Constant air volume regulators

Contents Circular regulator model RCCK Description 2 Rectangular regulator model RCQK Description 13

Description The circular constant volume regulator type RCCK is a control element which works independently of the pressure without an external power supply. It can be regarded as a self-actuating duct damper, as it delivers a required volume of air regardless of changes in system pressure. In consequence, the controller overcomes the need for system balancing and ensures constant air flow in service.The RCCK incorporates an adjustment device that allows to modify manually on site the air-flow pre-adjusted at the factory. 1.

Dimensions Dimensions The RCCK are designed to pressure connection directly to the duct, as its diameters are standardized as per ISO Norms, they can be installed either in vertical or horizontal position.

PRESSURE, ACCURACY AND REGULATING BAND The regulator RCCK operates reliably from a minimum pressure difference, which depends on the air velocity (see diagram below), to a maximum pressure difference of 1000 Pa. The accuracy of the adjusted air-flow is within a tolerance of +-10%. Accuracy will be lower than indicated if the air flow profile is not uniform or is distorted by bends, sharp edges or bottlenecks that can disturb the air flow uniformity in the duct. We recommended, therefore to optimized the work condition...

Adjustment and installation Adjustment 1 - Control damper box setting control 2 - Part marking 3 - Label airflow graduation 4 - Mechanism box Steps to set the flowrate on the control damper: Turn the setting control (1) on the mechanism box side (4) until the marking part (3) is set to the required air flowrate (2). The RCCK are designed to pressure connection directly to the duct, as its diameters are standardized as per ISO Norms, they can be installed either in vertical or horizontal position. The tightness is getting by means of rolling rubbers ring seals in both ends. The adjustment device...
