Product Information.

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.
Pentair Südmo’s TankTop fitting offers a proven simple and reliable compact system that allows the addition and removal of gases and CIP cleaning fluid using one process connection. TankTop fittings, 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.
Correctly designing the process for the air cleaning combination depends on many factors that must be calculated for each tank or application. Information such as diameter, compressive strength and process
parameters must be clearly specified in advance. Customers can use the detailed form on page four to provide the needed information.

Challenge

  • Tank cleaning
  • Tank air ventilation
  • Tank protection

 

 

 

 

Application

Green: Filling of the tank –› gas exhaust
Yellow: Emptying of the tank –› gas feeding and breathing
Red: Cleaning of the tank –› feeding of cleaning liquids (CIP medias)

 

CIP tank Cleaning

Air Ventilation 

 

Security Against Over Pressure

 

 

 

 

 

Over pressure due to
• Filling
• Over filling
• Fermentation or chemical reaction
If gas exhaust is blocked

Could destroy the tank

Safety valves protect the tank against
over pressure.

Security Against Vacuum Pressure

 

Vacuum pressure due to
• Emptying
• Free drainage
• Chemical reaction
• Cooling down of the tank content
• Steam condensation
If gas exhaust is blocked

Could destroy the tank

Vacuum valves protect the tank against low pressure.

Tank Dome Plate

 

 

Customer advantages
• Flexible equipment
• Approved technology
• Cleanable and self draining
• Easy of assembly and maintenance
• According to all safety relevant regulations

 

 

 

Tank Dome Plate

 

Tank dome plate with:
• liftable vacuum valve and liftable safety valve
• dome plate prepared for measuring instruments such as level or pressure measurement
• sight class or other equipment

For optimal tank cleaning, various equipment can be used:
• Spray ball (diameter, flow rate and spraying angle adjusted to fit tank size)
• Rotation cleaner for larger tanks to reduce the flow rate of cleaning agents.
