Customized Cooling

Published on by Brian FarnoLeave a comment

Have you ever walked through a production facility and actually looked at and in electrical cabinets? If you did, you would find very few that are identical and even ones that are similar sizes; the internals can be drastically different. When I was in the metal cutting industry customizing, installing, and servicing CNC machines, the same model machine may have different drives for an extra option and can easily add additional heat load to the panel. Bring this up because it’s time we talk about how the dimensions of a panel are not enough to select the level of cooling needed.

Some manufacturers of air movers and “traditional” enclosure cooling method devices will use merely the dimensions of a panel to estimate a heat load and then treat the panel for the worst case scenario. Sometimes it may even be a worst-case scenario for that size of panel. I’m here to tell you from experience that’s not always the best option. This is why we like to have additional information, an “inside man” on the panel, if you will. We want to know exactly what kind of air temperatures we are seeing so that we can use that information combined with some math to determine an acceptable heat load that needs to be dissipated.

The information permits us to size the Cabinet Cooler system for your exact panel; even if you have two that are the same size but one of them has some additional drives or circuits running through it, we can account for that. The reason it is essential to size each panel that has anything different in it is that all devices have some level of efficiency. So the power they consume isn’t 100% converted into their intended function. This results in some level of heat generation. That means different internal components, and different heat loads, easy as that.

This is one of the reasons we took so much care when designing and refining our Cabinet Cooler Calculator. Each variable will impact the heat load and model selection for the Cabinet Cooler System. Some major factors, such as solar heat load and cabinet color, are even accounted for when panels are located outside. We even account for existing fans that will need to be removed to seal the panel. This is because all of these factors directly affect the amount of cooling needed.

Suppose you are looking to cool down some electrical cabinets throughout your facility and want to fully understand what heat load you may need to dissipate and maintain a safe operating environment; check out our Cabinet Cooler Calculator, or contact an Application Engineer today. In that case, we can size the system while we are talking on the phone with you.

Product Overview – Gen4 Ion Air Gun

Published on by exaircorpLeave a comment

Within industrial processes, static electricity can lead to a variety of problems like printing errors, harmful shock, damaged product or shorted life for electrical components. EXAIR offers a wide range of static eliminating products that can help control this nuisance and restore material to an electrically balanced state.

When it comes to a static causing problems with a manual operation, our Gen4 Ion Air Gun is the preferred choice. The Gen4 Ion Air Gun incorporates a thumb trigger air gun with an ionizer attached to deliver a bulk of positive and negative ions to quickly eliminate the surface charge of a material, up to 5kV in only 0.18 seconds, when operated at 80 PSIG.

Easy to use, effective static elimination

The Model # 8193 Gen4 Ion Air Gun is shipped from stock with a 10′ flexible armored and electromagnetic shielded cable to protect against potential damage in an industrial setting. (special length cables up to 50′ are available if needed).  The cable assembly can also be easily removed for cleaning or replacing of the stainless steel emitter point, allowing for worry free, proper operation.

Here is a short video showing how to change the emitter point:

The Gen4 Ion Air Gun is UL recognized for the US and Canada and CE compliant, meeting the product requirements for items being sold in European markets. It also meets 2 important OSHA directives relating to the safe use of compressed air. The first being OSHA Standards 29 CFR 1910.242(b), requiring that the outlet pressure of an open pipe, nozzle, air gun, etc., when used for cleaning purposes, must remain below 30 PSI when dead-ended. The second being Standard 29 CFR 1910.95(a), protecting workers from potential injury related to dangerous sound levels of 90 dBA or higher. Additionally, the Gen4 Ion Air Gun is RoHS compliant as well.

Model # 7960 and Model # 7961 Gen4 Power Supplies – 115VAC or 230VAC, fuse protection, modular cable

They are designed to be used with our Gen4 Power Supplies, Model # 7960 with 2 outlets or the Model # 7961 with 4 outlets for powering multiple ionizers. The Gen4 Power Supplies are selectable voltage, 115VAC or 230VAC, and feature a 6′ modular power cord and lighted power switch.

To discuss how the Gen4 Ion Air Gun or any of our other products can help solve your process needs, give me a call at 800-903-9247.

EXAIR Static Eliminators Surpass Passive Static Eliminators

Published on by Brian FarnoLeave a comment

The question comes up quite a bit around this time of year as to why an EXAIR Static Eliminator is better than using a passive static eliminator to eliminate the static.   To further the explanation of a passive static eliminator, it is typically called static tinsel and is found in a variety of forms. Passive eliminators are grounded wire or strap and must come in contact with the surface of a part in order to dissipate the static charge on only that surface.  This is generally found in the form of a bare wire or some type of conductive material (copper) that is strung across the path of your parts and must come into contact with the surface of your part.   A conductive material bar is shown below.

In order for this to eliminate the static on the part you must have the fabric actually contact the surface of your part.   There are several points that this can cause an issue, the first being this item drags across the surface of your product which can wear the conductive fibers down leading to the eliminators needing to be replaced.   Second, if you have a delicate, printed, or high gloss surface, you may not want anything to touch the surface and risk a blemish.   Third, these can collect dirt and debris which may become transferred to the product.   Last, complicated shapes cannot easily be met with the passive static eliminators, these are only going to work well with flat surfaces.

Active static eliminators, such as the Static Eliminators Product Line from EXAIR offers a variety of ways to actively eliminate the static on a surface without ever touching the product.   These are ideal for delicate surfaces, painted surfaces, complicated shapes, or even flat sheets.  The EXAIR line is available with or without compressed air assist which will not only utilize your compressed air efficiently while eliminating a static charge but also blow the debris or particulate off the part.   Units without compressed air operation can eliminate static charges up to 2″ away from a surface while a unit with compressed air will eliminate static up to 20′ away.

Because the units do not contact the parts there is no need for being concerned about contamination being transferred to the part, the eliminators will not wear down from dragging across a part or surface. EXAIR static eliminators are also low maintenance products.

To top it all off EXAIR will honor a 30 day guarantee to test the products in your facility.  As well as honor a 5 year built to last warranty on compressed air products and a 1 year warranty on any electrical component.

If you would like to eliminate your static problems, contact us.
