Enjoy this Summer by Avoiding Heat Related Electrical Problems with Cabinet Cooler® Systems

For many of us, summer contains some of the most enjoyable months coming up in North America. Summer typically brings more time spent outside, basking in the sunshine, lemonade, iced tea, grilling, gardening, fishing, hiking etc.

These enjoyable hot summer months coming upon us can also bring some elevated temperatures within electric control panels – but we have a simple and effective solution to avoid any heat related shutdowns and interference with electrical systems.  EXAIR can eliminate these with our Cabinet Cooler Systems, you just get on with the grilling and basking in the sun.

With freon based coolers, higher ambient conditions make them less effective; and opening the electrical panel to have a fan blow inside creates a dangerous electrical hazard.  For every 10 oC rise above the operational temperature, the life of an electrical component is cut in half.  To reduce loss in production and premature equipment failures, it is important to keep your electrical mechanisms cool.  The EXAIR Cabinet Coolers are designed to do just that.

How the EXAIR Cabinet Cooler System Works

How does the Cabinet Cooler work? 

Cabinet Coolers are powered by an EXAIR Vortex Tube which only uses compressed air to generate cold air.  They do not have any moving parts, Freon to leak, or refrigerant compressors to fail.  These simple, but effective, cooling devices can be used in the toughest of environments.  With the Vortex Tube as the “engine”, the reliability of the EXAIR Cabinet Cooler is unmatched and makes it an easy choice for cooling electrical panels.

What NEMA ratings does EXAIR offer? 

To match the same integrity as your electrical panels, EXAIR offers three different types of NEMA ratings that are UL listed and CE compliant.  NEMA 12 is dust and oil tight, and can be related to the IEC standard, IP54.  NEMA 4 is dust and oil tight as well as splash resistant for indoor and outdoor use.  The NEMA 4X is the same as the NEMA 4 except it is made of stainless steel for corrosive areas and aggressive wash-down environments.  Both the NEMA 4 and 4x corresponds to an IP66 rating.  EXAIR Cabinet Coolers are easily installed and can match your electrical panel to keep the electrical components safe inside.

What size Cabinet Cooler do I need? 

EXAIR makes it easy to get the proper cooling with the Cabinet Cooler Sizing Guide.  This guide goes over the important information to determine the external and internal heat loads.  It also indicates the proper NEMA type and electrical requirements for easy installation. The cooling power ranges from 275 BTU/hr to 5,600 BTU/hr, and with the filled-out form, we can make sure that the correct model is used.

Thermostat- Controlled System

What types of systems are offered? 

EXAIR offers a continuous operating system and a thermostat-controlled system.  The continuous operating system includes the selected Cabinet Cooler, a filter, and a cold air distribution kit.  The system will continuously cool until it is manually or automatically turned off.

The thermostat-controlled system is the most efficient way to operate a Cabinet Cooler.  This system comes with the selected Cabinet Cooler, filter, cold air distribution kit, a thermostat and an electrical solenoid valve.  The system is designed to operate only when cooling is needed.  The thermostat controls a solenoid valve, and it is preset at 95°F (35°C).  The thermostat can be easily adjusted to match other desired temperatures.  The solenoid valves come in three different voltages, 120Vac, 240Vac, and 24Vdc (which ever voltage is easily accessible).  With the thermostat-controlled system, you do not have worry about the system operating during off-peak conditions or cooler seasons.

What other options does EXAIR offer with the Cabinet Cooler Systems? 

For better temperature control, EXAIR can replace the standard thermostat and solenoid valve with the ETC, or Electronic Temperature Control.  It is a digital temperature controller with a LED screen for precision monitoring and adjusting.  The controller has easy-to-use buttons to raise or lower the desired internal cabinet temperature.  Once set, the ETC will hold the temperature to +/- 1 oF (+/- 0.5 oC).  The LED displays the internal temperature for continuous monitoring.  The ETC comes complete with the controller and a solenoid valve in two different voltages, 120Vac and 240Vac.  The ETC is a great option for real-time accurate measurements for your panel cooling.

Another option that EXAIR offers is the Side Mount Kit.  They are used to mount the Cabinet Coolers on the side of the electrical panel.  They are manufactured to match the NEMA rating of the Cabinet Cooler.  If you have limited space, don’t worry.  The Side Mount Kits gives you more areas to mount the Cabinet Cooler to your electrical panel.

What about harsh environments? 

