These compact, low-profile units can fit in small spaces and are floor or ceiling mounted. With a minimum of effort, they can be relocated within the building as needs units are light-duty air handlers, ranging from to tons nominal capacity. They are typically used in schools, hospitals, offices, stores, and similar applications. BCHD/BCVD units are UL listed to and Canadian safety standards for all 115, 208, 230, and 277 volt 60 hertz motors and 220 and 240 volt 50 hertz Source ResponsibilityTrane is the single source of responsibility because we ship BCHD/BCVD units from the factory as a total package.

10 Included in the package are factory-mounted coils, filters, controls, direct-drive motors, and duct collars. Also, factory-provided piping packages are an available option. Because we provide the total package, this helps reduce job site labor and installation 1. Horizontal Blower coilBCX-PRC001A-EN9 Features and BenefitsPiping PackagesAll Blower coil air handlers are available with factory-built piping package options for field installation using field-supplied interconnecting piping. Basic or deluxe piping package options are available with a variety of control valve options: Two- or three-way 1/2-inch, 1-inch, or 1-1/4-inch Two-position or modulatingThe basic piping package consists of two shutoff ball valves. The deluxe piping package has one shutoff ball valve, a strainer, and a circuit setter balancing valve. Basic or deluxe piping packages with a three-way control valve also include a balancing fitting on the bypass line. Energy Efficiency Trane s commitment to providing premium quality products has led to the exclusive use of Electronically Commutated Motors (ECM) in all Blower coil (BCHD/BCVD) Models .
