A rented tank is a critical resource for your production. When its condition deteriorates or maintenance is delayed, the consequences quickly show up in both costs and operational reliability.
In Finland, the tank owner is the party who initiates the maintenance need — either when product quality requires it or when the time for inspection or repair arrives. However, it is important for the user to be aware of maintenance needs and to work in cooperation with the owner to ensure smooth upkeep.
Maintenance for a rented tank without downtime
Maintenance of large industrial tanks is often seen as an unavoidable disruption. In reality, it can be carried out in a way that allows production to continue with minimal interruption.
The key is planning and the right method. When tank emptying and cleaning are carried out efficiently and without unnecessary idle time, downtime is kept to a minimum.
Method selection is particularly important here:
- The cleaning robot operates without scaffolding, completely eliminating the time spent on erecting and dismantling scaffolding
- The robot collects cleaning waste directly outside the tank, allowing the tank to return to service more quickly
- Properly timed maintenance prevents situations where the tank must be taken out of service unplanned
For the user of a rented tank, this means one thing: maintenance must not come as a surprise. It is advisable to agree on a clear maintenance schedule with the owner so that operations can be anticipated and carried out in a controlled manner.
Costs rise as tank condition deteriorates
Neglected tank cleaning is not just a technical problem. It is a financial risk.
When old, even hardened deposits accumulate on the tank walls, the cleaning work becomes more difficult and more expensive. The longer the work is postponed, the more time and resources it consumes.
For the user of a rented tank, this risk is concrete:
- A poorly maintained tank can result in a breach of contract with the landlord
- Unplanned downtime interrupts production at the worst possible moment
- Prolonged contamination can damage the tank surface and increase repair costs
- Regulatory requirements place clear obligations on industry regarding maintenance
Regular and properly executed tank emptying and cleaning is clearly more cost-effective than reacting after a problem has already occurred.
Robot cleaning and emptying – one complete service
We offer a complete service for tank emptying and cleaning, where everything needed comes from a single provider.
Emptying is carried out using a vacuum truck, a portable pump, or a combination of both. The tank contents are transferred to a location specified by the client or to appropriate further processing.
The cleaning method is always selected based on the needs of the site:
- Cleaning robot is the primary method for large tanks. It operates without scaffolding, moves along the wall sector by sector, and collects cleaning waste directly outside the tank. It is also effective against old, stubborn coatings.
- Tank washer is suitable for lighter cleaning tasks and is a fast option in the vertical direction.
- Manual pressure washing is used in situations where other methods are not suitable for the site.
The cleaning robot requires no scaffolding at any stage. It is assembled inside the tank and cleans systematically sector by sector. This significantly reduces the total duration of the project and minimizes workers’ exposure to substances contained in the tank.
In addition, we handle wall and ceiling washing, pipeline cleaning, and terminal area maintenance work during the same visit when needed.
