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.
