The underground systems are modern and practical solution for invisible, space-saving and efficient power distribution and power supply. The underfloor systems have found their use in many different places from municipalities to airports.

The retractable supply posts, market place supply systems, underground power distributor and PIT systems provide flexible space and room supply of electricity, data, water, compressed air, wastewater and other media. The underfloor distributor provide an aesthetic urban design in which the street distribution disappear from sight.


It would be fine if the environmental conditions were not so extremely aggressive. The installed in the ground box, is made of metal, plastic or concrete, is permanently exposed to the following environmental factors or risks such as:


S   surface water flooding  
 A   ground water flooding  
 F   flood / water pressure  
 E   flooding due to reflux of canal water  
    medium to long-term water-storage in the bunker
 A   permanent very high moisture and humidity in the bunker
 G     rain, snow  
 A     soil moisture  
 I   daily temperature fluctuations  
 N     high condensation inside the shaft  
S     extreme moisture buildup under the cover  
T     Frost  
    missing ventilation / air circulation  


This bunker is considered highly hazardous area and ruquires the numerous measures in order to safely set up the electrical equipment. The standard installation of equipment with IP 65-IP68 protection doesn´t provide the  necessary protection of electrical divices from conditions described above.


The innovative unique underfloor systems RET-EL developed considering all dangers and risks for long and safe useful life.

Patented systems RET EL Climate are equipped with an autonomous "intelligent" microclimate system. This system creates a durable and safe placement and trouble-free function all electrical and electronic equipment under the ground. The "intelligent" microclimate control system provides reliable protection against surface water, ground water, moisture, humidity, frost and floods.


The advantages of using RET EL underfloor systems:      

Schacht Wasser

  permanent standby modus
  modernize urban infrastructure      
  place higher functionality      

Schacht Warm

  protection of the system during flood      
  efficient and Secure Media Supply      
  higher safety of pedestrians and other road users      

Schacht Moisture

  consumption control      
  reliable, sustainable protection of the electrical room      
  high protection against vandalism
