Tank Wall Cleaning System (TWC)
The Ottevanger Tank Wall Cleaning system is a fully automatic solution for cleaning the inner walls of silos and storage tanks used for liquid products. As the tank is discharged, the unit treats the wall with a mould-inhibiting agent and rinses it using a spray nozzle. Cleaning takes place during normal emptying, so tanks can be refilled without the delays associated with manual cleaning or external contractors. The system helps producers meet hygiene requirements, reduces risk of mould formation and contamination, and keeps turnaround times short with a simple, functional design.
- Fully automatic wall-cleaning during discharge (no additional downtime)
- Float-guided treatment with mould inhibitor followed by spray-nozzle rinse
- Reduces mould formation and contamination on tank and silo walls
- Custom-produced to the specific dimensions of each vessel
- Can be supplied with an integrated control unit
Performance & Applications
Overview
Key benefits
Discover the key benefits of the TWC, designed to maintain clean tank walls while minimising idle time.
- Prevents idle time at refill — cleaning occurs while the liquid level drops
- Supports compliance with hygiene requirements by limiting mould growth
- Cuts dependence on external cleaning services and associated costs
- Short, predictable change-overs between batches or deliveries
- Simple, robust concept for reliable operation
Available executions
All machines can be customised. The TWC is built to the size and geometry of the silo or tank and can be delivered ready for installation and control integration.
- Custom dimensions for silos and storage tanks used for liquid products
- Supply including installation and, if required, a control unit
- Configured for use with mould-inhibiting agent (acid) and water rinse

FAQ
Cleaning is performed while the tank is being emptied; as the float sinks with the liquid level, the wall is briefly dosed with inhibitor and rinsed by a spray nozzle.
On silos and storage tanks that store and dose liquid products in feed and petfood production.
It avoids time-consuming, costly full-tank cleaning before each new load and reduces the risk of mould formation and contamination.
A custom-produced cleaning unit matched to the vessel; installation is available, and a control unit can be supplied if required.
Because the wall is cleaned during discharge, refilling can start immediately once the tank is empty, limiting idle time.
