Let’s Talk About Cooling. Yes, In January.

Well, we’re right smack dab in the middle of January, and it’s time for the annual reminder (to myself, mainly) that I surrendered my right to complain about the cold when I moved here from Florida (on purpose) some 24 years (and 2 months, 8 days, and a handful of hours) ago.  Not that I’m keeping track.  You can follow this link (and this one, and this one) to some of my former rantings on the subject.

After an admittedly mild December in Ohio, the struggle became real this week.

But, as the title implies, I AM going to talk about a need for cooling. Of course, no matter how cold it is outside, there are many, many processes in industry that can get quite hot. Here’s one of them:

A company that operates injection molding machinery had a big problem: their machines’ molds were cooled by chilled water, and as they aged, they developed leaks, allowing water into the mold cavities. This, of course, ruined the product. To make things worse, the passages that the chilled water flows through are cast right into the machine body, so permanent repair essentially means that these bodies (the main part of the machinery) have to be replaced, at significant cost.

Last summer, they went looking for alternate methods of cooling, and found our Vortex Tubes. After some experimentation, they determined that (8) Model 3240 Vortex Tubes (2,800 Btu/hr, Maximum Cooling Power) would replicate the cooling previously provided by the chilled water systems.

EXAIR Vortex Tubes are a quick & easy method to get cold air, on demand, wherever you need it. Just like this.

They’ve since outfitted all of their injection molding machines with these, and have dodged a very expensive replacement of machinery for the foreseeable future.

If you’d like to find out how an engineered product from EXAIR’s comprehensive line can take the heat off (literally or figuratively) an application you’re struggling with, give us a call.

When the Frost is on the Pumpkin

Frost on the pumpkin

There is an interesting poem by American writer and poet, James Whitcomb Riley that paints a great picture of what fall feels and looks like on the farm. Following is just the first paragraph of his poem but it conveys his message with such elegance:

When the frost is on the punkin and the fodder’s in the shock,
And you hear the kyouck and gobble of the struttin’ turkey-cock.
And the clackin’ of the guineys, and the cluckin’ of the hens,
And the rooster’s hallylooyer as he tiptoes on the fence;

O, It’s then’s the times a feller is a-feelin’ at his best,
With the risin’ sun to greet him from a night of peaceful rest,
As he leaves the house, bareheaded, and goes out to feed the stock,
When the frost is on the punkin and the fodder’s in the shock.

In Cincinnati, they are predicting frost on the pumpkin this week. That’s a sure sign that colder temps are coming and with the colder climate returning, so does our old friend static electricity. And with static comes all the production problems that are associated with it. Static electricity will discharge to operators which makes them quite un-comfortable and can be dangerous. Discharges to sensors and computers cause malfunction. Jamming of feed mechanisms is never fun and neither is a label machine that refuses to cooperate.

So, if you are in the Northern Hemisphere like we are, get ready for the cold weather and the low humidity by placing EXAIR Static Eliminators into your processes.

The Ion Air Gun is a great all around performer for applications that require a hand manipulation to get the job done.

The Super Ion Air Knife is better for applications that need a wide area to be static free from a mountable solution.

The Ion Air Cannon is a wonderful, utility static eliminator that has great flexibility to be mounted in any position.

The Super Ion Air Wipe is a great way to eliminate static on the outside surfaces of any hose, wire or cable before ink jet printing such as date codes.

The Ionizing Point is a great way to eliminate static build up within airflows moving through duct work, conveyors and similar closed systems with air movement.

If you want your fall and winter to be as pleasant as the description in Mr. Riley’s poem, consider EXAIR Static Eliminators. You won’t be disappointed.

