Maintenance

No regular maintenance is required if the EL-FLOW® Classic is operated properly, with clean media, compatible with the

wetted materials, avoiding pressure and thermal shocks and vibrations. Units may be purged with a clean, dry and inert gas.

In case of severe contamination, cleaning the inside of the device may be required. After cleaning, recalibration of the

instrument is recommended.

Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is

used in. Therefore, servicing must be performed by trained and qualified personnel. Contact your local Bronkhorst

representative for information about cleaning and calibration. Bronkhorst has a trained staff available.
