Cold compressed-air dryer series SD - Innovative quality product "Made in Germany"

Your advantages:

  • Very important energy saving
  • The new cold dryer control flexibly adapts the
    cooling capacity of the dryer to any requirement
    - even if the devices prepare the compressed-
    air of speed-controlled compressors
  • Inefficient by-pass control is omitted as the
    dryer even in partical load operation only consumes
    the energy which is in fact required for
    the preparation of the current compressed-air
    quantity (from SD 50).
  • Considerably reduced coolant filling
  • All cold dryers with the coolant R 134 a which
    is not harmful to atmospheric ozone
  • Compact construction
  • Low downstream pressure difference
  • Reliable use up to an environmental temperature
    of + 50°C (compact type: max. + 45°C)
  • Reliable and operationally safe
  • Innovative quality product
  • “Made in Germany”

Function of the cold compressed-air dryer:

  • The compressed-air is conducted to the cold
    compressed-air dryer for preparation and
    pre-cooled in the air / air heat exchanger. This
    pre-cooling takes place in the counter current
    flow of the escaping cooled compressed-air
    and is therefore working completely without
    any additional energy requirement.
  • The further cooling to the pressure dew point
    takes place in the coolant / air heat exchanger
    which is cooled by a coolant circuit. During
    the whole cooling process, the humidity of
    the compressed-air drops out as condensate
    and is automatically drained.
  • The prepared compressed-air is reheated in
    the air / air heat exchanger by the induced
    compressed-air before it escapes.
  • This way, we achieve a considerable energy
    saving.

In order to prevent from costly failures, the

compressed-air is to be dry, oil-free and

clean during production!

 

TRISAB-heat exchanger

  • The “core” of the new model range is the
    newly designed TRISAB heat exchanger (standard
    from 80 m3/h airflow onwards).
  • It distinguishes itself by a very large heat
    exchange surface. This guarantees an operation
    mode independent from the load.
  • The use of largely dimensioned flow channels
    allows extremely low pressure differences.
    the system has large overload reserves and
    works with a pressure dew point of + 3°C. It is
    possible to operate up to a dew point of
    +15°C. The unusually high separation grade
    may render the upstream cyclone separator
    unnecessary. the condensate which accumulates
    in the BURAN cold compressed-air
    dryers is drained off by compressed-air microprocessor
    controlled without loss.

The decisive advantages of the TRISAB

heat exchanger:

  • Largely dimensioned air / air - heat exchanger
  • Coolant / air heat exchanger with important
    power density
  • Integrated condensate separation system
  • Insensibility to soiling by largely dimensions
    flow channels
  • Low downstream pressure difference
  • Insensibility to corrosion by using aluminum
    of special production processes which have
    proven over decades.
  • Reliable function even in case of excess humidity
    at the compressed-air intake.
