ULTROL CPA Control Panels - Airline Series
Applications
ULTROL Airline Series Control Panels (CPA) are designed and built to the high-technological standards required by today's engineers for precise airflow and environmental pressure control.
Several standard models are available for the measurement, indication, and control of duct static pressure, variable volume supply-and-return fan synchronization, laboratory or clean room static pressure and flow, as well as, manual control and alarm systems.
The panels are normally supplied as components in a complete airflow measuring and control system which includes flow and pressure sensors. See ULTRAC Specifications.
Description
ULTROL Airline Panels are constructed to industrial process plant standards to provide long-term, trouble-free operation with minimum maintenance. Equipment is installed in NEMA 1 enclosures with removable, internal instrument-mounting panels.
Sizes vary from 12" x 16" to 36" x 48" as required.
Standard specifications describe the equipment most often furnished. Panels will vary according to specifications for a particular system.
Airline Series Panels may be combined to economically meet a project specification.
