Company Profile

The Austrian company Blue Air Systems, which is based in Kundl, in the Tyrol region, produces machinery for low energy mould dehumidifiying, high performance cooling and high efficient resin drying equipment.

Products

Dehumidifiying

When the surface temperature of an object sinks below the dew point of the ambient air, condensation builds on this object. Blue Air Systems’ DMS Dry Mould System create a dry climate around the mould.

• DMS - Dry Mould System
  • process air volume from 500 to 5.000 Nm³/h for single production machines
  • no need of chilled water
  • lowest energy consumption (Down beneath 0,0007 kW/m³)
  • steady product quality and production conditions throughout the year
  • higher machine efficiency through shorter cooling time
  • CFC free system
  • no service necessary (only filter)
• DMS - dry mould system
  • process air volume from 5000 to 15.000 Nm³/h for complete production lines and central systems
  • no need of chilled water
  • lowest energy consumption
  • steady product quality and production conditions throughout the year
  • higher machine efficiency through shorter cooling time
  • CFC free system
  • low maintenance expenses
  • quick return on investment

Cooling

The mould only removes heat from the outside surface of the container causes material stress and extended cooling time in the mould. Blue Air Systems’ Blow Air Cooling units replace the regular blowing air with chilled compressed air inside the container during the blowing process. As a result the heat is removed also from the inner surface of the container reducing material stress and cutting cooling time up to 50 %

• CAC Compressed Air Chiller
  • Process Air volume from 120 to 540 Nm³/h at -35°C compressed process air. The Compressed Air Chiller replaces the regular blowing air with chilled compressed air (- 35 °C) inside the container during the blowing process.
  • production increase up to 50 %
  • radical reduction of cooling time
  • quality increases through the constant cooling process
  • easy integration into production process with fully automatic operation
  • suitable for nearly all blow moulding machines
  • low energy consumption and maintenance expenses
  • quick return on investment between 1 month and 1 year
  • CFC free system

Drying

Humidity absorbed by resin or found on the surface of pellets causes troubles during production e.g. processing failure, surface defects or loss of mechanical properties. Blue Air Systems’ resin dryers use pre-dried air from the compressed air available on site network for the drying process which guarantees excellent results at a very low compressed air consumption.

• RDM Micro Resin Dryer
  • For throughputs up to 1.000 g/h. The MICRO Compressed Air Resin Dryer RDM (hopper size between 0,5 und 3 liters) is especially suitable for small material throughputs.
  • simple installation directly on the production machine
  • no interruption of the process chain
  • constant low dew point, no regeneration of process air
  • simple installation (“plug & play”)
  • low maintenance and energy requirement
  • adjustable material level sensor (conveying option)
  • flexible control of air volume
• RDX Resin Dryer
  • For throughputs from 1 to 300 kg/h
  • simple installation directly on the production machine
  • no interruption of the process chain
  • constant low dew point, no regeneration of process air
  • simple installation (“plug & play”)
  • 38 different hopper sizes form 7 to 92 litres
  • optional for 27, 42, 62 and 92 litres: dividable hoppers for optimal cleaning
  • low maintenance and energy requirements
  • adjustable material level sensor (conveying option)
  • intelligent compressed air volume control through sensors
• RDL Modular Resin Dryer
  • The Modular Resin Dryer RDL (hopper size up to 1.000 litres) is especially suitable for medium to large material throughputs (for throughputs from 30 to 500 kg/h).
  • improved, state-of-the-art compressed air technology for lowest energy consumption
  • guaranteed drying performance, due to constant, low dew point (throughout the year, in every weather, in every climate)
  • applicable for all resins, including PET
  • process air with - 25 °C dew point (if required a dew point of - 70 °C can be produced)
  • no chilled water needed
  • no minimum drying temperature
  • no moving parts
  • maintenance free
