Air flow regulator REACT V

Variable flow damper Variable or constant flow regulation Rapid access to readings via the controller display Quick setting of parameters Analogue controls or Modbus control Can be easily anti-condensation insulated in the duct system Variants: Circular connections: Ø100-630 mm Rectangular connections: 200x200-1400x700 mm Available with spring return actuator Technical description General • Intended for flow regulation of comfort ventilation. • Moist, cold and aggressive environments must be avoided. • Can be installed in both supply and extract air systems. • Pressure-independent, but does require a minimum pressure drop of 10 Pa across the damper. • The minimum air flow must be considered during design. • For good regulation, a minimum difference between Vmin and Vmax of 20% of the product’s Vnom is recommended. Design • Motor: Normal or spring return. • Options for selection of spring return (Order item): – Normally closed (NC). – Normally open (NO). • Integrated air flow sensor. • Analogue controls 0(2)-10 V or Modbus control. Circular variant: • Connection: Ø100-630 mm. • Always supplied with dust protection. • Motor shelf with 30 mm spacer to facilitate condensation insulation of the duct system. • A factory-insulated model available on request. Rectangular variant: • Connection 200x200-1400x700 mm. • Other sizes are also available on request. Functions • Variable or constant flow regulation. • Measurement of air flow. • Display for direct reading. • Settings can be made directly on the controller with the help of a screwdriver. Materials and surface treatment • All sheet-metal parts are galvanized sheet steel (Z275). • Measuring rods are aluminium.
