We always recommend to sign a serviceagreement to ensure functionality and energy-efficiency. After a few months of operation, it is from an energy point of view an advantage to pick the machine and remove particles that are stuck. Bits of plastic bags and similar have the ability to get in the vortex. The aeration will still be working but likely with reduced efficiency. Many customers get in touch after a year or two and then have noticed the reduced oxygen diffusion through their continous samples.

Wash, review and adjustment is included in the basic agreement. We adapt the agreement according to your needs and requirements, number of visits per year and more etc.
To the right you will find an example of a regulatory list that we follow at each visit
