Double-walled underground tanks for flammable and non-flammable materials

The double-walled stainless steel underground tanks meet all the environmental requirements set by European countries for liquids with harmful effects on groundwater. The two stable and resilient steel walls, insulated externally with polyurethane, together with a space monitoring system on both walls, provide a reliable and environmentally friendly fuel storage system.

UNDERGROUND STORAGE - SECURITY AND SPACE SAVING.

The advantage of underground storage is the use of a large storage capacity (up to 120,000l).

Outer surface:

Hardened to Sa 2.5 according to PN-ISO 8501-1 and protected against corrosion by the ENDOPREN polyurethane coating, which is puncture resistant to 10 kV/14 kV.

Purpose:

For liquid flammable or non-flammable, environmentally hazardous or non-hazardous substances (fuels, fuel oil, diesel, petrol, gas, etc.) with a density not exceeding 1,1 kg/dm3 according to EN 12285, Class A and 1,9 kg/dm3 according to EN 12285, Class B and DIN 6608.

The container is supplied as standard:

Depending on the customer's requirements, the tank can be equipped with:

filling pipe with overflow protection valve and hydraulic lock; fuel pumps, suction pipes for pumping fuel from the tank; a water outlet pipe to allow pumping water out of the bottom of the tank; a measuring pipe, which allows the quantity of fuel in the tank to be measured using a measuring rod; a manual measuring connection; an automatic measuring connector (for the measuring probe); an air outlet connection;

Spare connector; vapour return connection for VRS. Optional extras:

Class C retractable covers 250 kN and D 400 kN; manholes on the container; central drain manholes; galvanised anchor strips; leak monitoring systems GOK, Afriso, SGB; Fuel quantity monitoring systems OPW or others. Technical data for tanks:
