated air from the basement and discharge it through the exhaust duct system, while fresh air is introduced through the designed fresh-air arrangement.

The objective is to maintain appropriate ventilation conditions while avoiding unnecessary continuous fan operation where automatic control is designed and permitted.

A typical installation can be configured as:

CO Sensor Transmitters
↓
4–20 mA / RS485 Communication
↓
ALVI PLC + HMI Control Panel
↓
Control Signal
↓
DOL / VFD Starter Panel
↓
Exhaust & Fresh-Air Fans
↓
Basement Ventilation

The system can also be designed for BMS integration, allowing relevant alarms, sensor values and equipment status to be monitored through the building management system.

Applications

Our CO detection and ventilation control solutions can be considered for:

• Basement car parks
• Shopping malls
• Hotels
• Hospitals
• Commercial buildings
• Residential towers
• Airports
• Office buildings
• Multiplexes
• Multi-level parking facilities

Continuous monitoring of Hydrogen, Oxygen, Temperature, and Humidity in UPS battery rooms

⚡ Why Hydrogen, Oxygen & TRH Monitoring is Critical in UPS Battery Rooms ⚡

Continuous monitoring of Hydrogen, Oxygen, Temperature, and Humidity in UPS battery rooms is not just a safety measure—it is an operational necessity.

Excess hydrogen accumulation can go unnoticed until it reaches explosive limits, while abnormal oxygen levels significantly increase fire and personnel risk. Temperature and humidity fluctuations accelerate battery degradation, reduce backup time, and lead to premature battery failure.

An integrated detection and control system enables real-time visibility, early fault identification, and automatic corrective action through ventilation and alarms. This proactive approach minimizes maintenance costs, improves system reliability, and ensures uninterrupted power availability for mission-critical data centre operations.

UPS battery rooms are the backbone of data centres — but they also pose hidden safety risks if not continuously monitored.

🔍 Key Risks in UPS Battery Rooms
🔹 Hydrogen (H₂) Gas – Released during battery charging; highly explosive at low concentrations
🔹 Oxygen (O₂) Levels – Oxygen depletion or enrichment can create serious fire & safety hazards
🔹 Temperature & Humidity (TRH) – Directly impacts battery life, performance, and failure rates

🛡️ Smart Detection = Proactive Safety
Our integrated detection system continuously monitors:
✔ Hydrogen & Oxygen gas concentration
✔ Temperature & Humidity conditions
✔ Generates instant audible/visual alarms
✔ Automatically triggers exhaust ventilation via control panel

📊 Benefits for Data Centres & UPS Rooms
✅ Prevent explosion & fire hazards
✅ Ensure battery health & longer life
✅ Maintain compliance with safety standards
✅ Avoid unplanned downtime & equipment damage

🚀 Safety is not optional — it’s engineered.
Early detection and automated response protect people, infrastructure, and uptime.

DE16 Differential Pressure Transmitter

Application Fischer Germany DE16 Differential Pressure Transmitter :

Fischer Mess- und Regeltechnik GmbH, Germany DE16 Differential Pressure Transmitter Measuring transmitter for overpressure, partial vacuum, and differential pressure. This series is suitable for various measuring applications in the field of industrial and sanitary techniques.

Typical applications:

• Measurement of differential pressure between forward- and returnflow in heating systems.
• Monitoring of filters, blowers, and compressors.

Main Features:

• Overpressure protection
• Rugged design
• Maintenance and wear-free inductive pick-up
• Multiple applications.

Construction and Operation :

This transmitter is based on a rugged and uncomplicated diaphragm movement, suitable for overpressure, partial vacuum and differential pressure measurement.

The operating principle of the system is identical in all three applications. In a state of equilibrium, the forces of the springs on both sides of the diaphragm are balanced.

The pressure or differential pressure to be measured creates an unbalanced force of the springs for the measuring range until a new equilibrium is reached.
A centre-mounted tappet transfers the motion of the diaphragm system to the core of an inductive displacement transducer.

The subsequent converter circuit transfers this motion into an electrical output signal. The transmitter is short-circuit and reverse battery protected.

Ethylene Monitoring in Ripening Chamber

Fruit ripening chambers require controlled ethylene concentration (50–150 ppm) along with precise temperature (14–20°C) and relative humidity (85–95% RH) to ensure uniform, safe, and high-quality ripening.

Ethylene Gas Sensor for Fruit Ripening Chambers

The MSR Electronic Ethylene Gas Sensor is engineered for accurate monitoring and control of ethylene concentration inside controlled atmosphere and fruit ripening chambers.

Ethylene plays a critical role in initiating and regulating the fruit ripening process. Uncontrolled levels can lead to uneven ripening, spoilage, or safety risks. This sensor ensures precise ppm-level detection, enabling optimized ripening cycles and consistent fruit quality.

Key Features

• Continuous ethylene gas monitoring (ppm range)
• Robust industrial enclosure suitable for humid environments
• Compatible with PLC, BMS & automation systems
• Long-term stability and low maintenance
• Ideal for safety alarms and ventilation control

👉 Why TRH is Important

Even with correct ethylene dosing, improper temperature or humidity can ruin the batch:

• Too hot → uneven ripening, spoilage
• Low humidity → fruit dehydration & weight loss
• High humidity → fungal growth

Typical Applications

• Banana ripening chambers
• Mango & papaya ripening rooms
• Cold storage facilities
• Food processing & agri-infrastructure projects
• System Integration

The sensor can be seamlessly integrated with:

• PLC-based control panels
• Temperature & humidity (TRH) sensors
• Exhaust and circulation fan control
• Alarm and safety interlock systems

Resulting in uniform ripening, reduced losses, and compliance with food safety standards.
