Face and Bypass Dampers for Plate Exchanger will adhere to the following:
 Factory installed dampers tested in accordance with AMCA 500.
 Dampers shall have airfoil blades, extruded EPDM Seals.
 Dampers shall have a maximum leakage rate of 4 CFM/square foot at 1” w.g.
(CLASS 1), and shall comply with ASHRAE 90.1.
 Provide factory-mounted modulating actuators(if selected) for dampers to aide
Plate Exchanger with frost control.
 Dampers shall be sized to provide economizer by allowing up to 100% of the
