''IV stability through vacuum treatment''

''IV stability through vacuum treatment'' Despite varying moisture levels and different IV values in the input material, stable IV values are achieved through the patented pre-treatment method. This means, therefore, that input materials with higher material moisture levels can also be recycled.

''Melting under vacuum''

''Melting under vacuum'' The patented pre-treatment at raised temperature and in high vacuum before the extrusion process removes moisture and migration materials from the feedstock in a stable process environment. This prevents any hydrolytic and oxidative decomposition of the melt in the extruder.

''Low thermal stress''

''Low thermal stress'' The very short extruder screw without additional extruder degassing reduces the thermal stress on the material through minimized dwell time.

''Large area ultrafine melt filtration''

''Large area ultrafine melt filtration'' The filter systems have very large active filter surfaces. This enables filtration with up to 32μm fineness at low pressure. The result is highly clean pellets.

''~~Minimum production costs with ecoSAVE~~''

''Energy savings'' Vacurema technology feature ecoSAVE technology, which was developed especially to ensure high energy-efficiency levels. It is a complete design and process engineering package that includes a variety of energy-saving components and high-performance motors.

~~Electricity accounts for 38% of the costs of bottle-~~to-~~bottle recycling~~. ~~Thanks to integrated ecoSAVE technology, the lowest production costs~~ of ~~all systems on the market~~.

The now finished melt is then passed on to the downstream process for the

production of end products such as fibres, strapping, thermoforming sheet or amorphous or crystalline pellets.

With Vacurema Basic has become firmly established in the field of so-called inline production systems. PET secondary raw materials such as bottle flakes, ground amorphous skeleton waste, virgin material, edge trim and mixtures of them with virgin material are recycled directly to make end products such as FDA approved and ILSI compliant thermoforming sheet and even fibres and strapping. Besides these inline products Vacurema Basic is also used for the production of bottle-to-bottle compliant, ultra-fine filtered repellets.

Every Vacurema Basic system can be retrofitted if required to upgrade to a full ~~VACUREMA~~ Advanced or ~~VACUREMA~~ Prime high-end system.

Vacurema Advanced

Vacurema Prime

This

high-end PET extrusion system features two crystallisation dryers operating in batch mode. A compact, space-saving all-in-one solution which achieves IV increases and a remarkable cleaning effect.

As the user you are flexible at all times and can react quickly

to current market requirements: whether it‘s decontaminated, pre-dried and crystallised rPET flakes or high-quality, melt-filtered rPET pellets – products produced using VacuremA Prime technology fulfil the respective criteria of the FDA, EFSA and many major brand owners.

If IV values of > 0.9 dl/g or very high throughputs (> 2500kg/h)

are required, EREMA can offer you VACUREMA technology also in combination with an SSP solution from a global supplier.
