Natural Ventilation, The Best Choice For Your Warehouse

July 16, 2012 · Posted in Family 

Natural ventilation can frequently be disregarded because it’s not easy to ‘see’ in action. However, this kind of aeration is perfect for warehouses as it is extremely effective, economic and can be designed to meet BCA specifications for natural ventilation and fire risk management.

Compared to automated ventilation (that would only function when it is on), natural ventilation works endlessly to enable the movement of renewed air all around the building. And when talking about reliability, natural ventilation wins.

Warehouses that don’t utilise natural ventilation tend to use mechanical ventilation instead. However, this creates an ongoing expense for three major reasons:

1) Lifecycle: power-driven ventilation systems have a limited lifespan, as it runs on engines that would need maintenance and may eventually stop working.

2) Servicing – because of its moving parts, this type of ventilation requires more frequent (and costly) service and maintenance than natural ventilation.

3) Power consumption: automated ventilation runs on electricity, it’s therefore a continuous expenditure.

Which kind of natural ventilation is best for your warehouse?

Ridge vents are the best type of natural ventilation for warehouses, but it’s important to remember that not all ridge ventilators are created equal.

CSIRO tested ridge ventilators are built on the science of updraft air flow that:

- Guarantees optimum performance in all weather conditions,

- Reduces the risk of back drafting, and

- Eliminates the entry of moisture.

This ‘updrafted’ design has been tested to Australian Standard AS2428, and has proven design advantages over ‘vented ridge’ designs.

How does this kind of natural ventilation for warehouses work?

Natural ventilation systems work according to the laws of thermodynamics, by providing an outlet for hot air to escape from the building. Ridge ventilators do not encompass a rotating vent – instead they updraft design encourages air to travel upwards so the air can exit out the top of the ventilator.

Our ridge vents have wind jump diaphragms at nominated points in the ventilator. These diaphragms create air pressure edges when the wind is blowing across the ventilator as well as along the ventilator guaranteeing high performance regardless of wind direction. IVR Group ridge vents also contain a unique internal guide vane system that helps shape the air through the ventilator, resulting in large air flow performance gains.

At our company, we design, engineer and manufacture all our natural ventilation products – which allows us to make them to any specification. To talk to us about ridge ventilation for your construction, contact us today or click here to visit our website.
