Air flow regulator OPTIMA-LV-R & RI

Description OPTIMA-LV-R (RI) is a Variable Air flow Volume (VAV) contoller installed in circular ducts for demand oriented ventilation. It can operate in large air velocity range and it is especially intended for precise flow control at low air flow velocities down to 0,2 m/s. It is pressure independent in range of 2 Pa to 600 Pa. The electronic controllers can operate for air supply or air extract. Individual control operation or Master/Slave combination of multiple controllers is possible. Highlights • Extends the range of VAV controllers in low air flow velocity part – down to 0,2 m/s • Adaptive measurement probe for high efficient dynamic pressure readings on whole velocity range • Advanced algorithm for appropriate control at subliminal duct static pressure • Operable at ∆p range 2 Pa … 600 Pa • Unprecedented control ratio Vmax/Vmin = 30/1 (0,2 m/s … 6 m/s) • Lowest possible cross section restriction for given pressure - /flow parameters > > low pressure loss, low noise • No straight duct in front or behind the VAV controller required. Installation immediately behind or in front of elbow or tee duct piece is possible. • Accuracy: app. 5% defiation from measured value * • Leakage class 4C • Full set of operation and override functions (Open, Close, Vmin, Vmax) • On-board Bus communication port available NOTE: * The air flow controller OPTIMA-LV-R (RI) utilizes a special control algorithm to protect the actuator from mechanical damage in low velocity flow. Design# Material Composition The VAV controller has galvanized steel sheet circular casing as well as damper blade. The galvanized steel blade shaft can be turned in reinforced polymer bearings.
