The EnSaLine B is a hygienic bottom-mounted agitator engineered to meet the strictest demands of sanitary processing. Where conventional agitators require tank entry for seal replacement or struggle with cleanability in tight geometries, the EnSaLine B addresses both challenges through deliberate design. The result is a unit that integrates seamlessly into hygienic tank systems while reducing the maintenance burden on operations teams.

How does the EnSaLine B cartridge seal system work?

The shaft seal is housed in a single replaceable cartridge that contains all seals and bearings. During maintenance, the shaft remains securely fixed inside the unit. There is no need for the technician to enter the tank. Seals and O-rings can be exchanged from the outside. This approach eliminates contamination risk during service and keeps downtime to a minimum. For facilities with strict hygiene protocols, this is a significant operational advantage.

What makes the EnSaLine B suitable for aseptic and sterile tank applications?

The internal design is fully flushable, with no mounting flange inside the tank and a hygienic seal housing that leaves no dead zones where product or cleaning media can accumulate. The seal housing supports SIP sterilisation at temperatures up to 150°C, and the flush media inlet accommodates temperatures up to 140°C. Operating temperature range spans -10°C to 95°C. These characteristics make the EnSaLine B directly applicable to sterile storage, UHT product tanks, and aseptic mixing duties where residual contamination is unacceptable.

EnSaFoil impellers for gentle product treatment

The EnSaLine B is equipped with EnSaFoil™ impellers available in two- or three-blade configurations. These impellers are designed to handle sensitive products gently — minimising shear and mechanical stress while maintaining homogeneity. This makes the agitator appropriate for applications such as drinking yoghurt, fruit mix tanks, flavoured milk, syrup solutions, powder dispersions, and fluids containing particles. The impeller geometry also supports heat transmission duties, circulating media in tanks fitted with dimple jackets for cooling or heating.

Does the EnSaLine B meet food-grade and pharmaceutical compliance standards?

The EnSaLine B meets EU and US standards including EHEDG, USDA, FDA, and 3-A Sanitary Standards. Product-wetted steel parts are manufactured from AISI 316L as standard. Surface finishes are specified by application type: Ra < 0.8 μm for hygienic food-grade use, Ra < 0.51 μm polished or Ra < 0.38 μm electro-polished for UltraPure pharmaceutical duty, and Ra < 3.2 μm for industrial use. Elastomer options include EPDM, FKM, and FFKM to match the chemical and thermal requirements of the process.

Condition monitoring and industrial connectivity

The EnSaLine B is prepared for industrial connectivity to support condition monitoring. An optional condition monitor accessory can be added to track the health of the agitator during operation. This capability supports predictive maintenance strategies, reducing the risk of unplanned downtime and extending service intervals. The unit is designed so that connectivity hardware can be integrated without modifying the core assembly.
