Radium Enclosure Series

Scalable, environmentally controlled enclosure system
Fully integrated agency certified system
Ideal for remote optical transition applications
High capacity 24 or 48Vdc 3000BTU air conditioner
Natural gas or propane generator system supports critical communications
Reduces operational and recurring costs

The Radium MiniBay™ is a highly configurable enclosure system supporting a wide range of applications including bulk power, hub, secondary hub and remote terminal. Also ideal for remote optical transition applications including optical amplification, downstream DWDM demultiplexing, narrowcast combining and return path aggregation providing services to remote communities. The Radium MiniBay when configured with 48Vdc air conditioners or 48Vdc fan cooling options and collocated with an AlphaGen™ Curbside generator offers near indefinite lengths of standby operation upon loss of AC service while maintaining the correct operating conditions for communications electronics. The Radium MiniBay is configured to order.

Fans and Filters
The most basic thermal management system supporting the MiniBay utilizes conformal-coated, variable speed and alarm monitored fans with electrostatic air filters providing up to 500W thermal dissipation. This configuration has a NEMA 3R rating.
• Variable speed controlled DC fans continue to operate during a utility outage
• Conformal-coated fans
• Electrostatic and washable air filters
• Field replaceable fans

Heat Exchanger
An airtight rear door and a heat exchanger equipped hinged front door providing over 500W thermal dissipation. With a 500W load, the internal ambient temperature will not exceed 15 to 27°F above external ambient. With a 250W load, the internal ambient temperature will not exceed 7°C or 12.6°F above external ambient. This configuration has a NEMA 4X rating.
• Heat exchanger heat pipe technology provides efficient thermal transfer
• Minimizes internal temperature rise above external ambient
• Variable speed controlled DC fans continue to operate during a utility outage
• Field replaceable fans

DC Air Conditioner
For applications requiring the most reliable below ambient cooling and dehumidifying system for supporting seamless performance through extended utility outages. Cooling capacity 878W dissipated at 43°C outdoor ambient allowing a Maximum* internal ambient of 40°C / 104°F.
• Variable speed brushless motor 24/48Vdc compressor system assures optimum efficiency over the full range of thermal loading and ambient temperatures
• 3,000BTU @ 43°C/110°F rating
• Redundant conformal-coated fans have >50,000hrs of life and low voltage disconnect circuitry

AC Air Conditioner
Ideal for applications requiring cooling and dehumidifying with little or no standby runtime performance. Cooling capacity 1464W dissipated at 43°C outdoor ambient allowing a Maximum* internal ambient of 40°C / 104°F.
• 5,000BTU @ 43°C/110°F rating
• Washable electrostatic filters
• 240Vac
