Expand Flexibility of Cabinet Coolers with Side Mount Kits

Last week I wrote about the Thermostat Options for Smart Cooling utilizing the EXAIR Cabinet Cooler Systems.  You can see read that blog post here.  Today we will touch base on the Side Mount Kits as an option to expand the flexibility for the installation and operation.

Sometimes there isn’t room above an electrical panel to fit the Cabinet Cooler, even though it takes just 5″ to 7.25″ of space above. In these cases, the Side Mount Kit is available to handle any of the Cabinet Cooler sizes and NEMA ratings. EXAIR offers (6) models of Side Mount Kits –

  • Model 4909 – For NEMA 12 Cabinet Coolers up to 550 BTU.hr (139 Kcal/hr), Aluminum construction
  • Model 4910 – For NEMA 12 Cabinet Coolers , 650 BTU//hr (165 Kcal/hr) and higher, Aluminum construction
  • Model 4906 – For NEMA 4 and 4X Cabinet Coolers up to 550 BTU/hr (139 Kcal/hr), Type 303 Stainless Steel
  • Model 4907 – For NEMA 4 and 4X Cabinet Coolers, 650 BTU/hr (165 Kcal/hr) and higher, Type 303 Stainless Steel
  • Model 4906-316 – For NEMA 4 and 4X Cabinet Coolers up to 550 BTU/hr (139 Kcal/hr), Type 316 Stainless Steel
  • Model 4907-316 – For NEMA 4 and 4X Cabinet Coolers, 650 BTU/hr (165 Kcal/hr) and higher, Type 316 Stainless Steel

The NEMA 4 and 4X Cabinet Coolers must be mounted vertically for the unit to properly resist the ingress of liquids and maintain the integrity of the cabinet NEMA rating.

The Side Mount Kits install into a standard electrical knockout (1-1/2 NPS) for easy installation.

EXAIR Cabinet Cooler System for Electrical Enclosure Cooling

If you watched the Webinar we hosted recently (if not, Watch It here) then you know that the EXAIR Cabinet Cooler System is an intelligent solution for electrical enclosure cooling.  The use of a Thermostat Control system is a key component to a system that provides the needed cooling while keeping compressed air usage to a minimum. There are several choices available, and I will cover those for you today.

The thermostat control systems are the most effective way to operate a Cabinet Cooler. They work by activating the the cooler only when the internal temperature of the enclosure reaches a preset, critical level. Thermostat controlled cooler systems are the best option when a cabinet will experience fluctuating heat loads, caused by operational, environmental, and seasonal changes.

Cabinet Cooler Systems that are ordered from the factory with thermostat control include a solenoid valve and thermostat.  The solenoid valve is available in 110-120VAC, 50/60 Hz, 240VAC, 50/60 Hz, and 24VDC and is UL Listed and CE and RoHS compliant. The thermostat is rated for 24V-240V AC or DC, 50/60 Hz and is UL Recognized and CSA Certified.

Solenoid Valves – 24 VDC, 110 VAC, and 240 VAC Available

 

The thermostat is factory set at 95°F (35°C). It will typically hold an internal cabinet temperature to +/- 2°F (1°C). The thermostat can be adjusted up or down if a different internal temperature is desired by turning the slotted temperature adjusting sleeve, with a 1/16 turn being approximately a 5°F change.

The solenoid and thermostat components are rated to match and maintain the Cabinet Cooler System and cabinet NEMA rating, and can be NEMA 12, NEMA 4 or NEMA 4X. A Thermostat Control can be added to an existing Continuous Operation Cabinet Cooler System, please consult the factory for help in selecting the right kit.

Step by Step Guide – Choosing Atomizing Spray Nozzles

EB1040SS

Atomizing spray nozzles atomize fluids to create a fine spray in a variety of patterns for a variety of uses. They are commonly used to mark products, paint or coat, cool, reduce dust, lubricate and clean parts.

With the numerous types of Atomizing Nozzles sold by EXAIR, it can be challenging to shift through all the information. We can help you to narrow down the field to quickly find the correct Atomizing Nozzle for your application.  In a summary, here are the basic questions that need to be answered:

1.) Are you using a pressurized liquid feed?

2.) What is the viscosity of the fluid?

3.) What is the liquid feed rate in gallons per hour (gph) or liters per hour (lph).

4.)  Should I use the No-Drip option?

EXAIR’s flow chart with easy-to-follow steps will walk you through the decision tree and land you at the best Atomizing Spray Nozzle for your application. In answering these simple questions, this chart will guide you to the correct page in our current catalog to get additional information and specifications.    Click on Link below to determine the best nozzle for you.

Video Blog: Air Entrainment Of An Air Amplifier

The following is a short video explaining how EXAIR’s Super Air Amplifiers work. It also shows the high volume of surrounding air that is pulled into the outlet flow with a very small amount of compressed air required. As yo will see, this high volume of ambient air produces a dramatic effect on the Air Amplifier’s  outlet flow. Super Air Amplifiers are very efficient, quiet and safe and can be used to vent fumes, circulate air, cool, clean and blow off surfaces.

