After Sales

From Training To Remote Service: The Additional Services By Stilmas


Trained operators have a key role for a constant and smooth operation. Stilmas is ready to provide dedicated training sessions in addition to the standard one during start up activities, both on the Customer’s side or in Stilmas’ premises. Training sessions can be organized even for Customers’ supervisors as well as validation technicians.


In most cases, the obsolescence of an equipment is related to instrumental and electronic parts and components, like control systems. Stilmas Service dpt. is able to provide the full overhauling of existing systems, including a relevant change control.

Technical Assistance

Technical assistance can range from a simple telephonic support to a direct and fast intervention on site. In order to grant the most efficient reactivity, Stilmas has established a number of regional and local after sales services, to better fit any customers’ needs.

Our activities also include the fine tuning of the plant, so to reach the highest performances.

Preventive Maintenance

Preventive maintenance is the best way to grant the continuous operation of water systems.
