5 Applications Suitable for a Cabinet Cooling Fan

when_a_cabinet_cooling_fan_is_the_best_optionSome of the most common solutions for cooling an electrical cabinet are air conditioners and air to air heat exchangers. However, certain applications allow a simpler and more cost-effective option. A cabinet cooling fan is an economical solution for an application that meets the following criteria:

  • The ambient temperature is lower than the desired temperature within the cabinet
  • The ambient humidity level is relatively low
  • The cabinet is located indoors
  • The cabinet is located outdoors with limited exposure to the elements
  • There is little or no risk of exposure to airborne contaminants
  • There is little or no risk of exposure to hose spray
  • There is no risk of exposure to corrosive materials

If the electrical cabinet is located outdoors in an extreme environment, exposed to corrosive materials, or in a location where water or cleaners are regularly sprayed, a closed-loop cooling system is required and a cabinet cooling fan is not appropriate.

5 Applications for a Cabinet Cooling Fan

Most cabinet cooling fans are rated NEMA Type 1 (for indoor use) or NEMA Type 3R (for indoor or outdoor use). Some of the most common types of applications where cabinet cooling fans are appropriate include:

  1. Audio/visual equipment – Televisions, stereos, and other A/V equipment generate heat that must be dissipated to protect the electrical components. A NEMA Type 1 fan is often acceptable for this type of application.
     
  2. Power distribution – Portable substations for power distribution often use filtered fans that are rated NEMA Type 3R. A substation might be used at a construction site, trade show, concert, or manufacturing plant.
     
  3. Lighting contactors – Used to control lighting loads for applications such as parking lots, hospitals, stadiums, auditoriums, airports and office buildings, lighting contactors can often be cooled with a cabinet cooling fan.
     
  4. Switchgears – Used in electrical power system to isolate electrical components, the fuses, circuit breakers, and other components in a switchgear are typically cooled with a NEMA Type 3R filtered fan solution.
     
  5. Industrial control panels – Wiring and junction boxes can be located indoors or outdoors and can often be cooled with a NEMA Type 3R cabinet cooling fan. In some cases, a non-metallic solution is the best option for this type of application.
