Air Core Reactor

Requirements For The Use Of Air-Core Reactors

• No metallic objects forming closed loops (re-bar, ground grid, ceiling joist, etc.) shall be within one diameter of the air core reactor. Typically, this would create a 12 foot x 12 foot area (assuming the air core reactors are stacked) with the air core reactor at the center. If the air core reactors are not stacked, more floor area would be necessary.

• Aluminum and sectionalized gasketed steel enclosures can have clearances down to 1/2 diameter between enclosure walls and the air core reactor.

• If re-bar directly below the air core reactor is of concern (or other metal forming loops), pedestals may be used to raise the reactors away from the floor, ceiling or ground. If the reactors can not be raised due to height limitations, a 12 foot x 12 foot x 3/8″ thick aluminum plate can be placed directly under the reactor for shielding.

• If health effects are of concern, the reactor manufacture should be consulted to determine the distance requirements to meet safe magnetic field levels. As a general rule, the magnetic field 1/2 diameter from the reactor will be approximately 30 Gauss. A thin wall enclosure will supply no shielding effect. To get lower fields, more space can be provided, or a 3/8″ Aluminum curtain (shield) around the reactor could be used. If personnel can come in contact with the aluminum curtain, a double wall enclosure may be be required due to excessive temperature of the Aluminum and the danger of burns.
