Round Duct System RR-COMPLETE Description In modern architecture, sheet metal and spiral ducts of air-conditioning systems are often incorporated in the design of the room. Emphasis is often placed deliberately on parts of the supply system. In this visible installation of the ventilation ducts, it is a good idea to integrate volumetric flow controllers, duct silencers and air diffusers into the ducts. In order to be able to offer planners a technically outstanding system, which can also be well integrated into modern architectural concepts, we have developed the round duct system type...

Round Duct System RR-COMPLETE Volumetric flow controller model VRA-RR Description A volumetric flow controller is used for pressure-independent volumetric flow regulation in ventilation and air-conditioning systems. It is used to keep the volumetric flow constant (CAV) within specified limits or to control it variably (VAV) as a function of a command variable, for example a room temperature controller, DDC or bus system. For constant volumetric flows, the operating stages CLOSED/Vmin/Vmid/Vmax/OPEN are available in stage operation, controlled via relays or switches. The housing, measuring...

Round Duct System RR-COMPLETE Attention, the following specifications are important for the programming of the volumetric flow controllers: - this table merely specifies the complete measuring range of the controller (volumetric flow range) - If the customer absolutely wants a calibration curve different from 12 m/s, it must be specified! - When the air volume drops below the Vmin shown in the chart, the correct functioning of the volumetric flow controller is no longer guaranteed! - If only one air volume is specified in the order (as Vmax value), the volumetric flow controller will be...

Round Duct System RR-COMPLETE Volumetric flow restrictor DKA-MKA-RR Description For quick, easy control of the supply air volume, the DKA-MKA-RR was especially developed for the round duct system RR-COMPLETE. The round, manually adjustable volumetric flow restrictor DKA-MKA-RR is suitable for installation in round supply air and return air ducts according to DIN 24145 or 24146. It is used for regulating the volumetric flows in air-conditioning installations. The integrated volumetric flow controller measuring cross type is mainly used for measuring the air volumetric flow downstream of the...

Round Duct System RR-COMPLETE Round Duct Diffuser Model DBB-RR The round duct diffuser DBB-RR consists of a round duct with integrated, linear nozzles, which can also be adjusted subsequently by hand, with integrated hit-and-miss damper, which allows the air to be blown absolutely uniformly over the entire diffuser area. The centrally arranged blades in support profile sections ensure that the free cross-section at every blade is the same. As a result, the noise level and pressure are not affected by changing the blade position. In heating mode, this allows a large penetration depth, thus...
