Interior literature tray with key tabs NEMA Type 4 Temperature Controlled Enclosures
These enclosures are perfect for housing fire-panels installed on the outside of buildings, DVRs in remote locations, or wherever you wish to protect the equipment that protects YOU!
If you have questions about the NEMA or UL ratings, please give us a call at 1-800-473-0213. In order to keep proper NEMA and UL ratings installers must keep the AC/Heater unit upright at all times, and explicitly follow all manufacturers' installation instructions, including using water-tight fittings on any holes cut into the enclosure.
Mier’s Temperature Controlled Enclosures are built of durable 16-gauge steel and are covered with a protective outdoor, baked-on, powder-coat finish. These metal boxes are designed to provide a degree of protection from rain, sleet, snow, ice, dirt, and dust.
Enclosures ordered with an air conditioner and heater (ACHT) come with holes pre-punched on the left side for easy and quick mounting of the ACHT unit. All of the enclosures come with studs for a Tamper Switch in the top right.
There are no holes (other than those for the ACHT Unit) or knockouts in the enclosure. Exterior mounting brackets, with two holes each, are on the top and bottom of the enclosure. The ACHT units ship on a separate skid from the enclosures and must ship via LTL carrier.
