Features: Built for Industrial Toughness

Screw and filter housing made of duplex stainless steel (2205), with a corrosion resistance 5x higher than 316 stainless steel—ideal for pH 2-13 wastewater.
Tungsten carbide-coated feed hopper resists abrasion from crystalline solids in bioreactor sludge.

Processes 12 m³/h of sludge, achieving 35-40% solids content even for sticky biochemical waste (tested on penicillin production sludge).
Variable-speed drive (0-20 RPM) lets you adjust pressure for different viscosities—from thin fermentation broth to thick polymer sludge.
Large 2m-long filter screen (0.5mm pores) with anti-clogging surface treatment, reducing screen replacements by 50% versus standard presses.

PLC-based control panel with remote monitoring via Ethernet—track solids content, motor torque, and water flow from your office.
Automatic overload protection: Stops the screw and sounds an alarm if solids buildup exceeds safe levels, preventing motor damage.

Pharmaceutical Plants: Handles sludges from API production, fermentation tanks, and wastewater with residual solvents.

Biotech Facilities: Dewaters cell culture waste, plasmid DNA production sludge, and other high-value biological residues.

Chemical Processing: Effective for polymer sludge, catalyst residues, and sludges with heavy metal chelates.

Industry Expertise: The only press certified for biochemical wastewater by the International Society of Pharmaceutical Engineering (ISPE).

Downtime Reduction: Advanced materials and self-monitoring features cut maintenance time by 40% compared to generic industrial presses.

Custom Solutions: We offer optional heated jackets for low-temperature environments and explosion-proof motors for hazardous zones.
