I'm in need of my first free-standing, pad-mounted outdoor enclosure, 19" rack rails, 12-18 rack units, with about 400W of heat load inside, for use in the Massachusetts climate. What do people recommend as far as contruction, cooling/heating options, NEMA ratings, security options, etc. for this use? I was hoping to keep the inside temperature between 50 and 85 degrees Fahrenheit, although my worst-case components are rated for 41 to 104 F (4 - 40 C). If a full mechanical A/C system can be avoided, even better. A thermo-electric cooler would be nice. Thanks.
I came across this once. Seems interesting but we have never used it ourselves. 400 Watts is not much so I believe this unit may even be overkill. http://www.ellipticalmedia.com/raserhd.html On 6/17/2013 3:36 PM, Chuck Anderson wrote:

Alpha's Radium Minibays should be a good start of what to look at and seems to fit your requirements: http://www.alpha.ca/web2/products/enclosures/outdoor-enclosures-medium/item/... On Mon, Jun 17, 2013 at 12:36 PM, Chuck Anderson <cra@wpi.edu> wrote:

This is by far a "cheaper" option, but should work just fine. I'm about to do the same myself. Grab a used cab here - http://www.usedtowers.com/CABINETS/CABINETS.htm Some of those come with the factory huge AC systems built for thousands of watts of equipment inside, but if you're like me and will have 300-400 watts max, grab a non-cooled cabinet for cheap. Then pick up one of these guys and slap it on, buy the capacity you need. You can get them with a heating option as well, they're thermoelectric and very affordable- http://www.eicsolutions.com/thermoelectric-air-conditioners.php -- Jon Sands Fohdeesha Media http://fohdeesha.com/

"very affordable"? I looked at those and they cost more than twice the cost of the cabinet itself. But I might end up going with them anyway, 1500 BTU would cover the 400 watts I generate inside the cabinet, but I'm more concerned about the outdoor environment/solar heating effects. How many BTU should I add to account for that?
Woah, the last quote I got from them was less than half the price of a cab. I guess I'm cooling less equipment? What model are you looking at? On 6/17/2013 4:28 PM, Chuck Anderson wrote:

I have had success with the opposite approach using equipment rated from -40 C to +85 C (+185 F), no fans, sealed NEMA4 or NEMA12 Hoffman enclosures, cooling by equipment heat sinks. Ethernet switches and optics rated -40 C to +85 C This configuration has worked with the same equipment for at least 6 years in an environment where summer ambient temperatures reach 120-130 F, and winter ambient 0 F. Hoffman makes a 72" high NEMA12 enclosure with a swing-out 19" telco rack. On Mon, Jun 17, 2013 at 12:36 PM, Chuck Anderson <cra@wpi.edu> wrote:

Unfortunately, I have some specific non-commodity circuit boards I'm dealing with, so I have to accommodate their environmental requirements. On Mon, Jun 17, 2013 at 01:22:26PM -0700, david peahi wrote:
