Economics plays a role in terms of upfront installation cost, ongoing operational energy cost, and future maintenance needs. Technologies with more moving parts may perform well but will typically have a higher lifetime total cost because they may fail at some point. Simpler technologies like vortex coolers are very reliable but may consume a significant amount of compressed air. Figure 3: Vortex coolers are compact and reliable devices for cooling enclosure interiors, useful for harsh environments and where compressed air is available. tional heating factors (especially a heat load from sun exposure). * Understanding the availability of utilities like electricity and/or compressed air. * Selecting the solution(s) and sizing them.

They can take advantage of these resources to find the best technical and most cost-effective solutions for providing thermal management that protects electrical and electronics installed within enclosures from the effects of temperature and moisture.
