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.
To receive a quotation for the heater and for after sales services and spare parts please contact NGH Retail in Valparaiso, IN USA (see Contact information or nghretail.com).
