NW-BEOH-C Passenger Car Overhead HVAC Unit

Blowers, Evaporator, and Overhead Heat package for railroad passenger cars

An Adobe Acrobat version of the printed brochure for this product is available in our PDF Files area.

The NW-BEOH series of HVAC parts are specifically designed to suit the comfort needs of railroad passenger cars. Our standard NW-BEOH is still available, but almost all of the units we have made recently are the compact version featured here. Customers generally prefer the increased resistance to static pressure in the ductwork, smaller size, and mounting flexibility offered by the NW-BEOH-C series described here. Features of this unit include:

• The unit enclosure in current generation units has been designed to allow for easy conversion to a rooftop-access unit instead of a car-interior access unit. Standard-order units are configured for access from the bottom inside the car, which is how the majority of car rebuilds require the evaporator section. However, customers may order units factory built to be accessed from the top, if the car is equipped with a roof access hatch.
  
  Our popular NW-BEOH-C air handler may be configured for access from a rooftop hatch, if requested at time of order.

• Just like our older NW-BEOH package, the unit is built in a two-compartment enclosure so that the unit enclosure breaks down into sections that can be moved through most very narrow passenger car hallways.
  
• Twin Blowers are welded aluminum, and have an impeller design that will continue to put out the required air volume even if the ducting has fairly high air flow resistance.

• Heater may be configured for up to 18 kW of electric heat, 480 volt or 240 volt three phase.

• As seen below, the unit may be configured to have the blower output to either the sides or end of the unit. Thus, this unit is far more flexible (in a somewhat smaller package!!) than our older model NW-BEOH package.

• Air Conditioning Evaporator Coil designed to meet the needs of most standard single-level passenger cars. For dome cars and other types of cars that require greater capacity, two units may be used with the unit pictured here providing enough capacity for the lower level of the car.

• Air Conditioning Coil made of rugged, widely spaced fins that will not clog or break as easily as refrigeration coils that are designed for stationary use.

• Our NW-100-CN condenser is sized to work extremely well with this unit.

• Welded stainless steel evaporator drip pan. The drip pan is quite a bit deeper than what is found on most evaporators designed for stationary use, in order to meet the requirements of service on a passenger car not sitting on level track.

• The evaporator drip pan has multiple possible connection points, in order to provide good condensate draining even when the car is sitting on uneven track.

• Unit enclosure is powder coated - a melted plastic finish that is superior to paint in this type of railroad application.

• Access Hatches are designed to make the equipment as easy to install and maintain as possible given the tight space of railroad passenger car HVAC systems.

• Dimensions: 56 inches wide overall at support flanges. 52 inches wide for enclosure only. 31 inches deep (dimension parallel to air flow). 15 inches tall means the unit can fit into even more compact overhead situations than our standard unit. For an illustration of these dimensions, see the NW-BEOH-C brochure available in our PDF Files area.
