Operating a tank in the food, beverage, pharmaceutical, and cosmetics industries requires adherence to process, safety and hygiene standards. One of the process related challenges comes when adding or removing carbon dioxide, fermentation gases or nitrogen blanketing while ensuring optimal cleaning. The tank must also be protected from damage caused by overpressure or vacuum.

Tanktop assemblies, up to a certain diameter, can have the safety valve directly connected to the unit to protect against overpressure and the vacuum valve directly connected to protect against vacuum. This option, in many applications, eliminates the expense of a tank dome plate. In addition, optimal cleaning of the complete system and the additional safety fittings is assured.