  • With elevated ambient temperatures like near ovens, the high temperature version would be your option. The HT Cabinet Coolers work in temperatures from 125 oF to 200 oF (52 oC to 93 oC respectively).  With refrigerant coolers, the elevated temperatures make it very difficult to cool effectively.  But with the EXAIR HT Cabinet Coolers, the high temperature will not affect the ability to blow cool air.
  • If the environment is extremely dirty with lint, fibers, debris, etc., EXAIR offers an NHP, or Non-Hazardous Purge, version. The solenoid valve is designed to allow 1 SCFM of compressed air into the panel to keep a slight positive pressure. With the NHP Cabinet Coolers, the ingress of any fine particles into your electrical panels are eliminated.
  • For food and beverage, pharmaceutical, and corrosive type of applications, EXAIR can offer NEMA 4X Cabinet Coolers made from 316SS material. With the high corrosion resistance, the 316SS Cabinet Coolers will continue to operate without degrading in tough environments.
  • In Class I, Class II, and Class III hazardous areas, EXAIR has the HazLoc Cabinet Coolers. They are UL classified and can work with X-type and Z-type purge systems for the thermostat-controlled system.  The solenoid valves are also designed to be located in these areas with the same three different voltages.  The Hazloc Cabinet Coolers can be sold as a continuous operating system as well.

Cold Gun Aircoolant System™: Overview

EXAIR Cold Gun Promotion

Many machining companies like to use coolant to flood their parts for drilling and milling operations.  But what if there was an alternative way?  EXAIR has an interesting technique by using cold air instead of coolant.  This would help save time by eliminating cleaning and drying of parts as well as reducing coolant waste.  EXAIR calls this product our Cold Gun Aircoolant System™.

How the Cold Gun Works

The Cold Gun Aircoolant System uses a Vortex Tube to produce a cold air stream at 50oF (28oC) below supply air temperature.  Heat is one of the major causes for dulling and premature failures for tools, and by blowing cold air, it will reduce the heat buildup in tools while also removing the chips from the surface.  The EXAIR Cold Guns are very compact, portable, and easy to use.  Just attach compressed air to the unit, and it will produce cold air.  Since they do not have any moving parts, Freon, or electricity to operate, it is maintenance-free and long-lasting.  And, EXAIR offers a 5 year “Built To Last” warranty against defects in workmanship and materials.  These systems will extend tool life, improve tolerance control, and increase production rates by replacing coolant during milling, cutting, and drilling operations.

The benefits of using the Cold Gun Aircoolant System extends beyond reducing tool wear, finishing with dry parts, and surface smearing.  It can be used in applications where liquid coolant cannot be used.  This would include wood products, MDF, and plastics.  As insulators, cutting tools will get extremely hot as the material will not remove any heat like with metal chips.  Thus, machining can soften, gall, or burn the surface of the material; allowing only slow speeds for operations.  The cold air from the Cold Gun can keep the tools sharp and the materials hard and firm.  With plastic materials, this is very beneficial as it will keep the plastic rigid for tight tolerance machining.  If burnishing or scoring is occurring, the Cold Gun Aircoolant Systems can help to improve the surface finish of your product.  Other applications would include surface grinders, laser cutters, hot melt setting, and band saws.  The Cold Gun Aircoolant Systems are a low-cost solution that can do a lot of great things to improve processes.

Cold Gun Aircoolant Systems

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.  The four models that EXAIR stocks are in the photo above.

EXAIR is running a promotional offer on the Cold Gun Aircoolant Systems.  From now until the end of yr2019; if you buy a Single Point Cold Gun System or a Single Point High Power Cold Gun System; model W5215 and model W5230 respectively, we will include a free model 5902 Dual Point Hose Kit, a $39.00 value, with your system.  And as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out.  If you have an application that you believe would be better served with an EXAIR Cold Gun Aircoolant System™, contact an Application Engineer.  And take advantage of our promotional offering by receiving a FREE Dual Point Hose Kit.

Promotional Item: Gen4 Static Eliminators and a free AC Sensor

As the weather gets colder and the air gets dryer, static electricity can become a real nuisance in a production plant.  Machines will start jamming, alignments will be difficult, debris will collect on surfaces, and hazardous sparks can shock personnel.  EXAIR manufactures a large line of Gen4 Static Eliminators to remove this static nuisance.  And beginning January 1st, 2019; EXAIR will be giving away a free AC Sensor, a $57.00 value, with a purchase of any of the Gen4 Static Eliminators.

EXAIR stocks eight different product lines in two different styles, Gen4 Static Eliminators with Air and Gen4 Static Eliminators without Air.  In conjunction with a power supply, these ionizers can create both negative ions and positive ions to remove any type of static charge that is on the surface.  The Gen4 Power Supplies come in either a 2 port or 4 port configuration; so that, you can power multiple Gen4 Static Eliminators at once.  From the power supply to the ionizer, an armored and electromagnetic shielded cable is used in a single wire design. This helps to protect the cable from abrasions, cuts and splits in industrial areas.   The Gen4 Static Eliminators have a shockless design, and are UL Component Recognized and CE compliant.  I will give a brief description of each product that utilizes this rugged industrial design for optimal static neutralization.

