Our custom air handling units offer solutions for the most challenging situations. These custom AHU’s can be configured to fit unusual spaces and difficult installations.
Ingénia Custom AHUs
Whether you have a limited footprint, or unique needs relating to acoustics, specialized ventilation-monitoring capabilities or humidity control, we can design and build your air handler to your precise specifications. Our custom air handling units are fully integrated systems that offer the same premium features as the Ingenia Modular AHU, along with:
- 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
