From ancient times humans have sought ways to cool themselves down, from the invention of the manual fan in ancient times to the modern A/C systems that are used to cool down entire buildings. Anymore these days there is a cooling system for just about anything; gaming PC’s have there own cooling system, personal fans that mist water for cooling down people, climate-controlled boxes for artifacts in museums, etc. But what about your electrical cabinets in your facility? Electrical cabinets that overheat can cause expensive shut downs and lead to unsafe operations where the doors are left open with fans blowing in. When it comes to electrical cabinets there are two well-known ways that are used to cool down electrical cabinets which are fans and A/C units. But there is a third option you can go with which is EXAIR’s Cabinet Coolers.
Cabinet Coolers are compressed air powered cooling units that utilize a source of compressed air and vortex tubes to cool down enclosed areas. But why would you choose a Cabinet Cooler over an A/C coolant driven system? Each system has pros and cons that can be weighed against each other.
A/C Coolant Driven Systems:
Pros:
Can produce higher cooling loads effectively
Cons:
Expensive up front
Constant maintenance
Cabinet Coolers:
Pros:
Inexpensive upfront cost, lower lifetime cost
No moving Parts / No actual maintenance
Cons:
Smaller range for effective cooling
A/C Units operate in most cases using a chemical known as Dichlorodifluoromethane more commonly referred to as Freon (Freon is a registered trademark of Chemours Co.). By compressing and decompressing the liquid you can cause significant temperature drops in the surrounding air that can be blown into an area. This process requires a lot of moving parts that will eventually wear out and need to be replaced at a cost. Cabinet Coolers don’t have that issue, since they use vortex tubes there are no moving parts to wear out. As long as you provide clean dry air to a Cabinet Cooler the system will run indefinitely. Another thing to keep in mind is that although Dichlorodifluoromethane is a safer version of the older CFC’s , the chemical is not completely safe. Freon can be harmful to the environment as it can breakdown ozone, and due to its its density it will displace oxygen and can cause rapid suffocation.
Cabinet Coolers use compressed air, air which we breath and is all around us. So, no hazards with its energy source.
Lastly, although A/C units are cheaper to run they are much more expensive upfront cost and upkeep cost. This means in the long run it is actually cheaper to use a Cabinet Cooler because it does not have any upkeep cost for maintenance and repairs, along with being much cheaper to begin with.
