Coastal and corrosive HVAC applications will benefit with a new critical environmental damper series that combines the strength of stainless steel and protection of anodized aluminum to combat salt water elements.

The CD50CE damper from Ruskin of Grandview, MO, is Air Movement and Control Association (AMCA) licensed as Class 1A. It also complies with the International Energy Conservation Code (IECC), due to its use of low-leak extruded aluminum. Damper features include low-maintenance, non-corrosive bearings and shake-proof linkage; airfoil blades for high-velocity HVAC systems, low pressure drop and quieter performance; and mechanically-fastened blade edge seals.The Ruskin® CD50CE (left) and TED50CE (right) critical environment dampers.

The thermal-efficient TED50CE damper eliminates thermal transfer and the potential for condensation. The design also meets the IECC, features the same non-corrosive bearings and shake-proof linkage as the CD50CE, and includes twin seals to ensure no thermal path.
