Innovative systems for drying plastics

PLUG & DRY - material drying all-in-one-solution

In the field of auxiliary equipment, Eisbär manufactures systems to improve quality and productivity for the plastics industry, specializing in products to avoid condensation on the moulds, drying of plastic resin and the process of PET flakes.

Performance is in the air

The heart of the continuous material drying process is the slowly rotating adsorption wheel with its multitude of honeycombed, axially aligned tunnels. The inner walls of the tunnels are lined with a desiccant. As it flows through the lower half of the adsorption wheel, the process air is dehumidified by the dessiccant. During the next quarter-turn, hot regeneration air flows through the tunnel and in turn dehumidifies the desiccant In the next quarter-turn, the adsoprtion wheel is cooled to operating temperature and is then able to dehumidify process air again. 


Simple user interface

To operate the system there is a touch panel with graphics capabilites (fig. 2). On a series of monitor pages, the operator can call up operating parameters in different languages, such as for instance processair dew point, filling level in the drying hopper, delivery capacities, valve status or process temperatures. On this monitor pages you can also adjust process set points and alarm settings. After selecting with the cursor, the monitor displays the type of error, the time at which it occurred and a fault signal number. The dryer can also communicate over Ethernet (Profibus or ISO on TCP/IP) to a MES (Manufacturing Execution System). 
Service friendly and  highly reliable

The two radial fans with direct drive and the low speed adsorption wheel are the only moving parts of the system. This also reduces the costs of servicing the plant. There are only filterts to be cleaned as required.

Advantages of the Plug & Dry system:

  • All-in-one-system
  • Screw on, plug in and start  
  • Power connection and material supply line is all you need!
  • Compact design.
  • Low space requirement.
  • No refrigerating technology (environmental protection).
  • No cooling water required (system without cooler).
  • Closed circuit for process air - continuous and rapid drying process.
  • No limits regarding ambient conditions and dew point.
  • Clearly structured visualisation  of all operational data for efficient control.
  • Compatible for communication over Ethernet to a MES.
  • Lowest energy consumption.
  • Easy maintenance.

Experience and knowledge

The experience of Eisbär as an established manufacturer with extensive practical knowledge and focus in understanding the customer requirements is an outstanding strength. The customer therefore has a flexible partner with Eisbär for new, competitive and energy-efficient tailor-made system solutions. Another important Eisbär competence is digitalisation and clearly structured visualisation as well as data connectivity of all operational data for efficient control and maintenance.
