729308 — Condenser Repair & Overhaul

Component Overview

A condenser in the air cycle environmental control system extracts moisture from conditioned air by cooling it below its dew point so liquid water can be collected and removed, protecting downstream ducting and distribution from icing and corrosion. It is typically a compact plate-fin or tube core in which cold turbine-discharge air condenses moisture out of warmer process air. Because it handles condensing water under thermal cycling, its principal degradation modes are corrosion, internal and external leakage from cracked fins and brazed joints, fin damage, and fouling that reduces heat-transfer effectiveness and raises pressure drop. Inspection commonly reveals weeping seams, blocked passages, and corroded surfaces. Overhaul restores the core through cleaning, repair, brazing, and proof and leak testing to recover rated condensing performance and leak-tightness.

Aircraft Application

Part number 729308 (Condenser) is installed on the Twin Commander. QTC supports operators and MROs servicing this platform with certified repair and overhaul.

Our Repair Capability

QTC repairs and overhauls 729308 to the original manufacturer's specifications under our FAA and EASA Part 145 approvals. Our team — including former OEM heat transfer engineers — performs teardown, inspection, cleaning, component replacement, functional testing, and certification, returning a serviceable unit with the appropriate airworthiness release. We also develop repairs for rejected and beyond-economic-repair (BER) hardware.
