Why VRF?
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 slowly for compressor cooling.
Compact, Dependable, Affordable
David Humann, President, INPS Group, said:Direct D/C system built for locomotives, not inverted like the rest. Fits all locomotives and climates.
Modular Design
Our design offers a unique Modular Design for easy operations during the Maintenance or Replacement of a component. Each component is heavy duty construction offering easier installation and lower labor cost to the installer.
Installation #1: Roof Mount – No Cutout
Our Compact Modular design can be easily mounted anywhere on the locomotive. The Roof Mount is most common and achieves a low clearance of only 10.5 inches to accommodate tunnel clearances or low bay doors.
