EXAIR Cabinet Coolers, Solve Your Overheating Issues Today!

EXAIR NEMA 4X Cabinet Coolers

Industrial facilities incorporate a variety of processes and procedures to meet customer demands.  The ability to convert incoming resources into the desired output hinges upon proper up-time inside of the facility.  Whether producing raw materials, performing value-adding services, or manufacturing consumer goods, downtime and failed systems inside of an industrial facility mean lost throughput, lost profit, and increased cost.

As temperatures begin to rise across the US, heat related equipment failures become more prevalent.  Industrial facilities need a way to alleviate the problems caused by these increased temperatures and to mitigate the risk of failing electrical devices due to heat.

EXAIR Cabinet Coolers provide this solution using nothing but compressed air.

EXAIR Cabinet Coolers convert a source of compressed air into a very cold stream of air, capable of cooling a sealed enclosure.  They are mounted directly to the enclosure, feeding in air as low as 18°F (-8°C) to bring the internal temperature of the cabinet down to acceptable levels.  While the cold air generated by the Cabinet Cooler is fed into the enclosure, hot air is simultaneously removed, maintaining relative humidity inside the enclosure at 45%.

Rated for use in NEMA 12 (IP54), NEMA 4, and NEMA 4X (IP66) environments, EXAIR Cabinet Coolers are available in aluminum, 303 stainless steel, and 316 stainless steel.  No matter the material of construction, EXAIR Cabinet Coolers can provide 275 – 5,600 BTU/hr. of cooling capacity in industrial applications with ambient temperatures up to 125°F (52°C).  For hotter environments up to 200°F (93°C), High Temperature Cabinet Coolers are available.

In extremely dirty environments, Non-Hazardous Purge systems provide a continuous stream of air (1 CFM) into the enclosure, maintaining a positive pressure and preventing any dust intrusion.

Each system type and material are available to ship from stock*, allowing fast delivery to your facility and quickly solving an overheating condition of your devices.

Never do this! This setup forces dust and contaminants into the control panel, compromising the electrical components inside.

Fans and traditional air conditioners can effectively remove heat, but they provide no separation between the sensitive components inside of an enclosure and the dirty industrial environment outside.  Simply installing a fan or AC unit can allow dust, oil, and other ambient contaminants into the enclosure, leading the failure of the expensive equipment inside.  And, these solutions degrade over a finite lifespan (the Cabinet Cooler does not), they require routine maintenance (the Cabinet Cooler does not), and they need more time to install (Cabinet Cooler installation is fast and simple).  Curious how easy it is to install an EXAIR Cabinet Cooler?  Check out this video and see just how easy it really is.

For those applications without enough spacing to mount a Cabinet Cooler on top of the enclosure, Side Mount Kits are available.  These kits are also available from stock and are just as easy to install:

All EXAIR Cabinet Coolers are available with thermostat controls to regulate internal cabinet temperatures and compressed air consumption.  EXAIR thermostats feature a bimetallic contact strip to open and close the electrical circuit in response to air temperatures.  These thermostats quickly respond to changes in air temperature and are specifically suited for their intended use.  Preset for 95°F (35°C), a suitable temperature for most electronic devices, these thermostats are fully adjustable for specific application needs.

In the event a more sophisticated thermostat control is needed, Electronic Temperature Control units can be implemented.  These standalone units utilize a thermocouple to determine internal cabinet temperatures which display onto a digital readout.  Push-button controls on the digital readout board allow for easy modification of the internal cabinet temperature set-point.  When the desired internal temperature is reached, the Cabinet Cooler will turn off automatically.

Is it really that easy?  Can a Cabinet Cooler provide real cooling for sensitive devices and last for years without any maintenance?  Well, here’s an example:

(Click for larger view) The image on top shows year one of the Cabinet Cooler’s life, and the image on the bottom shows year six.

An automotive radiator manufacturer experienced a problem with an overheated motor drive, causing one of their production lines to come to a stop.  The root cause of the failure was a leaking refrigerant-based air conditioner, which failed and allowed water into the enclosure housing the motor controls.  When the water entered the enclosure, it shorted the motor drive and caused the production line stoppage. The new drive cost over $20,000 and a month of down time to purchase, receive, and install.

Following this failure, the customer searched for a more suitable cooling solution and installed an EXAIR model 4330 NEMA 12 2,000 BTU/hr. Cabinet Cooler System.  With an included thermostat control, this system provided proper cooling for the application without any need for required maintenance or potential to leak water into the enclosure.

Fast forward six years and this same customer reached out to EXAIR for another application.  During the conversation they mentioned the Cabinet Cooler they purchased many years before was still in operation, still providing proper cooling for the enclosure, and that no maintenance had been performed (Cabinet Coolers do not require routine maintenance).  Even in the dirty industrial environment of this manufacturing facility, the EXAIR Cabinet Cooler continued to function flawlessly.

When exploring industrial solutions, required routine maintenance is a common concern.  The cost of replacement components and time required to perform necessary maintenance weigh heavily on decision makers.  Fortunately, EXAIR Cabinet Coolers do not require any maintenance, and with clean, dry compressed air their lifespan can be 20 years or more.  There are no moving parts to wear out or routine maintenance services to be performed.

If you’re in need of a suitable cooling solution for an industrial enclosure, consider an EXAIR Cabinet Cooler.  They’re smaller than traditional AC units, faster to install, and require little-to-no-maintenance.  Feel free to contact an EXAIR Application Engineer with any questions, or fill out our online Cabinet Cooler Sizing Guide to have an Application Engineer contact you.
