GenesysNext

A new generation dryer

GenesysNext is a high performance, fully automatic, single-hopper drying system that optimizes the production process of PET preforms. Thus is true not only because it has been designed to reach advanced optimization 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.

It is for the first time that a system introduces 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 minimize and stabilize it on the set value. This is why it is possible to aim for maximum efficiency of the complete production process with scrap rate reduced to the minimum.

GenesysNext embodies the state of the art in drying systems for preform, creating a new standard. The production cost of a good preform has been reduced to a minimum level if one bears in mind the system’s main advantages: minimum waste of material in the form of scrap, lowest energy consumption and minimum manpower 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 in the direction of circular economy: an optional PureTech filtration system allows an advance filtration of the VOC that can be present in the process air. This is especially important in the case of recycled materials which can release low boiling point substances during the heating or injection process. PureTech filtration guarantees that every preform produced has a zero-contaminant content. This system also protects the desiccant towers, ensures consistent performance rates and a longer machine life.

Benefits

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

Genesys high efficiency drying

An innovative drying solution for a broad spectrum of applications

Genesys is a single-hopper, fully automatic – individual or central drying system. It can modify 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. Using only as much energy as absolutely required, this innovative drying system adjusts and controls optimal operating settings for the material to be dried. 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, promptly and independently adjusts and controls the air flow. The drying unit automatically modulates the airflow, resulting in optimum process operating conditions.

AIPC Technology

Automatic Injection Pressure Control

 

AIPC stands for Automatic Injection Pressure Control.
By means of this very innovative control of the residual moisture in the PET, any Piovan drying system of the GP series can be connected to the preform injection molding machine. AIPC is designed to read the injection pressure in real time and of to stabilize it to the desired value.

It is based on a new algorithm, specifically developed by Piovan RandD, which can constantly adjust airflow, temperature and dew-point of the process air, so that the injection pressure is kept at the highest possible level of constancy. This feature is particularly valuable nowadays since the new preform formats require thinner walls and therefore controlled conditions of moisture and injection pressure.

AIPC is a new invention, currently patent pending.

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
  • Highest energy efficiency of the whole process

ENERGY EFFICIENCY

Energy efficiency is a concept that in our part of the world became important towards the end of 2008 and the beginning of 2009, at the outset of the world economic crisis. Most business people had, until then, mostly declaratively considered power consumption as a significant element of the total cost analysis. In these considerations, the impact of energy efficiency on the environment pollution had hardly been tackled at all.

Neofyton was among the first companies in Serbia and the region to start actively demonstrating the importance of energy efficiency, both by cutting production costs and therefore increasing profit rates and building awareness of the resource shortage and broader ecological principles.

Energy savings through the use of Neofyton's machines

In comparison with our direct competitors in the field of plastics injection machines, and with the utilization of standard hydraulics with integrated so-called "smart" pumps, our machines consume as much as 50% less energy. The use of servo-hydraulics opens up the potential of savings as high as 70%. We have a very precise power consumption measuring device to prove this.

The company Engel was the first plastics injection machine manufacturer back in 2009, which introduced the power consumption page as a standard component of the control assembly – "Ecograph", where - next to the weight of each product (molded part) in every cycle - total hourly consumption is shown, as well as the specific power consumption per one kilogram of processed plastics (kWh/kg).

ENVIRONMENTAL PROTECTION

The equipment we represent contributes to ENVIRONMENT PROTECTION in several ways.
When it comes to ancillary equipment, above all water chillers by our supplier Eurochille, used for temperature control of both hydraulics and machine servo motors and molds (tools) in which finished products are made, the chiller systems we sell facilitate the use of a new cooling system based on the so-called "adiabatic effect".

In summer, the hydraulics and servo motors of the injection molding machines call for cooling with water at a maximum of 28°C. Using the so-called "free cooling" device with the "adiabatic effect", cooling of process water is performed without cooling compressors (which use freon as the heat exchanger). Heat exchange, i.e. cooling happens exclusively by the use of ventilators, which translates into six- to eightfold savings compared to traditional chillers that use freon-based compressors.

One of our customers has reduced the required cooling energy by 1.400.000 kWh per year, i.e. by about 70.000 EUR, using the "adiabatic" cooling devices. An additional benefit is the elimination of major pollution risks which might arise from emissions of freon into the atmosphere due to tube puncture or breakage.

A similar calculation can be applied to our Engel injection molding machines, as well as to the Piovan granulate dryers.

The Company Neofyton as PIOVAN’s partner

Neofyton is PIOVAN’s partner for the markets of Serbia, Bosnia and Herzegovina, Macedonia, Nigeria, and Cameroon. Piovan is a large international group founded in 1934 and has more than 70 years of experience and expertise in the production of ancillary equipment in the injection molding industry.
