Modifying Compressed Air Blowoff for Special Applications

Modifying compressed Air Blowoff

Compressed air amplification technology can often be modified for special applications. They can be designed to clean or dry in specific ways suitable for the particular application.

Nex Flow Air Products Corp. manufacturers specialized compressed air technology for blow off, cleaning, drying, moving and cooling. Special designs can be engineered to address specific applications.

Getting a Completely Dry Surface on a Part

Some processes require absolutely dry parts and this can be attained in a fast and cost effective and efficient way. It involves optimum use of compressed air and radiant heat to minimize overall energy use and time.

What to look for in a Flat Nozzle

Some factors to consider in the use of compressed air blow off with static elimination is the strength of the charge on the part to be addressed, if you need air blow off and exposure time to the static removal system.

Nex Flow Air Products Corp has extensive experience in the use of ionized blow off systems for the cleaning statically charged parts.

When to Use a Vortex Tube Operated Cabinet or Panel Cooler System

This video outlines the conditions where vortex tube cooling units are best used for air conditioning electrical and electronic enclosures.

Vortex tube-operated Cabinet Enclosure Coolers, or Panel Coolers utilize compressed air to operate, and that energy cost needs to be offset by savings in other aspects of the application.

Four aspects should be considered: environment, space, accessibility, and overall maintenance cost.

The most humid and dirty or dusty the factory environment, the more likely a traditional air conditioning unit will be adversely affected and have a shorter life span.  Air conditioners are highly susceptible to their environment; the harsher, the shorter their life span.

If the control panel is subject to vibration, this will require increased refrigerant replacement and costly downtime.   Vortex coolers are not affected by vibration and are extremely rugged and effective in these nasty environments, with lifetimes of up to 20 years.

If space is an issue, vortex coolers are very compact and take little space compared to alternative air conditioning systems.  They are usually mounted on the top of a control cabinet but can also be mounted on the side using an optional side mount.

A functioning control panel is essential in any manufacturing operation. Vortex coolers are highly reliable and ideal for use, especially when the control enclosure is not accessible, as they have virtually no maintenance.

The dirtier and harsh the environment, the higher the maintenance of traditional air conditioning systems in both material cost and labor.  Filters on air conditioners may require weekly, if not daily, cleaning or replacement.   Even removing condensate and avoiding plugs can be an issue.

Panel Coolers create no condensate to remove.  They keep control enclosures at a positive pressure to keep panels clean, and no filters are utilized.   So there is nothing to maintain.   The more critical the control panel, the more vortex coolers are required due to their high reliability and operation security.

Implications of Being Able to Store Compressed Air

When compressed air is produced, it is first stored and then utilized from storage as it is needed. This has implications for actual energy use and cost.

Storage in a compressed air system allows users to supplement energy usage during high-demand periods, enhances air quality, and maintains system stability.

Compressed air is drawn from storage through some pressure regulation and is provided in a specific pressure range.  When the pressure in the stored tank reaches the upper level, the compressor stops.  When it drops to the lower level, the compressor turns on to build the pressure up to the upper limit.

The overall consumption of compressed air in the manufacturing facility must be less than that produced by the air compressor in the same period.

Compressed air’s implicit advantage is that the energy is stored, and waste is minimized as it can be used only when needed.     The storage capacity needs to be large enough to handle the capacity needed to prevent the pressure in the systems from dropping.

This video outlines calculating the amount of compressed air stored between the upper and lower pressure setting on the storage volume.

This can be an advantage when there are peak times when the air is needed, so you have enough to handle that demand but do not have to expend extra energy to produce the air needed.

Air quality is enhanced with storage as it allows moisture in the compressed air to condense out of the air as it cools within the storage tank and is drained off, not getting into the delivery system.

The storage tank also absorbs the pulse of the compressor going on and off when filling the tank by dampening the effect and keeping the compressed air delivery system stable.

Compressed air storage is very effective, especially in blow-off applications with on-off control.  For example, if a blow-off static requires a blast of air for five seconds and then off for five seconds and uses 50 SCFM of compressed air, the actual consumption from the storage is 25 SCFM on average.  This helps determine the actual size and availability of energy required and used.