Air Knives – What Are They Good For?

It is rare that a week goes by without a unique application of an EXAIR product…

This week I was speaking with a DJ who wished to use an air knife to create a blast of air that would add emphasis to the musical experience had by his fans. He wanted a small burst of air that would last less than a second, but would add an additional element to an already very complicated setup. My initial reaction was that no DJ I have ever seen would possibly be able to supply an air compressor big enough to feed the air knives, but over the course of our conversation, I found out that the DJ travels with 2 semi trucks of equipment, so he had some space.

Another topic that came up in our conversation was how air knives were generally used. I have been asked this in a number of ways: What are they designed to do? Where do they work best? or What are they for?

I never have a succinct answer… The air knives create a flat laminar sheet of air in various sizes from 3″ up to 108″. This laminar sheet of air can be used to move, open, float, or separate. It can be used to clean, dry, or cool. I try to categorize these applications as best I can when speaking to customers, but then you talk to a DJ, and he wants an air knife to make a crowd cheer. I never thought that would be an application for an air knife. Knowing this, how do you convey all the air knife can do in a succinct answer?

Well, I can’t, so please be patient when you ask me the same question and I run through applications from cleaning surfaces to entertaining DJ crowds.

Here is a rundown of air knife applications. In case you don’t believe me.

Move: Air Knives are used around to world to move product from a conveyor to another location.

Open: Air Knives uniform air flow is perfect for opening bags or other packaging on a packaging machine.

Float: If you need to bridge a gap between two conveyors, the air knife has done this for products from pizza dough to sheets of veneer.

Clean: Blowing products off after removing them from a CNC machine is an easy air knife application.

Dry: One of my tastiest applications was to use an air knife to blow water from a potato chip after washing, but before frying.

Cool: Extrusion, molds, and baked goods have all been cooled with an air knife.

Just because it isn’t on this list though, doesn’t mean it is not possible.  This is why we will stand behind our stock product with our 30 day guarantee.   So if you want to try an EXAIR Air Knife in your application, give us a call.

How To Choose An Air Knife

The EXAIR Super Air Knife has a prominent place near the front of our catalog, and THIRTEEN pages of photos, application details, performance data & specifications. It’s the most efficient and quietest product of its kind on the market, and our most diverse product offering in terms of size range, operational adjustability, materials of construction, and accessories available. For almost any general industrial air blow off application, the EXAIR Super Air Knife is the superior choice in terms of air usage, sound level, and capability.

EXAIR Super Air Knives come in a wide range of lengths, for a wide range of possibilities.

As tireless champions of the causes of reducing air consumption and noise, we’re always going to promote these benefits of the Super Air Knife. Still, a caller asked me the other day, “Well, why do you still make the others?”…meaning, of course, our Standard and Full Flow Air Knives. Why, indeed:

*Given the same air supply pressure, the Standard Air Knife generates the highest force of our three styles. The amount of force applied isn’t always a prime consideration…if you think about one of the more “textbook” applications for an Air Knife, it doesn’t take a great amount of force to blow off dust and light debris from a conveyor belt…certainly this is a case where efficiency factors in: the lower air consumption of a Super Air Knife can pay for the cost difference between it and a Standard Air Knife in as little as three months of operation.

The Standard Air Knife has the highest force, for when it's needed.

Of course, if you’re blowing stubborn debris out of tight spaces, like gummy, greasy dirt that’s accumulating in the recesses of a finned tube heat exchanger, that extra force can make all the difference. No; the Standard Air Knife isn’t as efficient or quiet as the Super Air Knife, but it’s still a far cry better than a drilled pipe.

*While the Super Air Knife is pretty compact – you only need a few square inches of profile area to successfully mount it – the Full Flow Air Knife is even smaller, requiring not much more than one square inch of profile for mounting. With ports on the rear face (instead of the ends & bottom for the Super Air Knife,) they can fit in very tight quarters.

Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.
Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.

The Full Flow Air Knife is also the lightest weight for a given length. A 36” Aluminum Super Air Knife, for instance, weighs about 8lbs. The 36” Aluminum Full Flow Air Knife weighs less than 4lbs. Most of the time, 8lbs is a very manageable amount of mass to support, but there are situations where every ounce matters, and if yours is one of them, you’re looking at the Full Flow Air Knife all the way.

*The biggest (in the most literal sense) factor in Air Knife selection is, well…size. We make the Standard Air Knives in lengths to 48”, and the Full Flow Air Knives come as long as 36”. The Super Air Knives, however, are stocked in lengths from 3” to 108”, and can be coupled together for as long of an uninterrupted, steady, laminar air flow as you need.

At the end of the day, a majority of blow off applications can be handled just fine with any of our Air Knives. If you’d like to discuss your application and see which one is best for you, give us a call.
