Longlife computer

• Longlife computer have signifficant longer lifetime as they are protected against dust, humidity and fast temperature change.
• They dissipate not more power than necessary.
• They have either no fan or special fans with low rotation speed and up to 300.000 hours lifetime.
• The ventilation is either a closed loop or adds only a fraction of fresh into the cooling stream. Filter impove lifetime only if they are maintained. The best filter is no filter.
• They are electrical rugged and impervious to changes in the mains.
• Interfaces are isolated wherever possible.
• We are using metal cases. Almost no plastic is used.
• Cmos batteries are replaced to have a calculated lifetime beyond 10 years.

• closed loop circulation
  No external air at all is sucked into the unit.
• Cooling system reaches components in all areas including the corners - no "hot-spots".
• Made from 3mm extruded aluminium -
  extreme stable.
• Fast environmental temperature changes have very littel effect to the internal electronic.
• No change of mechanical dimension since 1995.
  A longlife also concerning design.
