Operation & Maintenance

Preventative Maintenance

The extensive network of systems erected by ASE are supported by trained teams of technicians, that visit plants on a regular basis based on the requirements of individually established maintenance support agreements.

Chemical Dosing Equipment

ASE introduced the Grundfos range of chemical dosing and chlorination equipment in Namibia in 1993, with most of the Namibian water works being equipped with this range of dosing pumps and chlorinators.
The supply, service and maintenance of these systems are supported by trained teams of technicians available to do on-site maintenance and repair work, ensuring minimum downtime of the equipment.
