ventilation & air flow monitoring

How sure are you about your ventilation effectiveness?

Ventilation systems onboard ships supply and remove air to / from spaces throughout the ship. In this way, these systems control breathable air quality and protect personnel and sensitive equipment against potentially dangerous atmospheric pollutants, fires, explosions and excessive heat. For these reasons, airflow monitoring is important and critical, just as critical and important is the reliability and quality of the airflow sensor used for this purpose.

Some important applications of air flow ventilation monitoring in marine settings include:

Engine Room Ventilation: Engine rooms on ships and boats require proper ventilation to remove heat generated by engines and machinery. Monitoring the airflow in engine rooms ensures that ventilation systems are operating effectively, preventing the buildup of excessive heat, maintaining equipment performance, and minimizing the risk of fire or engine failure due to overheating.

Accommodation Spaces: Proper ventilation is essential in the living quarters of marine vessels to maintain a comfortable and healthy environment for crew members. Monitoring airflow in accommodation spaces helps ensure adequate air exchange, removal of odors, prevention of condensation and mold growth, and regulation of temperature and humidity levels.

Cargo Holds and Storage Areas: Monitoring ventilation airflow in cargo holds and storage areas on ships is crucial to prevent the buildup of moisture, mold, and unpleasant odors. Proper airflow helps maintain cargo integrity, reduce the risk of spoilage or damage, and create safe and suitable conditions for stored goods.

Bilge and Ballast Spaces: Monitoring airflow in bilge and ballast spaces helps prevent the accumulation of stagnant air, moisture, and foul odors. Adequate ventilation in these areas is essential to minimize the risk of corrosion, mold growth, and the presence of harmful gases or vapors.

Safety and Emergency Situations: Proper ventilation plays a critical role in marine safety, especially during emergency situations such as fires, leaks, or hazardous material spills. Monitoring airflow helps ensure that ventilation systems can effectively remove smoke, fumes, or toxic gases from affected areas, improving the chances of safe evacuation and facilitating firefighting and rescue operations.

Environmental Compliance: Monitoring ventilation airflow in marine vessels is important for compliance with environmental regulations. Properly functioning ventilation systems help minimize the release of pollutants, exhaust gases, or harmful emissions into the environment, contributing to sustainable and responsible marine operations.

Energy Efficiency: Monitoring air flow ventilation in marine environments contributes to energy efficiency. Optimizing airflow rates, balancing ventilation systems, and identifying areas with excessive energy consumption can help reduce fuel consumption, lower operating costs, and minimize environmental impact.

In summary, monitoring air flow ventilation in marine environments ensures the safety and well-being of crew members, protects cargo, promotes environmental compliance, and contributes to energy efficiency in various areas of a marine vessel.

Models 0101, 5101, 5201

This compact air flow sensor is specially designed for air flow monitoring and protect against the loss of airflow where it is necessary to recognize the loss or reduction of airflow providing early warnings. Its compact housing style fits easily into ventilation systems and features an adjustable potentiometer to establish a setpoint. A LED provides visual indication when flow is above or below the setpoint. This airflow sensor is based on the calorimetric principle and is an inexpensive alternative for mechanical flaps and pressure cells. All components of the airflow sensor are incorporated in a compact smooth cylindrical plastic housing. The airflow sensor has a built-in timer that serves as a switch-on delay for the fan or ventilator. During this time the output is closed, the relay is energized which is also visually displayed by means of a simultaneous lighting of a red and a green LED. The switch point can be set by means of a potentiometer and is indicated by a red or green LED. In the case of no flow the red LED lights. If the green LED does not light, the output relay is de-energized. When the airflow monitor detects flow the red LED goes out, the green one lights and the output relay is energized. The output signal is available as a floating NO contact. The length of the airflow monitor allows a maximum immersion of 120 mm into the air duct. It is installed by means of a mounting clamp which is secured to the duct via two self-tapping screws. The airflow sensor can also be used for industrial airflow monitoring, since during the design of the sensor part special emphasis was put on the protection of the PTC`s against mechanical destruction by solid particles in the medium. The PTC`s are included in the sensor head and are protected against mechanical damage from outside by means of flush mounted metal plates. The metal plates also provide a good heat contact to the medium.
