Round Variable Volume Dampers - WRS - WRD
The Waterloo round variable volume dampers (WRS and WRD) are designed to deliver a controlled air volume, regardless of the pressure within the ductwork. These controllers combine advanced measurement techniques with flexible motor control for precise air handling in HVAC systems.
Introduction
These controllers consist of a Waterloo measuring cross, a control damper, and an external motor with an integrated controller that regulates the air volume within preset limits. The units are configurable for connection to a BMS control system and can be set as constant volume controllers if needed.
Features
- Flexible configuration: Adjustable for air speeds of 2 – 10 m/s and up to approximately 10% accuracy.
- Universal mounting: Suitable for installation in any position with minimal space requirements.
- Adaptability: Factory settings can be adjusted after installation to meet specific needs.
- Compatibility: Can be linked to controllers from various manufacturers.
Product Description
- WRS: Single-wall air volume controller for standard installations.
- WRD: Double-wall insulated air volume controller for increased sound insulation and energy efficiency.
Technical Specifications
- Materials: Casing and control damper made of galvanized steel, with a rubber seal on the control damper.
- Dimensions: Available in diameters of Ø 100, Ø 125, Ø 160, Ø 200, Ø 250, Ø 315, Ø 355, and Ø 400 mm to fit various duct systems.
