Insulated Control Dampers

Greenheck’s ICD series of dampers was developed for applications where it is necessary to minimize the transfer of heat or cold penetration and reduce condensation. The thermally broken frame provides an insulating barrier in the ductwork. Thermally broken blades separate the warm and cold air inside the ductwork. Silicone jamb seals effectively seal the penetration of air from one side of the blade to the other.

Design FeaturesVariable Symmetric Blade Design (VSB)Greenheck’s Variable Symmetrical Blade (VSB) design uses a combination of three symmetrical blade sizes (4, 5, and 6 inch) to maximize the free area at any damper height by reducing blade stop height. Traditional damper designs use a single blade width that requires oversized blade stops, limiting free area when the blades are open. The VSB design allows for consistent operating characteristics regardless of airflow direction.

• Increases Mounting Flexibility - Symmetrical blades have identical operating characteristics regardless of airflow direction. This allows a Greenheck control damper to be mounted in either direction of flow, an advantage when installing with space constraints.

• Increases Free Area - Traditional damper designs with a single blade width require oversized blade stops, limiting free area when the blades are open (Figure 1). Greenheck is able to reduce blade stop height, which maximizes free area, and increases damper performance. AMCA certified pressure drop lets you know that the published data is accurate to help you better design your system.

• Reduces Actuator Torque - If an unsymmetrical blade closes against airflow, a large amount of torque is needed because the air distribution is unbalanced. Greenheck’s VSB design balances airflow on each side of a symmetrical blade, reducing the torque required to operate the damper. The use of symmetrical blades has allowed Greenheck to reduce the sizes and quantities of actuators used on our dampers.

The ICD series damper blades feature thermally broken airfoil shaped blade with polyurethane foam.

Parallel versus Opposed Blade OperationGreenheck’s ICD series dampers are offered with either opposed or parallel blade operation. Parallel blade orientation is typically used when the damper operates in two positions, open or closed. The damper blades open or close in the same direction. Opposed blade orientation is typically used on dampers that modulate airflow. Adjacent damper blades will open or close opposite one another.

Insulated Control Dampers

Design FeaturesFrameThere are four frame types available:• Quick Connect for easy connection to duct• Channel• Single Flange• Reversed FlangeThe ICD-44 features an extruded aluminum frame. The ICD-45 features an aluminum frame with two polyurethane resin gaps and insulated on four sides with polystyrene.

No Top or BottomICD series dampers are designed for installation in any position with the blades horizontal. As shown, the damper can be turned over so the actuator is on the left or right side.

Blade & Jamb SealsSilicone blade and jamb seals stay flexible in cold temperatures.The ICD-44 features silicone blade seal with 304SS jamb seals with optional silicone jamb seals. The ICD-45 features silicone blade and jamb seals.

LinkageGreenheck’s ICD series dampers have blade linkage concealed in the insulated frame. This prevents any transfer point for cold or heat, unlike some of our competitor’s products. The linkage is engineered to accurately control each and every blade without need for adjustment.

BearingsDual bearing with acetal inner sleeve and flanged outer bearing features no metal-to-metal or metal-to-plastic contact.

Damper Performance Testing Criteria

Thermal PerformanceDuring thermal performance test, per ASTM Standard C1363-97 conducted at Architectural Testing Laboratories (ATI), the ICD-45 outperformed competitor’s thermally broken dampers. (Report #53166.01-201-46)

Dry Ice TestThe thermal breaks in the damper blades and frame reduce the transfer of heat from the “cool side” to the “warm side”. When compared to a standard airfoil blade design, ICD airfoil blade, with thermal breaks, prevents ice from forming on the opposite side of the blade.

Leakage TestICD series dampers meet the IECC (International Energy Conservation Code) requirements for damper leakage ratings of at 3 cfm/ft2 @ 1 in. wg (54.8 cmh/m2 @ .25 kPa) or less when integral to the building envelope. Leakage testing was performed at Environ Laboratories at a temperature of -40°F. The ICD-45 was rated at less than 3 cfm/ft2 @ 1 in. wg (54.8 cmh/m2 @ .25 kPa) or 8 cfm/ft2 @ 4 in. wg (146.3 cmh/m2 @ 1 kPa).

Comparing a 36 in. x 36 in. (914mm x 914mm) damper, Greenheck’s ICD series has the lowest leakage in the industry.

When comparing a 24 in. x 24 in. (610mm x 610mm) damper, Greenheck’s ICD series has the lowest pressure drop in the industry which means lower fan cost or smaller damper size required.

Pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft3 (1.201 kg/m3).

Actual pressure drop found in any HVAC system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVAC system.

Figure 5.3 Illustrates a fully ducted damper. This configuration has the lowest pressure drop of the three test configurations because entrance and exit losses are minimized by straight duct runs upstream and downstream of the damper.

Figure 5.2 Illustrates a ducted damper exhausting air into an open area. This configuration has a lower pressure drop than Figure 5.5 because entrance losses are minimized by a straight duct run upstream of the damper.

Figure 5.5 Illustrates a plenum mounted damper. This configuration has the highest pressure drop because of extremely high entrance and exit losses due to the sudden changes of area in the system.
