Info and Specifications for Canyon Air Products’ Induction Units

Principle of Operation

A. Pre-conditioned primary air enters the primary air plenum. This air passes over internal baffles for sound attenuation prior to entering the nozzles. A balancing damper is used for volume control.

B. The primary air exits the primary air plenum through efficiently designed aerodynamic nozzles. The smooth laminar flow from the nozzles creates a negative pressure in the mixed air plenum.

C. The negative pressure in the mixed air plenum induces room air across the cooling coil.

D. The primary air is mixed with the conditioned room air and discharges from the mixed air plenum and into the space.

Specifications

Induction units shall be manufactured by Canyon Air Products Inc. (905-790-9700) sized as per the schedule with the following features:

Cabinet shall be minimum 22 gauge G-90 galvanized steel with 4 inch primary air connection available as left or right hand or both ends for series connection. A locking cable actuated damper shall adjust the primary airflow for ease of balancing. Nozzle plenum shall have insulated sound baffles to reduce breakout noise. The nozzle bank shall have 6 different nozzle plate configurations to match primary air with induced air. Nozzles shall be manufactured of heat resistant polyethylene and designed for quiet laminar discharge to promote efficient induction.

Coils shall have one row of smooth, seamless copper tubes, manufactured to ASME specifications and rated to ARI Standard 410. Tubes are mechanically expanded into aluminum fin collars for permanent bond with standard sweat connections. Fins are aluminum, die formed plate type. Unit shall feature a drip pan in the event of condensate. Coils shall be suitable for use up to 350 psig at 150 degF.
