ElectroAir’s mobile APA-65 -series combined units consist of frequency converter units (AC rated output power up to 45 kVA) and rectifier units (DC continuous current up to 800A). These units are intended for the ground servicing of all aircraft types with a frequency of 400Hz and voltage 115/200 V and to power on-board electrical equipment and launch aircraft/ helicopters with a voltage of 28.5 VDC. APA-65 series is designed to eliminate CO2 emissions with its unique technical characteristics. Diesel hybrid unit and battery driven unit - unit can perform the complete service of aircraft at remote parking places with diesel engine / through batteries and it is also capable to operate from the 50/60Hz, 400V, 3 phase main power supply grid as any electrical GPU, without fuel consumption and with zero operating emissions. The range of different APA configurations with no emissions allow for safer, cleaner and more practical operational conditions for operators and personnel at the location. These units are very compact in size and weight.

[Cutting by water jet] Micro water jet cutting: The micro water jet enables a refined process to be carried out in precision cutting. This high-precision technology reduces the jet diameter by a factor of 5 and makes water jet cutting more precise by a factor of 10. The micro water jet achieves a cutting accuracy of +/- 0.01 mm and a positioning accuracy of ±0.005 mm. The proven advantages of the cold cutting process remain unchanged. In the pure water process, the cutting width was reduced to 0.2 mm in the abrasive process for hard materials such as nickel-based alloys and titanium. The new technology controls the cutting process and manipulates the cutting path depending on the contour and speed enabling a highly precise cut. Standard waterjet cutting: Water jet cutting is highly efficient and at the same time less severe than other cutting techniques. Low process forces and thermal loads prevent bending or melting. We can cut filigree delicate contours from practically all nickel alloys and titanium alloys. Using our standard process we can cut a range of shapes and dimensions according to customer requirements and drawings and achieve tolerances of +/- 0.1 mm or +/- 0.2 mm.

- Operates by an internal pipeline open/close mechanism controlled by a solenoid valve - Relief plug: prevents malfunction due to internal pressure expansion - Manual discharge available via manual handle when power is OFF - Outputs an abnormal signal if the reference pressure drops due to extinguishing agent leakage

Temperature Calibrated Pressure Sensors The Air Data Unit features very high accuracy absolute and differential pressure sensors. These are factory calibrated over a wide temperature range to further increase measurement accuracy and provide the best air data possible through varying conditions. Power Up Self-Calibration On top of factory temperature calibration, every time the air data unit powers up, it performs a self excitation calibration to adjust for small deviations of bias and scaling error. This allows the system to compensate for calibration aging and means that it never needs to be returned to the factory for recalibration. Reliability The Air Data Unit is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance. Its communication interface is optically isolated and the hardware is designed and tested to MIL spec.
