Panels

  • Each of the panels is made up of 0.7mm pre-painted sheet and 1.0mm Zinc coated inner panel.
  • These panels are sandwiched with Rockwool insulation of uniform density (40 kg/m3) ensures low thermal conductivity and robust construction
  • Polyurethane foam can be given as optional

Blower Assembly

  • High energy efficient, fans with backward/forward curved blades with DIDW (double inlet double width) construction are available for various static pressure requirements
  • The motors are TEFC type with either IP54/IP55 protection and with class F insulation
  • Fan and Motor is mounted on a common extruded aluminum channel base, by using anti-vibration isolators
