Design of  bowser

1. Tank 

  • It is of  the cross section oval shape, uncalibrated, single-compartment made from the corrosion resistant stainless steel;
  • There are  the volume indicator of filling  and the  limit level alarm of  filling;
  • In the bottom part there are  the channel and the  drain system  with the ball cock Ду40 for the fuel total discharge  and ball cock Ду40 for the sampling 


2. Chassis

  • Chassis of truck  МАЗ-437043 (4×2) Euro-3 specially refitted for the transportation  of the dangerous cargoes  (protection of the fuel tank, dumper with spark suppressor is located in advance and on right, beacon of the yellow color is installed, fire extinguisher, box for the  adsorbed materials, identification nameplate);
  • Protecting wings with splash guards are installed over the wheels;
  • Set of SPTA(set of spare parts, tools and accessories, including the spare wheel;
  • Remote control for the motor revolutions (at the parking) from the fueling station;
  • Upon Customer’ request independent starting heater is installed for the heating of cooling liquid at the low temperatures of the ambient air, for the maintenance of the heating rate of the motor and cab at the parking place at the disconnected motor and at the running of the motor car.


3. Filling system

  • Fueling equipment includes the necessary devices and instruments for the safety filling of the aircrafts;
  • In case of the emergency onset the operator has the possibility immediately to stop the filling process by means of the pressing the emergency stop button (red color) of the motor operation. 
  • Fuel pipelines and on-off valves (ball cocks  Ду10, Ду15, Ду20, Ду40, Ду65) are made from the stainless steel, the tightness  as per  GOST  9544-93, class А;
  • Position of the ball cock handle is unique for the operator;
  • Maximum pressure of the fuel system pump is – 4,8 kgf/cm2.


4. Pump

  • Self-priming centrifugal pump СЦЛ-20-24Г is intended for the aviation fuels and ensures the performance of the ATZ operation stated parameters;  
  • Driving of the fuel transfer pump from the chassis motor through the power take off box and cardan drive.


5. Filter-water segregator

  • Filter – water segregator ФВГк-56.516/02 (production of research and production association «Agregat», Chekhov, Moscow region) with the spare set of the filter components;
  • The filter- water segregator housing made from the corrosion resistant stainless steel;
  • Sampling before the filter, after the filter and sediment bowl.


6. Flow meter -counter

  • Fuel counter ППВ-100-1,6СуК, the accuracy class of 0,25
    (OJSC «Prompribor», Livny, Orel region) or fuel counter  МКА 800 (firm «Alfons Haar», Germany);
  • Presence of the current GosStandart Certificate of  Russia about approval of the measuring means type.


7. Filling hose

  • Filling hose ОРТ-50 with length of 15 meters with nozzle of the bottom filling  and the pressure regulator  60427 CDEF46K+WL 29229/25of firm “Каrter”. The distributing gun  РП-40Г with an  extension bar are included in the set of SPTA;
  • There is an integrity testing device of the ОРТ-50 fuelling hose strings and grounding cables;
  • Filling hose is located on the hose drum, the winding of the hose is performed mechanically with application of the pneumatic motor.


8. Tank loading limitation system:

When reaching the fuel limit level in the tank:

  • Filling valve is closed;
  • Extraneous pump  (in the filling station) is disconnected;
  • Light and sound signals are supplied.


9. Grounding system and  fire-extinguishing means

  • Two coils with grounding cables are installed on the bowzer, one coil  at the end of cable  has the “alligator” clamp for aligning of the potential between the ATZ and aircraft, other coil  with the pin at the end of cable  is used for the grounding . The winding of the cables is mechanized.
  • Bowzer has the grounding circuit continuously contacting with ground;
  • Bowzer is completed with fire-extinguishing means: fire blanket, two  dry-chemical type fire extinguishers  ОП-6 and one carbon dioxide type fire extinguisher  ОУ-3 (located in the cab of chassis truck)


10.Painting of the external surface of ATZ is performed with enamel  of firm  «Khempel» under the color diagram as per GOST 52396-2005 with indication of the aviation enterprise name, ensign plate, garage number timely  provided by Customer on the left and right sides.
