Whether it concerns telephone advice, remote support, or an on-site service visit, we think along with you, act quickly, and keep you informed.

Our service professionals are not only technically skilled, but also committed and solution-oriented. Together, we ensure reliable water treatment, now and in the future.

Service

VDH is available by phone for service requests and technical support. You can reach us at +31 (0)33 277 8600. In the event of an urgent malfunction outside officehours, you will be connected via a telephone menu.

Maintenance

We provide preventive maintenance for our salt electrolysis installations on demand or contract basis. With fixed maintenance packages (annual and three-yearly), we ensure your installation continues to operate reliably. This safeguards the continuity and extends the lifespan of your installation. With a maintenance contract, you are assured of fast service, lower costs, and preventive maintenance.
