\St Liebert
The Liebert range of dry coolers has been designed
to complement and enhance the Company's wide
range of glycol-cooled precision air conditioning
systems.
These rugged heat rejected units feature advanced
fan blade design and a carefully developed cabinet
structure, which ensures maximum operating
efficiency yet minimises sound pressure levels.
All incorporate axial flow fans, with impeller and
motor, constructed as a single unit. The motor rotor
actually forms the hub of the impeller, creating an
aerodynamic shape which provides very efficient
performance. In addition, the airflow over the coil is
maximised by the bell mouth construction of the fan
inlets.
DESIGNED FOR MAXIMUM
OPERATING EFFICIENCY
The motor mounting is combined with the wire
guard grille to create a single component which fully
meets the requirements of DIN24 167 and DIN /1E 38.
• Optional advanced fan speed control kit
for glycol temperature regulation
• Corrosion resistant low maintenance
aluminium casing
• Refrigeration grade copper coils with
aluminium fins, tested to 440psi (30 bar)
• Weatherproof design
• Rotating stator axial flow fans ensure
vibration-free low noise operation
• Low sound levels from only 39dB(A) at
ten metres free-field
• High ambient selections available
• Factory assembled and tested to
ISO9001