Gen4 Static Eliminators with Air:

Gen4 Super Ion Air Knife
  1. Gen4 Super Ion Air Knife: This product has the best compressed air efficiency in removing static by combining the Super Air Knife with an Ionizing Bar.  The Gen4 Super Ion Air Knife has a 40:1 amplification ratio and uses the laminar air flow to carry the positive and negative ions to the surface up to 20 feet (6.1 meters) away.  The laminar air flow also allows for a quick static discharge in applications with fast conveyance speeds.  EXAIR manufactures stock lengths from 3” (76mm) to 108” (2.74 meters).  Some typical applications for the Gen4 Super Ion Air Knife are found in web cleaning, sheeters, pre-paint dust removal, and shrink wrappers.

    Gen4 Standard Ion Air Knife
  2. Gen4 Standard Ion Air Knife: Similar to the Gen4 Super Ion Air Knife, the Gen4 Standard Air Knife has a good efficiency at 30:1 amplification ratio.  It utilizes the Coanda effect to draw in ambient air, and they come in stocked lengths from 3” (76mm) to 48” (1.22 meters).  The Gen4 Standard Ion Air Knife are used in similar applications as well as mold releasing, package cleaning, label applications and plastic bag opening.

    Gen4 Super Ion Air Wipe
  3. Gen4 Super Ion Air Wipe: This product blows ionized air in a 360-degree pattern.  They are engineered to remove static and debris from the outside of hoses, plastic pipes, extrusions, and coated wires.  With the split design, the Gen4 Super Ion Air Wipe can easily mount around the product without having to rethread.  They come in two different sizes with a 2” (51mm) and 4” (102mm) inner diameter. The ionized air has a fast decay in removing static for speedy transfers.

    Gen4 Ion Air Cannon
  4. Gen4 Ion Air Cannon: Just like the name, this product will shower an area with ions to remove static. It can reach distances up to 15 feet (4.6 meters).  They are used in multiple areas including pre-paint car bodies, containers, shrink packaging, lenses, etc.  As an Air Amplifier, a small amount of compressed air will draw in a large amount of ambient air.  The ions are carried to the surface by the Gen4 Ion Air Cannon in a laminar air steam.   Once the ions coat the surface area, the air flow can gently remove any debris held by static forces.

    Gen4 Ion Air Gun
  5. Gen4 Ion Air Gun: For manual static removal to target specific areas, the Gen4 Ion Air Gun will work great.  This product comes standard with 10 feet (3 meters) of shielded cable for maximum reach.  An ergonomic air gun is attached to a Gen4 Ion Air Jet to manually remove static in difficult areas and to pre-treat within “shock” zones.  The Ion Air Guns work great for small batch processes used for quality checks or label applications.

    Gen4 Ion Air Jet
  6. Gen4 Ion Air Jet: Similar to the Ion Air Gun, this product is used for “hands-free” operations. They use a small amount of compressed air to “shoot” the ions onto a target area.  They can be operated with a solenoid valve or foot pedal to blow ions during specific times and situations.  They can easily be attached to a Stay Set Hose and Magnetic Base for best “hands-free” positioning for optimal cleaning.  They work well on small targets for automated systems or inspections areas prior to packaging.

Gen4 Static Eliminators without Air:

Gen4 Ionizing Bar
  1. Gen4 Ionizing Bar: This rugged design is for industrial use to remove static cling from flat surfaces. They range in length from 3” (76mm) to 108” (2.74 meters).  Without the assistance of air, the product has to be within 2 inches (51 mm) from the surface to remove static charges.  The Gen4 Ionizing Bar is compact, shockless and works well in applications where blowing air could be a detriment.  The applications would include screen printing, labeling, and large printing processes.

    Gen4 Ionizing Point
  2. Gen4 Ionizing Point: This single point design is manufactured to remove static on small targets in tight spots.  Utilizing the same rugged design, this product can remove static in spot areas and help to stop jams from slitting operations. They can also be panel mounted to neutralize areas using ducted air.
Model 7929 EXAIR AC Sensor – FREE to end user customers when purchasing ANY EXAIR Gen4 Static Eliminator through March 31st, 2019

Now how about that free promotional item, the AC Sensor, with a purchase of any of the Gen4 Static Eliminators above?  This device, as mentioned above, has a $57.00 value which you can get for free.  This sensor provides a non-contact way to verify if voltage is present.  A red light at the tip will glow, and an audible tone is sounded when voltage is detected.  The model 7929 AC Sensor is an ideal tool to quickly verify that power is going to your ionizer.  This instrument will also work for finding power in receptacles, junction boxes, switches and breaks in power cords.  Batteries will be included, so you can start using it right after receiving the robust Gen4 Static Eliminators.
