7 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 coils are light-duty air handlers, ranging from to tons nominal capacity. They are typically used in schools, hospitals, offices, stores, and similar applications. Trane Blower coils are UL listed to and Canadian safety standards for all: 115, 208, 230, 277, and 460 volt 60 Hz motors 220, 240, 380, and 415 volt 50 Hz motorsSingle Source ResponsibilityTrane is the single source of responsibility because we ship Blower coils from the factory as a total package. 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 3. Horizontal Blower coil10 BCX-PRC001H-ENFeatures and BenefitsPiping PackagesAll Blower coil air handlers are available with factory-built piping package options for field installation using field-supplied interconnecting piping.

8 Basic or deluxe piping package options are available with a variety of control valve options: Two- or three-way 1/2-in, 3/4-in, 1-in, or 1 1/4-in Two-position or modulatingThe basic piping package consists of two shut-off ball valves. The deluxe piping package has one shut-off 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 Models . These brushless DC motors incorporate the latest technology for optimized energy efficiency, acoustical abatement, maintenance free and extended motor life. Each motor comes with a VelociTach motor control board that allows for programmability, soft ramp-up, better airflow control, and serial communication. Trane units equipped with ECMs are significantly more efficient than permanent split capacitor (PSC) motors or belt-drive motors and enable single-zone VAV VAV control varies the fan speed as the zone cooling or heating load changes, and can result in lower operating costs and improved occupant comfort compared to constant-speed offers a broad array of control options, from a simple control interface (CSTI) to the Tracer controls are factory-mounted and tested to minimize field setup and improve reliability.

9 Factory provided low voltage wall mounted thermostat is wall-mounted zone sensors/thermostats require only low voltage control wiring from the device to the unit control box (no line voltage). The thermostat is factory configured based on selected control interface is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a disconnect switch (optional for units with electric heat). All end devices are wired to a low-voltage terminal block and are run-tested, so only a power connection and thermostat connection is needed to commission the unit. Changeover sensors and controls are provided when a change-over coil is selected. Tracer ControllersThe Tracer family of controllers ZN520 and UC400-B offers the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover service software for the ZN controllers, the UC400-B is serviced via Tracer TU.

10 This is the industry s first solution that is factory-mounted, wired, and programmed for infinite modulation of fan speed based on space loads, using the Tracer UC400-B. BCX-PRC001H-EN11 Features and BenefitsEnd DevicesOptional factory-mounted end devices such as a condensate float switch, freezestat, control valves, and actuators are available. Factory-installed and -wired electric heat features single-point power Trane Blower coil is available in either horizontal, vertical, or compact vertical 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. Compact vertical units are floor mounted and ship in one piece.
