Out go the liquids

Q: What is your product?

The Heger Crocodile dewatering system available from Fercell Engineering separates liquids from solids.

Q: How does it work?

Raw material is introduced to the pressing chamber, which consists of the horizontally mounted rotating auger. Compaction takes place as the auger is turned, resulting in the liquid being forced out and flowing into the segmented screen at the base.

Q: Where would it be used?

The recycling sector in the separation of free-flowing components from packaging, such as the compression of PET bottles and metal cans, as well as the processing and drainage of food and utility waste before it enters an anaerobic digestion (AD) plant.

Q: How is it different?

It can be tailored to suit individual applications. All functions are electrically controlled.

Q: Across what industries has it been used?

Recycling and waste, beverage and food manufacturing, dairies and processors, breweries, paper, plastics, AD and sewage treatment plants.

Q: What are its benefits?

These include: single-button operator interface; control of all functions by a programmable logic controller; robust design; high efficiency with low power consumption; low operational noise levels, typically 60-70dBA; and variable dewatering pressure.

It has an automatic overload protection, and ancillary equipment includes drip pans, fill systems, output plus storage systems.

Standalone machines arrive pre-commissioned, requiring only electrical power connection for fast installation.

Q: Cost?

A mid-range output stand-alone installation might be less than £30,000. Most installations are bespoke so unit price varies.

Q Any savings?

Transportation savings are made following the removal of a material’s liquid content.

Q: What about maintenance?

Because the system has few moving parts, operational time between maintenance is exceptional. Installations can include a planned maintenance schedule.

Q: What is its life span?

This depends on the type of material being processed, volumes per hour and attention to a Heger- sanctioned maintenance programme.

Q: How is it future-proofed?

The modular nature of the Heger Crocodile enables upgrades and modifications to alternative applications.
