„Suspended“ PT series
Common features
• ESA control system
-Incorporates precision sensors that
guarantee optimised, dynamic adjustment
to the relevant performance requirements, fan
and compressor activated independently of
one another
-Allows energy-saving operation and consistent,
high-qual
• Stainless steel heat exchanger
-Nocorrosion
-Permanently smooth surfaces
Benefits:
-Long service life
-Consistently high air quality
-Nofuture increase in pressure loss
• Efficient heat transfer
-Precooled by cold air flow
-Excellent coolant distribution for efficient
cooling
-Large surfaces
Benefits:
-Energy savings
• Vertical attachment of heat exchanger
-Direct air guide
-Cleaned automatically by discharged
condensate
-Optimal condensate discharge
Benefits:
-Minimal pressure losses, low operating
costs
-Nocontamination, no increase in pressure
loss
-Condensate collected at lowest point

• Condensate separation
-Optimal flow speed for easy droplet formation
-Plate profile encourages bead formation
Benefits:
-Maximum degree of separation guaranteed
• Efficient, economical discharge without no
pressure losses due to automatic condensate
discharger (from DK 800 PT). DK 400 PT and
DK 600 PT with float diverters
• Heating compressed air
-Outgoing air flow cools the incoming air
Benefits:
-Energy-saving
• Generous connection dimensions adapted to
the flow rate
• Simple assembly on walls or floors
• Electrical connection 230 V/50 Hz (alternating
current)
• For continuous use and protecting highquality
machines and control systems
• Available while stocks last
• Energy-saving function
-Fan and compressor switch off ifair is not
drawn from the unit for acertain time
Benefits:
-More economical operation
• Version with float diverters
• Clear layout, easy to operate, ergonomic and
user-friendly
• Indicator for monitoring the pressure dew
point
• For protecting consumers (such as tools) in
various applications
