EKATO Sterile System

Functional
Description

VideoSpecial requirements on mechanical seals occur in the operation of sterile processes, such as food processing, inthe pharmaceutical industry and in biotechnology. Therefore EKATO offers a complete sterile system consisting ofa mechanical seal and a sterile installation. The EKATO sterile system is used when the vessel/process needs to besealed from any germs and microbes by the mechanical seal.

Advanced Process Solutions

The EKATO sterile system is an ideal solution for the process demand of a hot and completely sterile seal liquid
where germs and microbes cannot grow. On the other hand it serves the mechanical seal‘s demand of cool seal liquid
for seal face lubrication and cooling.

Step 1: Flow-through sterilization
Cleaning and sterilizing all parts with fresh steam
during standstill of the agitator

Step 2: System-filling
Filling the system with sterile condensate during
standstill of the agitator

Benefits

Step 3: Continuous loop-operation
Cyclical sterilization of the condensate by fresh steam
and additional cooling of the condensate by the heatexchanger during operation

A

Complete sterile system, mechanical seal and sterile installation out of one hand (less interfaces)
Self regulating system with very low energy consumption• Optimized mechanical seal design without gaps (ESD34S / ESD44S)• Sterile conditions in the storage vessel during operation: no germs and microbes growth• Constant circulation and continuous sterilization of the condensate• Overpressurized system due to steam pressure: no entry of external contaminations• Seal liquid condensate with ideal operating temperature: extended seal lifetime••

Operating parameters

Optional equipment

System pressure:3 – 5 bar (abs.)- Fill level meter for the storage vessel

System temperature:

130 – 150 °C- Tube bundle heat exchanger instead of plate heat exchanger (improved cleanability)

Seal liquid temperature:< 85 °C- Aseptic sterile connections (DIN 11864-1) instead of industrial fittings

EMechanical seal ESD34S / ESD44S for sterile applications
EKATO offers mechanical seals, specially designed for applications in sterile processes:• Double acting liquid lubricated mechanical seals• Ideal in combination with the EKATO sterile installation• Gap-free design and polished surfaces for easy cleaning and no product fouling (Ra ≤ 0,8 µm)• Due to slanting surfaces the product flows away from the seal
