AGI Pilot Plant Nutsche Filter PLUS

Pressurized filtration at pilot scale

AGI Pilot Plant Nutsche Filter PLUS is an indispensable system for kilo lab and pilot plant pressurized solid-liquid separation applications. The standard features offer all the functionality needed for successful filtration and a great user experience.

The jacketed vessel, large filtration surface area and manual stirring mechanism offer exceptional filtration performance. The wide impeller can be raised or lowered to smoothen or break the product cake surface. Systems of up to 30 L are supplied with a movable stand, protection shield and pressure safety features.

• Pressurized filtration up to 1.5 bar G
• All glass design for process visibility
• In-stand filter displacement for easy product access

AGI Pilot Plant Nutsche Filter PLUS is designed to accommodate the various steps involved in a filtration process. Most types of filtration processes can be performed in this system with a simplified work flow. 

• Pressurised filtration up to 1.5 bar G
• Jacketed and non-jacketed versions
• Accelerated cake drying as premium option
• Full jacket design for maximised thermal transfer
• Wide process temperature range -60°C to +200°C
• Easy access to filer using a lever mechanism
• Integrated pressure relief and shield for safety
• Support structure with castors for mobility
• Easy Cleaning and maintenance

Features

Sealed for up to 1.5 bar pressure usage

The vessel, filter, lid, and components are all designed to withstand pressures of up to 1.5 barG*. 

* for 30 L models with CE the max pressure is 1.1 barG

Easy product recovery

Safe and reliable system for product collection

Multipurpose stirrer blade

The filtration stirrer blade helps to mix the slurry during the mixing phase, and smoothens the product cake (in a clockwise rotation) so that the washing medium passes through it uniformly, ensuring thorough washing. After washing, the filtration stirrer blade helps to break apart (in a counter-clockwise rotation) the product cake for easy drying.

Effective filtration

The sintered filter (pore size of about 100 μm) supports the filter membrane. Double PTFE gaskets that sandwich the filter cloth lock everything into place. This setup, along with an O-ring, prevents leaks (including solids, liquids, and gases), and bypasses when the filter is closed. Filter membranes/cloths of up to 3 mm thickness can be used.

Accessories for performance and safety

Accessories include:

• Agitation handle for mixing, smoothing or breaking apart the product cake
• N₂ port for pressure
• Rupture disk (+1.8 bar G/+0.18 MPa cut off) with pressure gauge for safety
• PT 100 with holder for temperature monitoring
• Spray ball for cleaning the vessel
• Blind flange connection for use with any additional accessory of your choosing.

Clean with ease

For medium-sized nutsche filters, thorough cleaning after each use is essential to prevent chemical contamination between batches. It is particularly important to clean the flange and filtration parts.

The flange-grooves where the O-rings sit in standard vessels is prone to collect chemical residues after each process. Our Nutsche Filter vessel has a flat flange which makes it very easy to clean.

In the filtration part, the gaskets, O-ring and sintered filter are removable. The PTFE filter base has sharp and defined groves to allow easy access for cleaning. The flush valve is removable and has a run-off design where everything drains completely. These design features improve the way you work and clean the reactor, batch after batch.
