UNDERFLOOR PRODUCTS E3

Transcription

1 E3 Introduction: Krueger s round diffusers are designed to seamlessly integrate into any underfloor installation. The units are made of a durable and long lasting cast aluminum construction. The can be used in either a VAV or constant volume application and is available in two sizes and a variety of plenum options. The plenums are pre-painted flat black to conceal them from view through the diffuser. MOEL - Cast Aluminum ound iffuser for Underfloor with Helical Air Pattern EATUES Available in or 10 round nominal sizes. Ships completely assembled and is easily installed without removal of the floor tile. eatures a directionally adjustable 360 air pattern. 180 air pattern available on units. urable cast aluminum construction to withstand any application. eatures a 1250 lbs. load rating. Manual airflow adjustment that provide tight shut off. Conforms to NPA 90A fire requirements. Provided with optional factory painted flat black steel plenum. Provides silent operation less than 17 NC at 100% capacity. When ordered alone, works in 6 raised floors. With plenum option, compatible with raised floors. PLENUM OPTIONS 0 - No plenum for constant volume. P - Open inlet to underfloor plenum for constant volume. - Elliptical inlet that accepts a 6 round compressed duct connection. V - VAV inlet with 0-10 Vdc proportional actuator. H - Heat/Cool changeover unit has an elliptical inlet to accept a 6 round compressed duct connection on one side that is ducted to a underfloor fan powered terminal unit. On the adjacent side is a VAV inlet with 0-10 Vdc proportional actuator for cooling operation. NOTE: Units shipped with the V and H plenum options ship with a quick connect cable for both data and power.

Underfloor diffusers shall be Krueger model. The diffuser shall be constructed of solid cast aluminum and meet NPA 90A requirements. The diffuser shall have a maximum load rating of 1250 lbs. The diffuser, damper assembly, and dirt catch pan are shipped fully assembled and can be securely installed in floor tile by turning the center screw and allow retention bar to clip to bottom side of floor tile. The diffuser shall not be removed without use of hexagonal key. The floor diffuser shall be designed such that the access floor panel is not removed from the floor system for installation of the diffuser. The diffuser core design shall produce a vertical, high induction helical air pattern that complies with ASHAE Standard 62. The diffuser shall have a sliding manual damper capable of adjusting the volume from full closed to full open. The diffuser shall be factory painted with a powder coat finish. The - shall be provided with an optional plenum. The components. The plenum shall be provided with an ellipsoid duct connection that will accept a standard six inch duct. The -P shall be provided with an optional plenum. The components. The plenum shall be provided with one side open to the underfloor plenum for constant volume operation and to control sound transmission from the underfloor plenum to the occupied zone. The -V shall be provided with an optional plenum. The components. The plenum shall be provided with a an actuated air valve damper controlled by a 90-degree stepper type motor having no stops, springs, gears, belts or linkages, and shall rotate continuously in one direction (not reversing) to minimize wear. The motor shall directly drive the damper blade. The damper assembly shall be rated and tested for a life of 100 million cycles (factory tests of at least 20 million cycles at normal operating speeds are required). A proportional 0-10 Vdc control signal can be used to modulate the damper position to adjust the volume of air in response to the thermostat signal.
