The Smart Bypass Damper from EWC Controls is a digital differential pressure controller with an integrated PI loop and intelligent software. The Smart Bypass Damper is the only industry bypass solution that can automatically measure, monitor and maintain the designed operating static pressure of the HVAC system in all modes of operation. How the Smart Bypass Damper Works:
The Ultra-Zone Smart Bypass Damper captures (with the push of a button) the total static pressure of the HVAC system during non-zoned mode, and modulates to maintain that same static pressure value, during zoned mode. As individual zone dampers open or close, the HVAC system static pressure will fluctuate. In order to maintain the true static pressure of the HVAC duct system during zoned HVAC operations, a bypass duct with a reliable bypass damper and a smart motor actuator must be installed. No other bypass damper is easier to setup, than the Ultra-Zone Smart Bypass Damper. ewccontrols.com
For both zoning and ventilation applications, Honeywell TrueZONE® Dampers are the ideal choice. Installation has been designed with the technician in mind, and the quiet, efficient operation helps ensure satisfied customers for years to come. For fast, accurate installation with no callbacks, the TrueZONE Damper has you covered with a range of features that simplify installation in every application:
• Adjustable Range Stops — Easy to understand and set by utilizing a push-in lever. They’re used to bleed air into the zones which helps lower pressure and reduce noise.
• Mechanical Position Indicator — Easy viewing through a clear window.
• Push-In Terminals — The same easy wiring design used on TrueZONE Panels. No tools needed, has space for two wires.
• LED Indicator Lights — Red indicates the damper is closed and green indicates open (used in 3-wire applications)• Taping Flange — Lets technician position insulation under it before sealing with foil tape. forwardthinking.honeywell.com
Fahrenheit’s Combination Zone Relief Damper (CZRD) by Performance Aire, is a patented product that eliminates the need to install a bypass duct and damper in a zone control system. This is accomplished with a built-in static pressure relief mechanism that will modulate open once the static pressure within the duct has reached an unacceptable level. (Factory set at 0.3”WC)
The CZRD is the answer to many installation problems such as:
• Space limitations installing a bypass
• State regulations restricting a bypas
• Added cost of labor and materials to install a bypass. performanceaire.com
Ruskin, an authority in air control products, has invested in solutions for extreme conditions, specifically the Louver EME6325D and CD60 Control Damper. Engineers and architects know that the best approach to attacking an extreme situation is to prepare for all the risk factors, meaning designing buildings that can withstand high winds and other known dangerous circumstances.
The Louver EME6325D, has been designed and tested to protect air intake and exhaust openings in building exterior walls from direct water penetration, even in the most extreme weather conditions. The EME6325D uses its patented vertical blade design to stop wind-driven rain and wind-borne debris from entering commercial buildings. It meets and surpasses the Florida Building Code for use in the High Velocity Hurricane Zone and is Miami-Dade Approved. Furthermore, the High Velocity Capacity louver allows for smaller louver sizes, reducing cost. The EME6325D is hurricane rated for the most severe water conditions meeting TAS100A water performance.
Manufactured of aluminum, Ruskin Louvers can be specified with a variety of options in a broad array of architectural finishes. ruskin.com
