The RET-EL POP UP PIT systems are factory-assembled complete units for insertion into a factory-built or created in-place concrete pit. The retractable, passable, electric media and distribution columns are installed flush with the floor below the apron or hall floor in separate shafts or tunnels within the parking position of the aircraft or maintenance and service hangar.

The RET-EL POP UP PIT systems are provided for the supply of aircraft and helicopters on the apron and in maintenance hangars.

These serve the underfloor supply of various aircraft and helicopters during flight preparation on the apron as well as maintenance and repair work in the halls.

On the apron and in the hangars they certainly create passable open areas and ensure the flexible and efficient supply of various media.

For all workplaces, they ensure direct and demand-oriented provision of energy, media and data.




Our underground systems are designed and produced for long life under extreme weather conditions and environmental influences.


The substantial advantages RET-EL POP-UP PITs compared to other PIT systems are:

    factory assambled completely install ready system for concrete pit-bunker
    individual, flexible equipping  
    introduce innovative technologies  
  modular konstruction design  
  automatic drive mechanic  
  "dad-man" switch  
  automatic end position control  
      automatic self-locking of the equipment cabin in every situation  
    quick & easy service and maintenance  
    comfortable and fast manhole for service and inspection purposes  
    built for long lifetime  

The special features RET-EL POP-UP with climate management system are:

     Protection systems:  
  rain, snow, dirt, sand and dust  
  surface water  
  reflux canal water  
  pressure water and flooding in end positions  
     Monitoring and control of a microclimate  
  intelligent automatic control of constant temperature in the pit-bunker
  intelligent automatic control of constanthumidity in the pit-bunker  
  antifreeze drainage pipes  
  rust, oxidation and mildew protection  

  LED warning light around the cover  
  display with current values, errors and system failures  
  remote monitoring / remote control  

  RET-EL Clima Plus System  
    pit-bunker waterproof in end positions  
    sand protection  
    maximum heat storage  

    low moisture formation  
  thermal insulation on the thermal bridges  

Our patented system RET-EL CLIMA PLUS with innovative autonomous drainage and microclimate system keeps the underground electrical operating room for a long time the effects of moisture and moisture in the ground, is equipped against the ingress of day and pressurized water and thus allows use, for example, frequency converter 400Hz sunk in the ground.


This Projekt have Innovation vaucher „B-Hightech“.

Operation is automatic by an electric drive with remote control or keys

Connection to sewage system not required! Savings when laying and connection to sewers.
