The ORANGE™ Locomotive Air Conditioner

We’ve upgraded our patented “ORANGE” Locomotive Air Conditioner (A/ C) to contend with current environmental and climate changes meeting HIGH AMBIENT conditions of up to 130 degrees.

ORA-2023 “Orange” Modifications

• Introduced “High Temp” motor controller to combat high ambient conditions.
• Switched to electronic thermostat for improved temperature control.
• Eliminated variable motor speed to shut down motor, enabling less heat generation in high ambient temperatures.
• Switched motor speed controller to relay operated.
• Regulated charge to eliminate overcharging in the field.
• Additional cooling fans and vents on compressor drive module for high ambient temperatures.

Key Benefits:

• Easy, lower-cost installation and operation
• Can be mounted in various vented locations on the locomotive
• Designed for low head clearance areas

The Orange AC integrates itself seamlessly into existing cabin interiors, without looking like a retrofit.

High Ambient Cooling

VRF (Variable Refrigerant Flow) technology works like the accelerator in a car, by matching the Out-Put to the Load. The compressor starts up smoothly and ramps up until it meets the demand. When the Thermostat is satisfied, it ramps down to turn off. This keeps the motor cooler in high ambient conditions.

Saves Energy

Running directly off the locomotive’s batteries, the Orange will save up to 30% in energy consumption while reducing power surges in the 72 VDC system.

No invertor means 32,000 BTU of cool reliability.
