RET EVU Unterflurverteiler


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.

As underfloor units 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:

Intelligent automatic control and regulation of constant temperature and humidity

protected about water or pressure water and flooding in end positions

safe surface drainage without connect to sewer

permanent temperature monitoring and temperature control in the PIT shaft

flexible equipping

heat insulation of thermal bridges

antifreeze drainage pipes

comfortable and fast manhole for service and inspection purposes

automatic self-locking of the equipment cabin in every situation


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.

Our patented system RET-EL KLIMA 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.

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


Protection of the shaft inside against:

rain, snow, dirt, sand and dust

surface water


reflux canal water

high water


rodents, insects and vermin
