       Honeywell (Booth No. 2600) said by the end of this year OEMs, including Bombardier and  Gulfstream, will have completed more than 400 conversions of the Honeywell 36-100 auxiliary power unit (APU) to the more quiet and reliable 36-150 APU. Honeywell claims the 36-150 is 50 percent more reliable than the Dash 100 and ten decibels quieter at the APU engine inlet. It is also less sensitive to surge, so the surge valve stays closed in more conditions. The conversion replaces the power section of the APU with a new ported shroud power section that increases airflow and reduces noise. The conversion includes no-cost enrollment in Honeywell’s maintenance service plan. More than 6,500 36-series APUs have been delivered.
