- Made in America
Customer Benefit
- The enclosure provides protection against dirt, rain, sleet, snow, windblown dust, water
- Designed to operate in the most extreme temperature ratings: -40°C to +50°C (122°F)*1
- Saves an average of $10,000 - $15,000 per year in HVAC costs alone when compared to an industial control building or MCC room with cooling improvements*2
- Enclosure prevents thermal shock to VFD components when starting under extended shutdown situation in extremely cold ambient
- The innovative air-flow technique eliminates filters, the need for frequent filter replacement*3
- No building required, saving construction and development costs associated with E-houses or industrial buildings
- Self-sufficient enclosure. Three cables in, three cables out. No external 480V or 120V connections, only utility mains, control cables, and motor leads.
- The enclosure is classified as weatherproof, free-standing equipment, eliminating the need for real estate improvement that attracts property taxes
- The enclosure is designed, assembled and tested in the U.S.A.
