ELECTRO-TECHNOLOGY FOR INDUSTRY
Water can save energy and
keep your enclosure cool
even under harsh conditions
PWS Series
Air/Water Heat Exchangers
The use of Pfannenberg air/water heat exchangers is particularly
suitable where ambient temperatures are high, the atmosphere
proves to be particularly oily or aggressive or where cooling units
(because of filter cleaning and maximum ambient temperatures)
can be a maintenance concern.
Their main advantages over other cooling units for control cabinets
are their maintenance-free operation and extremely low noise
emission.
By pulling heat away from the machine and plant and eliminating
redundant compressors, the end user can realize great energy
savings and not over tax existing building HVAC systems.
Ideal areas of use for air/water heat exchangers are wherever
machines or production processes are cooled by tempered water
and water is thus already provided.

Heat Exchangers
Reduce machine costs by utilizing existing chilled water
for a 100% complete system solution.
The combination of air/water heat exchangers and
chillers offers an ideal system solution for the cooling
of your processes, machines and controllers.
Chillers ensure central, economic cooling and provision
of water as the cooling medium. All cooling tasks in a
system or machine and also on a control cabinet can
be accomplished simply and economically via a closed
pipeline system.
The special product benefits
of the PWS series
Economy
• system compatible with chillers
• can be integrated in existing cooling circuits
• integrated thermostat and solenoid valve for energy efficient
temperature control
Environmental Protection
• very high IP protection, NEMA 3R/4 optional
• usable under aggressive environmental conditions
• independent from the ambient temperature at the place
of installation
Process reliability
• high air flow rate and cooling capacity
• any power losses that occur are not given off into the room
• integrated temperature monitoring with alarm contact
Service and ease of mounting
• compact design
• seal requires no elaborate reworking of the mounting cut-out
• maintenance free design
