• Variable Speed Drive Electric Motor: Reduces energy consumption and allows for gentle "ramp-in" start-up of mixing processes.

Supporting Systems:

• Standalone Thermal Control Unit (TCU): Manages and supplies thermal heating and cooling fluid for the heating jacket, particularly useful when plant services are not available.
• Operator Gantry and Staircase: Provides safe and easy access.
• Material Loading/Charging System: Efficient material handling.
• Standalone Hot Water Washing System: Available in CIP (Clean-In-Place), SIP (Sterilise-In-Place), and WIP (Wash-In-Place) configurations.

Safety & Regulatory Compliance:

• ATEX Rated (Explosion Proof) Electrics: Compliant with any required standard.
• Bespoke Guarding Systems: Including laser beam guarding for enhanced safety.
• Integral Discharge Barrier Isolator: Available with external access or 1/2 suit internal access options.
• Integral Charge Barrier Isolator: Provides options for external access or 1/2 suit internal access.
• CE and PED Compliance: Ensures compliance for European shipments.

Chemical Resistance Solutions:

• Alternate Materials of Construction: In addition to various grades of Stainless Steel (304, 316, and 416), ANFDs can be supplied in materials such as Alloy 20, Titanium, Alloy 22, and Alloy C276 (Hastelloy C).
• Chemical Resistant Coatings: StanCoat high chemical resistant coating provides a cost-effective solution for processing highly aggressive substances and is suitable for food-grade applications.

S2 Engineering’s Agitated Nutsche Filter Dryers (ANFDs) are designed to optimise production efficiency by integrating filtration and drying into a single, streamlined process. The ANFD’s multipurpose agitator is a unique feature that allows it to perform multiple operations through movement along both parallel and perpendicular axes to the shaft. Here are the key benefits of the S2 ANFD solution:

• Enhanced Production Efficiency:
  • Combines filtration and drying in one unit, reducing process time and increasing overall efficiency.
  • The slurry contents remain fluidised until most of the mother liquor is filtered, ensuring optimal processing.
• Improved Product Quality:
  • Maintains a uniform cake during filtration, preventing cracks that could disrupt vacuum operations and impact product quality.
  • Automated re-slurrying and washing of the cake within the vessel ensures thorough cleaning and high product purity.
• Versatile Operation:
  • The ANFD is capable of filtration, washing, re-slurrying, and drying—all fully automated—reducing capital and operating costs.
  • Ideal for multi-product, batch production plants, offering full operational versatility.
• Minimised Waste and Enhanced Safety:
  • Innovative equipment design minimises waste by efficiently discharging the cake with minimal residue.
  • The closed-loop system addresses environmental concerns by containing solvent evaporation and ensuring safe solvent recovery.
• Easy Maintenance and Optimised Chemical Compatibility:
  • Detachable, portable filter units simplify access for maintenance and replacement.
  • FEP elastomer sealing ensures optimal chemical compatibility, making it ideal for batch operations in a variety of industries.
• Reliable and Safe Design:
  • The ANFD features a bayonet design detachable filter unit, eliminating the need for manually intensive C clamp arrangements.
  • Integrated Barrier Isolator systems provide a controlled, operator-safe environment for direct heel recovery.
• Turnkey Solutions and Automation:
  • PLC-controlled automation enhances process reliability and efficiency.
  • S2 provides a turnkey solution, ensuring smooth integration of all technologies, leading to improved productivity.

The Agitated Nutsche Filter Dryer (ANFD) is a versatile filtration technique utilised in various industries, including:

• Pharmaceutical Production
• Textiles and Dye
• Paints, Varnish, and Surface Coatings
• Waste Water Treatment