Winter Cold = Static Issues

Winter is fast approaching us here in Cincinnati, which can mean just about anything, temperature and weather wise. For instance, 2 years ago we had a very mild winter, with warmer than usual temperatures and very little snow. I can remember golfing in December, January and even in to February, which was awesome! But last year however was much different. We experienced a very harsh winter with extreme low temperatures (several -0°F days) and a steady amount of snowfall – I know I felt like I was shoveling the driveway and sidewalk about every 2 days! The weather was so bad that local schools ran out of snow days.

brrr
There’s no stopping winter’s cold, dry air from causing static problems – solve them with our static eliminators!

The lower temperatures mean turning up the heat on the thermostat, which is going to dry out the air. As a result of the dry air, a common problem is ESD (ElectroStatic Discharge) or static electricity. All of us at some point have probably brushed our feet on the carpet to build up a charge, then “reached out and touched someone” to give them a little jolt. While this may seem slightly humorous, the truth is, static electricity can be quite problematic.

Some common static issues:

  • Spark or shocks to personnel
  • Damage to sensitive electrical components
  • Jamming of machines
  • Particulate clinging to the surface of an object
  • Unable to separate sheets or product sticking together

EXAIR offers an extensive catalog of Static Eliminators to eliminate these common issues:

Ion Air Knives – Provides a laminar sheet of high velocity, ionized airflow. Available up to 108” single-piece lengths.

Ionizing Bars – Capable of eliminating surface static within 2” of the bar.

Super Ion Air Wipe – 360° uniform ionized airflow, ideal for ionizing extruded shapes, hose, pipe, cable etc.

Ion Air Cannon – Concentrated ionized airflow, effective up to 15 feet.

Ion Air Gun – Static eliminating, hand-held air gun, allowing easy operation.

Ion Air Jet – Static eliminating spot cleaner, available in permanent or flexible mounting.

Ionizing Point – Single point ionizer, delivering a high concentration of positive and negative ions.

We also offer our Model # 7905 Digital Static Meter, allowing you to pinpoint the source of the static. Capable of reading up to +/- 20 kV with 5% accuracy (+/-) when measured at a distance of 1”.

If you are experiencing a static issue with your process, please contact an application engineer for assistance.

An Ounce of Prevention Now = a Pound of Relief Later.

The first day of spring in 2012 is still a good 7 weeks away (March 20, 2012 at 1:14 a.m. EDT), and for those of you currently experiencing a harsh winter I apologize. Our winter in Cincinnati and the surrounding region has been one of the mildest winters ever. It has been so mild that the bulb plants have begun to emerge from the ground, which is not a good sign because with mid-Western weather we can have mid 50’s one day and below zero the next. And sure enough, Murphy’s Law being what it is, those daylilies and tulips will no sooner be fully extended out of the ground just in time for a freezing cold snap that will bring us back to reality of just what time of year it really is around here.

With all this warm weather and daffodils peeking out from the ground I begin to wonder when we will be out of the woods with the cold weather. I can’t help but plan when to get the boat out of storage and think of other warm weather activities.  As holds true for mid-Western weather, we sometimes skip the usual mild temperatures associated with “spring time” and jump right into the heat and humidity of “summer time”.

So, what’s the point of all this rambling?  It will be HOT before you know it. And last year; did you have trouble with your electric / electronic panels over-heating?  Back then, do you remember thinking to yourself that in 2012 you were going to do something about it?  I am here to tell you that NOW is the time to act to prevent yourself from having a repeat of the unfortunate events of panels over-heating and shutting down processes, causing circuit drift or frying of that $3,000.00 motor controller for which you have no back-up. If it is this warm now (excluding Denver, Colorado of course), imagine what it will be like in June, July and August this year.

I’m just saying, an ounce of prevention will be worth a pound of relief when you need it this summer. How can EXAIR help?  Well, we have just the thing. It is called Cabinet Cooler and we have a huge variety of systems which can apply to NEMA 12, 4 and 4X applications. They’re UL listed and they’re available with and without thermostat control depending on the need. Cabinet Coolers are inexpensive, low to zero maintenance, durable, simple and quick to install.
