 The Gemini EP provides an array of ion emitter modules, attached to the cleanroom ceiling grid and connected to a controller in a daisy-chain
manner using modular telephone type wire and connectors. The system's flexibility allows for ease of installation and blanket area protection.
Gemini EP features superior flexibility that allows easy positioning of
emitter modules in the ceiling or where they are most needed in the cleanroom. The system is designed to maintain unidirectional airflow. The Gemini EP emitter modules can be adjusted individually using a
handheld remote control transmitter or all the emitter modules can be adjusted together using the system controller.
Each emitter module contains emitter points, switching power supplies and Microcontroller Intelligence, designed
to maintain critical ion output and balance. Each module produces both positive and negative ions, which neutralize
electrostatic charges in the work area. The cleanroom’s unidirectional airflow sends the ions downward through the room. In this way, the Gemini EP System modules provide blanket protection, helping to keep all surfaces and
product free of static charge.
Each emitter module stores a balance reference value and an ion output current reference value, a patented feature
of the Gemini Systems. These values are used by automatic balance control and automatic ion output current control circuitry to ensure stable operation and consistent performance. Profile emitter modules send fault condition
information to the system controller, and from the controller to the PC monitoring software provided with the system. Gemini EP system functions are maintained by a micro controller-based communication network. The
System Controller maintains contact with every Emitter Module to verify conditions. The system displays “System OK” to provide assurance that no fault conditions exist. Should a system fault occur, the controller identifies the
fault on its display. To adjust each module’s ion output and balance, the remote transmitter is used. To adjust the entire group, the system controller is used.
