Honeywell: Zoning Dampers
The Honeywell HVAC Zoning Temperature systems consist of a number of components, such as thermostats, zone temperature controllers and zoning dampers. The zoning dampers are extremely important, as they work with the actuator towards adjusting and further controlling your HVAC zoning system.
Their HVAC zone dampers consist of a number of models, each with its diverse features and functionality. These are the ZD Rectangular Dampers, ARD Round Dampers, EARD Dampers (Economizer Automatic Round Damper), MARD Dampers (Modulating Automatic Round Dampers) and SPRD Dampers (Static Pressure Regulating Dampers). Let’s take a look at these models and point out there features, functionality and the applications they work best in.
The ZD Rectangular Damper series consists of power close, spring open damper models made out of solid extruded aluminum, which protects them from corrosive elements or contaminants that could hinder the damper’s actions. You don’t need a lot of knowledge and skills in order to install the ZD Rectangular Damper yourself, since it only needs two wires and you benefit from a helpful and reliable mechanical visual position indicator.
The ZD series consists of a large number of parallel blade dampers of different sizes and of either a square or rectangular design. The models are named after the series’ initials and their width and height in inches. Here’s a complete list of all ZD rectangular Zone Dampers: the ZD10x10 parallel blade damper, the ZD10x12 parallel blade damper, the ZD22x6 parallel blade damper, the ZD24x10 parallel blade damper, the ZD24x12 parallel blade damper, the ZD24x14 parallel blade damper, the ZD24x16 parallel blade damper, the ZD24x6 parallel blade damper, the ZD24x8 parallel blade damper, the ZD24x18 parallel blade damper, the ZD24x20 parallel blade damper, the Honeywell ZD24x22 parallel blade damper, the ZD24x24 parallel blade damper, the ZD26x10 parallel blade damper, the ZD26x12 parallel blade damper, the ZD26x14 parallel blade damper, theZD26x16 parallel blade damper, the ZD26x18 parallel blade damper and the HZD26x20 parallel blade damper.
The above are just some of the more common sized zone dampers from them, but the manufacturer also offers model that range from 28 inches wide and 24 inches high or smaller 6x6 models, with either a square or a rectangular design. Choose whichever size you need, so you will be able to perfectly fit your damper to your HVAC system. There is no HVAC system size that the company doesn’t have covered by at least one or two zone damper models.
The ARD zone dampers also come in a large variety of sizes, ranging from 5 to 18 inches. The ARD power close, spring open round dampers feature a low leakage gasket, a mechanical visualization positioning system to aid you in manually installing the device, a reinforced blade construction that increases the dampers life span and the same universal motor used by the ZD series dampers (thus the interchangeability between the two series). The ARD zoning dampers are more common in fresh air applications in home HVAC systems. The series consists of the following models: the Honeywell ARD5 round automatic damper, the ARD6 round automatic damper, the Honeywell ARD7 round automatic damper, the ARD8 round automatic damper, the ARD9 round automatic damper, the ARD10 round automatic damper, the ARD11 round automatic damper, the ARD12 round automatic damper, theARD13 round automatic damper, the Honeywell ARD14 round automatic damper, the ARD15 round automatic damper, theARD16 round automatic damper, the ARD17 round automatic damper, theARD18 round automatic damper. The number after the ARD acronym means the inch size of the damper.
Honeywell EARD (Economizer Automatic Round Damper) zoning damper is not as widely used as the ZD or the ARD series, nor does it consist of so many varied models. The EARD is in essence a 6” round design damper that uses a 24 VAC spring closed and powered open motorized system. Ventilation, fresh air intake, combustion makeup and air conditioning is where the Honeywell EARD finds usage. The EARD models can be used in other HVAC systems, especially with other components like ventilation systems, actuators, control panels or thermostats. Some of the model’s features include an adjustable damper position range, structure made out of galvanized steel for a corrosion proof body, a quite operation measurement, the ability to be field-converted to a power closed/spring return open damper, a leakage system, crimped and uncrimped ends and the ability to connect to any rigid or flexible round duct.
The MARD series (Modulating Automatic Round Dampers) have found great use in light commercial applications that don’t exceed 2” W.C. sizes and in household HVAC appliances. The MARD models are being powered by power closed or power opened, bi-directional motors. These dampers have been primarily used in larger zone systems, or as a bypass damper when used in combination with a SPC. The series includes the following models, the number after the MARD acronym reflecting the inch size of the damper: the MARD 5 round modulating damper, the Honeywell MARD 6 round modulating damper, the Honeywell MARD 7 round modulating damper, the MARD 8 round modulating damper, the MARD 9 round modulating damper, the MARD 10 round modulating damper, theMARD 11 round modulating damper, the MARD 12 round modulating damper, the MARD 13 round modulating damper, the MARD 14 round modulating damper, the MARD 15 round modulating damper, the MARD 16 round modulating damper, the MARD 17 round modulating damper and the MARD 5 round modulating damper.
Last but not least, the Honeywell SPRD series consists of zoning dampers of round or rectangular shape, using a single-blade barometric relief system. The damper is mechanical-operated and has no electrical connections. They can be used in combination of a SPC (static pressure control) system, in case the application it is employed in has a higher pressure then 2000 cfm. The series includes model sizes ranging from 6 to 20 inches and either round or rectangular designs, which ever suits your HVAC application better.
