• The combination of width and height dimensions within the basic sizes offers flexibility in sizing the unit to fit into various on-site space requirements
• Fan and Motor assembly is mounted on a common base with suitable vibration isolators to ensure that they are isolated from the main case structure
• The ADS units are offered with double skin panels with 25mm/45mm thickness, fabricated from heavy gauge galvanized steel sheet dully finished with powder coat Fan and Motor assembly is mounted on a common base with suitable vibration Isolators to ensure that they are isolated from the main case structure
• Units are manufactured at an ISO 9001 certified facility center ensuring quality standards for the components used in construction of the units
• Powder coated outer panels are feature of ADS series; however blue skin panels are available as an option
• All components are standard and interchangeable
• Access panels are provided with easily removable fasteners to facilitate easy maintenance

Panels

• Each of the panels is made up of 0.7mm pre-painted sheet and 1.0mm Zinc coated inner panel
• These panels are inserted between 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

Coils

• Coils are sized and designed by the computerized software selection program and manufactured in our state- of- the- art technology plant and tested as per the test conditions specified by ARI 410 Standards Corrugated plate type fin is die-formed
