Ingenia Custom Air Handling Solutions


Ingenia’s custom air handlers give the designer the broadest portfolio of options in the industry to provide solutions to the most unique situations. Ingenia air handlers can be configured to fit the most challenging spaces and difficult installations.

Whether your need is related to a limited footprint, acoustics, specialized ventilation-monitoring capabilities or humidity control, we can design and build your air handler to your exact specifications.

Ingenia’s custom air handling units are fully integrated systems that offer the same premium features as the Ingenia Modular AHU’s plus:

  • Air or water cooled DX A/C
  • Water source heat pumps
  • Indirect or direct fired gas heaters
  • Steam, hot water or electrical heat
  • Heat recovery with heat recovery wheel, flat plates or heat pipes
  • Hydronic piping manifolds or complete hydronic piping networks
  • Single or multi-point power connections
  • Programmable microprocessor controls

Features & benefits

Highest quality and performance indoor & outdoor air handlers

  • Pre-configured unit sizes with the ability to further modify cabinet dimensions with the Designer software, giving flexibility to match existing unit dimensions in retrofit applications. Output files can be PDF, AutoCad or REVIT®.
  • Units can be built in galvanized steel, all aluminum, all stainless steel or a combination of materials.
  • The highest energy-efficient air handlers in the industry with complete no-through metal construction on all base frames, floors, walls, doors and roof panels.
  • Polyurethane foam injected panels with R-values ranging from 13 to 26 depending on wall thicknesses.
  • Exterior and/or interior can be finished with a baked electrostatic powder coating, whereby all parts are coated before assembly to a minimum salt spray resistance of 10,000 hours.
  • Electrostatic antimicrobial powder coating for interior liners is available to meet the requirements of specialty markets such as healthcare, pharmaceutical and others. Minimum resistance to salt spray of 10,000 hours.
  • Complete interior wash-down option with water containment floors for healthcare, industrial and food processing applications. Floor drains available in all sections.
  • Inlet, discharge and radiated acoustical performances can be predicted with Ingenia's acoustic software.

Capacity & performance

1,000 to 200,000 CFM units customized to meet our customer’s needs.

    • Cabinets meet and exceed the AHRI standard 1350
    • Casing deflection rating class CD1
    • Casing air leakage rating class CL1
    • Casing thermal transmittance rating class CT1
    • Casing thermal bridging rating class CB0
  • Cabinet pressure resistance is rated and tested up to positive and/or negative 15” w.g.
  • Air leakage rate is tested to less than 0.5% at the rated cabinet pressure up to 15” w.g.
  • Wall deflection less than 1/240 at the rated cabinet pressure.
  • Exceptional uniform wall thermal resistance, R-value = 6.5/inch thickness.
  • Low noise NC-30 or NC-40 design. Acoustical performance can be enhanced with the use of Ingenia's acoustical absorption panel systems.
