Type MKA

For increased insertion loss and broadband attenuation even in the low frequency range

 

Energy-saving splitters with resonating panels, ready to be used in air conditioning systems

  • Attenuation effect due to resonance and absorption
  • Energy efficient due to aerodynamically profiled frame (radius > 15 mm)
  • Acoustic data measured to ISO 7235
  • Absorption material is biosoluble and hence hygienically safe
  • Absorption material faced with glass fibre fabric as a protection against erosion due to airflow velocities up to 20 m/s
  • Absorption material non-combustible, to EN 13501, fire rating class A1
  • Available in standard sizes and many intermediate sizes
  • Operating temperature up to 100 °C


Optional equipment and accessories

  • Additional perforated sheet metal to protect the absorption material
  • Powder-coated
  • Stainless steel
  • Brine and salt-water resistant aluminium construction (AlMg3)

  • Application
  • Description

Application

  • Sound attenuator splitters with resonating panels, Type MKA, used for the reduction of fan noise and air-regenerated noise in air conditioning systems
  • Attenuation effect due to absorption and resonance
  • Broadband attenuation even in the low frequency range of critical fan noise
  • Hygiene tested and certified to VDI 6022
  • For use in potentially explosive atmospheres (ATEX), zones 1, 2, 21 and 22 (outside)

Special characteristics

  • Resonating panels ensure increased insertion loss in the frequency range of critical fan noise
  • Up to 30 % lower differential pressure
  • Energy efficient and/or space saving due to aerodynamically profiled frame
  • Hygiene tested and certified
  • Multi-section construction available for large dimensions

Variants

  • MKA-100: Splitter thickness 100 mm
  • MKA-200: Splitter thickness 200 mm
  • MKA-230: Splitter thickness 230 mm

Construction

Surface of splitter area not covered by a resonating panel

  • F: Glass fibre fabric
  • L: Glass fibre fabric and perforated sheet metal

Parts and characteristics

  • Aerodynamically profiled frame
  • Absorption material and resonating panels fitted to reduce air-regenerated noise by absorption and resonance

Useful additions

  • Fitting accessories for sound attenuator splitters

Construction features

  • Aerodynamically profiled splitter frame (radius > 15 mm) that enables a reduction of turbulence both upstream and downstream; frame with grooves for increased rigidity
  • Frame edges are folded to protect the infill
  • Operating temperature up to 100 °C (construction with perforated sheet metal up to 300 °C for 3h max.)

Materials and surfaces

  • Splitter frames, partitioning panels and resonating panels made of galvanised sheet steel
  • Absorption material is mineral wool


Mineral wool

  • To EN 13501, fire rating class A1, non-combustible
  • RAL quality mark RAL-GZ 388
  • Biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EG
  • Faced with glass fibre fabric as protection against erosion through airflow velocities of up to 20 m/s
  • Inert to fungal and bacterial growth
