Atlantis 500R

Overview

The Atlantis-Series is an attractive alternative to air-cooled Load Banks. It is perfectly quiet and cool running; extremely compact and may be installed in otherwise unutilized space. And it is virtually maintenance free. The Atlantis-500 is ideal for data center chiller system commissioning. With its large 4-inch water connections and minimal pressure drop, the Atlantis will accept the high water flows required for limited temperature rise, typically 12.5°F. Multiple Atlantis Load Banks can be networked to form large systems controlled from a single operator interface. In addition, the Atlantis shares the same control architecture with the Simplex Nautilus-250 permitting any number of Atlantis and Nautilus Load Banks to be networked together.

Features

General

Multiple Atlantis 500R Load Banks can be networked to form large systems controlled from a single operator interface. In addition, the Atlantis shares the same control architecture with the Simplex Nautilus-250, 250kw water-cooled load bank, permitting any number of Atlantis and Nautilus Load Banks to be networked together.

Control System

Digital control portable touchscreen with V-A-Hz-KW display.

Load Cell

Each load cell includes sensors for normal operation, cooling failure, overpressure and loss of flow / low water level.

Load Elements

Each load cell includes sensors for normal operation, cooling failure, overpressure and loss of flow / low water level.
Load elements are water immersion power resistors. Load control is via magnetic contactors with branch circuit power fuses.

Control Power

Control power for the Load Bank is provided by 120V, transformer isolated, internal power supplies. Control power is derived internally from the connected power source or from an external source./td>

Power Distribution

Power distribution within the Load Bank is via a 3-phase main copper load bus. Field connections are via cam-lok type connectors.

Cooling Media

The Atlantis 500 R is suitable for use with a variety of cooling media, including city water (nominal 50 PSI), closed loop chilled water systems, heat exchanger systems, pumped water from natural sources (lake, river, etc.) or brine or sea water (requires optional nickel alloy construction and elements)
