General Information
Blower Coil General Information
Blower coil units are draw-thru air handlers for cooling load conditions of 400–3000 cfm. Units are
available in either horizontal (model BCHC) or vertical (model BCVC) configurations. Horizontal
units are typically ceiling suspended via threaded rods. Knockouts are provided in all four corners
to pass the rods through the unit. Horizontal units can also be floor mounted. Vertical units are
typically floor mounted. They have a side inlet for easy duct connection, and do not require a field
fabricated inlet plenum. Vertical units ship in two pieces and can be set up in either a pre-swirl or
counter-swirl configuration.
Basic unit components consist of a water coil, condensate drain pan, filter, duct collars, one fan
wheel, and motor with drive. See Figure 1. Drive components consist of sheaves, belt, and motor.
The coil, drain pan, and motor/drive assembly can easily be field-converted from right hand to left
hand configurations or vice versa.
Two, four, or six-row main coils are available for either hydronic cooling or heating. Three, four, or
six-row direct expansion (DX) coils are also available for cooling. An optional one, two, four, or six-
row heating coil is available factory-installed in either the preheat or reheat position. Also, a one-
row preheat steam is available.
All units have an internal flat filter frame for one or two-inch filters. An optional angle filter box (two
inch only), mixing box, bottom/top filter access box, or combination angle filter mixing box is
available.
In addition, all units are available with either a basic or deluxe piping package option that includes
a variety of control valve sizes in two or three-way configurations. The basic package consists of
