While most hospitals in the United States still utilize a single, massive air handling unit to serve 6-8 operating rooms at a time, the AirTUNNEL system simplifies control via utilization of a single unit per room. Smaller air handlers mean easier, quicker maintenance of units, significantly more affordable redundancy designs, less labor-intensive installations, and the elimination of complex supply-side VAV controls. Smaller air handling units run more efficiently than their larger counterparts, and are significantly more responsive.
AirTUNNEL units are double-wall with thermal break, and are provided with low-leak construction.
Outer and inner liners are available in various materials. Units are insulated with injected foam.
Access doors and aluminum checker plate floors are provided in all access sections.
Coils, filtration, humidification, and other components are customizable.
Smaller filter banks mean fast changes that can be performed by a single person. Supply and return fans have sealed bearings. Smaller coils are easy to handle and don't require much space.
The AirTUNNEL removes the need for supply-side VAV boxes. This means that no VAV control modules, damper actuators, or reheat coils are necessary, nor are the water piping or the associated wiring for each VAV box.
