Detailed Configuration:

Frame

• Penta-post extra heavy gauge aluminium profiles and strong fiber-reinforced PE corner connection forming the structural frame

• Superior mechanical strength and rigidity to the unit frame and to prevent any buckling or deformation
• Thermal bridge free design, the profiles filled with polyurethane foam for insulation
• Anodizing surface treatment for profiles, corrosion-resistant
• Stainless steel frame available

 Casing Panel and Insulation

• Double skin construction is provided by sandwich type panels  comprising inner and outer stainless steel skins and  polyurethane  foam with minimum 48kg/m3 density, providing a good thermal  and acoustical performance
• The gasket liner between the panels and frame ensures the air  leakage rate to comply with GB/T 14294 clean air conditioning  requirement
• The factory painted steel sheet covered with 6 insulation  coatings, complies to 500h salt spray testing, showing an  excellent corrosion protection performance

 Famous Brand Blower and Motor

• Fan selection based on the air flow and air static requirement is  done by fan selection software
• Direct driven/ belt driven, forward curve/ backward curve  centrifugal fans, and EC fan is available for option
• Nicotra, Kruger, Deton, Yilida is offered as option
• TEFC type motor, class F insulation and IP54 or IP55 protection,  energy saving and stable operation
• Mounted on an adjustable slide for belt tension adjustment
• Variable frequency drive (VFD) motor is available
• Siemens, ABB, WEG, TECO is offered as option

 Vibration Eliminator

• To reduce the transmission of vibration and noise, fan and motor are installed on an independent complete base frame
• The complete base frame is isolated by deflection type spring isolators
• This unique structure not only reduce the vibration and noise, but also protect fan and motor during transportation

High Efficiency Cooling and Heating Coil

• All coils calculation and selection is done by selection software to match the required conditions
• Large coil face area ensures maximum heat transfer rate
• All coils tested at 30bar pressure underwater 24 hours
• Various corrosion resistance coils for option:
    -Cooper tube with cooper fins coil
    -Epoxy coated fins coil
    -Electrophoresis fins coil
    -Heresite coated coil
