PLANET crossflow filters

Polymeric crossflow filtration from 10 to 200 m². Explore TEROP, PLANET semiautomatic and PLANET automatic configurations.

Choose your level
of automation.

TEROP and PLANET use crossflow filtration: liquid circulates along a polymer membrane at low pressure, while filtrate passes through and suspended solids remain in the circulating product.

All three versions use polypropylene capillary membranes with a nominal pore size of 0.2 µm, stainless steel membrane housings, Clamp connections and food-grade flanges. Periodic backwashing helps clear deposits from the capillaries during filtration.

TEROP.

10 m² · One model

A compact semiautomatic configuration drawing product directly from the customer’s tank.

  • Feed pump with automatic stop when no incoming liquid is detected.

  • Low-speed recirculation pump and scheduled automatic backwash.

  • Membrane differential-pressure monitoring with automatic stop at the set limit.

  • Backwash timing set inside the electrical cabinet.

  • Manual chemical dosing and washing, with a small vessel for preparing the cleaning solution.

PLANET semiautomatic.

20–30 m² · Two models

Touchscreen and PLC control, with an integrated product buffer tank and manually managed chemical washing.

  • Feed pump supplied from the onboard buffer tank, with no-liquid protection.

  • Low-speed recirculation pump for product circulation through the membranes.

  • Automatic backwash intervals configured on the touchscreen.

  • Differential-pressure monitoring and automatic stop when the set limit is exceeded.

  • Cleaning and neutralisation solutions dosed manually; washing remains under operator control.

PLANET automatic.

20–200 m² · Six models

PLC and touchscreen management of automatic filtration cycles, with inverter-controlled pumps and automatic cleaning-agent dosing.

  • Integrated buffer tank and variable-speed feed and recirculation pumps.

  • Automatic backwash and a rapid water-rinsing cycle.

  • Monitoring of membrane differential pressure, product temperature, incoming product and flow rate.

  • Automatic protective stops and pump regulation according to membrane differential pressure.

  • Clean Kit with piston dosing pump, three automatic valves and a hot/cold water mixing valve.

  • Programmable washing and neutralisation phases with automatic chemical dosing.

Technical options.

  • Isobaric configurations are available for TEROP and both PLANET versions.

  • The automatic PLANET 20 is prepared for expansion to 40 m².

  • Remote PLC access is available for PLANET automatic.

Before filtration.

Product should be enzymatically treated and free from pectins and glucans. Diatomaceous earth and bentonite must not be present.

Microfiltered water at 30–35 °C is recommended for rinsing and washing. The model tables specify a maximum working temperature of 50 °C.

800 litres for the washing circuit.

An optional 800-litre insulated hot-water buffer tank is available for PLANET semiautomatic and automatic configurations.

Hot-dip galvanised tank with painted outer casing, electric heaters, electrode and dial thermometer. The stainless steel support skid has adjustable feet and forklift lifting points. Includes a heater control panel, cartridge prefilter and additional hot- and cold-water outlets.
