Individually configurable

Cleaning and protection from overpressure and vacuum

Tank Safety Systems

The tank safety system VARITOP® is a modular system based on standardized components. VARITOP® is used for tank cleaning, to protect tanks against inadmissible overpressure and vacuum and for controlled gassing and degassing. Every customer can select alternative functional components. In addition, the configuration can be designed largely individually. The result is a functional unit adapted to customer desires.



The securing of the tanks against overpressure happens via VARIVENT® safety valves and VARIVENT® vacuum valves against vacuum. 

Via only one central connection will gas and CIP paths switched. The CIP / gas management can be done by an automatic switchover module (no extra power supply required) or by a butterfly valve combination. The cleaning medium is guided through the CIP supply pipe to the cleaning lance or jet cleaner into the tank. If no cleaning process takes place, the gassing and degassing is ensured by a bypass on the cross piece and the switch module.

The tank safety system VARITOP® can be placed on a central connection or a tank plate. The interface is always the proven VARIVENT® flange connection on the cross piece.
