Agitators can be delivered approved for use in an ATEX environment with declaration of conformity.
Physical Data
3.1 Material certificates/FDA conformity statement according to 21 CFR177 on steel/elastomer parts in contact with media.
Impeller diameter range: ø250mm to ø1900mm.
Specific dimensions depend on configuration selected.
The EnSaLine S has an electrical drive motor that rotates the Agitator shaft, either directly or via a gearbox. The shaft rotates, turning the EnSaFoil impeller – a two or three-blade design engineered for maximum axial pumping efficiency. This creates strong, consistent flow throughout the tank with minimal shear, ensuring gentle product treatment and highly effective mixing and blending from top to bottom.
| Duties | Typical examples |
|---|---|
| Maintaining mixture homogeneity | Milk storage tanks, cream tanks, mixed product tanks, UHT, and product storage tanks |
| Mixing suspensions and solutions | Fluid and fluid mixing, drinking yoghurt and fruit mix tanks, flavoured milk mix tanks, and syrup mix tanks |
| Dispersing | Powder protein and oil mix tanks, micro salt and milk product mix tanks |
| Suspension | Fluids with particles, juice tanks, crystallising tanks, etc. |
| Heat transmission | Circulation of media in tank with dimple jacket (cooling or heating) |
| Flocculation | Wastewater treatment tanks |
| Operation benefits | Due to |
|---|---|
| Low energy consumption | The EnSaFoil impeller and wide range of drive units make it possible to design for up to 80% lower energy use and minimal operational costs |
| Gentle product treatment | High-efficiency impellers create strong axial flow with low shear, protecting product quality and yield |
| Low heat transfer to product | High-efficiency axial flow design minimises heat transfer, reducing the load on cooling systems |
| Hygienic benefits | Due to |
|---|---|
| Easy external cleaning | Stainless steel bearing frame with seal O-rings designed for wash-down |
| Connections inside the tank (risk zones) can be minimised | Bearing frame drives with drive shaft and special internal shaft connection – no flange coupling inside the tank |
| Good drip-off properties | No flat surfaces or grooves on internal parts |
| Easy CIP | No interior shadow sides between blades; smooth surfaces throughout |
| Maintenance benefits | Due to |
|---|---|
| All servicing (replacement of wearing parts such as shaft seals, bearings, etc.) can be done from outside the tank | Bearing frame drives with detachable shaft, dismountable from outside; all wear parts in a single replaceable cartridge. Throughout the process, the shaft remains securely fixed – there’s no need to dismantle it or enter the tank. |
| Easy dismantling | Spider-type coupling and stainless steel parts throughout |
| Fast service – under 30 minutes | Cartridge seal system and tailored service toolkit eliminate complexity |
| Tool-free access to drive unit | Easy-access design allows the drive unit to be reached and inspected without specialist tools – servicing can begin immediately |
Agitator Retrofit Boosts Dairy Energy Efficiency
Learn how retrofitting helped Molkerei Wiegert Dairy boost efficiency with up to 85% energy savings – and why they found the results hard to believe until they saw them.
Extend the performance of your Agitator
The EnSaLine S Side Mounted Agitator is designed for a wide range of tank mixing and blending duties across the Dairy, Food, Beverage, Personal Care, Biotechnology and Pharmaceutical industries.
The EnSaLine S is ideally suited to milk storage silos and large holding tanks, where side-mounting is standard practice. It keeps products homogeneous and consistent with gentle, efficient mixing.
The EnSaLine S provides reliable, low-shear mixing in pharmaceutical and biotechnology applications, meeting the strict hygiene and traceability requirements of regulated production environments.
The EnSaLine S is well suited to agitating in washbacks, pot ale tanks, and spirit tanks, keeping mixes homogeneous and consistent at all stages of the distilling process.
Yes – EnSaLine is designed with upgrades in mind. Provide the existing flange diameter and inTank can configure a tailored upgrade solution. The new design delivers better hygiene, lower energy consumption, and easier maintenance than the outgoing ALS range.
Yes. The EnSaLine S’s fully flushable design means cleaning-in-place can be performed during operation. Keeping the agitator running ensures the blades get full coverage from the cleaning heads, with no dead zones.
A full service – replacing seals and bearings – can be completed by one technician in under 30 minutes from outside the tank. All wear parts are housed in a single replaceable cartridge, so there’s no need to dismantle the drive unit or enter the vessel.
The Clariot VX sensor continuously monitors operating conditions – vibration, temperature and other parameters – to flag potential issues early, extend service intervals, and help avoid unplanned downtime.
The EnSaLine S is available with impeller diameters from ø250mm to ø1900mm and can be configured for atmospheric and pressurised tanks across a wide range of volumes and applications.
