Moving through specially designed nozzles, steam energy is converted and has a heating effect on the oil sludge.

- No personnel inside the tank until its total degassing
- Technology is applicable for cleaning of damaged tanks and tanks in critical condition
- Technology is applicable to any tank size, type and design
Simultaneously with the washing process which saves energy costs. Steaming allows to completely neutralize all pyrophoric compounds

- No chemicals or crude oil used
- Technology is applicable at potentially hazardous facilities
- Complete neutralization of pyrophoric compounds
Into three fractions: oil, water, sediments. Recovery of up to 97% of oil organic part. Net profit instead of paying costs for waste disposal.

- No weather or seasonal restrictions
- Maintaining the integrity of the tank steel structures
- Simultaneous tank cleaning and oil recovery
The pumped-out oil almost does not contain any sediments, as a result, there is no technological process breakdown and pipeline wear. The water condensed during steaming is safe and is drained into the industrial sewage.

- Minimum volume of sediment for disposal
- No weather or seasonal restrictions
- No harmful emissions to the atmosphere
