Alfa Laval EnSaLine S hygienic agitator

Alfa Laval EnSaLine S hygienic agitator

The Alfa Laval EnSaLine S hygienic side-mounted agitator delivers reliable, energy-efficient mixing and agitation in both atmospheric and pressurised tanks. Built for industries where product purity and process reliability are non-negotiable, it raises the standard for agitator performance across demanding hygienic environments.

At the heart of the EnSaLine S is a fully flushable design with no internal mounting flange, combined with a hygienic seal housing that supports superior cleanability. All seals and bearings are housed in a single replaceable cartridge, enabling one technician to complete service in under 30 minutes — from outside the tank, without tools. This approach minimises downtime and eliminates the need to enter the tank during maintenance.

EnSaLine S is prepared for wireless condition monitoring, giving operators real-time insight into agitator health. It meets EHEDG, USDA, FDA and 3-A Sanitary Standards, making it a confident choice for sterile and aseptic applications in dairy, food and beverage, biotechnology, and pharmaceutical production.

The EnSaLine S is a hygienic side-mounted agitator designed to handle a wide range of tank mixing and agitation duties across process industries. Its compact, side-entry configuration allows installation on both atmospheric and pressurised tanks without compromising cleanability or structural integrity. The unit is engineered to maximise yield while keeping operating costs low — directly reducing energy consumption and maintenance time from day one.

How does the EnSaLine S achieve superior cleanability?

Inside the tank, the EnSaLine S presents a fully flushable geometry with no mounting flange on the wetted side. The hygienic seal housing eliminates dead zones where product or cleaning media could accumulate. This design makes the agitator well suited for sterile and aseptic applications, where any residual contamination risk is unacceptable. The unit complies with EHEDG, USDA, FDA and 3-A Sanitary Standards — certifications that matter to quality managers and regulatory teams in pharmaceutical production, dairy processing, and food processing alike.

What makes the EnSaLine S easy to maintain?

All seals, O-rings, and bearings are consolidated into one replaceable cartridge. During maintenance, the shaft remains securely fixed in position, so there is no risk of it dropping into the tank. A single technician can complete a full service in under 30 minutes, accessing everything from outside the tank without specialised tools. This design directly reduces unplanned downtime and lowers the total cost of ownership. Spare cartridge units and complete service kits are available to keep critical lines running.

EnSaFoil™ impellers for gentle product treatment

The EnSaLine S uses EnSaFoil™ impellers available with two or three blades. These impellers are engineered to deliver effective mixing — whether keeping media homogeneous, blending liquids, dispersing powders and oils, or suspending particles — while treating the product gently. This is especially relevant for shear-sensitive products such as drinking yoghurt, flavoured milk mixes, fruit blends, and syrup solutions, where excessive agitation can degrade texture or functionality.

Which tank mixing duties does the EnSaLine S cover?

The agitator is designed for a broad range of duties. It keeps stored media homogeneous in milk storage tanks, cream tanks, UHT tanks, and general product storage tanks. It handles fluid mixing in yoghurt, fruit mix, flavoured milk, and syrup tanks. It disperses powder proteins and oil mixes, as well as micro salt and milk product mixes. It also manages suspension of fluids with particles — including juice tanks and crystallising tanks — and supports heat transmission by circulating media in tanks fitted with a dimple jacket for cooling or heating.

Motor efficiency and industrial connectivity

The EnSaLine S is fitted with a high-efficiency premium gearbox and supports IE3 (standard) or IE4 motor efficiency classes. The ingress protection rating is IP55 as standard, with IP66 available. The unit is prepared for industrial connectivity, enabling wireless condition monitoring as an accessory. This makes it compatible with modern process environments where predictive maintenance and remote diagnostics are part of normal operations. All motor voltages and frequencies are available to match local supply requirements.
