Anti-icing screen for helicopter engine air inlet. Specific Application: Shower Heating system for VIP business Jet 1 / 9

2 Technical Application of Grey water drain mast To save weight, the grey water from the washbasins is ejected to the outside of the plane. Function of the configuration, most planes are equipped with two drain masts, one at the front and one at the rear where the washbasins are. Drains are fixed at the bottom of the fuselage exposed to the outside air. The major risk with a drain mast is the production of ice at the tip and risking a potential impact with the fuselage or it getting sucked into the engines. 2 / 9

3 Technical Description of Drain Mast Anti-Icing In accordance with the specification, the drain is equipped with one or two water pipes. The shell is made using the resin-moulded method. For optimal efficiency of the anti-icing system, THERMOCOAX technology warms up the water pipes instead of the shell. Heating cable technology available: Self-regulated cable Or fixed power cable coupled with switches Inconel or nickel sheath cable Ø 5 up to 3mm Power supply 28 or 115Vac 400hz Dissipated power from 20 to 250 Watts Pipe Temperature up to >40 C at -55 C environmental conditions Each heating cable is produced with cold ends. The cable is then wrapped onto the tube. 3 / 9

4 The cable is flexible enough to increase the volume of cable and get more heat for areas exposed to coldest conditions. Cable is brazed on the tube for: Conduction pipe/heater for more thermal efficiency Robustness Reliability Longevity Production repeatability 4 / 9

6 Acceptance Test Criteria of Drain Masts: Dimensional Weight Line resistance Insulated resistance under 500Vcc Dielectric 1mn 1500Vac Test for Qualification Program of Drain Mast THERMOCOAX conducts the qualification test program in accordance with our customers' specifications. Our engineers write the QTP for customer approval prior to running the tests. Most of the tests (thermal, humidity, electrical etc.) on the drain mast are performed in THERMOCOAX s test lab facilities. These require heavy equipment (vibration, acceleration, impact etc.) and are sub-contracted to external laboratories or provided by our customers with the complete water system. -Typical Qualification Test Schedule for Drain Mast Vibration Acceleration Impact & Crash Safety Vibration 6 / 9
