      • ECON Underwater Pelletizing System

      • EUP
        ECON is the leading provider of underwater pelletizing technology with thermally insulated die plates. The die plate is fixed on the heated carrier body. The thermal insulation ensures that the melt in the die holes will not "freeze". ECON pelletizers are not sensitive to fluctuations in output, thus making the pelletizing process extremely reliable and guaranteeing high operating efficiency.

        In addition, the compactly and clearly designed ECON water treatment and drying system is an effective solution for drying the pellets. The continuous filtration of process water ensures low maintenance requirements. Because the pellet dryer is easily accessible and free of dead spots, material or color changes can be done quickly. The complete pelletizing line can be easily adapted to different production conditions, thus increasing your flexibility.

        Generally, ECON's underwater pelletizers are offered in combination with the water treatment and drying system (EWT).
      • ECON Vibration Drying System

      • EVS
        Especially for materials with high filler content (e.g. with glass fibers or with mineral fillers), the vibration drying system is an excellent alternative to the standard centrifugal dryer. The gentle drying of the pellets ensures little wear and a low amount of fines. A residual humidity as low as 0.05 % can be reached.

        The vibration drying system consists of two or three sequentially arranged vibrating screens. The first stage serves for dewatering the pellets. In a dehydrator, the pellets are separated from the process water before they enter the screen. The process water is cleaned by an automatic band filter and recirculated to the process.

        In the second stage, the pellets undergo further drying. Electrical damping registers are installed under the vibrating screen to generate a warm stream of air through the screens.

        An additional stage can be installed to treat highly hydroscopic materials with even more stringent requirements for residual humidity.


        The ECON vibration drying system is suitable for throughputs up to 3,000 kg/hr.
      • Pellet Dryer, S+L

      • ECON's pellet dryers, S+L, can be combined with the ECON water treatment and drying system, but they are also suitable for stand-alone operation. These dryers are often used in the recycling industry to dry bulk or mill material or flakes. These centrifugal dryers are characterized by their compact design and sturdy construction. Depending on the temperature, size and structure of the material to be dried, residual humidities between 0.1 and 0.5 % can be attained.
        • compact design and sturdy construction
        • high throughput
        • gearless drive for maintenance-free operation

        The granules/water mixture is supplied to the drying chamber through the inlet case, which is incorporated as a sieve in the bottom. The granules are collected in the drying chamber by a rotor equipped with blades and are spirally conveyed upward through the sieve basket. The water is collected by bouncing and rolling the granules frequently on the sieve basket. The dried product leaves the dryer in the airflow through the tangentially arranged nozzle on the dryer top cover. The water outflow takes place through an outlet in the bottom of the housing or in the housing side.


        The pellet dryers are available with different input systems and/or several optional components (such as sound insulation), depending on your requirements. In addition, special gas or explosion proof and wear-protected designs are available.
      • ECON Air Pelletizing System, ELG

      • ELG
        The ECON air pelletizer was especially developed for processing wood and natural fiber compounds (such as WPC). Because water is used to cool and convey the pellets, processing wood-plastic compounds in an underwater pelletizing system requires a substantial amout of drying. Common drying methods are often unable to attain satisfactory levels of residual humidity.

        The air pelletizer was designed to use air to cool and convey the pellets and thus eliminate any need to dry the pellets. At the same time, the system benefits from the thermal insulation, resulting in a uniform cut and easy conveying of the pellets from the "cool" cutting surface, without generating chains or agglomerates.

        Among natural fiber compounds, the ECON air pelletizer is also well suited for processing PVC, which has a low inner specific heat, therefore requiring only minimal cooling.

        The air pelletizer can also be combined with the ECON underwater pelletizing system. With only a few modifications, one system can be used for both underwater and air pelletizing.

        The air pelletizing system consits of a pelletizing unit, a conveyor fan with noise reduction cover, piping and a cyclone and an electrical control system.

        The melt is directed to the pelletizing head with the die plate installed, and the emerging melt strands are pelletized.. The pellets are moved by an air stream that is produced by the conveyor fan. By the air stream the pellets are dried and are discharged through the cyclone.


        Depending on material properties, the ECON air pelletizer is available for throughputs up to 3,000 kg/hr.
      • Discontinuous Screen Changers

      • ESD
        With discontinuous screen changers, the screens are changed when the machine is stopped. The piston carrying the screen is moved out and the screen pack is switched.

        For melts with very low viscosity (e.g. PET or PA), the ESD has been further developed to the "ECON thermo sealer" (ETS). This model offers air cooling at the end of the pistons and is therefore leak-free, even with low viscosity materials.
        • approx. 65 % effective screen area for higher throughput
        • flow-optimized design of the melt channels
        • extremely low pressure build up protects material and screens
        • no dead spots for faster material changes


        To change the screens the machine has to be stopped. The piston carrying the screen is moved out hydraulically and the screen can be exchanged.
      • ECON Continuous Screen Changer

      • ESK
        The continuous double-piston screen changer allows screens to be switched out during operation.
        • all thermoplastic materials can be processed
        • optimal design of the melt flow way - short melt residence time
        • low pressure build up - to prevent thermal variations of the melt
        • no dead spots for fast changes of material and color
        • operational reliability and long durability

        The discontinuous screen changers are appropriate for throughputs from only a few kg/hr up to 2,500 kg/hr.
      • ECON Continuous Screen Changer with Backflush System

      • ESK B
        The continuous double-piston screen changers with backflush system provide major advantages with their fully automatic cleaning of the screens as soon as a defined maximum pressure is met.
        • all thermoplastic materials can be processed
        • optimal design of the melt flow way - short melt residence time
        • low pressure build up - to prevent thermal variations of the melt
        • no dead spots for fast changes of material or color
        • approx. 75 % effective screen area
        • operational reliability and long durability

        The piston in the backflush unit redirects the melt flow, so only one piston with screens is currently being used in the production process. The other screen pack is flushed backwards, so any contaminants with only minimal melt are removed from the screens through the backflush unit. Afterwards the process is repeated with the other screen pack.


        The continuous screen changers with backflush system are available for throughputs up to 3,750 kg/hr.

        • Energy Efficient

          Green, sustainable concepts are better for the environment, show a sense of responsibility to future generations and, honestly, are good for a company's image. But just as important, green solutions result in a lower energy balance and consequently lower production costs.

          ECON has many ideas to be green and save production costs. For example, our thermal insulation die plate saves energy twice. On the one hand, process water is hardly heated up and less cooling energy is required. On the other hand, less extrusion pressure is required, which means less energy consumption and lower costs.

          Saves energy

          The thermal insulated die plate transfers almost no energy to the process water.

          the process water is hardly heated
          less energy is required to cool the water

          Low extrusion pressure

          With the patented ECON technology, the extruder consumes less energy at the same level of output.

          lower extrusion pressure (up to 1/3 less pressure)
          less energy input required

          Conserve resources

          ECON's pyrolysis furnace works with an oil lubricated vacuum pump with an activated carbon filter.

          no water consumption
          no afterburner required
          no emissions
