GenesysNext

The new generation dryer

GenesysNext is the high performance, fully automatic, single-hopper drying system, that optimises the process for the production of PET preforms; not only because it has been designed to reach advanced optimisation of energy consumption thanks to a new configuration of the regeneration circuit and a new heating power recovery system, but also because it includes the PETformance tool.

This system introduces for the first time the concept of a direct connection between the drying and the injection processes, thanks to the GenesysNext capability to read the injection process in real time and to minimise and stabilise it on the set value. In this way the target is maximum efficiency of the complete production process with scrap rate reduced to a minimum level.

GenesysNext represents the state of the art in drying systems for preform, creating a new standard. The cost for good preform produced is now reduced to a minimum level considering the main advantages: minimum waste of material due to scrap, lowest energy consumption and minimum labour cost, since the system is fully automatic. Moisture Minder, the on-line instrument for the measurement of residual humidity in plastic chips, is now integrated in the GenesysNext control.

GenesysNext is also a step toward a circular economy: PureTech filtration system, available as an option, allows an advance filtration of the VOC system that can be present in the process air. This is especially required in the case of recycled materials that can release low boiling substances during the heating or injection process. PureTech filtration guarantees that every preform produced is contaminant-free. This system also protects the desiccant towers, ensures consistent performance rates rand a longer machine life.

Benefits

  • New user-friendly interface and powerful control
  • PETformance tool, to minimise scrap rate
  • PureTech filtration system for the processing of any kind of rPET
  • Integration of Moisture Minder data
  • Energy consumption optimization thanks to the new regeneration circuit
  • New control architecture for the control of a complete PET bay

Genesys high efficiency drying

The innovative drying solution for a broad range of applications

Genesys is a single-hopper, individual or central, fully automatic drying system. It can adapt and automatically control operating parameters based on ambient temperature, initial moisture level, type and quantity of polymer, the final moisture content of the polymer, and granule size. This innovative drying system adjusts and controls optimal operating settings for the material to be dried, using only the overall amount of energy strictly required. The settings are constantly compared with the data collected by the sensors installed on the system. A patented measuring unit, located in the air supply line, adjusts and controls the air flow instantaneously and independently. The airflow is modulated automatically by the drying unit, resulting in optimum process operating conditions.

AIPC Technology

Automatic Injection Pressure Control

 

AIPC stands for Automatic Injection Pressure Control.
It is a very innovative control of the residual moisture in the PET, by means of which any Piovan drying system of the GP series can be connected to the preform injection moulding machine. AIPC has the capability of reading the injection pressure in real time and of stabilizing it to the desired value.

The new algorithm specifically developed by Piovan R&D can constantly adjust airflow, temperature and dew-point of the process air, so that the injection pressure be kept at the highest possible level of constancy. This feature is particularly valuable today as the new preform formats require thinner walls and therefore controlled conditions of moisture and injection pressure.

AIPC is a patent pending new invention.

Benefits

  • Highest preform quality with consistent IV and AA values
  • Great reduction of scrap rate
  • Pressure accuracy +/- 2 bar
  • Fully synchronized system
  • Increase of the whole system productivity

ENERGY EFFICIENCY

Energetska efikasnost u industriji je pojam koji je na našim prostorima postao bitan krajem 2008. i početkom 2009. godine, sa početkom svetske ekonomske krize. Većina privrednika je, do tada, najčešće deklarativno razmatrala trošak struje, kao bitan element kompletnog pregleda troškova. Pritom uticaj energetske efikasnosti na zagađenje prirode gotovo uopšte nije bio razmatran.

Kompanija Neofyton je među prvima u Srbiji i regionu počela aktivno prezentovanje značaja energetske efikasnosti, kako zbog smanjenja troškova proizvodnje, pa samim tim i povećanja profitne stope, tako i zbog podizanja svesti o ograničenosti resursa i širim ekološkim principima.

Ušteda energije korišćenjem Neofyton mašina

U poređenju sa direktnim konkurentima u sferi mašina za brizganje plastike, a korišćenjem standardne hidraulike u koju su ugrađene tzv. “smart” pumpe, naše mašine troše i do 50% manje energije. Korišćenjem servo-hidraulike, postoji potencijal za uštedu do čak 70%. Posedujemo veoma precizan uređaj za merenje potrošnje električne energije, kojim se to i dokazuje.

Kompanija Engel je bila prvi proizvođač mašina za brizganje plastike, još 2009. godine, koji je u svoj upravljački sklop uveo, kao standardnu opciju, stranicu za prikaz potrošnje struje – “Ecograph”, gde se navođenjem težine za svaki proizvod (kalup), u svim ciklusima dobija podatak, kako o ukupnoj potrošnji struje po satu, tako i o specifičnoj potrošnji struje po kilogramu prerađene plastike (kWh/kg).

ENVIRONMENTAL PROTECTION

Oprema koju zastupamo doprinosi OČUVANJU ŽIVOTNE SREDINE na nekoliko načina.
Kada govorimo o pratećoj opremi, a pre svega o čilerima za hlađenje vode našeg dobavljača Eurochille, kojima se temperira kako hidraulika i servo motori u mašinama, tako i kalupi (alati) u kojima se i formiraju gotovi proizvodi, čilerski sistemi koje mi prodajemo omogućavaju novi koncept hlađenja korišćenjem tzv. “adijabatskog efekta”.

U letnjem periodu hidraulika i servo motori mašina za brizganje zahtevaju hlađenje vodom temperature do 28°C. Korišćenjem tzv. “free cooling” uređaja sa “adijabatskim efektom”, hlađenje procesne vode se odvija bez korišćenja rashladnih kompresora (koji koriste freone za izmenu toplote). Izmena toplote, tj. hlađenje se odvija isključivo korišćenjem ventilatora, čime se postiže ušteda od 6 do 8 puta u odnosu na klasične čilere koji koriste kompresore sa freonom.

Jedan od naših kupaca je, korišćenjem “adijabatskih” uređaja za hlađenje, umanjio potrebnu količinu električne energije za hlađenje, za 1.400.000 kWh/godišnje, tj. za oko 70.000 EUR. Dodatna prednost je odsustvo rizika, da usled pucanja cevi dođe do curenja freona u atmosferu i velikog zagađenja.

Slična računica se može primeniti na naše Engel mašine za brizganje plastike, kao i na Piovan sušare za sušanje granulata.
