Airfield heating

HDU-43 ground support heater

The Contract for NGH expired in 2006.  The USAF, however, has an ongoing need for reliable heaters.  A new Contract was signed in 2009.  As a result of product development based on user and maintainer experience, some additional features were included in the design, perhaps most importantly a filtration system for the heated air. 

The nomenclature of this evolution model is HDU-43.

Main features:

  • NSN 4520-58-000-0441
  • 400,000 BTU / 115 kW
  • Fully autonomous
  • Meets U.S. mil standards
  • Multifuel operation
  • Operation time 11 hours @ +25°F ambient on High setting
