DOPA 1 system

DOPA - realization a second inner coat in one-wall tank with the system of permanent monitoring of tightness of second inner mantles of the tanks through vacuum (EN 13 160 class 1).

Company IDOPS creates the second inner mantle in one-wall steel or concrete tanks with the system DOPA. IDOPS is an exclusive representative of the company ADISA, Switzerland, owner of DOPA, for Czech and Slovak republic. We are specialized for the supplies of second inner mantles of the tanks made from composite materials and with the system of permanent monitoring of tightness of the tank through vacuum. We create also the second bottom of one-wall tanks with the system DOPA. We create a second inner mantle or bottom in new, existing underground, and also aboveground tanks.

A second inner mantle created with DOPA provides after assembly strong resistance against stored liquids. A surface of inner mantle of original tank is protected against corrosion. Second inner mantle from composite materials is allways made directly at customer. A second inner mantle has not shape restrictions, we make it in various shaped tanks. A rapidity of works of application is another advantage of DOPA. A whole technology of creation of second mantle on the wall, and bottom of the tank does not need a new additional opening into the tank. All assembly operations by the installing of the system are done through the existing openings of the tank.

IDOPS has made untill today with the system DOPA tanks in total volume more than 200.000 m3, what means the area of the second mantle with permanent monitoring of tightness about 60.000 m2.

A second inner mantle provides for tank operator a highest posiible safety for storing of crude oil products, or chemicals. Owner of the tank equipped with the system DOPA has a permanent overlook about the tightness of the inner mantle of tank. It does not come to uncontrollable escape of stored chemicals caused by leakage of inner mantle and pollution of underground water.

Application of the second inner mantle guarantees a high purity of stored medium without contamination of corrosion remains. A system DOPA has long-term tested declared properties proved by operation, it is completely resistant against new fuels, additives and biofuels ang this is another advantage compared with competitive systems. A system is proved by more than 30 years operation.

Tanks with composite lining for storage of dangerous substances equipped with the system of permanent detection of mantle tightness through vacuum ( system of leakage control according to EN 13 160- Class 1) contribute actively to the protection of environment and underground water. Thanks to built of high corrosion protection is ensured a long operating life at low operating costs.
