Industrial Air Conditioners and Ventilating Systems

When you talk about ventilating rooms and industrial air conditioners, the first thing that comes to mind is to open some windows and let the fresh air in. Sometimes you think about turning the fans on. If you have one, then turning on the air conditioning system is always a thought.

When you get right down to industrial ventilation, then you will see that much larger systems are required for proper ventilation.

The reason for this is because in addition to maintaining fresh air in the room, it is crucial that any airborne toxins be removed as well. This involves the safety of the employees. Several different systems are capable of performing this, yet it’s the industrial ventilation fans which are being used more often.

Our favorite cheap solution for an industrial air conditioner is the Tripp Lite SRCOOL12K Portable Cooling / Air Conditioner Stand Alone Spot Air Cooler 120V, 60Hz, 12K BTU. This is a powerful unit that will cost you less than $1000 and does an excellent job cooling.

3 Types of Ventilation Systems:

Ventilating systems come in three different types. The first is the local exhaust ventilation. It captures airborne contaminants near or right at the source, and then directs them outward.

The second system is called ‘dilution ventilation‘. This works through a process of diluting toxic air by infusing fresh air into it, and forcing the dirty air out.

The third system is called an ‘indoor quality’ type ventilating system. It brings in fresh air to be either cooled or heated. It is actually built right into an air conditioner, or a ventilating or heating system. T

he cooling systems are used more often, and for several reasons. They are the most reliable and most efficient of the ventilation methods. They are equipped with really powerful fume extraction arms, and dust extraction capabilities as well.

In order for these systems to work well, they have to be the right size for the building or room they’ll be used to ventilate. That ensures the fan will have enough suction or air pressure difference for arresting airborne toxins at their source, and directing them outward through a hood via the duct-work and exhaust mechanism.

The two options for choosing a ventilating system, are the axial fans or the centrifugal fans. The axial fans resemble propellers. They draw the air straight into the fan. The centrifugal fans look like squirrel cages. They work by drawing air into the center of the fan, then exhausting it on a 90-degree angle.

The axial systems (called ‘propeller fans’), are mainly used for dilution ventilation and cooling. You mostly find these mounted on a wall or a ceiling. When there isn’t much resistance, these propeller fans are able to circulate lots of air. However, when it comes to local exhaust ventilation, they’re not the best choice. They don’t carry enough suction to cause the air to move through the system.

The centrifugal types have good dust extraction systems. They perform well in spite of having high resistance. That’s why they are used a lot in the local exhaust type ventilation systems. There are a lot of variations on these centrifugal fans, but it’s the more rugged radial blade fans that are the cream of the crop for exhausting lots of dust. They are not easily clogged by dust.

Choosing the proper fan is something that needs to be handled by a professional. It takes someone who knows and understand industrial ventilation fans and ventilating systems to make the right selection. Having an expert make the choice, ensure that it will be a proper installation, perform well, be the right type and size, and will receive the regular maintenance checks it will require.
